Ampicillin belongs to the group of medications called antibiotics, or more specifically penicillins. It is used alone or in combination with other antibiotics to treat and prevent infections (e.g., bladder infections, heart valve infections) caused by certain types of bacteria. Teva Ampicillin works by killing the bacteria or preventing their growth.
Under normal circumstances, your infection should begin to improve (reduced symptoms, temperature, etc.) within 24 to 48 hours. If you find this is not the case, contact your doctor.
Like other antibiotics, ampicillin is not effective against viruses such as those that cause The Common Cold.
Your doctor may have suggested Teva Ampicillin for conditions other than those listed in these drug information articles. As well, some forms of Teva Ampicillin may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are using Teva Ampicillin, speak to your doctor. Do not stop using Teva Ampicillin without consulting your doctor.
Do not give Teva Ampicillin to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use Teva Ampicillin if their doctor has not prescribed it.
The dose and number of doses per day of ampicillin depend on the type of infection being treated or prevented. For most infections, the dose is usually given every 6 hours. To prevent heart valve infections, the usual adult dose is 2 grams as a single dose that is given 30 to 60 minutes before the procedure. For children and infants, the dose is usually based on body weight.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.
Ampicillin capsules and liquid are best taken with a full glass (8 ounces) of water on an empty stomach (either 1 hour before or 2 hours after meals) unless otherwise directed by your doctor. Shake the liquid form of Teva Ampicillin well before each use and use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.
Ampicillin must be taken for the recommended duration of treatment, even if you are feeling better.
It is important to use Teva Ampicillin exactly as prescribed by your doctor. If you miss a dose, use it as soon as possible so that levels of the antibiotic will be kept as constant as possible in the blood and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not use a double dose to make up for a missed one.
Store the liquid form of ampicillin in the refrigerator, do not allow it to freeze and keep it out of the reach of children. Any portion of refrigerated medication that has not been consumed within 21 days should be discarded. Liquid ampicillin that has been left at room temperature is good for 7 days only.
Store the capsule form of the medication at room temperature away from heat and direct light and keep it out of the reach of children. Do not store ampicillin in the bathroom or near the kitchen sink, as moisture may cause the medication to break down.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
Many medications can cause side effects. A side effect is an unwanted response to a medication when it is taken in normal doses. Side effects can be mild or severe, temporary or permanent.

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with Teva Ampicillin. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Teva Ampicillin.
Allergy: Allergic reactions to ampicillin are more common if you have a history of hay fever, hives, and other allergies. Reactions may include symptoms such as itching, hives, congestion, nausea, cramping, or diarrhea. Although much less common, more severe allergic reactions may include shortness of breath and swelling of the throat. If you experience these symptoms after taking Teva Ampicillin, stop taking the medication and get immediate medical attention.
If you have an allergy to this or related medications (e.g., penicillin, cephalexin), you should inform anyone involved with your medical care (e.g., doctor, pharmacist, nurse) and carry or wear easily accessible identification (such as a bracelet or necklace) alerting caregivers to the fact that your are allergic to penicillins.
Some people are "sensitive" (mild rash, upset stomach, etc.) to penicillins (e.g., amoxicillin, penicillin, ampicillin) while others are truly "allergic" (see symptoms above). As there may be times when it is most preferable to treat with penicillin (even if a person is "sensitive"), your doctor may test you to determine if you are truly allergic to this family of medications.
Blood cells: When ampicillin is taken for long periods of time, it can affect the amount of white blood cells, red blood cells, and platelets in the blood. If you are taking Teva Ampicillin for a long time, your doctor will monitor for this with blood tests.
Kidney function: If you have reduced kidney function, discuss with your doctor how Teva Ampicillin may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Ampicillin, and whether any special monitoring is needed.
Liver function: Teva Ampicillin may affect your liver function if you take it for long periods of time. Your doctor will monitor for this with blood tests if needed.
Severe diarrhea: As with other antibiotics, ampicillin may cause severe diarrhea that is associated with a bacteria called C. difficile or colitis (inflammation of the colon). If you develop severe diarrhea, especially if it contains blood or mucus, stop taking Teva Ampicillin and contact your doctor immediately.
Skin rash: People with Infectious Mononucleosis, acute lymphocytic Leukemia (ALL), or cytomegalovirus (CMV) infection are more likely to experience a rash from ampicillin.
If you have any of these conditions, discuss with your doctor how Teva Ampicillin may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva Ampicillin, and whether any special monitoring is needed.
Pregnancy: Ampicillin is safe to use during pregnancy.
