What is Ampicillin?
Ampicillin is a beta-lactam antibiotic, a medicine that kills bacteria. The active ingredient ampicillin stops the growth of cell walls in bacteria, preventing them from reproducing. This makes it possible to treat infections in the body that are caused by bacteria. Ampicillin has been used since 1961 in the treatment of bacterial infections.
When is it used?
Ampicillin is a broad-spectrum antibiotic, which means it is effective against many bacteria. Ampicillin is prescribed for various types of bacterial infections, including urinary infections, (bladder infection), middle ear infection, certain types of meningitis, and respiratory infections such as sinusitis (sinus infection) and pneumonia.
How to use Ampicillin
Ampicillin capsules should be taken on an empty stomach, 30 minutes to an hour prior to eating. Always swallow the tablet whole with some liquid. If you have forgotten to take your capsule, you may take the missed dose unless it is almost time for your next scheduled dose. Never take an extra capsule of Ampicillin to make up for the forgotten dose.
Ampicillin is available in packs containing 28 capsules of 250 mg or 500 mg. Unless otherwise prescribed by your doctor, the general recommended dose is:
- For bladder infection: one capsule three times a day
- For pneumonia: one capsule four times a day
The doctor may prescribe an alternative dosage for other conditions. Ampicillin in the above strength is not suitable for children, unless otherwise instructed by a doctor.
Ampicillin generally has few side effects, but in some cases it may cause:
- Gastrointestinal symptoms such as nausea, diarrhoea, stomach ache
- Muscle and rheumatic pain
- Note: Ampicillin can make birth control pills less effective, which may result in pregnancy. Additional contraceptive precautions should be taken while using Ampicillin.
See package leaflet for a complete list of possible contraindications, warnings and other side effects.
Ampicillin should only be used with your doctor’s approval if you are pregnant, planning to get pregnant or breastfeeding.
