Quick Facts Scannable
- Ivermectin is used to treat various parasitic infections in humans.
- It works by paralyzing and killing parasites, preventing their reproduction.
- Available forms include tablets, creams, and lotions.
- Common side effects: nausea, dizziness, and fatigue.
- Severe reactions are rare but can include neurological effects.

What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to glutamate-gated chloride channels in the nervous system of parasites. This causes increased permeability to chloride ions, leading to paralysis and death of the parasites, thereby effectively eliminating the infections they cause. Its selective toxicity to parasites makes it a favorable choice for treating specific parasitic conditions in humans.
Indications / Uses
Ivermectin is primarily approved for treating certain parasitic infections, including:
- Strongyloidiasis, an intestinal infection caused by Strongyloides stercoralis
- Onchocerciasis, also known as river blindness
- Scabies and lice infestations (topical forms)
Off-label, ivermectin has been explored for other uses, such as treating rosacea. However, these applications should only be considered under strict medical supervision due to variability in individual response and potential side effects.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets, creams, and lotions. The dosing of ivermectin depends significantly on the specific condition being treated, the patient’s weight, age, and overall health status. Typical treatment for systemic infections involves a single oral dose adjusted to body weight. For topical applications, formulations are applied directly to affected areas. It is crucial to adhere strictly to prescribed doses and not attempt self-dosing adjustments.
How to Take It Correctly Step-by-Step
For oral ivermectin:
- Take the dose on an empty stomach with a full glass of water.
- If you miss a dose, take it as soon as possible, unless it\’s near the time for the next dose. Do not double up.
Storage tips:
- Store at room temperature away from moisture and heat.
- Keep medications out of reach of children.
Avoid common mistakes such as sharing your medication or mixing it with alcohol, which may exacerbate side effects.

- Pregnant or breastfeeding women: Consult your healthcare provider to weigh risks and benefits.
- Elderly patients may require adjusted dosing based on kidney or liver function.
- Individuals with severe hepatic impairment should use caution, given potential drug concentration variances.
Drug, Food, and Supplement Interactions
Ivermectin can interact with several other medications, potentially altering its effectiveness or increasing side effects. For instance, interactions with medications like warfarin can affect blood clotting. Alcohol may exacerbate side effects such as dizziness or nausea.
Patients should inform their healthcare provider about all medications and supplements they are taking to avoid harmful interactions.
Price & Availability
