Ketoprofen is a non-steroidal anti-inflammatory drug. The chemical name for ketoprofen is 2-(3-benzoylphenyl)-propionic acid with the following structural formula:

Its empirical formula is C₁₆H₁₄O₃, with a molecular weight of 254.29. It has a pKa of 5.94 in methanol:water (3:1) and an n-octanol:water partition coefficient of 0.97 (buffer pH 7.4).

Ketoprofen is a white or off-white, odorless, nonhygroscopic, fine to granular powder, melting at about 95°C. It is freely soluble in ethanol, chloroform, acetone, ether and soluble in benzene and strong alkali, but practically insoluble in water at 20°C.

Each ketoprofen immediate-release capsule for oral administration contains 50 mg or 75 mg of ketoprofen, USP. In addition, each capsule contains the following inactive ingredients: colloidal silicon dioxide, D&C yellow #10 aluminum lake, FD&C blue #1 aluminum lake, FD&C blue #2 aluminum lake, FD&C red #40 aluminum lake, gelatin, lactose monohydrate, magnesium stearate, pharmaceutical glaze, propylene glycol, sodium lauryl sulfate, sodium starch glycolate, corn starch, synthetic black iron oxide and titanium dioxide. The 50 mg capsules also contain FD&C yellow #6 aluminum lake and the 75 mg capsules contain FD&C green #3 aluminum lake.

Each ketoprofen extended-release capsule for oral administration contains 200 mg of ketoprofen, USP. In addition, each capsule contains the following inactive ingredients: ammonium hydroxide, black iron oxide, D&C yellow #10 aluminum lake, dibutyl sebacate, ethylcellulose, FDA/E172 yellow iron oxide, FD&C blue #1 aluminum lake, FD&C blue #2 aluminum lake, FD&C red #40 aluminum lake, fumed silica, gelatin, hypromellose, maltodextrin, methacrylic acid copolymer type B, n-butyl alcohol, oleic acid, pharmaceutical glaze, polyacrylate dispersion, propylene glycol, SDA-3A alcohol, silicon dioxide, sodium lauryl sulfate, sugar spheres, talc, titanium dioxide, triacetin and triethyl citrate.

Ketoprofen is a non-steroidal anti-inflammatory drug with analgesic and antipyretic properties.

The anti-inflammatory, analgesic, and antipyretic properties of ketoprofen have been demonstrated in classical animal and in vitro test systems. In anti-inflammatory models ketoprofen has been shown to have inhibitory effects on prostaglandin and leukotriene synthesis, to have antibradykinin activity, as well as to have lysosomal membrane-stabilizing action. However, its mode of action, like that of other non-steroidal anti-inflammatory drugs, is not fully understood.

Ketoprofen is a racemate with only the S enantiomer possessing pharmacological activity. The enantiomers have similar concentration time curves and do not appear to interact with one another.

An analgesic effect-concentration relationship for ketoprofen was established in an oral surgery pain study with ketoprofen immediate-release capsules. The effect-site rate constant (K_e0) was estimated to be 0.9 hour^-1 (95% confidence limits: 0 to 2.1), and the concentration (Ce₅₀) of ketoprofen that produced one-half the maximum PID (pain intensity difference) was 0.3 mcg/mL (95% confidence limits: 0.1 to 0.5). Thirty-three (33) to 68% of patients had an onset of action (as measured by reporting some pain relief) within 30 minutes following a single oral dose in postoperative pain and dysmenorrhea studies. Pain relief (as measured by remedication) persisted for up to 6 hours in 26 to 72% of patients in these studies.

Carefully consider the potential benefits and risks of ketoprofen immediate-release capsules and ketoprofen extended-release capsules before deciding to use ketoprofen immediate-release capsules and ketoprofen extended-release capsules. Use of the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS).

Ketoprofen immediate-release capsules and ketoprofen extended-release capsules are indicated for the management of the signs and symptoms of rheumatoid arthritis and osteoarthritis.

Ketoprofen extended-release capsules are not recommended for treatment of acute pain because of its extended-release characteristics (see CLINICAL PHARMACOLOGY: Pharmacokinetics).

