Amoxicillin is widely used as an antibiotic to treat various bacterial infections. It is effective against respiratory tract infections, such as pneumonia and bronchitis, as well as ear, nose, and throat infections like sinusitis and otitis media. It is also prescribed for urinary tract infections, skin infections, and certain gastrointestinal infections caused by Helicobacter pylori, often in combination with other medications. Additionally, it is used in dental procedures to prevent infections and in some cases to treat Lyme disease. Its broad-spectrum activity makes it a common choice for both adults and children.
