- you have mononucleosis ("mono")
- you have recently received or will be receiving live oral typhoid vaccine
Contact your doctor or health care provider right away if any of these apply to you.

Important safety information:
- Ampicillin suspension only works against bacteria; it does not treat viral infections (eg, the common cold).
- Be sure to use ampicillin suspension for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
- Long-term or repeated use of ampicillin suspension may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.
- If vomiting or diarrhea occurs, you will need to take care not to become dehydrated. Contact your doctor for instructions.
- Mild diarrhea is common with antibiotic use. However, a more serious form of diarrhea (pseudomembranous colitis) may rarely occur. This may develop while you use the antibiotic or within several months after you stop using it. Contact your doctor right away if stomach pain or cramps, severe diarrhea, or bloody stools occur. Do not treat diarrhea without first checking with your doctor.
- Hormonal birth control (eg, birth control pills) may not work as well while you are using ampicillin suspension. To prevent pregnancy, use an extra form of birth control (eg, condoms).
- Ampicillin suspension may interfere with certain lab tests. Be sure your doctor and lab personnel know you are using ampicillin suspension.