Ketoprofen immediate-release capsules are indicated for the management of pain. Ketoprofen immediate-release capsules are also indicated for treatment of primary dysmenorrhea.

Ketoprofen immediate-release capsules and ketoprofen extended-release capsules are contraindicated in patients who have shown hypersensitivity to ketoprofen.

Ketoprofen immediate-release capsules and ketoprofen extended-release capsules should not be given to patients who have experienced asthma, urticaria, or allergictype reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic reactions to ketoprofen have been reported in such patients (see WARNINGS: Anaphylactoid Reactions and PRECAUTIONS : General: Preexisting Asthma).

Ketoprofen immediate-release capsules and ketoprofen extended-release capsules are contraindicated for the treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS).

Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a non-steroidal anti-inflammatory drug may cause a dose dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greater risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state.

As with other NSAIDs anaphylactoid reactions may occur in patients without known prior exposure to ketoprofen immediate-release capsules or ketoprofen extended-release capsules. Ketoprofen immediate-release capsules or ketoprofen extended-release capsules should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (see CONTRAINDICATIONS and PRECAUTIONS: General: Preexisting Asthma). Emergency help should be sought in cases where an anaphylactoid reaction occurs.

NSAIDs, including ketoprofen immediate-release capsules and ketoprofen extended-release capsules, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity.

In late pregnancy, as with other NSAIDs, Ketoprofen immediate-release capsules and ketoprofen extended-release capsules should be avoided because it may cause premature closure of the ductus arteriosus.

Ketoprofen immediate-release capsules and ketoprofen extended-release capsules cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids.

If steroid dosage is reduced or eliminated during therapy, it should be reduced slowly and the patients observed closely for any evidence of adverse effects, including adrenal insufficiency and exacerbation of symptoms of arthritis.

The pharmacological activity of ketoprofen immediate-release capsules and ketoprofen extended-release capsules in reducing fever and inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, painful conditions.

Ketoprofen and other non-steroidal anti-inflammatory drugs cause nephritis in mice and rats associated with chronic administration. Rare cases of interstitial nephritis or nephrotic syndrome have been reported in humans with ketoprofen since it has been marketed.

A second form of renal toxicity has been seen in patients with conditions leading to a reduction in renal blood flow or blood volume, where renal prostaglandins have a supportive role in the maintenance of renal blood flow. In these patients, administration of a non-steroidal anti-inflammatory drug results in a dose dependent decrease in prostaglandin synthesis and, secondarily, in renal blood flow which may precipitate overt renal failure. Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics, and the elderly. Discontinuation of non-steroidal anti-inflammatory drug therapy is typically followed by recovery to the pretreatment state.

Since ketoprofen is primarily eliminated by the kidneys and its pharmacokinetics are altered by renal failure (see CLINICAL PHARMACOLOGY), patients with significantly impaired renal function should be closely monitored, and a reduction of dosage should be anticipated to avoid accumulation of ketoprofen and/or its metabolites (see DOSAGE AND ADMINISTRATION).

Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed.

• Ketoprofen immediate-release capsules or ketoprofen extended-release capsules, like other NSAIDs, may cause serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and should ask for medical advice when observing any indicative sign or symptoms. Patients should be apprised of the importance of this follow-up (see WARNINGS: Cardiovascular Effects).
• Ketoprofen immediate-release capsules and ketoprofen extended-release capsules, like other NSAIDs, can cause GI discomfort and rarely serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative sign or symptoms including epigastric pain, dyspepsia, melena, and hematemesis. Patients should be apprised of the importance of this follow-up (see WARNINGS: Gastrointestinal Effects: Risk of Ulceration, Bleeding, and Perforation).
• Ketoprofen immediate-release capsules and ketoprofen extended-release capsules, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalizations and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms of skin rash and bulers, fever, or other signs of hypersensitivity such as itching, and should ask for medical advice when observing any indicative signs or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible.
• Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians.
• Patients should be informed of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy.
• Patients should be informed of the signs of an anaphylactoid reaction (e.g., difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help (see WARNINGS).
• In late pregnancy, as with other NSAIDs, ketoprofen immediate-release capsules and ketoprofen extended-release capsules should be avoided because it may cause premature closure of the ductus arteriosus.

