Ampicillin is a broad-spectrum penicillin antibiotic used to treat bacterial infections.
Dosage:
Adult Dosage: The usual adult dose for ampicillin is 250 to 500 mg every 6 hours, or 1 to 2 grams every 4 to 6 hours, depending on the severity of the infection.
Children Dosage: The pediatric dosage for ampicillin depends on the child's weight, with a typical dose of 25 to 50 mg/kg/day divided into four doses.
Dosage in Liver and Renal Impairment:
Liver Impairment: Ampicillin dosage may need to be adjusted in patients with severe liver impairment.
Renal Impairment: In patients with renal impairment, the dose of ampicillin should be adjusted based on the degree of renal dysfunction.
Pregnancy and Lactation:
Pregnancy: Ampicillin is generally considered safe to use during pregnancy, but it should be used only if clearly needed.
Lactation: Ampicillin is excreted in breast milk, so caution should be exercised when prescribing to nursing mothers.
Risk Factors:
Hypersensitivity: Patients with a history of hypersensitivity to penicillins should avoid taking ampicillin.
Diarrhea: Ampicillin can cause diarrhea, and patients with a history of diarrhea should use caution when taking this medication.
Indications:
Respiratory tract infections
Urinary tract infections
Skin and soft tissue infections
Gastrointestinal infections

Advice to Patients:
Take ampicillin as prescribed by your doctor, even if you feel better before finishing the entire course of medication.
Inform your doctor if you experience any adverse effects, such as skin rash or diarrhea.
Avoid taking antacids or iron supplements within two hours of taking ampicillin, as they can decrease its effectiveness.
Administration:
Ampicillin is available in oral and injectable forms and should be taken as directed by your healthcare provider.
Pharmacokinetics:
Ampicillin is rapidly absorbed after oral administration, with peak serum concentrations achieved within 1 to 2 hours.
The drug is widely distributed throughout the body, and therapeutic concentrations are achieved in most tissues and fluids.
Ampicillin is primarily excreted unchanged in the urine, and its elimination half-life is approximately 1 hour.
Interactions:
Ampicillin may interact with other medications, such as probenecid, that affect renal function or with other antibiotics that have a similar mechanism of action.
Adverse Effects:
Diarrhea
Nausea and vomiting
Rash
