Who Qualifies for the Merck Patient Assistance Program?

If you need Janumet but cannot afford it, the Merck Patient Assistance Program may be able to help you get it at little or no cost. The program is designed primarily for people who do not have prescription drug insurance, but some insured patients may also qualify under certain conditions.

To be eligible, you generally need to meet income guidelines. For a single-person household, your annual income must be $63,840 or less. Larger households have higher limits, which are covered in detail below.

If you are uninsured, you are the primary focus of this program. If you have insurance, you may still qualify through a hardship exception — but you must meet the income criteria and cannot be enrolled in certain other assistance programs.

About Janumet (Sitagliptin/Metformin)

Janumet is a prescription combination medication used to manage type 2 diabetes mellitus in adults. It combines two separate drug classes — sitagliptin, a DPP-4 inhibitor, and metformin, a biguanide — into a single tablet taken by mouth. Merck manufactures Janumet, and it is available in multiple dosage strengths.

Without insurance or assistance, Janumet can cost several hundred dollars per month, putting it out of reach for many patients. Because it is a brand-name combination drug, its price does not yet reflect the lower costs typically associated with generics. The Merck Patient Assistance Program exists specifically to address this gap for eligible patients.

Income Eligibility: Full Breakdown

Merck uses household size and annual income to determine whether you qualify. The income limits are set at approximately 425% of the Federal Poverty Level (FPL). Here is how the thresholds break down:

| Household Size | Maximum Annual Income |

|---|---|

| 1 person | $63,840 |

| 2 persons | $86,560 |

| 3 persons | $109,280 |

| 4 persons | $132,000 |

For households larger than four people, the income limit increases by approximately $22,720 for each additional person, though you should confirm the exact figure with Merck directly.

When you apply, you will typically need to document your income using your most recent federal tax return or three months of recent pay stubs. If you are self-employed or have irregular income, other documentation may be accepted.

If your income is above the limit for your household size, you will likely not qualify for free medication through this program. However, you are not out of options — see the "Alternatives" section below for other ways to reduce your costs.

What to Expect: Timeline and Delivery

Merck does not publish a specific processing time for this program, so timelines can vary. Once approved, Merck will notify you or your prescriber. Medication may be delivered directly to your home or to your prescriber's office, depending on how your application was set up. If delivery goes to your doctor's office, you will need to contact them to arrange pickup — no co-pay is required at pickup for approved patients.

Your enrollment is not permanent. Annual reauthorization is required, which means you will need to reapply each year and re-confirm your eligibility. Watch for expiration notices and plan ahead to avoid a gap in your medication supply.

Alternatives If You Don't Qualify

If you do not meet the program's criteria, you still have options:

1. Generic alternatives: Both sitagliptin and metformin hydrochloride are available as separate generic medications. Ask your doctor whether switching to generic versions of each drug individually would be appropriate for your treatment plan.

2. Janumet Savings Card: If you have commercial insurance, you may be eligible for a manufacturer savings card that can reduce your out-of-pocket costs. Visit https://www.janumet.com/special-offers/ to see current offers.

3. State Pharmaceutical Assistance Programs (SPAPs): Many states run their own drug assistance programs, especially for seniors and people with disabilities. Search for your state's program through your state health department website.

4. NeedyMeds.org: This free, nonprofit database lists hundreds of assistance programs by drug name, diagnosis, and state. It is a useful starting point if Merck's program is not a fit for your situation.
