Introduction HIV pre-exposure prophylaxis (PrEP) is a extremely efficient technique of stopping HIV transmission. Conventional PrEP entails taking a once-daily tablet, usually containing the antiretroviral medicine tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC), to cut back the chance of HIV an infection. Nonetheless, a more recent strategy to PrEP, referred to as event-based PrEP, has gained recognition lately. On this weblog put up, we are going to discover what event-based PrEP is, the way it works, and its benefits and downsides in comparison with conventional PrEP.
What’s event-based PrEP?
Occasion-based PrEP, also called “on-demand PrEP” or “intermittent PrEP,” entails taking PrEP medicine across the time of a possible HIV publicity, slightly than taking it day by day. The really useful dosing for event-based PrEP is 2 capsules of TDF/FTC, taken 2-24 hours earlier than anticipated sexual exercise, adopted by one tablet 24 hours later and one other tablet 48 hours later.
The rationale behind event-based PrEP is that it reduces the general variety of capsules that must be taken, which may be extra handy for some individuals, and probably reduces the general value of PrEP. Moreover, event-based PrEP could also be a extra engaging possibility for individuals who don’t interact in frequent or common sexual exercise.
How efficient is event-based PrEP?
Research have proven that event-based PrEP may be extremely efficient at stopping HIV transmission. The IPERGAY trial, a randomized managed trial performed in France and Canada, discovered that event-based PrEP diminished the chance of HIV an infection by 86% in comparison with a placebo. One other research, referred to as the ANRS-Prévenir research, performed in France, discovered that event-based PrEP was non-inferior to day by day PrEP when it comes to efficacy.
You will need to notice that the efficacy of event-based PrEP depends on adherence to the dosing routine. Within the IPERGAY trial, members got particular directions on when to take their medicine, and adherence was intently monitored. It’s unclear if event-based PrEP could be as efficient in a real-world setting the place adherence isn’t as strictly monitored.
Benefits of event-based PrEP:
Occasion-based PrEP affords a number of benefits over conventional day by day PrEP. For some individuals, taking a tablet day by day may be difficult, and event-based PrEP could also be a extra possible possibility. Moreover, event-based PrEP could also be more cost effective, as fewer capsules must be taken total. For individuals who don’t interact in frequent or common sexual exercise, event-based PrEP could also be a extra engaging possibility, because it doesn’t require day by day medicine.
Disadvantages of event-based PrEP:
There are some potential disadvantages to event-based PrEP. One of many major considerations is that adherence to the dosing routine could also be tougher than taking a day by day tablet. If the dosing routine isn’t adopted accurately, the effectiveness of event-based PrEP could also be diminished. Moreover, event-based PrEP will not be appropriate for everybody, as it’s primarily really useful for individuals participating in episodic or rare sexual exercise.
One other potential drawback is that event-based PrEP doesn’t shield in opposition to different sexually transmitted infections (STIs). It’s nonetheless vital to make use of condoms and get common STI testing, no matter whether or not you take PrEP.
Is event-based PrEP proper for me?
Whether or not event-based PrEP is the appropriate possibility for you will depend on your particular person circumstances. In case you interact in common sexual exercise, day by day PrEP could also be a extra applicable possibility. Nonetheless, should you interact in episodic or rare sexual exercise, event-based PrEP could also be a viable possibility for you.
