Quick Facts
- Primarily used to treat parasitic infections such as onchocerciasis and strongyloidiasis in humans.
- Mechanism of action involves paralyzing and killing parasites through increased neural transmission of the neurotransmitter gamma-aminobutyric acid (GABA).
- Available in tablet form, topical formulations, and injectables (for veterinary use).
- Common side effects include nausea, dizziness, and diarrhea.
- Serious side effects may include seizures or severe skin reactions; always seek medical advice if these occur.
- Interactions are possible with other medications affecting liver enzymes.
- Not recommended for pregnant or breastfeeding women unless essential.
- Seek urgent medical help for any allergic reactions or severe side effects.
What It Is and How It Works
Ivermectin is an anti-parasitic agent used to treat several types of parasitic infections. It works by binding to invertebrate muscle and nerve cells of organisms, which results in increased permeability of the cell membrane to chloride ions. This leads to paralysis and death of the parasite. In humans, ivermectin is selective for parasites due to specific channels that are absent or less prevalent in human cells.
Indications / Uses
The primary approved uses of ivermectin in humans are for the treatment of parasitic infections such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis (a type of intestinal parasitic disease)
In veterinary medicine, it is used for deworming and parasitic prevention in both pets and livestock. There are discussions about its off-label use in viral infections, but these uses should only be considered in clinical trial settings with professional supervision, as they are not officially approved due to limited and context-specific evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Oral tablets for human use
- Topical creams or lotions (for skin conditions like rosacea or lice)
- Injectable solutions (primarily for veterinary use)
The typical dosing of ivermectin for parasitic infections is based on body weight and the specifics of the infection being treated. For example, the dosage might be 200 mcg/kg given orally as a single dose for certain infections in humans. Patients should follow the dosing schedule prescribed by their healthcare provider, considering factors like weight, liver/kidney function, and other health conditions.
How to Take It Correctly Step-by-Step
When prescribed ivermectin, consider the following instructions:
- Take ivermectin 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, but skip it if it\’s almost time for your next dose. Do not double up doses.
- Store ivermectin at room temperature, away from moisture and heat.
- Avoid consuming alcohol during treatment, as it may increase certain side effects.
Side Effects Common to Serious
Common Side Effects
Common side effects may include:
- Dizziness
- Nausea
- Diarrhea
Less Common Side Effects
Some patients may experience:
- Headache
- Fatigue
Serious or Rare Side Effects
Serious side effects require immediate medical attention:
- Allergic reactions (rash, itching, swelling, severe dizziness, trouble breathing)
- Neurological effects (seizures, ataxia)
Contraindications & Precautions
Individuals should avoid ivermectin if they have:
- Known hypersensitivity to ivermectin or any component of the formulation
- Severe liver impairment without a healthcare provider’s consultation
Special precautions are needed for:
- Pregnant or breastfeeding women, as safety is not well established
- Elderly patients, who may have agerelated decrease in body functions
- Individuals with concurrent infections or inflammation
Drug, Food, and Supplement Interactions
Because ivermectin is metabolized in the liver, interactions may occur with other drugs that affect liver enzymes. Examples include:
- Certain anticonvulsants and medications that induce cytochrome P450 enzymes
- Some prescription medications and supplements; always inform your healthcare provider of all concomitant medications and supplements.
Price & Availability
The price of ivermectin can depend on several factors including the brand, form, dosage, and pharmacy location. While exact pricing data is not provided, general considerations are shown below:
| Factor | Considerations |
