Should Ivermectin Be Taken With Food? Yes, according to scabies experts, ivermectin should be taken with a meal to increase its bioavailability, despite general guidelines suggesting an empty stomach. FOODS.EDU.VN is here to clarify the optimal way to take ivermectin for scabies treatment, ensuring you receive the most effective care. Dive into the details about ivermectin absorption, dosage recommendations, and alternative scabies treatments.
1. What is Ivermectin and Why Is It Used?
Ivermectin is a medication used to treat parasitic infections. It is effective against various worms, lice, and mites. While not FDA-approved for scabies, it is often prescribed off-label due to its effectiveness, with both topical permethrin and oral ivermectin showing similar efficacy in treating scabies.
1.1 Understanding Ivermectin’s Role in Treating Scabies
Scabies is a skin condition caused by tiny mites that burrow into the skin, leading to intense itching. Ivermectin works by paralyzing and killing these mites.
1.1.1 How Ivermectin Works Against Scabies Mites
Ivermectin interferes with the nerve and muscle function of the mites, causing paralysis and death. This action helps to eliminate the infestation and relieve symptoms.
1.2 Why Ivermectin is Prescribed Off-Label for Scabies
Doctors sometimes prescribe ivermectin “off-label” for scabies when other treatments are ineffective or unsuitable. “Off-label” use means the drug is used in a way that is not approved by the FDA, but doctors can prescribe it if they believe it is the best course of treatment for their patient.
1.2.1 Scabies Treatment Challenges and Ivermectin’s Potential
Scabies can be difficult to treat, especially in cases of crusted scabies or when patients have compromised immune systems. Ivermectin offers a convenient oral option, often used in combination with topical treatments for better results.
2. The Timing Question: Should Ivermectin Be Taken With Food?
General guidelines often recommend taking ivermectin on an empty stomach. However, scabies experts suggest taking ivermectin with a meal to increase its bioavailability.
2.1 General Ivermectin Guidelines vs. Expert Recommendations
While standard medical advice often suggests taking ivermectin on an empty stomach for other conditions, treating scabies is different. Experts in scabies treatment recommend taking it with food.
2.1.1 Why Standard Guidelines Suggest an Empty Stomach
Taking ivermectin on an empty stomach is generally advised to reduce the risk of drug interactions and maximize absorption.
2.2 The Rationale Behind Taking Ivermectin With Food for Scabies
Scabies experts recommend taking ivermectin with food because it increases the drug’s absorption, making it more effective in killing scabies mites.
2.2.1 Enhancing Bioavailability: How Food Affects Ivermectin Absorption
When ivermectin is taken with food, especially fatty foods, the drug’s bioavailability increases. This means more of the drug is absorbed into the bloodstream, leading to a higher concentration in the body and a more effective treatment.
Optimizing ivermectin absorption: Enhanced bioavailability with a meal promotes effective scabies treatment, according to FOODS.EDU.VN experts.
3. Understanding Bioavailability and Absorption
Bioavailability refers to the extent and rate at which the active drug enters systemic circulation, thereby having access to the site of action.
3.1 What is Bioavailability?
Bioavailability is a measure of how much of a drug reaches the bloodstream and is available to have an effect.
3.1.1 The Importance of Bioavailability in Medication Effectiveness
High bioavailability means more of the drug is available to fight the infection or condition, leading to better outcomes.
3.2 Factors Affecting Ivermectin Absorption
Several factors can affect how well ivermectin is absorbed, including the presence of food in the stomach, the type of food consumed, and individual metabolic differences.
3.2.1 The Role of Food in Drug Absorption
Food can either enhance or inhibit drug absorption, depending on the drug’s properties. For ivermectin, food, especially fatty foods, enhances absorption.
4. Dosage Recommendations for Ivermectin in Scabies Treatment
The typical dosage of ivermectin for scabies is 200µg/kg per dose, taken with food. Two doses are usually administered, with each dose taken 7 to 14 days apart.
4.1 Standard Dosage for Classic Scabies
For classic scabies, the standard recommendation is two doses of oral ivermectin, each 7 to 14 days apart.
4.1.1 Calculating the Correct Dosage Based on Weight
To calculate the correct dosage, multiply the patient’s weight in kilograms by 200µg. For example, a person weighing 50 kg would need 10,000µg, or 10mg, of ivermectin per dose.
4.2 Dosage Adjustments for Crusted Scabies
Crusted scabies, a more severe form of the infestation, requires more aggressive treatment.
4.2.1 Higher Doses and Combination Therapies for Severe Cases
In cases of crusted scabies, ivermectin is often administered in combination with topical treatments like permethrin cream. The frequency of ivermectin doses may also be increased, with some experts recommending three to seven doses depending on the severity of the infection.

5. What to Eat When Taking Ivermectin
To maximize the absorption of ivermectin, it is best to take it with a meal that contains a good amount of fat.
5.1 Ideal Foods to Enhance Ivermectin Absorption
Fatty foods can help increase the bioavailability of ivermectin.
5.1.1 High-Fat Meal Suggestions for Optimal Absorption
Examples of good food choices include:
- Avocado
- Nuts and seeds
- Cheese
- Fatty fish (like salmon or tuna)
- Olive oil
5.2 Foods to Avoid When Taking Ivermectin
There are no specific foods that need to be avoided when taking ivermectin. However, ensure the meal contains enough fat to enhance absorption.
5.2.1 Any Food Interactions to Be Aware Of?
