Among more than three thousand American men who have sex with men, the reasons for stepping away from PrEP turn out to be as varied as the reasons for starting it. Some left because their lives shifted in ways that made the drug no longer necessary, while others were worn down by side effects, obstacles in the health system, or quieter fears about privacy and being treated differently. Reported in the journal AIDS and circulated by the European AIDS Treatment Group, the findings suggest that a single response to 'dropout' would miss much of the human story behind it.
Re-Engaging PrEP Users Starts With Understanding Why They Stopped, Study of 3,000+ MSM Finds
The reasons men leave PrEP are as varied as the reasons they begin it.
Mark
Why does it matter that people stop PrEP for different reasons?
Mimi
Because it changes what help looks like. In this survey of more than 3,000 men, about 35 percent stopped because their circumstances changed, mostly their sexual activity. That's not a failure.
Mark
So not everyone who stops should be brought back?
Mimi
Right. The experts say re-engagement should include confirming whether restarting PrEP is appropriate for that person.
Luke
Worth noting this is self-reported survey data. The reasons are what men said, and we don't have here how the categories were defined in detail.
Mark
What about the other groups?
Mimi
Twenty-four percent faced structural barriers, and 41 percent were in a clinical or multi-barrier group, often involving side effects.
Luke
The biggest group is the vaguest label. We know side effects were frequent in it, but not how often, or what the other barriers were.
Mark
And the privacy finding?
Mimi
Privacy and discrimination concerns doubled between 2018 and 2024, most often among young men.
Luke
Doubled from what to what? The source gives no baseline figures, so I'd hold the claim at "rose substantially" in direction only. And it doesn't say why.
Mimi
Fair. What's clear is the experts want individualized, multipronged approaches rather than one message for everyone.
Le Pouls
- A plain question put to over 3,000 men has uncovered a tangle of reasons, not one simple cause of people dropping out of prevention.
- Roughly a third of those who stopped did so because their circumstances changed, which means many may have made a sound decision that needs no correction.
- Nearly a quarter ran into structural barriers, while the largest group, 41 percent, faced overlapping clinical problems and side effects all at once.
- Concerns about privacy and discrimination have doubled since 2018, especially among young men, pressing public health workers to rethink how they reach them.
- Re-engagement efforts are being pulled toward individualized strategies rather than blanket campaigns, with programs now expected to ask each man why he left first.
Among more than three thousand American men who have sex with men, the reasons for stepping away from PrEP turn out to be as varied as the reasons for starting it.

More than 3,000 men who have sex with men, all respondents to the American Men's Internet Survey, were asked a simple question: why did you stop taking PrEP? Their answers, analyzed in research published in the journal AIDS, reveal a picture far less uniform than a single 'dropout' problem would suggest. The reasons men leave are as varied as the reasons they begin.
Some stop because their lives have changed, most often through a shift in sexual activity. Others meet obstacles, some personal and some built into the systems around them, that make staying on the drug hard. The researchers sorted respondents into three groups: 24 percent faced structural barriers, 35 percent had changed circumstances, and the largest group, 41 percent, faced overlapping clinical or multi-barrier problems, frequently involving side effects.
That distinction matters. A man whose sexual activity has changed may have made a reasonable choice, so re-engagement cannot mean pushing everyone back onto the drug. Each person needs a check on whether restarting is appropriate, and those facing barriers need help shaped to their particular situation.
One trend stands out. Concerns about privacy and discrimination doubled between 2018 and 2024, mostly among young men. The direction is clear, even if the underlying numbers are not broken down here. Programs hoping to bring people back should begin by asking why they left, and watch for whether privacy protections become a larger part of how PrEP is offered to younger men.
More than 3,000 men who have sex with men, all of them respondents to the American Men's Internet Survey, were asked a plain question: why did you stop taking PrEP? Their answers, analyzed in research published in the journal AIDS, point to a picture far less uniform than the idea of a single "dropout" problem would suggest.
The central finding is that the reasons men leave PrEP are as varied as the reasons they begin it. Some stop because their lives have changed. Others run into obstacles, some personal and some built into the systems around them, that make continuing difficult. The analysis, reported by TheBodyPro and circulated by the European AIDS Treatment Group, treats these as distinct situations rather than one phenomenon.
The researchers sorted respondents into three profiles. The smallest group, 24 percent, faced structural barriers to staying on PrEP. A larger group, 35 percent, had changed circumstances, most often a change in sexual activity. The biggest group, 41 percent, fell into a clinical or multi-barrier category, where several obstacles overlapped and side effects were frequently part of the story.
That split matters because it means that roughly a third of those who stopped may have done so for reasons that do not call for any intervention at all. A man whose sexual activity has changed may have made a reasonable decision. The experts quoted in the analysis say re-engagement therefore cannot be a blanket campaign to put everyone back on the drug. It has to include a check on whether restarting PrEP is actually appropriate for that person's situation.
For those facing barriers, the experts call for individualized, multipronged strategies. A person stopped by side effects needs something different from a person stopped by structural obstacles, and the largest group, with overlapping problems, may need several kinds of help at once.
One trend in the data stands out. Concerns about privacy and discrimination doubled between 2018 and 2024. These concerns were most often reported by young men. The source does not break down the underlying numbers here, but the direction is clear: among the younger respondents especially, worry about being exposed or treated differently has grown as a reason for stepping away from PrEP.
The practical implication is that programs hoping to bring people back should begin by asking why they left. The survey gives public health workers a rough map of the main answers, but the experts' conclusion is that each person's reason needs to be understood before any outreach can be effective. Watch for whether prevention programs begin tailoring their re-engagement work to these profiles, and whether privacy protections become a larger part of how PrEP is offered to younger men.
