What Medicare covers for famotidine

Medicare Part D (prescription drug coverage) covers famotidine, but whether you pay anything depends on your specific plan and which version you choose. Famotidine is a generic medication that reduces stomach acid, sold as Pepcid AC over-the-counter and in prescription strength under various brand names.

The key difference: over-the-counter famotidine (like Pepcid AC 10 mg tablets) is not covered by Medicare because it is available without a prescription. However, prescription-strength famotidine (20 mg and higher) is covered by most Part D plans. Your out-of-pocket cost depends on which tier your plan places the drug on and whether you have met your deductible.

If your doctor prescribes famotidine rather than recommending the over-the-counter version, your Part D plan will treat it as a covered medication. Many people find that the copay for prescription famotidine is lower than buying over-the-counter versions repeatedly, especially if they take it regularly.

Key Takeaways

  • Over-the-counter famotidine (Pepcid AC) is not covered by Medicare because it does not require a prescription.
  • Prescription-strength famotidine is covered by most Medicare Part D plans, though your copay varies by plan and tier.
  • Your doctor can prescribe famotidine at a strength that qualifies for Part D coverage, which may cost less than buying over-the-counter.
  • You can check your specific plan's formulary (drug list) on Medicare.gov or by calling your plan directly to see the exact copay amount.

How to find out what your plan covers

Every Medicare Part D plan maintains a formulary — a list of covered drugs and the tier (cost level) assigned to each one. Famotidine's tier and your copay amount are listed there. You can search your plan's formulary in two ways.

First, go to Medicare.gov, select "Find Care Providers, Facilities, and Prescription Drugs," then search for your plan by name or scroll through the list. Once you find your plan, you can search for famotidine by name. The formulary will show you the tier, any prior authorization requirements, and the copay amount.

Second, call your Part D plan directly. The phone number is on your insurance card. A representative can tell you the exact copay for famotidine and whether your doctor needs to submit any paperwork before the prescription is filled. This is often faster than searching online if you need an answer the same day.

Prescription strength versus over-the-counter

Over-the-counter famotidine comes in 10 mg tablets, which is the lowest dose. Prescription famotidine starts at 20 mg and goes up to 40 mg. If your doctor prescribes the 20 mg or higher dose, Medicare Part D will cover it as a prescription drug.

Some people take over-the-counter 10 mg famotidine regularly and pay out of pocket. Others ask their doctor to prescribe 20 mg instead, which triggers Part D coverage and often results in a lower total cost despite the copay. This is worth discussing with your doctor, especially if you take famotidine several times a week or daily.

If your plan places famotidine on a high tier with a steep copay, you can ask your doctor whether a different acid-reducer might be on a lower tier. Omeprazole (Prilosec) and pantoprazole (Protonix) are alternatives that may have different coverage or lower copays on your plan.

When Medicare Part D does not cover the cost

You will pay the full cost of famotidine out of pocket in these situations: you have not yet met your Part D deductible (if your plan has one), you have reached the coverage gap (the "donut hole"), or you have exceeded your plan's annual out-of-pocket limit and entered catastrophic coverage.

During the coverage gap, you pay a larger share of the drug cost. However, the Inflation Reduction Act changed this for 2024 and beyond: Medicare now caps your out-of-pocket costs for Part D drugs at $2,000 per year. Once you reach $2,000 in out-of-pocket spending, Medicare pays 80% of the cost and you pay 20% for the rest of the year.

If cost is a barrier, ask your doctor or pharmacist about patient information programs run by the drug manufacturer. Some offer free or reduced-cost medication to people with limited income, regardless of insurance status.

Prior authorization and other restrictions

Most Part D plans cover famotidine without requiring prior authorization, meaning your doctor can write the prescription and the pharmacy will fill it without delay. However, some plans may require your doctor to document that you have tried other treatments first or that you have a specific condition.

Check your plan's formulary or call your plan to ask whether famotidine requires prior authorization. If it does, your doctor's office can submit the paperwork, which usually takes a few business days. Your pharmacist can also check this when you drop off the prescription.

A few plans may limit the quantity you can receive per month or require you to use a mail-order pharmacy for 90-day supplies. These restrictions are listed in your formulary. If a restriction makes the medication inconvenient or expensive, ask your doctor whether an alternative acid-reducer has fewer restrictions on your plan.

Generic versus brand-name famotidine

Generic famotidine is almost always cheaper than brand-name versions like Pepcid. Medicare Part D plans almost always cover generic famotidine on a lower tier, meaning a smaller copay. Brand-name Pepcid, if covered at all, typically costs more out of pocket.

Ask your pharmacist to fill the generic version unless your doctor specifically writes "brand name medically necessary" on the prescription. Generic and brand-name famotidine contain the same active ingredient and work the same way. The difference is price.

What to ask your doctor and pharmacist

Before your doctor writes a prescription for famotidine, ask: "Will you prescribe the strength that Medicare Part D covers?" and "Do I need prior authorization from my insurance?" This ensures the prescription will be covered when you take it to the pharmacy.

When you pick up the prescription, ask your pharmacist: "What is my copay for this medication?" and "Is this the generic version?" If the copay is higher than you expected, ask whether a different acid-reducer has a lower copay on your plan. Your pharmacist can check this in seconds.

If you are taking famotidine regularly and your copay is high, ask your doctor whether a different medication might work as well with lower out-of-pocket cost. Some people benefit from switching to omeprazole or pantoprazole, which may be on a lower tier.

Frequently Asked Questions

Can I use my Medicare Advantage plan to cover famotidine?

Yes. Medicare Advantage plans (Part C) include prescription drug coverage. The rules are the same: over-the-counter famotidine is not covered, but prescription-strength is. Check your plan's formulary on the plan's website or call the plan directly to see the copay amount.

Will Medicare cover famotidine if I buy it over-the-counter at the pharmacy?

No. Medicare Part D only covers medications that are dispensed by prescription. If you buy Pepcid AC or any over-the-counter famotidine without a prescription, Medicare will not reimburse you. Your doctor must write a prescription for the medication to be covered.

What if my plan does not cover famotidine at all?

This is rare, but if it happens, you can ask your doctor to request a coverage exception from your plan. Your doctor submits a letter explaining why famotidine is medically necessary for you. The plan has 72 hours to respond. You can also switch to a different Part D plan during the annual enrollment period (October 15 to December 7) if your current plan's coverage does not meet your needs.

Is prescription famotidine cheaper than buying over-the-counter?

Often yes, especially if you take it regularly. A copay for prescription famotidine might be $5 to $15 per month, while buying over-the-counter Pepcid AC repeatedly can cost $20 to $40 per month. Ask your pharmacist to compare the copay to the over-the-counter price before deciding which to use.

Can I get a 90-day supply of famotidine to save money?

Many Part D plans offer lower copays for 90-day supplies ordered through mail-order pharmacy or picked up at the retail pharmacy. Check your plan's formulary or call your plan to ask whether a 90-day supply is available and what the copay would be. This can reduce your per-month cost significantly.
