Quick Facts
- Ivermectin is used primarily to treat parasitic infections.
- It works by interfering with the nerve and muscle functions of parasites.
- Common forms include oral tablets, topical lotions, and creams.
- Typically prescribed for conditions like head lice, scabies, and river blindness.
- Common side effects can include dizziness, nausea, or mild skin rash.
- Potential interactions with drugs such as anticoagulants or other anti-parasitic medications should be considered.

- If you experience severe symptoms such as difficulty breathing, seek urgent medical care.
What It Is and How It Works
Ivermectin is an anti-parasitic agent that disrupts nerve and muscle functions in certain parasites, leading to their paralysis and eventual death. It belongs to a class of medications known as macrocyclic lactones and is derived from the bacterium Streptomyces avermitilis. While the precise mechanism in human parasitic diseases isn\’t fully understood, it is believed to bind to chloride channels that are more prevalent in parasites, with less effect on the host cell membranes, thereby ensuring its action is selective towards parasites.
Indications / Uses
Ivermectin is FDA-approved for treating several parasitic diseases:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal threadworm)
- Scabies
- Head lice
Additionally, ivermectin may be used off-label under healthcare provider supervision for other infections as deemed necessary. It\’s important to note that the safety and efficacy of off-label uses vary and require professional guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations, which are chosen based on the condition being treated:
- Oral tablets: Commonly used in the treatment of parasitic worm infections.
- Topical creams and lotions: Used primarily for skin conditions like scabies and head lice.
Dosing is highly dependent on the specific condition, the patient\’s weight, and other individual factors like liver function. Therefore, following the prescription and advice from a healthcare provider is crucial.
How to Take It Correctly Step-by-Step
Here are some general guidelines for taking ivermectin safely:
- Take oral ivermectin on an empty stomach with water unless directed otherwise.
