Used to treat a variety of bacterial infections, including pneumonia, urinary tract infections, skin infections, and infections of the abdomen and blood. It is effective against both Gram-positive and Gram-negative bacteria, making it suitable for use in hospital settings where broad-spectrum coverage is needed. Often administered intravenously in severe infections, especially in patients with compromised immune systems. Commonly used when other antibiotics fail or when the causative bacteria are resistant to multiple drugs.
