Antibiotics. If you or your child has strep throat, your doctor will likely prescribe an oral antibiotic such as penicillin, amoxicillin (Amoxil, Trimox), azithromycin (Zithromax), clarithromycin (Biaxin), clindamycin (Cleocin) or a cephalosporin (Keflex, Ceclor). Penicillin may be given by injection in some cases — such as if you have a young child who is having a hard time swallowing or is vomiting from strep throat.
These antibiotics reduce the duration and severity of symptoms, as well as the risk of complications and the likelihood that infection will spread to classmates or family members.
Once treatment begins, you or your child should start feeling better in just a day or two. Call your doctor if you or your child doesn't feel better after taking antibiotics for 48 hours. If children on antibiotic therapy feel well and don't have a fever, they often can return to school or child care when they're no longer contagious — usually 24 hours after beginning treatment. But be sure to finish the entire course of medicine. Stopping medication early may lead to recurrences and serious complications, such as rheumatic fever or kidney inflammation.
- Pain relievers. In addition to antibiotics, your doctor may suggest ibuprofen (Advil, Motrin, others) or acetaminophen (Tylenol, others) to relieve throat pain and reduce fever. Because of the risk of Reye's syndrome, a potentially life-threatening illness, don't give aspirin to young children and teenagers. Be careful with acetaminophen, too. Taken in large doses, it can cause liver problems. Read and follow label directions. Talk to your doctor or pharmacist if you have questions.
