What It Is and How It Works
Ivermectin is an antiparasitic agent, which belongs to the class of drugs known as avermectins. It works by binding to invertebrate muscle and nerve cells, increasing the permeability of the cell membrane to chloride ions, which leads to paralysis and death of the parasites. In humans, this mechanism selectively targets parasites without affecting human cells significantly.
Indications / Uses
Ivermectin is primarily approved for treating specific parasitic infections such as onchocerciasis, also known as river blindness, and intestinal strongyloidiasis. It is also effective in treating scabies and lice.
Off-label, ivermectin has been explored for various other conditions, though these uses should only be considered under medical supervision due to potential safety and efficacy concerns.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in oral tablet form for human use. Typical dosing varies based on the specific condition being treated, the patient\’s weight, and other health considerations. It is crucial to follow the prescribed dosage given by a healthcare provider.
Special populations, like patients with liver or kidney conditions, may require adjusted dosing. Pregnant or breastfeeding women should exercise caution and consult their healthcare provider before use.
How to Take It Correctly Step-by-Step
Ivermectin tablets should be taken on an empty stomach with a full glass of water unless directed otherwise by a physician. Adherence to the dosing schedule is essential for effectiveness. In case a dose is missed, it should be taken as soon as remembered unless it is close to the time of the next dose.
Store ivermectin at room temperature away from moisture and heat.
