Ampicillin is a penicillin-type antibiotic that treats bacterial infections. It works by stopping bacterial growth, commonly prescribed for respiratory, urinary, and gastrointestinal infections. Effective against both gram-positive and gram-negative bacteria, it's a versatile treatment option.
This antibiotic inhibits bacterial cell wall synthesis, causing the bacteria to rupture and die. It targets a wide range of infections, including E. coli, Salmonella, and Streptococcus. Doctors often prescribe it for its broad-spectrum efficacy.
Ampicillin is available as oral capsules, tablets, and injectable solutions. Dosage depends on infection severity and patient age. Always follow medical advice for proper administration.
Mild side effects include nausea, diarrhea, or skin rash. Severe reactions like allergic responses require immediate medical attention. Consult a doctor if symptoms persist.
Overuse can lead to antibiotic resistance. Take only as prescribed and complete the full course. Never share antibiotics or use leftover doses.
Store at room temperature, away from moisture. Keep out of reach of children. Discard expired medication safely.
Compared to amoxicillin, ampicillin has a broader spectrum but lower oral absorption. It’s often used for severe infections requiring IV administration.