NSAIDs are often essential agents in the management of arthritis and have a major role in the treatment of pain, but they also may be commonly employed for conditions which are less serious. Physicians may wish to discuss with their patients the potential risks (see WARNINGS, PRECAUTIONS: General and ADVERSE REACTIONS) and likely benefits of NSAID treatment, particularly when the drugs are used for less serious conditions where treatment without NSAIDs may represent an acceptable alternative to both the patient and physician.

Because aspirin causes an increase in the level of unbound ketoprofen, patients should be advised not to take aspirin while taking ketoprofen (see PRECAUTIONS: Drug Interactions). It is possible that minor adverse symptoms of gastric intolerance may be prevented by administering ketoprofen immediate-release capsules with antacids, food or milk. Ketoprofen extended-release capsules have not been studied with antacids. Because food and milk do affect the rate but not the extent of absorption (see CLINICAL PHARMACOLOGY), physicians may want to make specific recommendations to patients about when they should take ketoprofen in relation to food and/or what patients should do if they experience minor GI symptoms associated with ketoprofen therapy.

Because serious GI tract ulceration and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs, should have their CBC and a chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (e.g., eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, ketoprofen immediate-release capsules and ketoprofen extended-release capsules should be discontinued.

The following drug interactions were studied with ketoprofen doses of 200 mg/day. The possibility of increased interaction should be kept in mind when ketoprofen immediate-release doses greater than 50 mg as a single dose or 200 mg of ketoprofen per day are used concomitantly with highly bound drugs.

Chronic oral toxicity studies in mice (up to 32 mg/kg/day; 96 mg/m²/day) did not indicate a carcinogenic potential for ketoprofen. The maximum recommended human therapeutic dose is 300 mg/day for a 60 kg patient with a body surface area of 1.6 m², which is 5 mg/kg/day or 185 mg/m²/day. Thus, the mice were treated at 0.5 times the maximum human daily dose based on surface area.

A 2 year carcinogenicity study in rats, using doses up to 6.0 mg/kg/day (36 mg/m²/day), showed no evidence of tumorigenic potential. All groups were treated for 104 weeks except the females receiving 6.0 mg/kg/day (36 mg/m²/day) where the drug treatment was terminated in week 81 because of low survival; the remaining rats were sacrificed after week 87. Their survival in the groups treated for 104 weeks was within 6% of the control group. An earlier 2 year study with doses up to 12.5 mg/kg/day (75 mg/m²/day) also showed no evidence of tumorigenicity, but the survival rate was low and the study was therefore judged inconclusive. Ketoprofen did not show mutagenic potential in the Ames Test. Ketoprofen administered to male rats (up to 9 mg/kg/day; or 54 mg/m²/day) had no significant effect on reproductive performance or fertility. In female rats administered 6 or 9 mg/kg/day (36 or 54 mg/m²/day), a decrease in the number of implantation sites has been noted. The dosages of 36 mg/m²/day in rats represent 0.2 times the maximum recommended human dose of 185 mg/m²/day (see above).

Abnormal spermatogenesis or inhibition of spermatogenesis developed in rats and dogs at high doses, and a decrease in the weight of the testes occurred in dogs and baboons at high doses.

The effects of ketoprofen on labor and delivery in pregnant women are unknown. Studies in rats have shown ketoprofen at doses of 6 mg/kg (36 mg/m²/day, approximately equal to 0.2 times the maximum recommended human dose) prolongs pregnancy when given before the onset of labor. Because of the known effects of prostaglandin-inhibiting drugs on the fetal cardiovascular system (closure of ductus arteriosus), use of ketoprofen during late pregnancy should be avoided.

It is not known whether this drug is excreted in human milk. Data on secretion in human milk after ingestion of ketoprofen do not exist. In rats, ketoprofen at doses of 9 mg/kg (54 mg/m²/day; approximately 0.3 times the maximum human therapeutic dose) did not affect perinatal development. Upon administration to lactating dogs, the milk concentration of ketoprofen was found to be 4 to 5% of the plasma drug level. As with other drugs that are excreted in milk, ketoprofen is not recommended for use in nursing mothers.

Safety and effectiveness in pediatric patients below the age of 18 have not been established.

