Famotidine is prescribed to reduce stomach acid production and treat acid reflux, GERD, and ulcers. It is sold under the brand name Pepcid and is available as the generic Famotidine. A standard supply is 30 20mg.
Pharmacy pricing is not regulated in the United States, so retailers set their own cash prices. Large retailers like Walmart and Costco typically offer lower prices on generics because they use prescriptions as a traffic driver. Chain pharmacies like CVS and Walgreens tend to charge significantly more.
Proton pump inhibitors (PPIs) and H2 blockers are widely used. Generic versions are available and usually cost under $10/month at cash prices.
Famotidine belongs to a class of medications called H2 receptor blockers. It reduces stomach acid production through a different mechanism than a proton pump inhibitor (PPI), generally works faster but for a shorter duration, and is available both over-the-counter and by prescription depending on the strength. It's sometimes used short-term for occasional heartburn and sometimes prescribed for longer-term acid-related conditions, and unlike a PPI, it doesn't require the body to build up an effect over several days — some patients use it specifically for that faster onset when quick relief matters more than the potency of a proton pump inhibitor.
Shop around. The cheapest pharmacy (Walmart at $4.00) charges significantly less than the most expensive option ($10.50). A quick call can save you real money.
Ask for the generic. If your doctor prescribed the brand-name Pepcid, ask your pharmacist whether the generic Famotidine is available. In most states, pharmacists can substitute a generic unless the prescriber writes 'dispense as written.'
Use a discount card. Services like GoodRx, SingleCare, and WellRx can sometimes negotiate prices lower than retail cash. The estimated GoodRx low for Famotidine is around $3.00.
Famotidine is an inexpensive generic sold over-the-counter as well as by prescription, so there's no manufacturer copay card program tied to it — comparing OTC pricing against the prescription cash prices above is often the fastest way to find the lowest cost.
Coverage depends on your specific plan and formulary. Most acid reflux medications are covered under standard health insurance, typically in Tier 1 or Tier 2. If your copay is higher than the cash price above, it may be cheaper to pay out of pocket — ask your pharmacist to compare. Prior authorization is uncommon for famotidine, though some plans decline to cover it at all at prescription strength once it's available over-the-counter — worth confirming directly with your plan.

Yes — the generic Famotidine is available and bioequivalent to Pepcid. Ask your pharmacist to dispense the generic to save money.
What if my insurance doesn't cover Famotidine at all?
Ask your prescriber whether a covered therapeutic alternative in the same drug class exists, or ask your pharmacist about a formulary exception or medical-necessity appeal — some plans will cover an otherwise-excluded drug once that documentation is on file. In the meantime, the cash and discount-card pricing shown above is usually the fastest fallback.
Does a 90-day supply of Famotidine cost less than three 30-day fills?
Often, yes — many pharmacies and insurance plans price a 90-day fill at a lower effective per-dose cost than separate 30-day fills, and some mail-order pharmacy benefits are built specifically around 90-day supplies. Ask your pharmacist or insurer whether a 90-day option is available for this medication before assuming the count shown above is your only choice.
