Information for a friend
Dec 26, 2017

My friend today told me he stopped taking his HIV meds 12-13 months ago. I'm worried. I've read that missing a single dose or even a few days will cause the t cells to go back into full dying off,and making the drugs resistant. I have told him i think this is true. Please inform me and him please. Thank you.

Response from Dr. Young

Hello and thanks for posting.

Fortunately, you're mistaken. Neither a single missed dose, nor a prolonged treatment interruption results in viral drug resistance.

Current HIV medications certainly allow for less than perfect adherence. We must get past the Puritanical view (once popular) that suggests that people living with HIV must now be perfect in order to survive with medications. Indeed, human imperfection works with today's medications, allowing for adherence as low as 90% without a measurable difference in treatment failure or drug resistance.

Treatment interruptions are generally not recommended, but not for reasons of drug resistance, but rather, for increased health risks and loss of immune function. Nonetheless, we acknowledge that for a variety f reasons, interruptions do occur (i.e., pill fatigue, insurance gaps, supply stock outs). Prolonged treatment interruptions (provided that all medications are stopped simultaneously), similarly carry very low, or no risk of drug resistance.

I hope that's helpful. Do reach out to your friend and correct your misinformation, and perhaps encourage him to reconsider being back on medications.
