What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to the avermectins class of medications. It works by binding to the invertebrate nerve and muscle cells, causing paralysis and death of the parasites. It is primarily used to treat conditions caused by parasitic worms in humans.
More technically, ivermectin binds with high affinity to certain chloride channels found in neural and muscle cells—leading to hyperpolarization of nerves and muscles which ultimately results in paralysis of the parasite.
Indications / Uses
Primarily, ivermectin is approved for the treatment of onchocerciasis (\”river blindness\”) and strongyloidiasis. It is also used off-label for the treatment of other parasitic infestations, such as lice and scabies. Off-label uses should only be pursued under the supervision of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin can be found in several forms, including tablets, topical creams, and injectables. The dosing of ivermectin depends on the condition being treated, the patient’s weight, and the specific formulation. It is crucial for patients to follow their healthcare provider\’s instructions closely.
For some parasitic conditions, a single oral dose is sufficient, while others may require repeated doses. Special considerations are made for those with compromised liver function, and adjustments may be necessary for pediatric and elderly populations.
How to Take It Correctly Step-by-Step
To ensure correct administration of ivermectin:
- Take oral tablets on an empty stomach with water unless otherwise advised by a physician.
- If you miss a dose, take it as soon as you remember but do not double up on the next dose.
- Store at room temperature away from moisture and heat.
- Avoid alcohol, which may increase the risk of side effects.
Always ask your pharmacist if you are unsure about any instructions provided on the medication label.
