Question

What is the interaction between Biktarvy and Iron supplements?

Hi. I’ve recently started Biktarvy and I’ve been told I’m anaemic and been prescribed an iron supplement to take twice a day. The GP told me there was an interaction but wasn’t sure what it was so was hoping you could tell me the best time to take the iron supplements in relation to the Biktarvy? I take that at about 8am.
Many thanks.

Answer

Hi, how are you doing?

There is an interaction. If you take them together without food, Iron can reduce how much Biktarvy is absorbed by the body. You can avoid this by taking them together when you eat e.g., have breakfast at the same time of Biktarvy and Iron.

If this is not suitable you can avoid the interaction by taking Iron at the opposite end of the day. As you take Biktarvy in the morning, you can avoid the interaction by taking Iron in the evening instead.

    Hi Freya, Iron is best absorbed on an empty stomach. Though it can cause a bit of problems with your gut if you do this. The best time would be to take them a little after your meal. This helps avoid any problems with your stomach.

    Thanks so much for your response..I have two iron tablets to take so it sounds like it would be best for me to take two tablets with my evening meal?

    Thank you
