Medicare's Coverage of Dimenhydrinate

Medicare Part B does not cover dimenhydrinate as a prescription medication. However, dimenhydrinate is available over-the-counter under brand names like Dramamine, and Medicare Part D prescription drug plans may cover it if your doctor writes a prescription for it — though most people buy it without a prescription at a pharmacy or grocery store.

The coverage question matters because the out-of-pocket cost differs sharply depending on how you obtain it. If you buy dimenhydrinate over-the-counter on your own, Medicare pays nothing and you pay the full retail price, usually between $5 and $15 for a package. If your doctor prescribes it and your Part D plan covers it, you may pay only a copay — typically $1 to $5 — depending on your specific plan.

Whether your Part D plan will cover a prescription for dimenhydrinate depends on that plan's formulary, which is the list of drugs the plan will pay for. Not all Part D plans include dimenhydrinate, and coverage rules change yearly.

Key Takeaways

  • Dimenhydrinate is sold over-the-counter and Medicare Part B does not cover it, but some Part D prescription drug plans may cover it if prescribed by a doctor.
  • Your Part D plan's formulary determines whether a prescription for dimenhydrinate is covered, and this list changes each year.
  • You can check your specific plan's coverage by calling the plan directly, logging into your plan's website, or reviewing your plan documents.
  • If your Part D plan does not cover dimenhydrinate, buying it over-the-counter without a prescription is usually cheaper than paying out-of-pocket for a prescription.

How to Check Your Part D Plan's Formulary

Your Part D plan mails you a formulary booklet each year, usually in October or November. This booklet lists every drug your plan covers, the copay amount for each tier, and any restrictions. Dimenhydrinate, if covered, will appear in the antihistamine or motion sickness section.

You can also check your plan's website directly. Log in with your Medicare number and search for "dimenhydrinate" in the drug search tool. The result will tell you whether it is covered, what your copay would be, and whether your doctor needs to get prior approval before prescribing it.

If you do not have internet access or prefer to speak with someone, call the customer service number on the back of your Medicare card. Have your plan name and member ID ready. A representative can tell you in a few minutes whether dimenhydrinate is on your formulary and what you would pay.

When a Doctor Might Prescribe Dimenhydrinate

Dimenhydrinate is an antihistamine used to prevent and treat nausea, vomiting, and dizziness caused by motion sickness, inner ear problems, or vertigo. A doctor may prescribe it instead of recommending over-the-counter use if you need a specific dose, if you have other medications that interact with over-the-counter versions, or if your insurance coverage makes the prescription cheaper than buying it yourself.

Some seniors find that a prescription allows them to use a pill organizer or have the pharmacy pre-sort doses, which can make it easier to take on schedule. Others prefer the prescription route because their copay is lower than the retail price.

What to Do If Your Plan Does Not Cover It

If your Part D plan does not cover dimenhydrinate, you have several options. The simplest is to buy it over-the-counter at any pharmacy, grocery store, or online retailer. Dimenhydrinate tablets are inexpensive and widely available under the Dramamine brand and many generic versions.

You can also ask your doctor whether an alternative medication that your plan does cover might work for your condition. Some Part D plans cover other antihistamines or anti-nausea drugs that may be suitable depending on why you need the medication.

If you change your Part D plan during the annual enrollment period (October 15 to December 7 each year), you can choose a plan that does cover dimenhydrinate. Use the Medicare Plan Finder tool on Medicare.gov to compare plans and see which ones include dimenhydrinate on their formulary.

Dimenhydrinate and Other Medicare Coverage

Medicare Part A (hospital insurance) does not cover dimenhydrinate as an outpatient medication, but if you are admitted to a hospital or skilled nursing facility, the facility may provide it as part of your inpatient care at no additional cost to you.

If you have a Medigap policy (supplemental insurance), it does not change your Part D coverage for dimenhydrinate. Medigap policies cover gaps in Part A and Part B, not prescription drugs. If you have a Medicare Advantage plan (Part C) instead of Original Medicare, that plan includes prescription drug coverage, and you would check that plan's formulary the same way you would check a standalone Part D plan.

Frequently Asked Questions

Can I use a GoodRx coupon or discount card for dimenhydrinate if Medicare does not cover it?

Yes. If your Part D plan does not cover dimenhydrinate or if you do not have Part D, you can use a GoodRx coupon, SingleCare, or similar discount programs to reduce the price when you buy it over-the-counter. These coupons often bring the cost down to $3 to $8 per package. You cannot use them at the same time as your Medicare coverage, so use them only when your plan does not cover the drug.

What if my doctor prescribes dimenhydrinate but my plan requires prior approval?

Prior approval means your doctor must contact your Part D plan and get permission before the pharmacy will fill the prescription. Your doctor's office usually handles this request at no cost to you. It typically takes one to three business days. If the plan denies the request, your doctor can appeal or suggest an alternative drug that does not require prior approval.

Does Medicare cover dimenhydrinate patches or other forms besides tablets?

Coverage depends on the form and your specific Part D plan. Tablets are most commonly covered if the plan covers dimenhydrinate at all. Patches, liquids, or injections may have different coverage rules. Check your plan's formulary or call your plan to ask about the specific form your doctor recommends.

Will my Part D coverage of dimenhydrinate change next year?

Yes, Part D formularies change every January 1. A drug covered this year may not be covered next year, or the copay may increase. Review your plan's new formulary when it arrives in the fall, and if dimenhydrinate coverage changes in a way that affects you, consider switching to a different Part D plan during open enrollment.
