What Is Keflex Prescribed For?

Keflex^® (cephalexin) is a common antibiotic prescribed for a number of infections. Specifically, it is approved for treating bacterial infections and preventing heart valve infections (bacterial endocarditis).

Bacterial Infections

Keflex is most commonly used to treat infections caused by bacteria. Some of these types of infections include:

Respiratory tract infection (pneumonia, bronchitis, strep throat, or tonsillitis)
Bone infection (osteomyelitis)
Middle ear infection (otitis media)
Sinus infection (sinusitis)
Urinary tract infection (UTI).

Bacterial Endocarditis

Endocarditis occurs when the inner lining of the heart (the endocardium) develops inflammation, usually from an infection. Bacterial endocarditis occurs when bacteria are responsible for causing the inflammation. It can occur after a number of procedures, such as dental procedures. Keflex may help prevent this by curbing the growth of bacteria and reducing inflammation.
