Cefprozil Side Effects
In clinical trials, some of the most commonly reported side effects of cefprozil included nausea, diarrhea, and vomiting. Potentially serious reactions, such as seizures and bloody diarrhea, were also reported. If you are taking this medication and develop anything that "just does not seem right," let your healthcare provider know right away.
Just like any medicine, cefprozil (Cefzil®) can cause side effects. However, not everyone who takes the drug will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with cefprozil. Your healthcare provider can discuss a more complete list with you.)
Some cefprozil side effects are potentially serious and should be reported immediately to your healthcare provider. These include but are not limited to:
- Signs of an overdose, such as:
- Unusual muscle movements or hyperactivity
- Watery or bloody diarrhea, which may start while taking the drug or even quite a while after treatment ends
- Signs of an allergic reaction, such as:
- An unexplained rash
- Redness of the face
- Swelling of the mouth or throat
- Difficulty breathing.
Cefprozil has been studied extensively in clinical trials. In these studies, the possible side effects were carefully documented.
In these studies, the most common side effects of cefprozil included:
- Nausea -- in up to 3.5 percent of people
- Diarrhea -- up to 2.9 percent
- Genital itching and vaginal infection or irritation (such as a yeast infection) -- up to 1.6 percent
- Diaper rash -- up to 1.5 percent
- Vomiting -- up to 1 percent
- Abdominal (stomach) pain -- up to 1 percent
- Dizziness -- up to 1 percent.
Various laboratory test abnormalities, such as high liver enzymes, have also been reported with cefprozil.
