Keflex is considered a cephalosporin antibiotic, which functions by stopping the growth of bacteria. Like any cephalosporin antibiotic, this medication can only be used to treat bacterial infections. It is ineffective against cold and flu viruses because they are viral infections.
Some conditions that Keflex is known to treat include infections caused by bacteria, including ear, skin, urinary tract, and upper respiratory infections. Keflex is available only by prescription. It is available in a generic formulation as well as under different brand names, including Bio-Cef and Panixine DisperDose.
Keflex may be prescribed in a capsule: 250 mg, 500 mg, and 750 mg. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage that you are prescribed.
If you are prescribed Keflex, be sure to complete the full course unless your doctor specifically tells you to stop.
If you don’t complete your prescription, the cephalosporin antibiotic may not fully treat your bacterial infection.
There are 5 FDA-approved uses for Keflex, but it may also be used off-label to treat other conditions. Your online medical professional may prescribe it for any of the following common reasons. It’s also possible that your health care provider may prescribe it for other reasons not listed here. Ask your online doctor or pharmacist if you have questions about why a medication is prescribed.
Infections that are caused by bacteria entering the respiratory tract
Middle ear infections that are caused by bacteria
Infections of the epidermis, dermis, or subcutaneous tissue