As with any NSAIDs, caution should be exercised in treating the elderly (65 years and older). In pharmacokinetic studies, ketoprofen clearance was reduced in older patients receiving ketoprofen immediate-release capsules or ketoprofen extended-release capsules, compared with younger patients. Peak ketoprofen concentrations and free drug AUC were increased in older patients (see PHARMACOKINETICS: Special Populations). The glucuronide conjugate of ketoprofen, which can serve as a potential reservoir for the parent drug, is known to be substantially excreted by the kidney. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection. It is recommended that the initial dosage of ketoprofen immediate-release capsules or ketoprofen extended-release capsules should be reduced for patients over 75 years of age and it may be useful to monitor renal function (see DOSAGE AND ADMINISTRATION). In addition, the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Elderly patients may be more sensitive to the antiprostaglandin effects of NSAIDS (on the gastrointestinal tract and kidneys) than younger patients (see WARNINGS and PRECAUTIONS). In particular, elderly or debilitated patients who receive NSAID therapy seem to tolerate gastrointestinal ulceration or bleeding less well than other individuals, and most spontaneous reports of fatal GI events are in this population. Therefore, caution should be exercised in treating the elderly, and when individualizing their dosage, extra care should be taken when increasing the dose (see DOSAGE AND ADMINISTRATION).

In ketoprofen immediate-release capsules clinical studies involving a total of 1540 osteoarthritis or rheumatoid arthritis patients, 369 (24%) were ≥ 65 years of age, and 92 (6%) were ≥ 75 years of age. For ketoprofen immediate-release capsules acute pain studies, 23 (5%) of 484 patients were ≥ 60 years of age. In ketoprofen extended-release capsules clinical studies, 356 (42%) of 840 osteoarthritis or rheumatoid arthritis patients were ≥ 65 years of age, and less than 100 of these were ≥ 75 years of age. No overall differences in effectiveness were observed between these patients and younger patients.

The incidence of common adverse reactions (above 1%) was obtained from a population of 835 ketoprofen immediate-release capsules treated patients in double-blind trials lasting from 4 to 54 weeks and in 622 ketoprofen extended-release capsules treated (200 mg/day) patients in trials lasting from 4 to 16 weeks.

Minor gastrointestinal side effects predominated; upper gastrointestinal symptoms were more common than lower gastrointestinal symptoms. In crossover trials in 321 patients with rheumatoid arthritis or osteoarthritis, there was no difference in either upper or lower gastrointestinal symptoms between patients treated with 200 mg of ketoprofen extended-release capsules once a day or 75 mg of ketoprofen immediate-release capsules TID (225 mg/day). Peptic ulcer or GI bleeding occurred in controlled clinical trials in less than 1% of 1,076 patients; however, in open label continuation studies in 1,292 patients the rate was greater than 2%.

The incidence of peptic ulceration in patients on NSAIDs is dependent on many risk factors including age, sex, smoking, alcohol use, diet, stress, concomitant drugs such as aspirin and corticosteroids, as well as the dose and duration of treatment with NSAIDs (see WARNINGS).

Gastrointestinal reactions were followed in frequency by central nervous system side effects, such as headache, dizziness, or drowsiness. The incidence of some adverse reactions appears to be dose related (see DOSAGE AND ADMINISTRATION). Rare adverse reactions (incidence less than 1%) were collected from one or more of the following sources: foreign reports to manufacturers and regulatory agencies, publications, U.S. clinical trials, and/or U.S. post-marketing spontaneous reports.

Signs and symptoms following acute NSAID overdose are usually limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which are generally reversible with supportive care. Respiratory depression, coma, or convulsions have occurred following large ketoprofen overdoses. Gastrointestinal bleeding, hypotension, hypertension, or acute renal failure may occur, but are rare.

Patients should be managed by symptomatic and supportive care following an NSAID overdose. There are no specific antidotes. Gut decontamination may be indicated in patients with symptoms seen within 4 hours (longer for sustained-release products) or following a large overdose (5 to 10 times the usual dose). This should be accomplished via emesis and/or activated charcoal (60 to 100 g in adults, 1 to 2 g/kg in children) with a saline cathartic or sorbitol added to the first dose. Forced diuresis, alkalinization of the urine, hemodialysis or hemoperfusion would probably not be useful due to ketoprofen's high protein binding.

