Cephalexin is an antibiotic that belongs to the class of cephalosporins. This class of antibiotics is cell wall synthesis inhibitors. They stop the growth of bacteria in the body to treat the infections.

What does the research suggest?

Sensitivity to the sun includes photoallergy and phototoxicity. While Cephalexin is not associated with such effects, there are some other cephalosporins that are known to cause sun sensitivity (4).

Not every person using cephalosporins may experience sun sensitivity, It might vary among individuals. The variations in the effects of the same medication in different individuals may be attributed to certain other factors such as genetic predisposition.

Cephalexin has a significant list of side effects such as sinus infection but sun sensitivity is not a part of it.

Cephalexin might not be associated with sun sensitivity. However, if you experience any of the symptoms of sun sensitivity while taking Cephalexin, then you need to protect yourself from sunlight.  Here are a few tips that can help you protect yourself from the sun.

In my opinion, Cephalexin is a cephalosporin that does not cause sun sensitivity. There are no reported cases or any research evidence that might suggest otherwise. However, side effects of every medication differ among individuals and are not the same due to various individual factors acting on it. 

The same can be the case with Cephalexin. So, if you experience any sensitivity to sun while taking Cephalexin then you need to immediately contact your doctor so that they can provide you a proper treatment and make the necassary changes in your current treatment.
