Ivermectin is not suitable for every condition, and its safety depends on how it is used. In the United States, oral ivermectin tablets are approved for specific parasitic infections, including intestinal strongyloidiasis and onchocerciasis. Different formulations may have different approved uses.

Questions to ask before taking ivermectin include whether the medication is appropriate for your condition, what side effects to expect, and which precautions to follow. A healthcare provider can assess possible interactions and explain how to follow the prescribed instructions. The U.S. Food and Drug Administration (FDA) also warns against using veterinary ivermectin products in humans. Read the FDA guidance on ivermectin for more information.

10 Questions to Ask Your Doctor Before Taking Ivermectin

1. Why Has Ivermectin Been Recommended for My Condition?

Start by asking your doctor why ivermectin is being considered for your particular diagnosis.

Your healthcare provider can explain the condition being treated, how the medication works against the relevant parasite, and whether other treatment options may be appropriate.

Understanding the reason for treatment helps you distinguish between established medical uses and uses that may lack sufficient evidence.

2. Is Ivermectin Appropriate for My Medical History?

Your medical history may influence whether a medication is suitable for you.

Tell your doctor about any existing medical conditions, previous reactions to medicines, allergies, and other relevant health concerns. Ask whether any of these factors could affect your treatment or require additional monitoring.

Never assume that a medication prescribed to someone else will be suitable for you.

3. What Side Effects Should I Know About?

Ask your doctor which side effects may occur and which symptoms require medical attention.

Reported side effects of oral ivermectin can include dizziness, nausea, diarrhoea, and abdominal discomfort. The effects you may experience depend on several factors, including the condition being treated.

Seek urgent medical attention if you experience severe confusion, seizures, difficulty breathing, or another serious reaction. Your doctor or pharmacist can explain the warning signs relevant to your circumstances.

4. Could Ivermectin Interact With My Other Medications?

Drug interactions can affect how medicines work or increase the risk of adverse effects.

Give your healthcare provider a complete list of your current prescription medicines, over-the-counter products, vitamins, and supplements. Ask whether any of them could interact with ivermectin.

For example, the prescribing information reports rare increases in INR in patients taking warfarin with ivermectin. If you use a blood thinner, make sure your prescriber knows about it.

Do not stop or change any existing medication without appropriate medical advice.

5. What Instructions Should I Follow When Taking Ivermectin?

Ask your doctor or pharmacist to explain the exact instructions for your prescription.

You should understand the prescribed dose, timing, duration, and any food-related instructions. These details can vary depending on the infection, formulation, and individual circumstances.

Do not increase the dose, take additional tablets, or repeat treatment without medical guidance. Taking more than prescribed can cause serious harm.

6. What Should I Do If I Miss a Dose?

Ask your healthcare provider what to do if you forget a scheduled dose.

The appropriate response can depend on the prescribed treatment schedule and the condition being treated. Do not automatically double your next dose to compensate for a missed one.

If you are unsure what to do, contact your pharmacist or prescribing clinician for instructions specific to your prescription.

7. Is Ivermectin Suitable During Pregnancy or Breastfeeding?

If you are pregnant, planning a pregnancy, or breastfeeding, discuss this with your healthcare provider before starting treatment.

The available safety information and recommendations may differ depending on the circumstances and the condition being treated. Your clinician can assess the potential benefits and risks and explain whether an alternative treatment should be considered.

Do not start or discontinue a prescribed medication during pregnancy or breastfeeding without professional guidance.

8. How Will We Know Whether the Treatment Is Working?

Ask how your doctor will assess your response to treatment.

Depending on the infection, follow-up may involve reviewing symptoms, conducting laboratory tests, or arranging additional examinations. Some parasitic infections require continued monitoring even after treatment.

Find out when you should expect a follow-up appointment and what to do if your symptoms persist or worsen.

9. Are There Any Activities or Precautions I Should Consider?

Ask whether your medication or underlying condition could affect your daily activities.

Ivermectin may cause dizziness in some people. If you experience this effect, avoid driving or operating machinery until you are safe to do so.

Your doctor can also explain any other precautions that apply to your condition, treatment, or other medications.

10. Where Should I Obtain My Medication and Reliable Information?

Ask your healthcare provider or pharmacist how to obtain the prescribed medicine from a legitimate, regulated source.

Check that the medication is intended for human use, that the product matches your prescription, and that the packaging and instructions are appropriate for your country.

Never substitute veterinary formulations for human medication. Veterinary products may have different concentrations and ingredients, and they have not been evaluated for safe use in humans in the same way as human medicines.

What Should You Tell Your Doctor Before Taking Ivermectin?

To help your healthcare provider assess your treatment, prepare the following information for your appointment:

• Your current symptoms and when they started.
• Any diagnosis or test results relevant to your condition.
• A list of prescription medicines, over-the-counter products, and supplements you use.
• Your known allergies and any previous medication reactions.
• Relevant medical conditions and your pregnancy or breastfeeding status, where applicable.
• Any previous treatment you have received for the same condition.

Providing complete and accurate information helps your clinician make an informed treatment decision.
