Cephalexin is a widely used antibiotic that belongs to the cephalosporin class. It is primarily used to treat bacterial infections and works by killing the bacteria or preventing its growth. Cephalexin comes in various forms, such as tablets, capsules, and liquid, and is available in different dosages. In this article, we will discuss the uses, side effects, dosage, interactions, and other important information about cephalexin.
Cephalexin is used to treat a wide range of bacterial infections, including respiratory infections, skin infections, urinary tract infections, and strep throat. It is also commonly used to treat other infections such as sinus infections, wound infections, ear infections, pneumonia, tooth infections, and bronchitis. Cephalexin (Keflex) is effective against a broad range of bacteria and is often prescribed as the first-line treatment for many infections.
The recommended dosage of cephalexin varies depending on the type and severity of the infection. For adults, the usual dosage of cephalexin is 250mg to 500mg taken four times a day, with or without food.
