Ceftriaxone is a broad-spectrum antibiotic that belongs to the class of drugs known as cephalosporins. It is commonly used to treat various bacterial infections, including those affecting the lungs, skin, and urinary tract. Ceftriaxone works by inhibiting the growth of bacteria, making it effective against both gram-positive and gram-negative organisms. This medication is typically administered through an injection, either into a muscle or intravenously. It is important to use Ceftriaxone as prescribed by a healthcare professional to ensure its effectiveness and to reduce the risk of antibiotic resistance. Common side effects may include allergic reactions, gastrointestinal disturbances, and changes in blood cell counts.
