What Is Lenacapavir & How It Works
Lenacapavir, approved by the FDA in 2024 under the brand name Yeztugo, is the first capsid inhibitor for HIV prevention. Unlike oral PrEP medications like Truvada or Descovy that must be taken daily, lenacapavir is injected just twice a year. It works by disrupting the protein shell (capsid) of the HIV virus, preventing it from replicating.
This long-acting treatment is ideal for people who struggle with daily medication adherence. It represents a shift toward simplified, more discreet HIV prevention methods that fit more naturally into people’s lives.
Lenacapavir vs Traditional PrEP
Traditional PrEP has saved countless lives, but its effectiveness depends on consistent daily use. That’s where lenacapavir shines. In clinical trials, it showed similar efficacy to oral PrEP but with the added benefit of requiring only biannual dosing.
Here’s how they compare:
- Daily PrEP (e.g. Truvada, Descovy): High effectiveness when taken consistently. Requires frequent refills and monitoring.
- Lenacapavir: Long-acting injectable, administered every 6 months. Increases adherence and reduces stigma associated with pill use.
For individuals with unstable housing, busy lifestyles, or healthcare access barriers, the simplicity of two injections a year can be life-changing.
Who Can Benefit from Lenacapavir?
Lenacapavir is particularly beneficial for:
- Young people at higher risk of HIV who struggle with daily PrEP
- Sex workers and mobile populations
- Transgender individuals facing systemic healthcare barriers
- People with substance use disorders
It’s also an excellent option for people living in areas with limited healthcare access. The reduced dosing schedule minimizes visits to clinics and simplifies logistics, especially in rural and underserved areas.
Access, Cost & Global Equity
While lenacapavir marks a leap forward scientifically, questions about access and affordability remain. The manufacturer, Gilead Sciences, announced in 2025 that the drug will be offered for as little as $40 per year in over 120 low-income countries, thanks to licensing deals with global health organizations (source).
However, scaling up production and distribution will require major investments in training, infrastructure, and community education. Without these, the benefits of lenacapavir could be delayed in the very regions where it’s needed most. Advocacy organizations and health systems will play a crucial role in bridging these gaps. Seek expert advice if you’re unsure which prevention option is best for you.
Future of HIV Prevention
Lenacapavir is just the beginning. Researchers are exploring even longer-acting formulations, implantable options, and injectable combinations that also treat other STIs. A vaccine remains elusive, but strategies like lenacapavir are making prevention more accessible and realistic for millions.
For organizations, digital campaigns and educational outreach through digital health advertising platforms can raise awareness and accelerate adoption. Public health efforts must evolve alongside science to keep momentum strong in the fight against HIV.
