What are the side effects of tetracyclines?
The most common side effects are stomach cramps or a burning sensation in the stomach, mild diarrhea, nausea, or vomiting. These problems usually go away as the body adjusts to the drug and do not require medical treatment. Less common side effects, such as sore mouth or tongue and itching of the rectal or genital areas also may occur and do not need medical attention unless they do not go away or they are bothersome. Other rare side effects may occur. Anyone who has unusual symptoms during or after treatment with tetracyclines should get in touch with his or her physician. Source: The Gale Group.
