A New Year, A New Way to Take PrEP?
I recently packed up my life into a truck and moved across the country. I was ecstatic to be employed in a field where jobs are offensively scarce, but was sad to be putting even more distance between me and my boyfriend. We’d been a two-hour drive apart until then. Now it would take four hours on a plane to reunite.
I started taking PrEP daily before I ever met Tim, my boyfriend of just over a year. For two years, I’ve taken those little blue pills just about every day—save maybe a few misses here and there. My kidneys are in fine form. I take vitamin D and calcium supplements as a precaution against bone density loss. And side effects? What side effects?
By all accounts, me and PrEP make a great team.
But perhaps because of the stress of the move and a new job, my libido has waned. I’m in a new city with no regular tricks to rely on. And living in a neighborhood where most of the guys eager to fuck me within a 20-minute radius seem to be closeted married men in their 40s (nothing against them; it’s just not my scene). On top of that, I’ve got good dick waiting for me at home. I’m not going to hook up with just any schmuck. My standards have, unexpectedly, taken a turn for higher ground (maybe too high!).
A year ago, I was fucking a new guy every five days or so. Since I moved out west in August, though, I’ve had sex with exactly three people. And one of those doesn’t really count because I kicked him out of bed for being such a sloppy, frog-mouthed kisser. Yuck.
Of course, another of those three is my wonderful boyfriend. When we’re together—about a week out of every month—we have beautiful sex and we don’t use condoms. He’s undetectable. I’m on PrEP. We’re basically the future.
As we come to the beginning of a new year, and reflect on days gone by, I have to start wondering: Should I keep taking those little blue pills every day? There are lots of reasons to think twice. Along with the number of men in my bed, my risk for joining the poz club has gone way, way down. And those pills ain’t cheap: I’m gulping down at least $30 every night before bed. I may not be paying for it, but somebody is. And although I’m not experiencing any side effects now, there’s always the concern that somewhere down the line that might change.
On the other hand, I am hoping to have at least some rando-sex. Perhaps even with closeted married men, if I must. And although the risk with me and the boyfriend is astronomically low, I know PrEP makes us both feel a lot more comfortable breeding each other silly.
Maybe there’s a middle ground, though. We’re in the early days of PrEP where taking a pill a day is the only FDA-approved strategy. But there are other PrEP strategies on the horizon. They’re testing out whether we can develop an injectable PrEP that your doctor could administer every three months or so. There’s also a fair amount of chatter around “intermittent PrEP” or “PrEP on demand.” Instead of taking a pill every day, the idea is that you might only have to take it when you need it. Scientists want to find out if taking two pills 24 hours before sex, a pill every day while you’re sexually active and a pill for two days after your last fuck prevents HIV infection. The handy diagram below illustrates the intermittent PrEP dosage being tested by French Canadian scientists in a study known as “IPERGAY.”
If you keep your nose in the PrEP science world, you might have heard that IPERGAY scientists announced in October that they were shutting down the study’s placebo arm because the initial results clearly showed that intermittent PrEP worked. With such clear-cut evidence to demonstrate effectiveness in hand, it was unethical to keep giving some people in the trial a placebo.
But although the scientists behind IPERGAY said intermittent worked, the real pickle is that they didn’t say precisely how well it worked. The study’s lead researcher let slip to the media a figure of “80%,” but the fact is we don’t really know. We will have firm figures soon, when they are announced at CROI (a big, annual HIV conference) in late February.
Looking toward the new year, I asked my doctor—a nationally renowned expert on PrEP—what he made of intermittent PrEP. He, of course, cautioned that we need to wait to know more, but he raised some interesting concerns. He noted that the IPERGAY data presented at AIDS 2014 showed that people in the study were taking, on average, about 15 pills a month. 15. Pills. A. Month. Some simple math reveals that this is the equivalent of taking PrEP every other day. Not so intermittent, eh?
Potentially more concerning is the 80% effectiveness figure casually cited by IPERGAY’s lead researcher. If it pans out, this would be a comparatively low figure for taking PrEP roughly every other day. Data from the iPrEx study showed that PrEP was 96% effective when it was taken only four times a week. A big question on many people’s minds is why isn’t IPERGAY’s 80% figure more similar to what iPrEx found? I think the answer lies in the complexity and unpredictability of our sexual lives. For PrEP to work—intermittent or daily—you need to have the drug in your body as soon as you are exposed to the virus. If you only start taking the drug after you have sex, that’s not PrEP at all—it’s what we call “post-exposure prophylaxis” or PEP. It can help protect you as well, but it’s not likely as effective as PrEP.
Of course, in order to have the drug in your body, you’ve got to plan ahead. In the IPERGAY trial, this meant taking two Truvada pills two to 24 hours before sex. Yet, part of the great joy of sex for many people it’s the very fact that it’s spontaneous, unplanned, and surprising. We can’t always predict when luck will strike. If you’re taking PrEP every day, then this isn’t much of an issue. But if you only take PrEP a few hours before sex, you’ve got to know when you’re getting lucky ahead of time.
In my sex life, there are some variables I can predict. I fly east once a month to see my partner. I can just about schedule our sex life. That’s one of the big bummers about being so far away: Being spontaneous is just about impossible. Outside of the relationship, however, predicting when I’ll manage to find a guy online that I think is fuckable (and who is similarly into me) and that is available at the same time I am is not exactly easy where I live now. Unfortunately, it’s the tricks who are most likely to infect me—not my boyfriend. In other words, the sex for which I most need to be “PrEPared” is also the sex that is most unpredictable.
2014 was big year for PrEP. As we start 2015, we look towards the future of PrEP and all eyes will be on CROI in February to see how the data finally shake out. At least where I sit, if the final data show that taking intermittent PrEP an average of 15 times a month is only 80% effective, I can’t see how complicating your PrEP regimen by having to predict when you’re going to hook up would make much sense for anyone currently taking it daily. I’d rather continue my daily regimen, rather than risk screwing it all up by not starting it far enough in advance—much less saying no to potentially great sex because I hadn’t taken my pills yet!
Perhaps intermittent PrEP will still make sense for some people who cannot or will not take it daily—or for people in very particular situations (e.g. where the bulk of their sex is concentrated in predictable time periods, such as business trips)—and maybe having an alternative to a daily dose will get more people on PrEP. That remains to be seen.
