What It Is and How It Works
Ivermectin is an antiparasitic agent that has been used safely for decades to treat a range of parasitic infections. It works by interfering with the nerve and muscle functions of parasites. This leads to paralysis and eventual death of the parasite, effectively clearing infections from the host organism. Originally designed for veterinary use, it was later approved for human use to combat various parasitic diseases.
Indications / Uses
Primarily, ivermectin is approved for the treatment of certain parasitic infections, including:
- Intestinal strongyloidiasis, a disease caused by the Strongyloides stercoralis parasite.
- Onchocerciasis, also known as river blindness, caused by the Onchocerca volvulus worm.
Off-label, ivermectin has been investigated for other uses, but such use should only occur under the supervision of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, each suited for different types of parasitic infections. The oral tablet form is commonly used for systemic infections. Topical formulations, such as creams and lotions, are available for external use, particularly in treating skin conditions like rosacea.
Typical dosing is influenced by the patient\’s weight, the severity of the infestation, and specific patient-specific factors such as liver and kidney function. It is imperative to follow the prescribing physician\’s dosage instructions and not self-medicate.
How to Take It Correctly Step-by-Step
Taking ivermectin properly involves a few key considerations:
- For oral tablets, take on an empty stomach with water for maximal absorption.
- Adhere to the dosing schedule prescribed by your healthcare provider.
- If you miss a dose, take it as soon as you remember but skip it if it\’s nearly time for your next dose; never double doses.
- Store in a cool, dry place away from light and moisture.
- Avoid alcohol which may increase the risk of side effects.
Do not share your medication with others, even if they have similar symptoms.
