Ivermectin is a medication primarily used to treat parasitic infections in humans and animals. While it has been widely recognized for its effectiveness against conditions like scabies, river blindness (onchocerciasis), and strongyloidiasis, questions remain about how to use it safely and effectively.
In this guide, we explore the safest ways to take Ivermectin by looking at the best time of day for consumption, whether to take it with food, how long its effects last, who should avoid it, and more.
What Is Ivermectin?
Ivermectin is an anti-parasitic drug derived from avermectin, a compound discovered in the 1970s. Approved by the FDA, it has been on the World Health Organization’s List of Essential Medicines for decades. Ivermectin works by paralyzing and killing parasites, stopping them from growing or reproducing.
When Should You Take Ivermectin? Morning vs. Night
Ivermectin Timing
While there is no universally “best” time for taking Ivermectin, studies suggest that the drug may be most effective when taken on an empty stomach, regardless of time. However, certain practitioners recommend taking it in the morning for ease of compliance and observation of potential side effects throughout the day.
Morning Use
- Allows you to monitor for side effects during waking hours.
- Better adherence to a routine.
- Easier to ensure empty stomach status after overnight fasting.
Night Use
- May be convenient for those with a busy daytime schedule.
- Should still be taken at least 1 hour before or 2 hours after eating.
Should You Take Ivermectin With Food?
Ivermectin Food Interaction
Ivermectin is best absorbed when taken on an empty stomach. Food—especially fatty meals—can increase the drug's absorption, potentially leading to higher systemic concentrations. This could increase the risk of side effects without necessarily improving effectiveness.
- ✔️ Recommended: Take on an empty stomach with a full glass of water.
- ❌ Avoid: High-fat meals before or after taking Ivermectin.
How Long Does Ivermectin Stay in Your System?
Duration of Effect
After oral administration, Ivermectin dosage reaches peak plasma concentrations in about 4 hours and has a half-life of around 18 hours. However, its antiparasitic effects can last much longer due to how it works against the life cycle of parasites.
- Peak Effect: 4–5 hours post-dose
- Duration: Up to several days, depending on the condition being treated
- Clearance: Metabolized in the liver and excreted in feces
Who Should Avoid Taking Ivermectin?
Ivermectin Precautions
Though Ivermectin is generally safe when used appropriately, it is not suitable for everyone. Some groups should avoid it altogether, while others should consult a healthcare provider before starting the medication.
Groups That Should Avoid Ivermectin
- 👶 Children under 15 kg or younger than 5 years
- 🤰 Pregnant women (especially during the first trimester)
- 🧓 Elderly individuals with liver or kidney issues
- 🧬 People with Loa loa infection (risk of serious brain damage)
- 💊 Patients on medications that interact with Ivermectin (e.g., warfarin, certain sedatives)
Ivermectin and Pregnancy: Is It Safe?
Ivermectin and Pregnancy
Ivermectin is classified as a Pregnancy Category C drug by the FDA. This means that while animal studies have shown some risk to the fetus, there are no well-controlled human studies.
- 📌 Recommendation: Avoid unless absolutely necessary and under strict medical supervision.
- 🤱 Breastfeeding: Small amounts may pass into breast milk. Safety in nursing infants has not been fully established.
Is Ivermectin Safe for People With Liver Disease?
Ivermectin Liver Safety
Ivermectin is metabolized in the liver, primarily through cytochrome P450 enzymes (CYP3A4). Patients with liver disease may experience slower metabolism, leading to drug accumulation and increased side effects.
- 🧑⚕️ Recommendation: Use caution or avoid. Dose adjustments may be necessary.
- 📈 Monitor liver enzymes if taking Ivermectin long-term or repeatedly.
Can Ivermectin Be Used Long-Term?
Chronic Use Risks
Ivermectin is not designed for continuous or long-term use. Repeated or high-dose usage has not been extensively studied and may lead to toxicity.
Potential risks of long-term use include:
- Neurotoxicity (e.g., confusion, tremors, seizures)
- Liver damage
- Drug resistance in parasites
Only use long-term under strict medical supervision and in the context of diseases requiring extended treatment, like strongyloidiasis in immunocompromised individuals.
