Genvoya® for HIV-1: Single-Tablet Regimen, Uses, and Savings

What Genvoya® Is and How It Works

Genvoya® is a complete, once-daily HIV-1 treatment in one tablet. It combines elvitegravir (an integrase inhibitor), cobicistat (a pharmacokinetic booster), emtricitabine, and tenofovir alafenamide (both nucleoside reverse transcriptase inhibitors). This fixed-dose combination treats HIV-1 infection in adults and in adolescents who meet weight criteria. Many people compare Genvoya cost and access, including buying Genvoya without insurance, to manage long-term therapy.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba; prescriptions are reviewed by licensed pharmacists before dispensing.

Elvitegravir blocks the HIV integrase enzyme. This prevents viral DNA from joining human DNA. Emtricitabine and tenofovir alafenamide inhibit reverse transcriptase, stopping viral replication. Cobicistat slows the breakdown of elvitegravir, keeping levels steady. The result is strong viral suppression when taken as prescribed. Genvoya is taken by mouth once daily with food. It is not designed to be taken without food because a meal improves absorption.

We partner with licensed, vetted international pharmacies to offer authentic brand medications, wide selection, and competitive pricing.

Dosage and Usage

• Standard dose: one tablet by mouth once daily with food.
• Do not take Genvoya without food. A meal or snack helps achieve proper levels.
• Swallow the tablet whole. Do not crush, split, or chew.
• Missed dose: if remembered within about 18 hours, take with food as soon as possible. If it is close to the next dose, skip the missed dose and resume the regular schedule.
• Vomiting: if vomiting occurs within 1 hour of dosing, another tablet may be taken with food. If more than 1 hour has passed, do not take an extra dose.
• Antacids containing aluminum or magnesium: separate Genvoya by at least 2 hours before or after.
• Calcium or iron supplements and multivitamins: take with food at the same time, or separate by several hours if taken on an empty stomach.
• Acid reducers (H2 blockers, proton pump inhibitors): generally allowed with food at usual doses.
• Contraindicated or not recommended with strong enzyme inducers such as rifampin, carbamazepine, phenobarbital, phenytoin, and St. John’s wort.
• Avoid coadministration with simvastatin, lovastatin, certain sedatives (e.g., triazolam, oral midazolam), ergot derivatives, lurasidone, and pimozide.
• Discuss all prescription drugs, OTC medicines, and supplements due to cobicistat-related CYP3A interactions.

• Store at 15–30 °C (59–86 °F) in the original bottle with the desiccant. Keep the cap tightly closed.
• Protect from moisture. Do not store in bathrooms.
• For travel, keep tablets in the original container in your carry-on. Avoid extreme heat, direct sun, and freezing.
• If using a pill organizer, carry the labeled pharmacy bottle as backup when crossing borders.
• Do not remove the desiccant from the bottle.

Benefits and Savings

Genvoya offers convenient once-daily dosing and a complete regimen in one pill. It provides potent viral suppression and CD4 count gains in treatment-naive patients and those switching from other regimens without resistance. Tenofovir alafenamide delivers lower plasma tenofovir exposure than older TDF-based regimens, which supports improved renal and bone safety profiles in many patients.

The booster cobicistat allows for a small tablet and steady drug levels, and clinical trials show high rates of virologic suppression through 48 weeks and beyond. Genvoya must be taken with food, which suits many daily routines. Patients switching from certain regimens often report improved tolerability, fewer pills, and stable viral control. For cost-sensitive patients, ordering Genvoya without insurance from Canada can reduce out-of-pocket expenses.

Typical savings are 60–80% versus many US retail prices. Multi-month supplies can lower average monthly costs, and you can set simple reorder reminders so you do not run short. For promotions, see our genvoya coupon page for current offers.

Side Effects and Safety

• Common effects: nausea, diarrhea, headache, fatigue, dizziness, and insomnia.
• Digestive changes, abdominal pain, or decreased appetite.
• Skin rash or itching; rare cases of discoloration.
• Abnormal dreams or mood changes.
• Elevated creatinine due to cobicistat (tubular secretion effect) without true kidney injury in many cases.
• Back pain or joint pain.
• Weight changes, including gain or loss, may occur over time.
• Hair loss is uncommon; most cases are mild and reversible.

Serious risks are uncommon but include lactic acidosis and severe hepatomegaly with steatosis (NRTI class), acute hepatitis B flare after stopping the drug in HBV coinfection, significant renal impairment including proximal tubulopathy, and drug-drug interactions from CYP3A inhibition. Immune reconstitution syndrome can occur when viral load drops and the immune system recovers. Review all medicines and supplements to avoid contraindicated combinations.

Onset Time

Viral load often begins to decline within 2–4 weeks of starting Genvoya, with most patients achieving marked suppression by 8–24 weeks when doses are not missed. CD4 counts typically rise over several months. Gastrointestinal side effects often improve after the first few weeks. Any weight change, hair or skin effects, and lipid shifts may evolve over months and should be monitored during routine follow-up.

Compare With Alternatives

Biktarvy (bictegravir/emtricitabine/tenofovir alafenamide) is a once-daily, food-flexible option that does not require a booster. It has fewer CYP3A interactions and is commonly chosen for simplicity. Some patients still do well on Genvoya, especially when the food requirement fits their schedule.

Stribild® contains elvitegravir, cobicistat, emtricitabine, and tenofovir disoproxil fumarate (TDF). It is effective but has higher systemic tenofovir exposure, which can increase renal and bone risks compared with TAF-based Genvoya.

Boosted protease inhibitor regimens, such as darunavir with Norvir® (ritonavir), are options when resistance, tolerability, or prior therapy limits integrase-based regimens. They may require more pills and carry more interactions.

Combination Therapy

• Genvoya is a complete antiretroviral regimen. Do not combine with other HIV medicines for treatment unless directed by a specialist.
• Opportunistic infection prophylaxis (e.g., TMP-SMX) may be used when indicated. Check for interactions.
• Hepatitis C direct-acting antivirals can interact; some combinations are not recommended. Confirm compatibility.
• Antacids and mineral supplements require spacing as noted to protect elvitegravir levels.
• Hormonal contraceptives may interact. Consider a barrier method or alternative per clinician guidance.

Patient Suitability and Cost-Saving Tips

Genvoya is used for adults and eligible adolescents with HIV-1 who need a complete, once-daily regimen and have no known resistance to its components. It may suit those switching from older TDF-based regimens to reduce renal and bone risks. It is not recommended if creatinine clearance is below 30 mL/min or in severe hepatic impairment. Starting or continuing Genvoya during pregnancy requires specialist review because cobicistat exposure can decrease in later trimesters.

Genvoya interacts with many drugs due to cobicistat. Review antiseizure medicines, antimycobacterials, certain statins, sedatives, and herbal products. Discuss vitamin and mineral supplements because calcium, iron, and magnesium can affect integrase inhibitor absorption. Take Genvoya with food to maintain reliable exposure and viral suppression.

To manage costs, consider a 60–90 day supply to reduce per-month pricing. You can request reorder reminders so refills are on time. Patients paying cash or comparing Genvoya without insurance often find Canadian pricing more affordable than many US pharmacies.
