Quick Facts
- Ivermectin is used primarily to treat parasitic infections, such as onchocerciasis (river blindness) and strongyloidiasis.
- It works by interfering with the nerve and muscle functions of parasites, leading to their paralysis and death.
- Common forms include oral tablets, typically in strengths of 3 mg, 6 mg, and 12 mg.
- Ivermectin is generally safe but may cause side effects, such as nausea, dizziness, or diarrhea.
- Interaction with other drugs can occur, necessitating a full medication review by a healthcare provider.

- Immediate medical help should be sought if severe allergic reactions or worsening symptoms occur.
What It Is and How It Works
Ivermectin is an antiparasitic agent used to treat infections caused by certain parasites. When ingested, it binds to parts of the parasite\’s nerves and muscles, causing paralysis and eventually death. This action helps remove the parasites from the human body, thereby treating the infection.
Indications / Uses
Ivermectin is primarily approved for treating infections such as:
- Onchocerciasis, also known as river blindness, which is caused by a worm.
- Strongyloidiasis, an intestinal infection caused by a type of roundworm.
Off-label uses might include treatments for other parasitic infections, but these should only be considered under the supervision of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form. The typical dosing depends on factors such as the type of infection, the patient\’s weight, and health condition. It is crucial to follow the dosing schedule prescribed by a healthcare provider. Dosage adjustments might be necessary for patients with liver disease, and caution is advised for use in pregnancy and breastfeeding.
How to Take It Correctly Step-by-Step
When taking ivermectin tablets, follow these steps for optimal efficacy and safety:
- Take the tablet with a full glass of water on an empty stomach, at least one hour before or two hours after a meal.
- If a dose is missed, take it as soon as possible, but if it is almost time for the next dose, skip the missed dose. Do not double the dose.
- Store the medication at room temperature, away from moisture and heat.
- Avoid consuming alcohol, as it may increase the risk of side effects.
