WHY is this medicine prescribed?
Ampicillin injection is used to treat certain infections that are caused by bacteria such as meningitis (infection of the membranes that surround the brain and spinal cord) and lung, blood, heart, urinary tract, and gastrointestinal tract infections. Ampicillin injection is in a class of medications called penicillins. It works by killing bacteria.
Antibiotics such as ampicillin injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
HOW should this medicine be used?
Ampicillin injection comes as a powder to be mixed with fluid and injected intravenously (into a vein) or intramuscularly (into a muscle). The frequency and length of your treatment depends on the type of infection you have.
You may receive ampicillin injection in a hospital or you may administer the medication at home. If you will be receiving ampicillin injection at home, your healthcare provider will show you how to use the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions.
You should begin to feel better during the first few days of treatment with ampicillin injection. If your symptoms do not improve or get worse, call your doctor.
Use ampicillin injection until you finish the prescription, even if you feel better. If you stop using ampicillin injection too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Are there OTHER USES for this medicine?
Ampicillin injection is also used in some pregnant women to prevent passing an infection to the baby during birth. Ampicillin injection is also sometimes used to prevent infection in people who are having certain types of surgery. Talk to your doctor about the risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

What SIDE EFFECTS can this medicine cause?

What should I know about STORAGE and DISPOSAL of this medication?
