Aminobenzylpenicillin : Uses, Side Effects, Interactions & More
Why is this medication prescribed?
Aminobenzylpenicillin (Ampicillin) is used to treat certain infections caused by bacteria such as meningitis (infection of the membranes that surround the brain and spinal cord); and infections of the throat, sinuses, lungs, reproductive organs, urinary tract, and gastrointestinal tract. Aminobenzylpenicillin (Ampicillin) belongs to a class of medications called penicillins. It works by killing bacteria.
Antibiotics like Aminobenzylpenicillin don’t work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases the risk of getting an infection later that resists antibiotic treatment.
How should this medicine be used?
Aminobenzylpenicillin (Ampicillin) comes as a capsule and a suspension (liquid) to take by mouth. It is usually taken three to four times a day, either half an hour before or two hours after meals. The length of your treatment depends on the type of infection you have. Take Aminobenzylpenicillin at around the same times every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Take Aminobenzylpenicillin exactly as directed. Do not take more or less, or take it more often than prescribed by your doctor.
Shake the suspension well before each use to mix the medicine evenly.
The medicine should be taken with a full glass of water.
You should start to feel better during the first few days of treatment with Aminobenzylpenicillin. If your symptoms don’t improve or get worse, call your doctor.
Take Aminobenzylpenicillin until the prescription is finished, even if you feel better. If you stop taking Aminobenzylpenicillin too soon or miss doses, your infection may not be fully treated and the bacteria may become resistant to antibiotics.

What should I know about storage and disposal of this medication?
Keep this medicine in the container it came in, tightly closed, and out of the reach of children. Store the capsules at room temperature and away from excess heat and moisture (not in the bathroom). Keep the suspension in the refrigerator, tightly closed, and discard the unused suspension after 14 days. Do not freeze.
Unnecessary medications must be disposed of in special ways to ensure they cannot be consumed by pets, children, and others. However, you should not flush this medicine down the toilet. Instead, the best way to dispose of your medications is through a drug take-back program. Talk to your pharmacist or contact your local garbage / recycling department to find out about take-back programs in your community. See the FDA Safe Drug Disposal website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medicines out of the sight and reach of children, since many containers (such as those containing weekly pills and those for eye drops, creams, patches and inhalers) are not resistant to children and small children can easily open them. To protect young children from poisoning, always close the safety caps and immediately place the medicine in a safe place, one that is upright and out of their sight and reach. http://www.upandaway.org
