Viread® Tablets for HIV-1 and Chronic Hepatitis B

Viread® is an antiviral tablet used to treat HIV-1 and chronic hepatitis B. This page explains how it works, who it suits, and how to use it safely. It also covers Viread cost without insurance and US delivery from Canada.

What Viread Is and How It Works

Viread® contains tenofovir disoproxil fumarate, a nucleotide reverse transcriptase inhibitor. It is a prodrug converted in the body to tenofovir, which blocks viral reverse transcriptase and hepatitis B polymerase. By interrupting viral DNA synthesis, this medicine helps reduce HIV-1 replication and suppresses hepatitis B virus activity. It is used as part of a combination regimen for HIV-1 and as monotherapy or combination therapy for chronic hepatitis B in suitable patients.

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

This treatment is generally taken once daily and may be taken with or without food. Your prescriber will base your plan on recognized guidelines and the official label. Many factors influence Viread price, including quantity and market availability.

Who It’s For

This treatment is indicated for adults and adolescents who meet label criteria for HIV-1 infection, and for eligible patients with chronic hepatitis B. It can be appropriate for people who can take a once-daily tablet and for those whose clinicians think a tenofovir-based regimen is suitable. People with significant kidney problems, a history of bone disorders, or severe liver disease may require a different approach or closer monitoring. If you are pregnant, planning pregnancy, or breastfeeding, discuss the risks and benefits with your healthcare professional.

Individuals with both HIV and hepatitis B require careful planning to avoid viral flare after changes to therapy. Children and those with difficulty swallowing tablets may need an alternative form or dosing approach as directed by a prescriber.

Dosage and Usage

For HIV-1, this medicine is used together with other antiretrovirals. The typical adult schedule is once daily, taken consistently at the same time each day. For chronic hepatitis B, a once-daily schedule is also used. It may be taken with or without food. Swallow tablets whole with water. Do not split, crush, or chew unless your clinician advises otherwise.

Renal function influences dosing intervals. If you have kidney impairment, your prescriber will consult the official labeling for adjustments. Always follow your clinician’s instructions and keep all recommended lab appointments for kidney function and, when relevant, bone monitoring. A valid prescription is required to buy tenofovir disoproxil fumarate.

Strengths and Forms

This medicine is supplied as film-coated tablets. Labeling may differ by region.

• Tablets: commonly labeled as 300 mg (North America) or 245 mg (some regions)

Availability can vary by market and manufacturer. Your pharmacist will dispense what your prescription specifies and what is available in your jurisdiction.

Missed Dose and Timing

If you miss a dose, take it as soon as you remember unless it is close to the time for your next dose. If it is almost time for the next dose, skip the missed dose and resume your regular schedule. Do not take two doses at the same time. Consistent daily dosing supports viral suppression in HIV-1 and helps maintain control of hepatitis B.

Storage and Travel Basics

Store tablets in the original, tightly closed container and protect from moisture. Keep out of reach of children and pets. Check the label for typical room-temperature guidance and avoid storing in places with high humidity, such as bathrooms. When traveling, keep your medicine in carry-on luggage with the pharmacy label visible. Bring enough tablets for your trip and a few extra in case of delays. If you use a pill organizer, carry a copy of your prescription. Our parcels use temperature-controlled handling when required.

Benefits

This therapy offers once-daily dosing and can be taken with or without food, which may support adherence. As part of a complete HIV regimen, it helps suppress viral replication. For chronic hepatitis B, it can help reduce viral load and support liver health as part of a comprehensive care plan. The tablet form is convenient for many adults and adolescents. Ongoing use is typically combined with regular monitoring and routine clinic follow-up.

Side Effects and Safety

• Headache
• Nausea
• Diarrhea
• Dizziness
• Fatigue
• Rash
• Back pain
• Insomnia

Serious or rare risks can include kidney function changes, protein in the urine, and bone mineral density loss. Lactic acidosis and severe hepatomegaly with steatosis have been reported with nucleoside analogs; seek urgent care if you develop concerning symptoms. In people with hepatitis B, stopping treatment can cause a severe flare; your clinician will monitor liver function if therapy changes. Contact your healthcare professional promptly if you notice decreased urination, swelling, bone pain, or persistent gastrointestinal symptoms.

Drug Interactions and Cautions

Avoid combining with other medicines that affect the kidneys unless your clinician advises and monitors closely. Certain antivirals, such as didanosine, and regimens containing atazanavir without a booster may have important interactions. Do not coadminister with adefovir dipivoxil. Tell your prescriber and pharmacist about all prescription drugs, over-the-counter products, supplements, and herbal remedies you use. Alcohol use, dehydration, or high-dose NSAIDs can increase kidney stress; ask your clinician about safe use. Laboratory monitoring of kidney function and, when appropriate, bone health is recommended during therapy.

What to Expect Over Time

With consistent use and a complete HIV regimen, viral load may decline as assessed by lab testing. For chronic hepatitis B, clinicians monitor viral DNA and liver enzymes to gauge response. You might not feel different day to day, so lab results and follow-up visits are essential. If your prescriber adjusts therapy, follow instructions carefully to avoid viral breakthrough or hepatitis B flare. Keeping doses at the same time daily and planning ahead for refills can support steady control.

Educational resources can help you stay informed. For background on combination HIV therapy, see our overview on Delstrigo Facts. Community testing awareness is covered in HIV Testing Day. Condition pages such as HIV, Hepatitis B, and Antivirals may provide further context.

Compare With Alternatives

Some patients may use a single-tablet HIV regimen that includes a tenofovir backbone. One option is Delstrigo® (doravirine/lamivudine/tenofovir disoproxil), which combines three agents in one daily tablet. Others may use a core integrase inhibitor with a separate backbone, such as Tivicay® (dolutegravir) with nucleoside analogs. Your prescriber will choose a regimen based on guidelines, resistance profile, comorbidities, and your treatment goals.
