Augmentin (amoxicillin and clavulanate potassium) is a prescription antibiotic that is licensed to treat various types of infections. Keflex (cephalexin) is typically used to treat common bacterial infections.
The most common side effects of Augmentin include:
* Diarrhea or loose stools -- in up to 9 percent of people
* Nausea -- up to 3 percent
* Vomiting -- up to 1 percent.
More serious side effects of Augmentin NEED TO BE REPORTED to the physician ASAP. Signs of an allergic reaction, including unexplained rash, hives, itching, unexplained swelling, wheezing, or difficulty breathing or swallowing...are one such symptom.
The same is true for Keflex. Hives, severe or watery diarrhea, bloody stools, throat or mouth sores, unexplained bleeding or bruising, rashes etc. Symtpoms such as itching and wheezing, difficulty breathing or swallowing and swelling of the throat also need to be reported.
Good luck to your sister! She needs to talk to a physician ASAP.
