Dear Leona,
I think you mean Clavulin, which is the trade name for amoxicillin, an antibiotic.
The most common side effects are diarrhea and allergic reactions. If you have severe diarrhea, please notify your physician. If you have mild diarrhea it is okay to take an anti diarrheal such as kaopectate. If you are allergic to penicillin, do not take this drug, as it is in the penicillin family. If you have itching skin, hives please notify your doctor. In the rare chance that you have difficulty breathing, notify 911 immediately as you could be having an anaphylactic reaction.
Here is a link to a page that goes into greater detail and lists all the possible, though less likely side effects:

I hope you find this helpful. If not, please clarify your question. Otherwise, please press the ACCEPT button.
Take care,
