Alpha-linolenic Acid (ala) + Ivermectin
Ivermectin brand names: Stromectol, Mectizan, Sklice, Soolantra.
We found no known interaction between Alpha-linolenic Acid (ala) and Ivermectin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Ivermectin states a food rule worth keeping to.
Alpha-linolenic Acid (ala) and Ivermectin
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Ivermectin and Alpha-linolenic Acid (ala) in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Alpha-linolenic Acid (ala) at all — not against Ivermectin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Some Ivermectin Products Have a Food Rule — Alpha-linolenic Acid (ala) Should Not Break It
At least one FDA label for a product containing Ivermectin says to take it on an empty stomach. Most supplements — Alpha-linolenic Acid (ala) included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Ivermectin on its own and move Alpha-linolenic Acid (ala) to a meal later in the day.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ivermectin products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
Patients should take tablets on an empty stomach with water.
From the Dosage and Administration section of the FDA label we read for Ivermectin — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›
A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Alpha-linolenic Acid (ala)
What is Alpha-linolenic Acid (ala)?
- Heart health
- Source of omega-3 fats
- General wellness
- Inflammation
- Plant-based omega-3 alternative to fish oil
Alpha-linolenic acid (ALA) is an essential plant-based omega-3 fatty acid your body cannot make, so you must get it from food. It is found in flaxseed, walnuts, and certain vegetable oils, and most people benefit from including these foods as part of a balanced diet. ALA is generally safe from food, but talk to a pharmacist or doctor before taking high-dose supplements.

An interaction check asks whether these two react with each other — it does not ask whether Alpha-linolenic Acid (ala) is a good idea for someone in your situation. Here is what our Alpha-linolenic Acid (ala) record says about it on its own.

About Ivermectin
What Is Ivermectin Used For?
Brand names: Stromectol, Mectizan, Sklice, Soolantra
Ivermectin tablets (including Stromectol) are used to treat two parasitic infections: strongyloidiasis (a roundworm infection of the intestinal tract) and onchocerciasis (river blindness, caused by a parasitic worm spread by blackfly bites). These are prescription uses for serious infections.
Topical ivermectin lotion — sold under several names including RID One and Done, Head Lice Treatment Ivermectin Lotion, Scalp Care Lotions, and others — is applied to the scalp to treat head lice. A separate topical ivermectin cream (1%), available as Soolantra and ivermectin cream 1%, is used to treat the inflammatory pimple-like bumps of rosacea.
Most-Reported Side Effects for Ivermectin
From FAERS, the FDA’s public side-effect reporting system (6,298 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
