What It Is and How It Works
Ivermectin is an antiparasitic agent that works primarily by affecting the nerve and muscle cells of certain parasites. It binds to the glutamate-gated chloride ion channels in the parasite\’s nervous system, causing an increase in the permeability of the cell membrane to chloride ions. This leads to paralysis and death of the parasites, thereby helping eliminate the infection from the body.
Besides its approved use for parasitic infections, ivermectin is being studied and sometimes used off-label for other conditions. However, its efficacy and safety for these uses vary, and it\’s vital to only consider such applications under medical advice.
Indications / Uses
Ivermectin is primarily indicated for the treatment of specific parasitic infections, including:
- Onchocerciasis: Also known as river blindness, caused by the Onchocerca volvulus parasite.
- Strongyloidiasis: An infection with the roundworm Strongyloides stercoralis.
There are additional off-label uses that have arisen, but these should always be considered under the direct guidance of a healthcare provider due to the variability in scientific support and the potential risks involved.
Dosage Forms and Typical Dosing Considerations
Ivermectin is primarily available in tablet form. The dosing of ivermectin depends significantly on the condition being treated, the patient\’s weight, and other health factors.
Typical dosing for parasitic infections might involve a single or periodic dosing regimen. Variations in dosing considerations include:
- Body weight: Weight-based dosing is common to ensure therapeutic effectiveness without toxicity.
- Age and health status: Special caution is advised for children under 15 kg, pregnant women, or individuals with liver conditions.
- Comorbidities and other medications: Conditions like liver disease or concurrent use of other medications, such as certain blood thinners, may affect dosing and safety.
How to Take It Correctly Step-by-Step
- Consult your healthcare provider: Be sure you understand the prescribed regimen.
- Take the prescribed dose: Ivermectin tablets should be taken on an empty stomach with a full glass of water.
- Avoid missing doses: Follow your dosing schedule as prescribed by your healthcare provider.
- Proper storage: Store at room temperature, away from moisture and heat.
- Avoid alcohol: Do not consume alcohol while taking ivermectin, as it can exacerbate side effects.
- Avoid doubling doses: If you miss a dose, take it as soon as you remember unless it\’s near the time for your next dose, in which case, skip the missed dose.