Case reports include twenty-six overdoses: 6 were in children, 16 in adolescents, and 4 in adults. Five of these patients had minor symptoms (vomiting in 4, drowsiness in 1 child). A 12 year-old girl had tonic-clonic convulsions 1 to 2 hours after ingesting an unknown quantity of ketoprofen and 1 or 2 tablets of acetaminophen with hydrocodone. Her ketoprofen level was 1128 mg/L (56 times the upper therapeutic level of 20 mg/L) 3 to 4 hours post ingestion. Full recovery ensued 18 hours after ingestion following management with intubation, diazepam, and activated charcoal. A 45 year-old woman ingested twelve 200 mg extended-release ketoprofen capsules and 375 mL vodka, was treated with emesis and supportive measures 2 hours after ingestion, and recovered completely with her only complaint being mild epigastric pain.

Carefully consider the potential benefits and risks of a ketoprofen immediate-release capsules and ketoprofen extended-release capsules and other treatment options before deciding to use ketoprofen immediate-release capsules and ketoprofen extended-release capsules. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS).

After observing the response to initial therapy with ketoprofen immediate-release capsules and ketoprofen extended-release capsules, the dose and frequency should be adjusted to suit an individual patient's needs.

Concomitant use of ketoprofen immediate-release capsules and ketoprofen extended-release capsules is not recommended.

If minor side effects appear, they may disappear at a lower dose which may still have an adequate therapeutic effect. If well tolerated but not optimally effective, the dosage may be increased. Individual patients may show a better response to 300 mg of ketoprofen immediate-release capsules daily as compared to 200 mg, although in well controlled clinical trials patients on 300 mg did not show greater mean effectiveness. They did, however, show an increased frequency of upper and lower GI distress and headaches. It is of interest that women also had an increased frequency of these adverse effects compared to men. When treating patients with 300 mg/day, the physician should observe sufficient increased clinical benefit to offset potential increased risk.

In patients with mildly impaired renal function, the maximum recommended total daily dose of ketoprofen immediate-release capsules or ketoprofen extended-release capsules is 150 mg. In patients with a more severe renal impairment (GFR less than 25 mL/min/1.73 m² or end-stage renal impairment), the maximum total daily dose of ketoprofen immediate-release capsules or ketoprofen extended-release capsules should not exceed 100 mg.

In elderly patients, renal function may be reduced with apparently normal serum creatinine and/or BUN levels. Therefore, it is recommended that the initial dosage of ketoprofen immediate-release capsules or ketoprofen extended-release capsules should be reduced for patients over 75 years of age (see PRECAUTIONS: Geriatric Use).

It is recommended that for patients with impaired liver function and serum albumin concentration less than 3.5 g/dL, the maximum initial total daily dose of ketoprofen immediate-release capsules or ketoprofen extended-release capsules should be 100 mg. All patients with metabolic impairment, particularly those with both hypoalbuminemia and reduced renal function, may have increased levels of free (biologically active) ketoprofen and should be closely monitored. The dosage may be increased to the range recommended for the general population, if necessary, only after good individual tolerance has been ascertained.

Because hypoalbuminemia and reduced renal function both increase the fraction of free drug (biologically active form), patients who have both conditions may be at greater risk of adverse effects. Therefore, it is recommended that such patients also be started on lower doses of ketoprofen immediate-release capsules or ketoprofen extended-release capsules and closely monitored.

The recommended starting dose of ketoprofen in otherwise healthy patients is for ketoprofen immediate-release capsules 75 mg three times or 50 mg four times a day, or for ketoprofen extended-release capsules 200 mg administered once a day. Smaller doses of ketoprofen immediate-release capsules or ketoprofen extended-release capsules should be utilized initially in small individuals, or in debilitated or elderly patients. The recommended maximum daily dose of ketoprofen is 300 mg/day for ketoprofen immediate-release capsules or 200 mg/day for ketoprofen extended-release capsules.

