Quick Facts

• Ivermectin is used primarily to treat parasitic infections such as onchocerciasis and strongyloidiasis.
• It works by paralyzing and killing parasites.
• Common forms include oral tablets and topical formulations.
• Common side effects can include dizziness, nausea, and fatigue.
• Ivermectin may interact with blood thinners and other medications.
• Special caution is advised for pregnant and breastfeeding women.
• It is not an approved treatment for COVID-19.
• Seek urgent medical care for symptoms like severe allergic reactions.

What It Is and How It Works

Ivermectin is an antiparasitic agent used primarily for the treatment of infections caused by certain parasitic worms. It operates by binding to the muscle and nerve cells of parasites, which causes paralysis and death. This mechanism helps eliminate the parasites from the body, thus treating the infection.

On a more technical note, ivermectin increases the permeability of cell membranes to chloride ions, leading to hyperpolarization of the nerve or muscle cell, resulting in paralysis and death of the parasite.

Indications / Uses

The primary approved uses of ivermectin include the treatment of parasitic infections such as onchocerciasis (river blindness), strongyloidiasis (intestinal infection), and occasionally for other conditions like scabies and lice. These uses are well-supported in medical guidelines and research.

Ivermectin is sometimes used off-label for other conditions, but such usage should be under the supervision of a healthcare provider as evidence varies by condition and patient population.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in several forms, including oral tablets and topical creams or lotions. The dosage of ivermectin is typically determined by the patient\’s weight, the condition being treated, and other individual health factors. Medication regimens can vary greatly:

• Oral tablets: Generally taken on an empty stomach with water. The dose might repeat depending on the specific condition.
• Topical formulations: Used for skin conditions such as rosacea and sometimes for lice or scabies.

Dosing in special populations, such as in those with liver or kidney impairment, pregnant or breastfeeding individuals, and children, should be carefully managed by a healthcare professional.

How to Take It Correctly Step-by-Step

• Take ivermectin tablets with a full glass of water on an empty stomach, at least one hour before breakfast.
• If using a topical form, apply it to the affected area as instructed by a healthcare provider.
• Do not drink alcohol while taking ivermectin.
• Store at room temperature, away from moisture and heat.
• If a dose is missed, take it as soon as possible unless it is almost time for the next dose; do not double up on doses.

Avoid common mistakes such as taking more than the prescribed dose, sharing medication, or stopping medication abruptly without consulting a healthcare professional.

Healthcare professionals should perform a thorough risk assessment before prescribing ivermectin in these populations.

Drug, Food, and Supplement Interactions

Ivermectin may interact with various medications that influence liver enzymes, such as certain anticoagulants like warfarin. It can also interact with medications affecting mental health, such as benzodiazepines, and certain antifungals like ketoconazole. Alcohol use should be avoided as it can increase the risk of certain side effects.

Patients should inform their healthcare provider of all medications, supplements, and herbal products they are taking to avoid potential interactions.
