I was put on a 10 day course of cephalexin 500 mg. capsule therapy post-operatively. About the 6th day I started to develop a rash, however did not attribute it to the medication until I noticed that the rash started to spread with each subsequent dosing, and the itching intensified for about 2-3 hours after I took each dose. It started and has been evident primarily in the torso, however I did have a few patches on areas of both of my upper thighs. I have just stopped taking it, as it is the 9th post-op day and will see if it subsides and how long. It did not dawn on me that this might be attributed to the medication, being summer and having mosquitoes around. Will see how long it takes to get back to normal.
