Once at home, a person may have effects as a result of the procedure or injury, but usually not as a result of the medication used for dissociative anesthesia.
When the medication is wearing off, a person may have frightening dreams or hallucinations. Dissociative anesthesia is generally avoided in a person with a psychosis because it can cause severe anxiety. Other problems are rare, although allergic reactions to the anesthesia are possible.
The American Society of Anesthesiologists recently issued a warning about the potential side effects and interactions of herbal remedies with medications used before, during, and after surgery. The group recommends discontinuing all herbal remedies and supplements at least two weeks before planned surgery.
