Mebendazole is an anthelmintic (deworming) medicine used to treat common intestinal worm infections. It is important to know that mebendazole is not a low-cost generic in the United States. As of 2026 there is no FDA-approved generic mebendazole here. The only FDA-approved mebendazole product is the brand Emverm, and as a single-source brand with no generic competition its cash price is very high. Rx.com checks prices across 60,000+ U.S. pharmacies, and Emverm also has a manufacturer savings program and a patient assistance program that may help with cost. Enter your ZIP above to see today's price on mebendazole (Emverm) at pharmacies near you, and read on for ways to lower what you pay.
What is mebendazole and how does it work?
Mebendazole is an anthelmintic (antiparasitic) medicine in the benzimidazole class. It is FDA-approved to treat intestinal worm (helminth) infections in adults and children 2 years and older. It is commonly prescribed for pinworm, whipworm, roundworm, and hookworm infections, including cases where more than one type of worm is present. In the United States, mebendazole is sold under the brand name Emverm, which is the only FDA-approved mebendazole product. There is currently no FDA-approved generic mebendazole in the U.S. An older brand, Vermox, was discontinued in the U.S. in 2011 and is no longer marketed here, though you may still see its name in reference materials.
Mebendazole works by stopping the worms from absorbing glucose (sugar), which they need for energy. Without it, the worms lose their energy supply and die, and the body then clears them naturally. It is also used for certain other helminth infections when a provider directs. Always take it exactly as your provider or pharmacist directs.
Mebendazole cost and savings without insurance
Mebendazole is unusual for a decades-old medicine. Because there is no FDA-approved generic in the United States and only one brand (Emverm) is available, it is a single-source brand-name drug and its cash price is very high, unlike most common generics. There is no cheaper generic version to switch to. Prices can still vary by pharmacy, and many pharmacies do not keep it in stock and may need to special-order it, so it is worth comparing and calling ahead. Rx.com compares prices across 60,000+ pharmacies. Enter your ZIP above to see today's price near you.
Because the cash price is high, the manufacturer programs are often the most meaningful way to lower cost. Emverm offers a manufacturer savings program, and a patient assistance program may provide the medication at no cost to qualifying patients. Eligibility rules and terms vary, and the savings program is generally not valid for people covered by Medicare, Medicaid, or other government programs. Check the official page for current details: Emverm savings program. Ask your provider or pharmacist whether a different but related medicine might be appropriate for your infection. This is general information, not medical or financial advice.
Mebendazole vs. other deworming medicines
Mebendazole is one of several medicines used to treat worm infections, and the right choice depends on which parasite is involved and your provider's judgment. Because U.S. mebendazole (Emverm) has no generic and a very high price, providers sometimes consider related options depending on the diagnosis:
- Albendazole — another benzimidazole anthelmintic used for a broad range of worm infections.
- Pyrantel pamoate — an over-the-counter deworming option often used for pinworm.
- Ivermectin — used for certain parasitic infections.
- Praziquantel — used mainly for tapeworm and fluke infections.
In the U.S., mebendazole is only available as the brand Emverm; there is no generic to substitute. Ask your provider or pharmacist which medicine and form is right for your situation and your budget.
Safety and side effects
Mebendazole has no boxed warning and is generally well tolerated at standard short-course doses. The most common side effects include abdominal pain, diarrhea, nausea, gas, and headache. You should not take it if you are allergic to mebendazole. It is not recommended during pregnancy (especially the first trimester), and it should be used with caution while breastfeeding.
Rare but serious risks have been reported, mostly with high doses or prolonged use. These include bone marrow suppression (low white blood cell counts), liver enzyme elevations or hepatitis, serious skin reactions (such as Stevens-Johnson syndrome), allergic swelling (angioedema), and rare seizures. Because of this, providers may monitor blood counts and liver function during extended treatment. Concurrent use with metronidazole should be avoided. This is not medical advice — talk with your provider or pharmacist about your health history and any other medicines you take, and seek care promptly if you have a severe reaction.
