Why is this medication prescribed?

Ampicillin is used to treat bacterial infections in the throat, sinuses, lungs, reproductive organs, urinary system, and gastrointestinal tract. It is also used to treat meningitis, an infection of the membranes that surround the brain and spinal cord. Ampicillin belongs to the penicillin drug class. It eliminates bacteria to operate.

Colds, the flu, and other viral diseases cannot be treated with antibiotics like ampicillin. Antibiotic use that is not necessary raises the likelihood of developing a later infection that is resistant to antibiotic treatment.

How should this medicine be used?

Ampicillin is available as a liquid solution and pill for oral consumption. It is often taken three to four times a day, either 30 minutes prior to or two hours following meals. The sort of infection you have will determine how long your therapy will last. Take ampicillin every day at roughly the same time. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Follow the ampicillin directions exactly. Never take it in larger or less amounts or more frequently than directed by your doctor.

Before each use, thoroughly shake the suspension to combine the medication.

A full glass of water should be consumed along with the medication.

During the first several days of ampicillin treatment, you should start to feel better. Call your doctor if your symptoms don’t go away or get worse.

Even if you feel better, continue taking the ampicillin until the prescription is finished. Your illness could not be entirely treated if you stop taking ampicillin too soon or skip doses, and the bacteria might develop an antibiotic resistance.

Other uses for this medicine

What side effects can this medication cause?

Ampicillin could have negative effects. If any of these symptoms are severe or do not go away, let your doctor know right once:

Some adverse effects can be very harmful. Stop using ampicillin and contact your doctor right away if you have any of the following symptoms, or seek emergency medical attention:

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. The capsules should be kept at room temperature, away from sources of extreme heat and moisture (not in the bathroom). Keep the suspension well covered in the refrigerator, and after 14 days, discard any unused suspension. Avoid freezing.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medicines website at for additional information.

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

In case of emergency/overdose

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Additionally, information can be found online at Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

What other information should I know?

Keep all of your appointments with your physician and the lab. To determine how you are responding to ampicillin, your doctor may prescribe specific lab tests.

Use Clinistix or TesTape (not Clinitest) to test your urine for sugar if you have diabetes and are taking this medicine.

No one else should take your medication. It’s likely that your prescription cannot be renewed. Call your doctor if you continue to experience infection symptoms after taking the ampicillin is finished.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