Dosages higher than 300 mg/day of ketoprofen immediate-release capsules or 200 mg/day of ketoprofen extended-release capsules are not recommended because they have not been studied. Concomitant use of ketoprofen immediate-release capsules and ketoprofen extended-release capsules is not recommended. Relatively smaller people may need smaller doses.

As with other non-steroidal anti-inflammatory drugs, the predominant adverse effects of ketoprofen are gastrointestinal. To attempt to minimize these effects, physicians may wish to prescribe that ketoprofen immediate-release capsules or ketoprofen extended-release capsules be taken with antacids, food, or milk. Although food delays the absorption of both formulations (see CLINICAL PHARMACOLOGY) in most of the clinical trials ketoprofen was taken with food or milk.

Physicians may want to make specific recommendations to patients about when they should take ketoprofen immediate-release capsules or ketoprofen extended-release capsules in relation to food and/or what patients should do if they experience minor GI symptoms associated with either formulation.

The usual dose of ketoprofen immediate-release capsules recommended for mild to moderate pain and dysmenorrhea is 25 to 50 mg every 6 to 8 hours as necessary. A smaller dose should be utilized initially in small individuals, in debilitated or elderly patients, or in patients with renal or liver disease (see PRECAUTIONS: General). A larger dose may be tried if the patient's response to a previous dose was less than satisfactory, but doses above 75 mg have not been shown to give added analgesia. Daily doses above 300 mg are not recommended because they have not been adequately studied. Because of its typical non-steroidal anti-inflammatory drug-side effect profile, including as its principal adverse effect GI side effects (see WARNINGS and ADVERSE REACTIONS), higher doses of ketoprofen immediate-release capsules should be used with caution and patients receiving them observed carefully.

Ketoprofen extended-release capsules are not recommended for use in treating acute pain because of its extended-release characteristics.

What is the most important information I should know about medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)?

NSAID medicines may increase the chance of a heart attack or stroke that can lead to death. This chance increases:

• with longer use of NSAID medicines
• in people who have heart disease

NSAID medicines should never be used right before or after a heart surgery called a "coronary artery bypass graft (CABG)."

NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. Ulcers and bleeding:

• can happen without warning symptoms
• may cause death

The chance of a person getting an ulcer or bleeding increases with:

• taking medicines called "corticosteroids" and "anticoagulants"
• longer use
• smoking
• drinking alcohol
• older age
• having poor health

NSAID medicines should only be used:

• exactly as prescribed
• at the lowest dose possible for your treatment
• for the shortest time needed

What are Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)?

NSAID medicines are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as:

• different types of arthritis
• menstrual cramps and other types of short-term pain

Who should not take a Non-Steroidal Anti-Inflammatory Drug (NSAID)?

Do not take an NSAID medicine:

• if you had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID medicine
• for pain right before or after heart bypass surgery

Tell your healthcare provider:

• about all of your medical conditions.
• about all of the medicines you take. NSAIDs and some other medicines can interact with each other and cause serious side effects. Keep a ul of your medicines to show to your healthcare provider and pharmacist.
• if you are pregnant. NSAID medicines should not be used by pregnant women late in their pregnancy.
• if you are breastfeeding. Talk to your doctor.

What are the possible side effects of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)?

Get emergency help right away if you have any of the following symptoms:

• shortness of breath or trouble breathing
• chest pain
• weakness in one part or side of your body
• slurred speech
• swelling of the face or throat

Stop your NSAID medicine and call your healthcare provider right away if you have any of the following symptoms:

• nausea
• more tired or weaker than usual
• itching
• your skin or eyes look yellow
• stomach pain
• flu-like symptoms
• vomit blood
• there is blood in your bowel movement or it is black and sticky like tar
• unusual weight gain
• skin rash or bulers with fever
• swelling of the arms and legs, hands and feet

These are not all the side effects with NSAID medicines. Talk to your healthcare provider or pharmacist for more information about NSAID medicines.

Other information about Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

Aspirin is an NSAID medicine but it does not increase the chance of a heart attack. Aspirin can cause bleeding in the brain, stomach, and intestines. Aspirin can also cause ulcers in the stomach and intestines. Some of these NSAID medicines are sold in lower doses without a prescription (over-the-counter). Talk to your healthcare provider before using over-the-counter NSAIDs for more than 10 days.
