Merck Patient Assistance Program Patient Guide: How to Get DELSTRIGO (doravirine/lamivudine/tenofovir disoproxil fumarate) at Low or No Cost

DELSTRIGO is a prescription medication used to treat HIV-1 infection in adults and children weighing at least 35 kg who are treatment-naïve or switching from other antiretroviral regimens. This guide explains how the Merck Patient Assistance Program (PAP) can provide DELSTRIGO at no cost if you qualify, primarily targeting uninsured patients or those not meeting insurance criteria.[1][2]

About DELSTRIGO

DELSTRIGO combines three antiretroviral drugs—doravirine, lamivudine, and tenofovir disoproxil fumarate—into one tablet taken once daily. It works by inhibiting HIV replication through different mechanisms: doravirine blocks the reverse transcriptase enzyme, while lamivudine and tenofovir disoproxil fumarate further disrupt viral DNA production. This complete regimen helps manage HIV-1, reduce viral load, and improve immune function. Always take it as prescribed by your healthcare provider (HCP), typically with or without food, but consult them for personalized advice. Common side effects may include headache, fatigue, nausea, diarrhea, and sleep disturbances; serious risks include lactic acidosis, liver problems, or bone density loss—report any unusual symptoms immediately.[1]

Who Qualifies for the Merck Patient Assistance Program?

The Merck PAP helps U.S. residents (including territories, no citizenship required) who have a prescription for a covered Merck medicine like DELSTRIGO from a U.S.-licensed HCP. It's primarily for uninsured patients or those whose insurance doesn't cover the medication adequately. Some insured patients who don't meet their plan's criteria may still qualify, but it's not available for government insurance like Medicare or Medicaid per related savings offers. You must meet financial eligibility, determined by the program via electronic verification or provided documents. Enrollment is typically valid for up to 12 months, with reauthorization required annually or sooner if circumstances change.[1][3][6][8]

Income Eligibility Breakdown

Specific income thresholds (e.g., Federal Poverty Level percentages) are not publicly detailed in program materials but are assessed case-by-case, often up to 500% of the FPL or similar for uninsured. The program prioritizes those with limited resources. Use this table for a general understanding based on program notes:

*Exact limits verified during application; program may request audits. Call 800-727-5400 for details.[3][8]

Insurance Requirements

Primarily for uninsured patients. If you have private insurance that doesn't cover DELSTRIGO or excludes you from benefits, you may qualify. However, patients with government insurance (e.g., Medicare, Medicaid, VA) are generally ineligible through this PAP. Your HCP and you must certify no alternative funding requires PAP application. The program reserves the right to verify coverage.[1][4]
