==Side effects==
Ampicillin is comparatively less toxic than other antibiotics, and side effects are more likely in those who are sensitive to penicillins and those with a history of [[asthma]] or [[allergies]].<ref name="dailymed" /> In very rare cases, it causes severe side effects such as [[angioedema]], anaphylaxis, and ''[[C. difficile]]'' infection (that can range from mild [[diarrhea]] to serious [[pseudomembranous colitis]]).<ref name="dailymed" /> Some develop [[Black hairy tongue|black "furry" tongue]]. Serious adverse effects also include [[seizure]]s and [[serum sickness]]. The most common side effects, experienced by about 10% of users are diarrhea and rash. Less common side effects can be [[nausea]], [[vomiting]], [[itching]], and blood [[dyscrasia#Modern use|dyscrasia]]s. The gastrointestinal effects, such as hairy tongue, nausea, vomiting, diarrhea, and colitis, are more common with the oral form of penicillin.<ref name="dailymed" /> Other conditions may develop up several weeks after treatment.<ref name=AHFS2015/>
