Your prescription will always include specific instructions from your licensed provider, and those instructions — not general information — should guide how you take your medication. The details below explain the general labeled administration guidance for ivermectin and mebendazole so you understand the reasoning behind common instructions, but your individual regimen is set by your provider based on your evaluation.

Ivermectin (Stromectol): labeled administration

The FDA-approved label states that Stromectol should be taken on an empty stomach with water. This matters because clinical pharmacokinetic data cited in the label show that taking ivermectin with a high-fat meal can substantially increase how much of the drug is absorbed, which changes its effect. Your provider determines your specific dose and schedule — see the ivermectin medication page for more background.

Mebendazole (Emverm): labeled administration

The FDA-approved label for Emverm states the chewable tablet may be chewed, swallowed, or crushed and mixed with food, and that no special preparation such as fasting or purging is required. Dosing frequency depends on the specific infection being treated and is set by the prescriber. Learn more on the mebendazole medication page.

Table: general administration guidance from FDA labeling

| Medication | Food instructions | Administration form | |---|---|---| | Ivermectin (Stromectol) | Empty stomach, with water | Tablet, swallowed | | Mebendazole (Emverm) | With or without food | Chewable tablet — chew, swallow, or crush into food |

General principles for taking any prescribed medication

• Take the exact dose and schedule your provider specifies — do not adjust based on general information you read online
• Store medication as directed, typically at room temperature and away from moisture, and out of reach of children
• Keep track of when you took each dose, especially for multi-day mebendazole courses
• Do not share your prescription with anyone else, since dosing is individualized

If you miss a dose or have questions

Contact your provider or pharmacist rather than guessing. Because these medications are prescribed for specific, labeled uses with defined dosing schedules, an unplanned change can affect how well the treatment works or increase side-effect risk. You can review the overall process, including how to reach your care team, at how it works and check pricing for any follow-up visits.

After you finish treatment

Some conditions call for follow-up testing or a repeat course, which your provider will explain based on your specific diagnosis. If symptoms persist or new symptoms appear after finishing your course, reach out rather than waiting, and review who should not take these medications if you're unsure whether a symptom needs attention. Keeping the original prescription label and instructions on hand can also make it easier to answer a pharmacist's or provider's questions accurately during any follow-up conversation.

Related questions

Should I take ivermectin with food?

No — the FDA label specifically instructs taking Stromectol on an empty stomach with water, since food (especially high-fat meals) can significantly increase how much of the drug your body absorbs. Follow your provider's exact instructions, since your dose was calculated with this in mind.

Can I crush my mebendazole tablet?

Yes. The Emverm label states the chewable tablet may be chewed, swallowed whole, or crushed and mixed with food, so there is flexibility in how you take it. Choose whichever method is easiest for you unless your provider specifies otherwise.

What should I do if I miss a dose?

Contact your provider or pharmacist for guidance specific to your prescription rather than doubling up or guessing. This is especially important for multi-day mebendazole courses, where timing affects the treatment schedule.

Do I need to repeat treatment after finishing my course?

It depends on the specific infection and your provider's assessment; some conditions call for repeat dosing or follow-up testing. Your provider will let you know if and when a second course or check-in is needed based on your case.
