What It Is and How It Works
Ivermectin is an antiparasitic medication that disrupts nerve and muscle function in parasites, leading to their paralysis and death. It binds to specific invertebrate nerve and muscle cell receptors, causing increased permeability of cell membranes to chloride ions. This effect is toxic to numerous parasites but has limited impact on humans due to differences in these cell types.
Indications / Uses
Injectable ivermectin is primarily used for treating parasitic infections in animals, such as heartworm in dogs or gastrointestinal worms in cattle. In humans, ivermectin is more commonly prescribed in an oral form for conditions like strongyloidiasis and onchocerciasis. Though there have been discussions about other uses, these should only be undertaken with medical supervision and where evidence supports efficacy and safety.
Dosage Forms and Typical Dosing Considerations
For humans, ivermectin is usually taken orally, but the injectable form is sometimes considered off-label for specific conditions. The dosing is highly individualized, depending on factors such as age, weight, and renal function. It\’s crucial to follow the dosing instructions provided by a healthcare professional, as improper use can lead to serious side effects or ineffective treatment.
How to Take It Correctly Step-by-Step
If prescribed, ensure you follow these general guidelines:
- Administer under the supervision of a healthcare professional.
- Do not mix with other medications without advice.
- Adhere to the prescribed schedule.
- Store at temperatures specified by the pharmacist or packaging instructions.
- Report missed doses to your healthcare provider; do not double doses.
