Tenvir EM® Tablets for HIV Prevention and Treatment

Tenvir EM® combines emtricitabine and tenofovir disoproxil for HIV prevention and for use with other antiretrovirals in treatment. This page explains how it works, key safety points, and ways to plan access even without insurance.

What Tenvir EM Is and How It Works

This medicine supports US delivery from Canada for eligible prescriptions. Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing. It contains two nucleoside reverse transcriptase inhibitors that help block HIV replication. As part of treatment, it partners with other antiretrovirals. As prevention, it helps reduce the chance of getting HIV when used with safer‑sex practices.

Tenvir Em Uses are aligned with established labeling for Truvada. Emtricitabine/tenofovir disoproxil fumarate 200/300 mg tablets are taken once daily. The treatment is also active against hepatitis B virus, so stopping suddenly can cause serious HBV flares. Your clinician may order baseline tests and periodic monitoring to guide safe use.

Who It’s For

This therapy is indicated for HIV‑1 pre‑exposure prophylaxis (PrEP) in adults and adolescents at risk, when HIV‑negative status is confirmed. It is also used for HIV‑1 treatment as part of a complete regimen. People with known HIV infection must not use PrEP alone. Those with significant kidney disease, untreated bone disorders, or unknown HIV status should discuss risks and alternatives with a clinician. Screening for hepatitis B is recommended before starting, since stopping can worsen HBV.

Dosage and Usage

For PrEP, take one tablet by mouth once daily, with or without food. Confirm HIV‑negative status before starting, then test regularly as advised on the label, typically every three months during ongoing use. Consistent daily dosing and safer‑sex practices are important to help reduce risk. If you develop symptoms of acute HIV infection, contact your healthcare professional for testing before continuing PrEP.

For HIV‑1 treatment, this medicine is taken once daily as part of a complete antiretroviral regimen. Your prescriber will select companion medicines appropriate for your history and lab results. Kidney function should be assessed before initiation and monitored during therapy. Follow the official label or your prescriber’s directions; do not change doses on your own.

Strengths and Forms

This treatment is supplied as film‑coated oral tablets. Commonly published strength: emtricitabine 200 mg with tenofovir disoproxil fumarate 300 mg per tablet. Availability can vary by partner pharmacy and manufacturer.

Some patients and clinicians may refer to it as Generic Truvada 200/300 mg tablets, reflecting the active ingredients and standard presentation.

Missed Dose and Timing

If you miss a dose, take it as soon as you remember the same day. If it is almost time for the next dose, skip the missed dose and take the next dose at the usual time. Do not double up. For PrEP, steady daily use matters; set reminders or use a pillbox to support consistency.

Storage and Travel Basics

Store tablets at room temperature in the original container, tightly closed, and keep the desiccant in place. Protect from excess moisture and keep out of reach of children and pets. For travel, carry enough tablets for your trip plus a few extra days. Keep medicine in your hand luggage with your prescription details. If crossing borders, bring a copy of your prescription or pharmacy receipt. Do not store tablets in a car or other places with extreme heat or humidity.

Benefits

As part of prevention, this medicine can help reduce the chance of acquiring HIV when taken consistently with safer‑sex practices. As part of treatment, combining two nucleoside reverse transcriptase inhibitors in one tablet supports a simplified, once‑daily backbone within a complete regimen. Many prescribers value this convenience for eligible patients. Ongoing monitoring supports safety while maintaining a steady routine.

Side Effects and Safety

• Common: nausea, diarrhea, headache
• Sometimes: dizziness, tiredness, abdominal discomfort
• Lab changes: effects on kidney function, possible decreases in bone mineral density

Serious but less common risks can include kidney problems, lactic acidosis, severe liver enlargement with steatosis, and worsening of hepatitis B after stopping. Seek urgent care for symptoms like persistent vomiting, rapid breathing, unusual muscle pain, yellowing of skin or eyes, or markedly reduced urination. For PrEP, new HIV symptoms require immediate testing; do not continue PrEP until status is clarified.

Drug Interactions and Cautions

Tell your prescriber about all medicines and supplements. Drugs that can affect the kidneys may raise risk; examples include high‑dose or multiple NSAIDs and certain antivirals. Some hepatitis C combinations and boosted regimens can increase tenofovir exposure. Avoid combining with other medicines that contain emtricitabine, lamivudine, or tenofovir to prevent duplication. If you have bone disease, kidney impairment, or chronic hepatitis B, your clinician may consider additional monitoring or alternatives. See the official label for a full interaction list.

What to Expect Over Time

With PrEP, protection builds with consistent daily use and safer‑sex practices. Missed doses can reduce effectiveness. Your care team will likely check HIV status regularly, review side effects, and reinforce adherence strategies. In treatment, response depends on the full regimen and adherence; lab tests track viral load, CD4 count, and kidney function. If you and your prescriber decide to stop therapy and you have chronic hepatitis B, monitoring for flares is important.

Compare With Alternatives

Several approved options may be appropriate based on your history, lab results, and goals.

• Dovato: a complete 2‑drug regimen for certain adults starting therapy or maintaining suppression.
• Pifeltro: a non‑nucleoside option used with other agents in optimized regimens.

Your clinician can help weigh regimen simplicity, interactions, and organ health. Our article library offers deeper background on choices and evolving guidelines.

Availability and Substitutions

Supply can vary by manufacturer and lot. If an item is temporarily unavailable, your prescriber may recommend a clinically appropriate alternative or a different NRTI backbone based on your labs and history. Country of manufacture may differ by lot; some suppliers source from India. We cannot promise restock dates, but we will suggest comparable options where appropriate.

Patient Suitability and Cost-Saving Tips

This therapy may suit adults and adolescents at risk for HIV who can adhere to daily dosing and routine testing. It may not be right for people with significant kidney disease without close monitoring. To reduce costs, consider multi‑month fills when appropriate, which can lower per‑fill fees and reduce travel time. Set calendar reminders for refills so you do not miss doses. If paying cash, ask your prescriber about longer prescriptions that allow fewer pharmacy visits.
