About This Medication
# Merck Patient Assistance Program Patient Guide: How to Get Januvia at Low or No Cost ## About This Program The **Merck Patient Assistance Program** provides free or low-cost Januvia (sitagliptin phosphate) to eligible patients who cannot afford their medication. Januvia is a prescription diabetes medication used to help control blood sugar levels in adults with type 2 diabetes. If you have been prescribed Januvia and meet the program's eligibility requirements, you may receive your medication at no cost. ## Who Qualifies for This Program To be eligible for the Merck Patient Assistance Program, you must meet **all three** of the following conditions: 1. **You are a US resident** with a valid prescription for Januvia from a licensed US healthcare provider. You do not need to be a US citizen; residents of US territories are also eligible. 2. **You have no insurance or other coverage** for your prescription medication. This includes private insurance, HMOs, Medicaid, Medicare, state pharmacy assistance programs, Veterans' assistance, or any other social service agency support. If you have insurance but face special circumstances of financial and medical hardship, you may request an exception. 3. **Your household income is at or below the program's income limits** (see Income Eligibility section below). ## Income Eligibility Breakdown The Merck Patient Assistance Program uses income thresholds based on 400% of the Federal Poverty Level (FPL). Your household income must not exceed the following amounts: | Household Size | Maximum Annual Income | |---|---| | Individual | $60,780 | | Couple | $60,780 | | Family of 3+ | 400% FPL (varies by year) | These income limits are updated annually. If your income is slightly above these thresholds but you face significant financial or medical hardship, you can request an exception to the income requirement. ## Insurance Requirements and Medicare The program requires that you **do not have active insurance coverage** for prescription medications. However, **Medicare Part D patients may be eligible**—contact the program directly at 1-800-727-5400 to discuss your specific situation. If you have insurance through an employer, private plan, Medicaid, or other coverage, you typically will not qualify unless you can demonstrate special circumstances of financial and medical hardship that warrant an exception. ## How to Apply: Step-by-Step ### Step 1: Obtain the Application Form You can get the enrollment form in three ways: - **Call** 1-800-727-5400 (8 AM to 8 PM ET) to request a form by mail - **Download** the form from MerckHelps.com - **Contact** your healthcare provider's office, as they may have forms available ### Step 2: Complete Your Information Fill out **all sections** of the enrollment form completely.
