What It Is and How It Works

Ivermectin is an antiparasitic agent that falls into the class of drugs known as avermectins. It works by interfering with the parasite\’s nervous system, effectively leading to paralysis and death of these organisms. This action is highly selective to parasites due to their specific nervous system architecture, making ivermectin safe for human use in treating specific conditions.

Technically, it binds to glutamate-gated chloride channels which are vital for neurotransmission in the parasites, making it highly effective against a variety of external and internal parasites.

Indications / Uses

Ivermectin is primarily approved for treating certain parasitic infections, such as:

• Onchocerciasis (River Blindness): A parasitic worm infection transmitted through blackfly bites.
• Strongyloidiasis: An intestinal infection caused by a type of roundworm.

It is sometimes used off-label for other parasitic conditions in consultation with a healthcare provider, but such uses require careful supervision due to the potential for side effects and interactions.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in oral tablet forms, commonly in 3 mg, 6 mg, and 12 mg strengths. It is also available as a topical cream or lotion at different concentrations for conditions such as rosacea or head lice. The dosing varies significantly based on the condition being treated, patient weight, age, and other health factors. Special considerations for dosing include:

• Liver Impairment: Dosing adjustments may be necessary as ivermectin is metabolized in the liver.
• Pediatric and Elderly Patients: Use caution due to potential differences in drug metabolism and sensitivity.

Specific dosing should always be followed according to a prescription and healthcare provider instructions.

How to Take It Correctly Step-by-Step

• Take ivermectin on an empty stomach with water, at least an hour before meals.
• If you miss a dose, take it as soon as you remember unless it’s almost time for the next dose. Do not double up doses.
• Store at room temperature and keep it out of reach from children.
• Do not share your medication with others, even if they have similar symptoms.
• Avoid alcohol as it may increase the risk of certain side effects.
