Typically : Typically it is recommended that you take antibiotics after eating. Taking the medication on an empty stomach is an invitation to an upset stomach especially if it mixes with the acid in your stomach. Try eating something a half hour prior to taking the medication. If this continues discuss it with your dentist to see if they can change to another antibiotic. Are you taking pain medications at the same time? If so that is an additional reason that you are experiencing GI upset. One additional note, this is probably not an allergy as is typically thought by patients.

Penicillin : Penicillin is a fungal poison that stops bacteria from multiplying near the fungus protecting it from the incursion of the bacteria. It is not surprising therefore to find that when we place it undiluted into our stomachs it makes us feel ill. You do really need to make sure that there is food in the stomach to dilute the effects of the antibiotic. You might also be allergic to penicillin. You might want to check this out with your doctor.
