Question

Can I take Viagra with efavirenz and Truvada?

Hello

I currently take Sustiva (efavirenz) and Truvada daily. Can I use Viagra with this medication?

Many thanks

Answer

Thank you for your question.

There is a potential interaction between Viagra (sildenafil) and efavirenz (Sustiva). You should speak to your doctor if you want to take Viagra as you may require close monitoring, an alteration of drug dosage or a change in the time you take each drug.

    Hi,

    I was recently prescribed Levitra by my GP. I’m also on Atripla my GP I did ask him was it safe/ any interactions and he said it was fine. I looked online and it seems that it may result in lower levels of Levitra in the blood (requiring a higher dosage) but no detrimental impacts with Atripla – is that correct? Would I be better asking for Cialis?

    Thanks
