What is Cephalexin?

Cephalexin is a cephalosporin antibiotic. It works by stopping the growth of bacteria causing infections. It's effective against a wide range of bacteria, but it's crucial to remember it only works against bacterial infections, not viral ones (like the common cold or flu). A doctor will determine if Cephalexin is the right treatment for your specific infection.

Why 500mg Four Times a Day?

The dosage of 500mg four times a day is determined by your doctor based on the severity and type of infection. This frequent dosing helps maintain a consistent level of the antibiotic in your bloodstream, maximizing its effectiveness in fighting the infection. The specific dosage and duration are personalized to your needs.

Like all medications, Cephalexin can cause side effects. These vary in severity and frequency. Common side effects include:
