How often can I miss a dose?

Hi, I have been on Sustiva/Truvada for 7 months and only missed 1 dose.
In your opinion how often could you safeley miss a dose? Not intending to purposely miss doses just a question really. Thanks!
Answer
I have a very traditional opinion and will have to say that you cannot miss doses safely.
The thing is that HIV does not mutate selectively, it does it randomly. Hense missing a dose is like a Russian roulette. During the period when the virus can replicate (as there is not enough medication to supress it in your body), it can mutate in such a way, that it becomes resistant to the medication, but it also can mutate in a way that it does not become resistant.
Hence every missed dose is a potential resistance provoker and it is more true with the non-nucleoside reverse transcriptase inhibitors (Sustiva and Viramune) than with the protease inhibitors.
At the same time, as I mentioned before, not every missed dose will by default lead to resistance, but, again, less is better.
Hi Pau,
As the answer above says, a very traditional opinion will say that you cannot miss doses safely.
However, accidents like this happen. And the risk of drug resistance can increase if missing doses happens often. So all is probably fine. But it’s a good idea to tell your doctor about this when you’re back home.
