Ampicillin suspension is used for:

Treating infections caused by certain bacteria.

Ampicillin suspension is a penicillin antibiotic. It works by blocking the bacteria's cell wall growth, which kills the bacteria.

Do NOT use ampicillin suspension if:

  • you are allergic to any ingredient in ampicillin suspension or to any other penicillin antibiotic (eg, amoxicillin)
  • you are taking a tetracycline antibiotic (eg, doxycycline)
  • 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.

Before using ampicillin suspension:

Some medical conditions may interact with ampicillin suspension. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you are pregnant, planning to become pregnant, or are breast-feeding
  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have had a severe allergic reaction (eg, severe rash, hives, difficulty breathing, dizziness) to a cephalosporin (eg, cephalexin) or other beta-lactam antibiotic (eg, imipenem)
  • if you have kidney problems

Some MEDICINES MAY INTERACT with ampicillin suspension. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Allopurinol because the risk of skin rash may be increased
  • Heparin because the risk of bleeding may be increased
  • Probenecid because it may increase the risk of ampicillin suspension's side effects
  • Tetracyclines (eg, doxycycline) because they may decrease ampicillin suspension's effectiveness
  • Methotrexate because the risk of its side effects may be increased by ampicillin suspension
  • Anticoagulants (eg, warfarin) because their effectiveness may be decreased or the risk of their side effects may be increased by ampicillin suspension
  • Aminoglycosides (eg, gentamicin), oral contraceptives (eg, ethinyl estradiol/norethindrone), or live oral typhoid vaccine because their effectiveness may be decreased by ampicillin suspension

This may not be a complete list of all interactions that may occur. Ask your health care provider if ampicillin suspension may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use ampicillin suspension:

Use ampicillin suspension as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Take ampicillin suspension by mouth on an empty stomach at least 1 hour before or 2 hours after eating.
  • Shake well before each use.
  • Take ampicillin suspension with a full glass of water (8 oz/240 mL).
  • Use a measuring device marked for medicine dosing. Ask your pharmacist for help if you are unsure of how to measure your dose.
  • To clear up your infection completely, take ampicillin suspension for the full course of treatment. Keep using it even if you feel better in a few days.
  • If you miss a dose of ampicillin suspension, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use ampicillin suspension.

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.
  • Diabetes patients - Ampicillin suspension may cause the results of some tests for urine glucose to be wrong. Ask your doctor before you change your diet or the dose of your diabetes medicine.
  • Use ampicillin suspension with extreme caution in CHILDREN younger than 10 years old who have diarrhea or an infection of the stomach or bowel.
  • Caution is advised when using ampicillin suspension in NEWBORNS and INFANTS; they may be more sensitive to its effects
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using ampicillin suspension while you are pregnant. Ampicillin suspension is found in breast milk. Do not breast-feed while using ampicillin suspension.
