Viread® Tablets for Chronic Hepatitis B

Viread® is a prescription antiviral used for chronic hepatitis B and, with other medicines, HIV-1. This page explains how it works, standard use, and key safety points, with US delivery from Canada. It also outlines access options if you are paying without insurance.

What Viread Is and How It Works

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

This medicine contains tenofovir disoproxil fumarate, a prodrug of tenofovir. It belongs to the nucleotide reverse transcriptase inhibitor class. Inside the body, it converts to tenofovir diphosphate, which blocks viral reverse transcriptase. That action helps reduce hepatitis B virus replication and supports combination HIV-1 therapy. When taken as directed, the treatment can lower viral load and support liver health. For HIV, it must be used with other active antiretrovirals.

If your clinician prescribed this therapy for Hepatitis B, they will monitor your response with labs. Do not stop this medicine without medical guidance, since hepatitis may flare after discontinuation. Review the official labeling for full details and precautions.

Many people want to understand access and costs. We explain options, how refills work, and how you can store and travel with the tablets safely.

Viread for hepatitis B

Who It’s For

This treatment is indicated for adults with chronic hepatitis B. It is also used, with other antiretrovirals, for HIV-1 in appropriate patients. Your prescriber will determine suitability based on your diagnosis, kidney function, bone health, and medication history. People with known hypersensitivity to any ingredient should not take it.

Use caution if you have reduced kidney function, a history of bone loss, or risk factors for lactic acidosis. Children, pregnant individuals, and those with significant comorbidities require clinician oversight and label-based guidance. For HIV-1, it is part of combination therapy and not used alone.

Dosage and Usage

Follow your prescriber’s instructions on dose and schedule. The tablets are typically taken once daily, with or without food, at around the same time each day. Swallow tablets whole with water. If your clinician adjusts dosing due to kidney function, follow their plan and the label rather than making changes yourself.

Take missed doses as described below. Keep a medication list and share it with every healthcare professional you see. Routine blood tests may include kidney metrics, liver enzymes, hepatitis B DNA or HIV-1 RNA, and bone health markers when appropriate.

Strengths and Forms

Commonly available presentations include:

• Tenofovir disoproxil fumarate 300 mg tablets
• Oral powder (commonly 40 mg per gram), used when tablets are not suitable

Availability may vary by manufacturer and market. Your prescription will specify the form and quantity. If a given presentation is not suitable for you, speak with your prescriber about alternatives.

Missed Dose and Timing

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and resume your usual schedule. Do not take two doses at once. Consistent daily timing helps maintain antiviral activity and reduces the chance of resistance. Use a reminder system if needed.

Storage and Travel Basics

Store tablets at room temperature, away from moisture and excessive heat. Keep the bottle tightly closed and out of reach of children and pets. Do not use tablets that are damaged or expired. When traveling, carry your medicine in original packaging with a copy of your prescription. Use a carry-on bag to avoid temperature extremes. If you have connecting flights or long trips, plan dosing around your schedule and time zones to avoid missed doses.

Benefits

As a nucleotide analog, this medicine can suppress hepatitis B viral replication and help normalize liver enzymes over time. In HIV-1, it supports combination regimens that aim to achieve and maintain viral suppression. Once-daily dosing is convenient, and the oral powder option can be helpful when tablets are not appropriate. Your clinician will track your labs and clinical status to assess benefit.

Side Effects and Safety

• Common effects: nausea, diarrhea, headache, dizziness, rash, and fatigue
• Kidney concerns: increased creatinine, proteinuria, or Fanconi syndrome
• Bone effects: decreased bone mineral density, osteomalacia in rare cases
• Liver considerations: hepatitis flares after stopping therapy

Serious risks include lactic acidosis and severe hepatomegaly with steatosis. For HIV-1, immune reconstitution syndrome can occur when starting active therapy. Seek medical help for signs of severe weakness, deep or rapid breathing, persistent abdominal pain, or yellowing of skin or eyes. Your prescriber may order bone density or renal tests if risk factors are present.

Drug Interactions and Cautions

Tell your healthcare professional about all medicines, vitamins, and supplements. Avoid adefovir. Use caution with other nephrotoxic agents, including high-dose or multiple NSAIDs. Pharmacokinetic boosters and certain antiretrovirals can raise tenofovir levels; your regimen may need careful selection. Antacids or supplements with polyvalent cations can affect absorption of some medicines; review your schedule with your prescriber or pharmacist.

If you live with HIV-1, regimens are individualized. Category pages like Hiv and Antivirals provide additional context on related therapies.

What to Expect Over Time

With regular use, your clinician may see reduced hepatitis B DNA and improvements in liver enzymes. For HIV-1, the goal is durable viral suppression as part of a complete regimen. Side effects are often mild and improve with continued therapy, but monitoring remains essential. If this medicine is stopped, your prescriber will watch for hepatitis flares. Stay consistent with dosing, attend lab appointments, and report new symptoms promptly.

Compare With Alternatives

For chronic hepatitis B, prescribers may consider other nucleos(t)ide analogs. Vemlidy contains tenofovir alafenamide, a related agent with different pharmacokinetics. Baraclude contains entecavir, another first-line option in several guidelines. Selection depends on kidney and bone considerations, resistance patterns, comorbid conditions, and co-infection status.

Availability and Substitutions

Supply varies by manufacturer and pack size. If a specific presentation is unavailable, your prescriber may recommend an appropriate alternative. Authorized generics may be available and can be suitable when clinically appropriate. Your pharmacy team will dispense according to the prescription and applicable regulations.

Patient Suitability and Cost-Saving Tips

Good candidates are those with an appropriate diagnosis, adherence support, and acceptable kidney and bone health. People with severe renal impairment, active lactic acidosis, or known intolerance require individualized evaluation. To save on ongoing therapy, consider multi-month fills when appropriate, set up refill reminders, and coordinate lab schedules to avoid gaps. Discuss generic options with your prescriber if suitable for your plan.
