Pifeltro Information

Pifeltro at CanadaPharmacyOnline.com

Brand Pifeltro (doravirine) is manufactured by Merck in many countries worldwide, including Canada.

The generic doravirine is currently unavailable (at this pharmacy).

Dosage:

Pifeltro is commonly available as 100 mg oral tablets.

Your doctor will determine the appropriate dose based on your individual needs and medical conditions.

Usage:

Pifeltro (doravirine) is a prescription medication primarily used to treat human immunodeficiency virus type 1 (HIV-1) infection. It is taken as part of a combination antiretroviral therapy regimen. HIV attacks the immune system, specifically CD4 cells, which weakens the body's ability to fight infections. Without effective treatment, HIV can progress and cause serious illness. When used consistently with other HIV medicines, Pifeltro helps reduce viral load and support immune function.

Mechanism of Action:
Pifeltro (doravirine) is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It works by blocking reverse transcriptase, an enzyme HIV needs to copy its genetic material and multiply. By interfering with this process, doravirine helps slow viral replication and limit further damage to the immune system.

Take Pifeltro exactly as your doctor prescribes, following the instructions in the product monograph accompanying the medication. Consult your doctor for personalized guidance and safe use.

Why is Pifeltro more affordable in Canada than in the United States?

Prescription drug prices, including Pifeltro, are generally lower in Canada than in the U.S. due to a combination of factors, primarily government price regulations, differing market dynamics, and other economic considerations.
