Penicillin, amoxicillin, and other antibiotics are used to treat GAS infections. To prevent complications, it is important to take the full course of the prescribed antibiotics.
Antibiotics can cause stomach upset and allergic reactions.
Most GAS infections respond rapidly to treatment. Once the antibiotics are finished and symptoms resolve, no further treatment is usually needed. Additional treatment may be needed if the person has complications such as rheumatic fever.
Usually, monitoring is only short-term, to make sure the infection has cleared. Other monitoring may be needed for more serious infections or complications. Any new or worsening symptoms should be reported to the healthcare provider.
