Quick Facts
- Ivermectin is used primarily to treat certain parasitic infections.
- It works by binding to parts of the parasite, leading to paralysis and death.
- Common forms include oral tablets, with the 12 mg strength being one of them.
- Onset of action can vary, with some effects seen in days; full results depend on the infection type.
- Common side effects include nausea, dizziness, and diarrhea.
- Severe allergic reactions are rare but require immediate medical attention.
- Patients taking other medications should discuss potential interactions with a healthcare professional.
- Use in special populations such as pregnant or breastfeeding women requires careful assessment by a healthcare provider.
What It Is and How It Works
Ivermectin is classified as an antiparasitic medication. It belongs to a class of drugs known as avermectins, which are known for their ability to combat a variety of parasitic infestations.
The medication works by binding to specific chloride channels in nerve and muscle cells of parasites. This binding increases the permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite. This mechanism is specific to parasite cells as the human central nervous system is protected by a blood-brain barrier.
Indications and Uses
Ivermectin is primarily used to treat infections caused by certain parasites, including:
- Onchocerciasis (river blindness), caused by the worm Onchocerca volvulus.
- Strongyloidiasis of the intestinal tract, caused by the worm Strongyloides stercoralis.
- Scabies, caused by infestation with Sarcoptes scabiei.
- It is also used for lice infestations and lymphatic filariasis in some cases.
While there has been discussion about the use of ivermectin for viral infections like COVID-19, such use is considered off-label in many regions and should only be undertaken under professional medical supervision. Evidence for effectiveness in these conditions remains inconsistent and controversial.
Dosage Forms and Typical Dosing Considerations
Ivermectin for human use is typically available in oral tablet form, with the 12 mg strength being common. The dosing depends on the individual\’s weight, the specific infection being treated, and other factors such as kidney or liver function.
Particular considerations during prescribing include:
- The patient’s body weight as the dosage often requires adjustment according to weight.
- Special populations such as children, elderly patients, and those with significant liver or kidney disease may require modified dosing under professional guidance.
- During pregnancy and breastfeeding, ivermectin\’s use must be carefully evaluated considering potential risks and benefits.
How to Take It Correctly Step-by-Step
To maximize the efficacy and safety of ivermectin:
- Take the tablet orally with a full glass of water on an empty stomach (at least 1 hour before or 2 hours after a meal).
- If you miss a dose, take it as soon as you remember unless it\’s close to the time of your next dose; do not double up doses.
- Store the tablets at room temperature, away from moisture, heat, and direct light.
- Avoid alcohol when taking this medication as it can increase certain side effects.
- Adhere strictly to the prescribed schedule and do not share your medication with others.
