FAQ

A prescription is required to obtain lamivudine from local pharmacies in Canada. Our store policy allows you to order this medicine without a prescription and have it sent by mail.

Do not crush, chew, or split the tablets unless the package information or a prescriber confirms that this is appropriate for the specific product. If swallowing tablets is difficult, ask a pharmacist or prescriber about a suitable alternative formulation or administration plan.

They may differ. The supplied product's exact inactive ingredients are not confirmed in advance, so check the received package label or leaflet if you need to avoid a particular ingredient because of an allergy or intolerance.

Check the package label for lamivudine, the dosage form of tablets, and the strength of 150 mg. Also compare the manufacturer, lot number, expiry date, and any tablet imprint when present with the package information; do not take the tablets if the ingredient, strength, or dosage form is different from what was ordered.

Tablets can normally travel by mail when packed to protect them from moisture, damage, and inappropriate temperatures. Keep them in their original packaging and, after arrival, check that the package is intact and store the tablets at 25°C; excursions from 15°C to 30°C are permitted.

This product is available as oral tablets containing 150 mg of lamivudine. Package quantities available are 30, 60, 90, 120, 180, or 240 tablets.

Epivir contains lamivudine, an antiviral medicine used with other antiretroviral medicines to treat HIV infection. Lamivudine is also used in some treatment plans for chronic hepatitis B, but the appropriate product and regimen differ, so this 150 mg tablet listing should not be assumed to be suitable for hepatitis B treatment.

Pregnancy requires an individual clinical assessment: lamivudine may be used when the expected benefit outweighs potential risk, but HIV treatment should be managed by the treating clinician. Breastfeeding should be avoided because lamivudine passes into breast milk and HIV can be transmitted through breast milk.

Lamivudine tablets are taken by mouth, with or without food, as part of combination HIV treatment. A common adult HIV regimen is 150 mg twice daily or 300 mg once daily, but the selected regimen depends on the other antiretrovirals and kidney function. Take it on the prescribed schedule and do not use lamivudine alone for HIV treatment.

Common effects include headache, nausea, tiredness or malaise, diarrhoea, cough, and nasal symptoms. Seek urgent medical advice for severe or persistent abdominal pain, vomiting, unusual weakness, shortness of breath, yellowing of the skin or eyes, or signs of a serious allergic reaction. People with hepatitis B need medical monitoring if lamivudine is stopped because liver disease can worsen after discontinuation.

Description

Note: Images in the description are provided for informational purposes and may differ from the actual appearance of the product. Please refer to the product name, strength, ingredients, and dosage form.

Epivir 150 mg contains lamivudine (also known as "3TC"), a nucleoside reverse transcriptase inhibitor (NRTI) used with other antiretroviral medications to treat HIV-1 infection.

How it works

Inside cells, lamivudine is converted into an active triphosphate form that inhibits HIV reverse transcriptase and blocks viral DNA synthesis. When taken as part of a complete antiretroviral regimen, it helps reduce viral replication.

Can Epivir (lamivudine) prevent HIV?

Epivir is mainly used to treat people living with HIV and is not used on its own for pre-exposure prophylaxis (PrEP). For prevention, clinical guidelines typically recommend dedicated PrEP options, such as tenofovir/emtricitabine or long-acting cabotegravir, depending on eligibility and local guidance.

For PrEP or post-exposure prophylaxis (PEP) options, speak with a Canadian clinician to choose the most appropriate one.

Usual dosing (HIV-1)

  • Adults and adolescents: total daily dose 300 mg, taken as 150 mg twice daily or 300 mg once daily, as prescribed.
  • Can be taken with or without food.
  • A dose adjustment may be needed in renal impairment.

Abacavir plus lamivudine (ABC/3TC)

Abacavir + lamivudine (ABC/3TC) is a widely used backbone combination for HIV treatment. In some countries, it is available as a single fixed-dose tablet (for example, Epzicom or Kivexa) and is taken together with at least one other antiretroviral medication.

Epivir 150 mg tablets

Before starting abacavir-containing regimens, clinicians typically consider human leukocyte antigen B*5701 (HLA-B*5701) screening because of the risk of serious hypersensitivity reactions.

Important information

  • Epivir is taken with other antiretroviral medications (not as monotherapy for HIV).
  • If you have HIV and hepatitis B virus (HBV), stopping lamivudine may cause a severe HBV flare. Do not stop treatment without medical advice.
  • Get urgent medical help if you have symptoms that suggest lactic acidosis or severe liver problems.

Customer questions

Asked by Asha, Iqaluit, Canada

I'm in Iqaluit and want to order lamivudine. How can I find out whether you can ship to my address before I place the order?

Answered by Support team

Delivery availability for remote addresses can vary. Enter your complete Iqaluit address and postal code at checkout to check whether the destination can be accepted before you pay.

Asked by Maria, Windsor, Canada

My lamivudine package arrived in Windsor after several very cold days. What should I look for before I use the tablets?

Answered by Support team

Check that the outer package and tablet packaging are intact, dry, and properly labelled, with no damaged seal or visibly altered tablets. Store the tablets at 25°C, with permitted excursions from 15°C to 30°C; if the package or tablets appear compromised, do not use them until the discrepancy is assessed.

Asked by Noah, Oshawa, Canada

I had hives from penicillin years ago. Does that mean I should avoid lamivudine?

Answered by Support team
Medical reviewed by Donna Brettler

A penicillin allergy does not by itself indicate a known cross-reaction with lamivudine. Lamivudine should be avoided only if there has been a previous allergy to lamivudine itself or to an ingredient in the particular tablet; check the received label for excipients if you have a known ingredient allergy.
