Can I take this regimen with antacids or supplements?

Some antacids and mineral supplements can reduce absorption of the integrase inhibitor. Products containing aluminum or magnesium should be taken at a different time. Iron or calcium may be taken with food or separated per the label. Keep a consistent schedule and ask your pharmacist to review your exact products. Never change dosing based on general advice; follow the official prescribing information and your clinician’s guidance.

What if I stop therapy and have hepatitis B?

In people with chronic hepatitis B, stopping this medicine can cause serious flare-ups of hepatitis. Clinicians usually monitor liver tests and may arrange additional follow-up after discontinuation. Do not stop on your own. If you have HBV, discuss a plan with your prescriber before any change. Seek urgent care if you notice jaundice, dark urine, severe fatigue, or right‑upper‑quadrant pain after stopping treatment.

How quickly should I expect changes in my viral load?

Response varies by person and prior treatment history. Many patients see viral load reductions with consistent daily dosing, but the exact timing is individualized. Your clinician will schedule lab tests to track progress. Keep taking your tablet every day, even if you feel well, and attend follow-up visits. Report any adherence barriers so your care team can help address them.

Are there medicines I must avoid with this treatment?

Avoid strong enzyme inducers like rifampin and herbal products such as St. John’s wort. Some anticonvulsants and certain hepatitis C therapies may also interact. Over-the-counter antacids with aluminum or magnesium need separation from your dose. Bring a complete list of prescriptions and supplements to your pharmacist or prescriber for review. They can check for interactions using your full medication profile.

How should I store the tablets at home and during travel?

Keep the tablets in the original bottle with the desiccant, tightly closed, at room temperature. Protect from moisture and excessive heat. Store out of reach of children and pets. When traveling, keep the labeled container in your carry-on along with your prescription. If crossing borders, carry a medication list or a note from your healthcare professional. Follow the same storage guidance at your destination.

What are common side effects and when should I seek help?

Common effects include headache, nausea, diarrhea, and fatigue. These are usually mild. Serious problems are uncommon but can involve liver issues, lactic acidosis, kidney concerns, or immune reconstitution syndrome. Seek medical attention for severe rash, yellowing of the skin or eyes, dark urine, trouble breathing, or extreme weakness. Discuss any persistent or bothersome symptoms with your prescriber.

Can adolescents use this medication?

Yes, certain adolescents may be candidates when they meet weight and clinical criteria defined in the prescribing information. The healthcare professional will assess treatment history, potential interactions, and organ function. Dosing uses a specific tablet strength determined by the prescriber. Caregivers should support daily adherence and keep follow-up appointments for lab monitoring and safety checks.

Biktarvy is a prescription HIV-1 treatment for adults and adolescents. This page explains what it is, who it suits, and how to use it. We provide US delivery from Canada, and show Biktarvy price without insurance for planning.

What Biktarvy Is and How It Works

This complete regimen combines an integrase strand transfer inhibitor with two nucleoside analogs. It blocks HIV replication at multiple steps in the viral cycle. That helps reduce viral load when taken as directed. Visit our HIV category for broader background on antiretroviral care.

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

Biktarvy® contains bictegravir, emtricitabine, and tenofovir alafenamide. It is a single daily tablet used as the entire regimen for many people living with HIV-1. The treatment may be started in those without prior antiretroviral therapy, or used to replace a stable regimen when certain criteria are met.

Who It’s For

This medicine is indicated for adults and eligible adolescents with HIV-1. It may be used in those starting therapy or in people who are virologically suppressed and have no known resistance to its components. People with chronic hepatitis B need careful evaluation because stopping therapy can lead to serious flare-ups of hepatitis.

Avoid this therapy if your prescriber has identified significant drug interactions or contraindications. Those with severe renal impairment may not be candidates. Discuss pregnancy, plans to conceive, and breastfeeding with your healthcare professional.

Dosage and Usage

Take one tablet by mouth once daily. You can take it with or without food. Swallow the tablet whole with water. Keep to the same time each day to support adherence.

Separate dosing from aluminum or magnesium-containing antacids as advised on the label. If you take iron or calcium supplements, follow label guidance about timing. Do not change your regimen or stop therapy without clinician direction.

If uncertain about any step, consult the official prescribing information and your prescriber.

Strengths and Forms

This therapy is supplied as film‑coated tablets. Common presentations include adult and pediatric strengths; availability may vary by market and supplier.

Biktarvy 50mg/200mg/25mg tablets
Pediatric strength also exists; your prescriber will specify the correct tablet

Missed Dose and Timing

If you miss a dose, take it as soon as you remember. If it is close to the time of your next dose, skip the missed tablet and resume your regular schedule. Do not double up. If you vomit shortly after taking a dose, consult the label or your healthcare professional about whether to take another tablet.

Storage and Travel Basics

Store tablets at room temperature in the original bottle, tightly closed. Keep the desiccant in the bottle to protect from moisture. Protect from excessive heat and humidity. Keep out of reach of children and pets.

When you travel, pack your medication in your carry-on. Keep it in the original labeled container for security checks. Bring a copy of your prescription. If crossing borders, allow extra time for screening and carry a medication list from your clinician. For storage at your destination, follow the same room-temperature guidance.

Benefits

This single-tablet regimen simplifies daily HIV care. Once-daily dosing can help support adherence. The integrase inhibitor component provides a high barrier to resistance when taken correctly. The combination is designed to be a complete regimen without additional antiretrovirals in most eligible patients.

Side Effects and Safety

Common: headache, nausea, diarrhea, fatigue, sleep changes
Less common: abdominal discomfort, rash, dizziness

Serious risks are uncommon but can include liver problems, lactic acidosis with severe hepatomegaly, new or worsening kidney concerns, immune reconstitution syndrome, and depressive symptoms. In people with hepatitis B, stopping therapy can cause serious hepatic flare-ups; clinicians monitor closely. Seek urgent care for severe rash, jaundice, dark urine, shortness of breath, or unusual weakness.

Drug Interactions and Cautions

Strong enzyme inducers can lower drug levels and reduce effectiveness. Avoid rifampin and St. John’s wort. Certain anticonvulsants and some tuberculosis or hepatitis C agents may interact. Space dosing from antacids containing aluminum or magnesium. Ask your pharmacist before taking over-the-counter supplements, including iron or calcium, to confirm timing. Alcohol does not have a known direct interaction but may complicate adherence and liver health.

What to Expect Over Time

With consistent daily use, viral load may decline and remain suppressed as guided by your clinician’s monitoring. CD4 counts may improve gradually. You will have periodic lab tests to check kidney and liver health. If you feel well, continue taking the tablet daily as prescribed; missing doses can allow the virus to rebound. Keep all follow-up visits and discuss any new medicines before starting them.

Compare With Alternatives

Several complete regimens are available for first-line or switch therapy. Options include integrase-based and non-nucleoside combinations. Your prescriber will select a regimen based on resistance patterns, comorbidities, and potential interactions.

Comparable single-tablet alternatives include Genvoya and Delstrigo. A pack size such as Biktarvy 30 tablets is common for monthly fills. Another alternative, Triumeq, contains an integrase inhibitor with abacavir and lamivudine; genetic testing for HLA‑B*5701 is required before using abacavir. For background on non-nucleoside options, review Delstrigo Medication For Hiv.
