|Atripla causing skin sensitivity to sunlight?
Apr 14, 2010
Hello there, I have been on Atripla now since last November, and had no problems with the drug until recently. Just in the last couple weeks the weather has gotten nice (if not somewhat hot) and I have spent alot more time outdoors as I usually do during warm months. I have never had any issues being outdoors before, but now all of the sudden I am getting a poison ivy like rash on my arms and neck where my skin was exposed to sun. It is only where my skin was exposed to sun. Where the sun exposure stops, the rash stops. It look similar to poison ivy, but smaller bumps, and is pretty itchy at times. The bumps occasionally will leak clear liquid if broken. They are fairly small bumps, but lots of them. Is this, or could this be a reaction to sunlight caused by one of the components of Atripla? I have never had any issues with sensitivity or allergic reactions to any medications, nor sunlight before. Thank you very much for any advice.

I have heard of several patients (and seen one) who developed sun sensitivity while on Atripla. It remains unclear to me if the efavirenz or the FTC would be be most likely involved component (I would favor the FTC). Other drugs such as sulfa antibiotics can contribute to sun sensitivity (also drugs like ibuprofen or tetracycline, or other illnesses such as lupus). If Atripla seems a likely cause then discussion about switching meds around on a trial basis may be warranted. If any reader knows of a reference or has personal experience please post. KH
