Possible Side Effects of Amoxicillin
For recently approved medications, very specific information about side effects is available. However, for older medications (such as amoxicillin), the prescribing information provides only vague side effect information. Based on this information, possible bothersome (but usually not dangerous) side effects of amoxicillin may include:
- Nausea and vomiting
- A black, hairy tongue
- Tooth discoloration
- Vaginal yeast infection.
The tooth discoloration (brown, yellow, or gray staining) usually occurs in children and usually improves (or is eliminated) with tooth brushing or cleaning.
It is possible that you may experience some or none of the amoxicillin side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking amoxicillin or if something "just does not seem right." While it may not be a side effect of amoxicillin, your healthcare provider will be able to diagnose and treat the problem.
