Ampicillin is a widely used antibiotic that belongs to the penicillin group of drugs. It is effective against various bacterial infections and is commonly prescribed for conditions such as respiratory infections, urinary tract infections, and gastrointestinal infections. Proper dosage is crucial for the effectiveness of the treatment while minimizing the risk of side effects and antibiotic resistance.
