Atripla & Viagra

Question

Hello Dr. Holodniy

My libido seems to be decreasing since I start taking atripla. Can I take viagra when I take atripla? Does atripla also cause pins & needles on the body? Thank you.

Answer

Efavirenz in Atripla could reduce blood levels of Viagra (Sildenafil). You should discuss any use of these two drugs together with your doctor first. Pins and needles would be an usual reaction with Atripla.
