What It Is and How It Works
Ivermectin is primarily an antiparasitic medication belonging to the avermectin class of drugs. It works by binding to certain channels in parasites\’ cell membranes, causing an increase in the permeability of these cells to chloride ions. This leads to paralysis and eventually the death of the parasites. In technical terms, it targets glutamate-gated chloride channels and perhaps GABA-gated chloride channels in nerve and muscle cells of the invertebrates.
Indications / Uses
Ivermectin is predominantly used to treat parasitic worm infections, specifically strongyloidiasis (threadworm) and onchocerciasis (river blindness) in humans. It is also utilized in veterinary medicine to prevent and treat heartworm, intestinal worms, and mites in animals. While its use as an antiparasitic is well-established, ivermectin has been explored for off-label applications, such as potential antiviral properties, though such uses require more scientific validation and should only be considered under the supervision of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets, topical preparations, and injectable solutions for veterinary use. Human prescription forms are typically in tablet form. The medication is dosed based on the patient’s weight, the specific infection being treated, and other individual health factors. Adjustments may be necessary for patients with liver dysfunction or coexisting medical conditions. The dosing must strictly follow a healthcare provider’s instructions.
How to Take It Correctly Step-by-Step
When taking ivermectin tablets, it is usually recommended to do so on an empty stomach with water, approximately one hour before breakfast. It\’s important to follow the prescribed frequency and duration. If a dose is missed, take it as soon as possible unless it\’s close to the time for the next dose. Do not double doses. Store at room temperature away from moisture and heat. Avoid consuming grapefruit or grapefruit juice as it may increase ivermectin\’s side effects.
Side Effects Common to Serious
Common Side Effects
These may include headache, dizziness, nausea, fatigue, or gastrointestinal upset. Patients often tolerate these side effects well, but they should consult their doctor if side effects persist.
Less Common Side Effects
May include skin rashes, itching, and mild visual disturbances. Monitoring is suggested for such occurrences.
Serious or Rare Side Effects
Severe hypersensitivity reactions, seizures, and liver problems are serious side effects. If symptoms like difficulty breathing, severe rash, or jaundice occur, seek emergency medical attention immediately.
Contraindications & Precautions
Individuals with known hypersensitivity to ivermectin should avoid its use. It is advised to use caution in patients with liver disease, during pregnancy, or while breastfeeding, as well as in pediatric populations due to limited data. An assessment from a healthcare provider is crucial before starting treatment.
Drug, Food, and Supplement Interactions
Ivermectin may interact with several medications, such as warfarin, which can affect blood-clotting processes, medications metabolized by the liver, and certain antifungal drugs. Further, alcohol consumption should be minimized due to potential enhanced side effects. Patients should provide a full list of all medications, supplements, and food types to their healthcare provider to prevent adverse interactions.
Price & Availability
The cost and availability of ivermectin can vary greatly depending on the country, generic or brand status, dosage required, and health insurance coverage. Supply issues can also affect pharmacy stock levels.
