Ampicillin is an antibiotic in the penicillin family. It works by blocking bacteria from building their protective walls, and it is commonly used to treat infections of the throat, ears, urinary tract, and lungs.

What Ampicillin is

Ampicillin is an antibiotic medicine.

It works by stopping bacteria from forming a strong wall around themselves. This helps your body clear the infection.

Your doctor may prescribe it as capsules, a liquid, or a dissolvable tablet. The exact form depends on your age, weight, and the infection being treated.

What conditions it treats

Ampicillin can treat many infections caused by bacteria that respond to it. It is not effective against viruses.

Common targets include throat infections, sinus infections, ear infections, and pneumonia. It can also help with certain urinary tract infections and stomach or intestinal infections.

Your doctor decides if ampicillin is right for you. They consider the infection type and the bacteria involved.

Practical usage guide — timing, food, missed doses, storage

Take it exactly as prescribed. Do not change the dose or stop early, even if you feel better.

Take the medicine at regular times. This helps keep a steady amount in your body.

Food and drink guidelines. You may take ampicillin with or without food unless your doctor says otherwise. If you have stomach upset, a small snack can help. Do not crush or chew capsules. Missed doses and storage. If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed one. Do not double the dose. Store the medicine away from moisture and heat, and keep it out of reach of children. If you use a liquid, refrigerate after mixing and follow the label for how long it stays good.

What to watch for — side effects in plain language

Common side effects include upset stomach, diarrhea, nausea, or vomiting. You may also get a headache or a skin rash.

Less common but important reactions include severe allergic symptoms. Seek urgent help if you have swelling of the face or throat, trouble breathing, or a very bad skin rash. Tell your doctor about persistent diarrhea, white patches in your mouth, or unusual vaginal itching.

When to consult a doctor

Call your clinician if your symptoms get worse or do not improve after a few days.

Tell your doctor about all medicines you take, whether you are pregnant or breastfeeding, and any medical conditions you have. This helps prevent interactions and keeps you safe.
