Injectable PrEP: The Complete Guide

Two shots a year instead of a daily pill. Yeztugo and Apretude offer game-changing alternatives — and both have patient assistance programs covering the full cost.

Injectable PrEP is the biggest advance in HIV prevention since the original approval of oral PrEP in 2012. Instead of remembering a daily pill, you get an injection every 2 or 6 months — and clinical trials showed extraordinary efficacy, with one trial recording zero HIV infections.

Two injectable PrEP medications are now FDA-approved. Both can be obtained at zero cost through manufacturer patient assistance programs. Here's everything you need to know.

Yeztugo (Lenacapavir) — Every 6 Months

Gilead Sciences · Approved June 2025

Yeztugo

lenacapavir — subcutaneous injection
6 mo
Between injections
100%
Efficacy in PURPOSE 1 trial
$0
Available through PAP

Yeztugo is the first twice-yearly injectable PrEP — a subcutaneous injection every 6 months after initial oral loading doses. It was approved by the FDA on June 18, 2025, based on the landmark PURPOSE clinical trial program.

The results were historic. The PURPOSE 1 trial in cisgender women recorded zero HIV infections — 100% risk reduction. The PURPOSE 2 trial in a diverse population (men who have sex with men, transgender people, non-binary individuals) showed only 2 infections — a 96% risk reduction. These are the strongest efficacy results ever seen in a PrEP trial.

Yeztugo Cost & Assistance

Yeztugo's list price is approximately $28,218 per year. However, most patients should pay nothing:

How Yeztugo Works

Yeztugo uses a novel mechanism — it's a capsid inhibitor that interferes with multiple stages of the HIV lifecycle. The dosing schedule starts with oral loading doses, followed by a subcutaneous injection at the start of month 1, then every 6 months thereafter. The injection is administered by a healthcare provider — it takes a few minutes and is given just under the skin (not into muscle).

Coming next: A once-yearly lenacapavir formulation is currently in Phase III trials, with results expected around 2028. This could further simplify PrEP to a single annual injection.

Apretude (Cabotegravir) — Every 2 Months

ViiV Healthcare · Approved December 2021

Apretude

cabotegravir — intramuscular injection
2 mo

More effective than daily oral in trials

Available through ViiV PAP

Apretude was the first injectable PrEP approved by the FDA (December 2021). It requires an intramuscular injection every 2 months after an initial loading phase of two injections one month apart. In clinical trials, it was 69% more effective than daily oral TDF/FTC at preventing HIV.

List price is approximately $4,038 per injection (~$24,000/year). It's covered under most commercial, Medicaid, and Medicare plans as a medical benefit, though insurers frequently require prior authorization.

Who Should Consider Injectable PrEP?

Injectable PrEP may be a great fit if you:

Injectable PrEP may be less ideal if you have needle anxiety, live far from an injection provider, or prefer the flexibility of stopping and starting that oral PrEP offers more easily.

Important note for trans women and people assigned female at birth: Descovy (oral) is not approved for people at risk through vaginal sex who were assigned female at birth. However, Yeztugo and Apretude (injectable) are approved for all adults at risk regardless of sex assigned at birth. This makes injectable PrEP particularly valuable for these populations.

How to Get Your First Injection

Step 1: Talk to a provider

You can discuss injectable PrEP with your regular doctor, an HIV specialist, or through a telehealth platform. MISTR is currently enrolling patients for Yeztugo. Your provider will assess your risk factors, run baseline labs (HIV test, kidney function, hepatitis B), and discuss which option is right for you.

Step 2: Apply for cost assistance

Before your first injection, get your cost coverage sorted. If you have private insurance, confirm with your plan that injectable PrEP is covered. Apply for the Gilead copay card (Yeztugo) or ViiV copay card (Apretude) to cover any out-of-pocket costs. If you're uninsured, apply for the manufacturer PAP.

Step 3: Get your loading doses

Both medications start with a loading phase. Yeztugo begins with oral loading doses before the first injection. Apretude starts with two injections one month apart, then switches to every 2 months.

Step 4: Maintain your schedule

Yeztugo: return for injection every 6 months. Apretude: every 2 months. Your provider will schedule these visits and continue monitoring labs. Missing or delaying injections can reduce protection — set reminders and keep your appointments.

Injectable PrEP FAQ

Does the injection hurt?

Most people report mild discomfort. Apretude (intramuscular, into the gluteal muscle) tends to cause more injection site reactions — pain, swelling, or hardness at the injection site. These are common but temporary, usually resolving within a week. Yeztugo (subcutaneous, under the skin) is generally reported as less painful.

Can I switch from oral PrEP to injectable?

Yes. Discuss the transition with your provider. They'll typically run updated labs and start you on the injectable loading schedule. There should be no gap in protection if the transition is managed properly.

What if I miss an injection appointment?

Contact your provider as soon as possible to reschedule. Delaying injections can reduce protection. Your provider may recommend bridging with oral PrEP if there's a significant delay. This is more of a concern with Apretude (every 2 months) than Yeztugo (every 6 months).

Is injectable PrEP covered by insurance?

Under the ACA preventive services mandate, most private insurance plans must cover all FDA-approved PrEP at $0 cost-sharing, including injectables. However, some insurers may require prior authorization or step therapy (trying oral PrEP first). Medicaid and Medicare also generally cover it, though details vary by state and plan.

Can injectable PrEP be manufactured cheaply?

Yes. Yeztugo (lenacapavir) can be manufactured for as little as $26–$40 per year. The Gates Foundation and Unitaid have arranged generic production at $40/year for 120 low- and middle-income countries starting in 2027. The US list price of ~$28,218/year reflects the current pharmaceutical pricing structure, not manufacturing costs.
