Truvada is a brand-name prescription medication manufactured by Gilead Sciences, Inc. It is a fixed-dose combination tablet containing two nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs): emtricitabine (FTC, 200 mg) and tenofovir disoproxil fumarate (TDF, 300 mg). Both components block the reverse transcriptase enzyme that HIV needs to copy itself, preventing viral replication.
The FDA first approved Truvada for HIV-1 treatment on August 2, 2004. In July 2012, Truvada became the first FDA-approved oral medication for HIV pre-exposure prophylaxis (PrEP), a prevention strategy for HIV-negative individuals at substantial risk of acquiring HIV. Generic emtricitabine/tenofovir disoproxil fumarate became available in the U.S. in 2020 and is now supplied by multiple manufacturers, making it among the most affordable antiretrovirals available.
Truvada is FDA-approved for: (1) HIV-1 treatment in adults and pediatric patients weighing at least 17 kg, used in combination with other antiretroviral medications; and (2) HIV pre-exposure prophylaxis (PrEP) in at-risk adults and adolescents weighing at least 35 kg. When taken consistently as PrEP, Truvada reduces the risk of sexually acquired HIV infection by approximately 99%.

Truvada works by blocking HIV's ability to replicate inside human cells. HIV uses an enzyme called reverse transcriptase to copy its genetic material (RNA) into DNA inside the host cell — a critical step the virus needs to integrate itself and produce new copies. Both components of Truvada are NRTIs: they mimic natural DNA building blocks (nucleosides/nucleotides) and get incorporated into the viral DNA chain, but once inserted they terminate chain elongation, halting the copying process.
Emtricitabine (FTC) is a synthetic analogue of cytidine. Tenofovir disoproxil fumarate (TDF) is a prodrug that converts to the active nucleotide tenofovir inside cells. Using two NRTIs together creates dual-blockade of the reverse transcriptase enzyme, which is more effective and more resistant to viral escape than using one NRTI alone.
For HIV treatment, Truvada must be combined with at least one additional antiretroviral (typically an integrase strand transfer inhibitor) to form a complete suppressive regimen. For PrEP, daily Truvada alone maintains sufficient drug concentrations in blood and mucosal tissues to block infection if HIV exposure occurs. Both FTC and TDF are primarily renally eliminated, with FTC reaching peak plasma concentration 1–2 hours post-dose and TDF within 1 hour.

As of 2026, Truvada and its generic equivalent (emtricitabine/tenofovir disoproxil fumarate) are not listed on the FDA Drug Shortage Database. Multiple generic manufacturers supply the U.S. market, and national supply is stable. However, because brand-name Truvada's market share has declined significantly — with only about 4,400 brand prescriptions per quarter in Q1 2026 (IQVIA) compared to its peak volumes — some retail pharmacies no longer maintain standing inventory of the brand product.
Patients may encounter local stockouts due to: a pharmacy carrying only one generic manufacturer's version that is temporarily backordered; insurance formulary requiring a specific formulation; or smaller pharmacies not stocking HIV medications routinely. Large chain pharmacies (CVS, Walgreens, Walmart) and specialty HIV pharmacies typically maintain the most consistent stock of generic emtricitabine/TDF.
If you're having trouble finding Truvada in stock, medfinder calls pharmacies near you to check which ones have your specific medication and can fill your prescription, then sends you the results by text — so you don't have to spend time on hold calling pharmacies yourself.
Truvada is not a controlled substance, and there are no DEA scheduling requirements for prescribers. Any licensed healthcare provider who is authorized to prescribe medications in their state can prescribe Truvada — for both HIV treatment and PrEP. No HIV specialization is required for PrEP prescribing.
Providers who commonly prescribe Truvada include:
Primary care physicians (family medicine, internal medicine)
Infectious disease specialists and HIV physicians
Nurse practitioners (NPs) and physician assistants (PAs)
OB/GYNs (increasingly for female PrEP patients)
Pharmacists (in Arkansas, California, Colorado, Illinois, Maine, Nevada, Oregon, Utah, and Virginia)
Telehealth is widely used for PrEP — approximately 19% of all U.S. PrEP prescriptions were filled through telehealth services in 2024 (JAMA), up from just 2% in 2020. Multiple telehealth platforms can provide a PrEP consultation, order required lab work, and send a Truvada prescription to your pharmacy or ship directly to your home.
No. Truvada (emtricitabine/tenofovir disoproxil fumarate) is not a controlled substance and is not scheduled by the U.S. Drug Enforcement Administration (DEA). It does not have abuse or dependence potential, and there are no special federal prescription requirements based on controlled substance scheduling.
As a non-scheduled medication, Truvada can be prescribed by any licensed healthcare provider, including via telehealth. There are no federal restrictions on refills based on controlled substance law, no DEA registration requirements for prescribers, and no limits on prescription quantities imposed by scheduling rules. Patients can generally receive 90-day supplies and use mail-order pharmacy services without restriction.
Most patients — especially HIV-negative individuals taking Truvada for PrEP — tolerate Truvada well. Common side effects include:
Nausea (often improves with food or over time)
Headache
Diarrhea and abdominal pain
Fatigue and dizziness
Serious side effects (less common, more important to monitor):
Kidney damage (renal impairment, acute renal failure, Fanconi syndrome) — monitor creatinine/CrCl
Bone mineral density loss (osteopenia, osteoporosis with long-term use — reversible upon stopping in PrEP users)
Lactic acidosis (rare but potentially life-threatening; symptoms include severe abdominal pain, weakness, breathing difficulty)
Hepatitis B worsening upon discontinuation (FDA boxed warning — never stop abruptly if you have hepatitis B)
Immune reconstitution syndrome (in HIV treatment patients — inflammatory response to recovering immunity)

Didanosine
majorTDF significantly increases didanosine exposure; dose reduction required to avoid pancreatitis, neuropathy, and lactic acidosis. Combination generally avoided.
Other FTC/TDF-containing antiretrovirals
majorNever co-prescribe with Biktarvy, Genvoya, Stribild, Complera, Descovy, Odefsey, Symtuza, Atripla, or Viread — double dosing causes increased toxicity.
NSAIDs (ibuprofen, naproxen at high doses)
majorConcurrent high-dose NSAID use increases risk of acute renal failure in patients on TDF, particularly with existing renal risk factors.
Atazanavir
moderateCoadministration decreases atazanavir concentrations; must boost with ritonavir when co-used.
Ledipasvir/sofosbuvir (Harvoni) and Epclusa
moderateHCV antivirals can increase tenofovir exposure, raising risk of TDF-related kidney and bone toxicity. Monitor renal function closely.
Darunavir/ritonavir, lopinavir/ritonavir
moderateBoosted HIV protease inhibitors may increase tenofovir plasma levels; increased renal monitoring warranted.
Truvada has been a cornerstone of HIV medicine for over two decades. As a treatment medication, it provides a reliable, once-daily NRTI backbone for millions of people living with HIV. As a PrEP medication, it was the first oral option approved for HIV prevention and remains highly effective — reducing the risk of sexually acquired HIV by approximately 99% when taken consistently. With robust generic availability since 2020 and cash prices as low as $21–$30/month with discount programs, it is among the most affordable antiretroviral options available.
While Truvada is not in an FDA shortage in 2026, individual pharmacies can still be out of stock. This is a logistics challenge, not a supply crisis. Patients who are persistent and know their options — including generic substitution, specialty HIV pharmacies, and mail-order services — can almost always find their medication filled.
If you're struggling to find Truvada near you, medfinder can help — we call pharmacies on your behalf and send you the results, so you can stop spending time on hold and focus on what matters: staying on your medication and protecting your health.
