Signs of severe reaction that warrant immediate medical attention include rash, hives, difficulty breathing, bloody stools, stomach pain, or swelling of the face, tongue or lips.

Drugs.com reveals that ampicillin is contraindicated in some people, including those who are taking a tetracycline antibiotic, those who have mononucleosis, or those who have received or plan to receive live oral typhoid vaccine. Other medications, vitamins and herbal supplements may interact with ampicillin by decreasing its effectiveness or increasing the risk of side effects.
