Quick Facts

• Used to treat parasitic infections such as strongyloidiasis and onchocerciasis.
• Works by paralyzing and killing parasites.
• Available in tablet and topical forms; some forms are prescription-only.
• Side effects can include nausea, dizziness, and skin reactions.
• Potential interaction with other medications, supplements, and alcohol.
• Cautious use advised in children, pregnant or breastfeeding women, and the elderly.

• Seek immediate medical help for symptoms like rash, difficulty breathing, or swelling.

What It Is and How It Works

Ivermectin belongs to a class of medications called anthelmintics. It functions by binding to the parasite\’s nerve and muscle cells, causing paralysis and eventual death. This mechanism effectively treats infections by eliminating the parasites residing in or on the host.

Technically, it increases the permeability of the parasite\’s cell membrane to chloride ions, resulting in paralysis. While this is straightforward in its primary targeted organisms, the question of its effect on humans in other areas remains an area of continual investigation.

Indications / Uses

Ivermectin\’s primary FDA-approved uses include the treatment of:

• Strongyloidiasis: A parasitic disease affecting the intestines.
• Onchocerciasis: Also known as river blindness, caused by worms spread through blackfly bites.

Off-label, ivermectin has been explored for conditions ranging from scabies to potential viral infections. However, such uses should be pursued only under medical supervision due to the varying evidence supporting them.

Dosage Forms and Typical Dosing Considerations

Ivermectin is commonly available in oral tablet form and as a topical preparation. The oral form is usually prescribed for internal parasite infections, whereas topical forms are often used for skin conditions like rosacea.

Dosage may depend on factors like age, weight, existing health conditions, and specific infection treated. For instance, treatment of onchocerciasis involves a dose based on body weight, typically given only once, whereas other conditions might require repeated doses.

It is crucial to adhere to prescribed dosing instructions, as alterations can lead to ineffective treatment or increased risk of side effects.

How to Take It Correctly Step-by-Step

• Take oral ivermectin on an empty stomach, with water, unless directed otherwise.
• Do not eat or drink (except water) 1 hour before and 2 hours after taking it.
• If you miss a dose, take it as soon as possible unless it\’s almost time for the next dose. Do not double up.
• Follow all instructions on storage; typically, store it in a cool, dry place.
• Avoid alcohol, and discuss all supplements with your healthcare provider.
