Should Someone With a Penicillin Allergy Take Prezista?
I’m allergic to penicillin. Furthermore, I seem to have developed mutation K103 while on Sustiva. I’m currently taking Truvada and Sustiva. My doctor wants to remove the Sustiva and add Prezista (darunavir, TMC114). I have recently learned that Prezista is a sulfa drug, and is perhaps dangerous to someone with allergies to other sulfa drugs. Am I at risk? Response from Benjamin Young, M.D.
