What infections does cephalexin treat?
Cephalexin is an antibiotic in the cephalosporin class. It’s used to treat certain bacterial infections, particularly those involving the skin and soft tissue and infections that are caused by susceptible bacteria in areas like the respiratory tract and urinary tract (when prescribed for the specific diagnosis and suspected organism) [1].
What kinds of skin and soft-tissue infections is cephalexin used for?
Clinicians commonly use cephalexin for infections of the skin and soft tissues such as:
- Cellulitis
- Impetigo
- Infected wounds (depending on the cause and severity) [1]
Does cephalexin treat ear, throat, or other respiratory infections?
It may be prescribed for specific bacterial respiratory infections when they are expected to be susceptible to cephalexin, such as some cases of:
- Strep throat (pharyngitis/tonsillitis) in appropriate patients
- Certain ear infections (otitis media) [1]
Does cephalexin treat urinary tract infections (UTIs)?
Cephalexin may be used to treat uncomplicated UTIs or other urinary infections caused by susceptible bacteria, based on the patient’s symptoms, exam, local resistance patterns, and sometimes urine testing [1].
What does cephalexin not treat (important)?
Cephalexin does not work for viral infections such as the common cold or most cases of flu. It also won’t help if the infection is caused by bacteria that are resistant to cephalexin [1].
What should patients know before taking it?
Cephalexin should be taken exactly as prescribed. If symptoms don’t improve or worsen, or if a clinician suspects a resistant organism, the treatment plan may need to change. Patients should also let their prescriber know about any history of serious allergy to beta-lactam antibiotics (like penicillins or cephalosporins) before starting [1].
