Drug & supplement interaction

Alpha-linolenic Acid (ala) + Ivermectin

Ivermectin brand names: Stromectol, Mectizan, Sklice, Soolantra.

No Known Interaction
The bottom line No known interaction

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.

What Ivermectin’s Own FDA Label Lists

This is not an interaction — none of it involves Alpha-linolenic Acid (ala). These are the most notable effects listed in the ADVERSE REACTIONS section of Ivermectin’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Loss of vision Worth acting on
  • Wheezing Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on
  • Chest pain Worth acting on
  • Anemia Worth acting on
  • Hives Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on

Showing the 10 most notable of 30 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Ivermectin. Read the label on DailyMed › Where a percentage is shown, it is the share of 6,298 voluntary FDA FAERS reports for Ivermectin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Alpha-linolenic Acid (ala)’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Alpha-linolenic Acid (ala) side to compare — that is a limit of the record, not a statement that Alpha-linolenic Acid (ala) has no side effects.

How to take them

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.

Seeds, nuts, and vegetable oils (dietary source) · Flaxseed oil, capsules, softgels, flaxseed, walnuts, canola and soybean oils

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

Taking Alpha-linolenic Acid (ala) and Ivermectin Together: Common Questions

Is it safe to take Alpha-linolenic Acid (ala) with Ivermectin?
We do not list a known interaction between Alpha-linolenic Acid (ala) and Ivermectin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Should I take Alpha-linolenic Acid (ala) and Ivermectin at the same time of day?
At least one FDA label for a product containing Ivermectin says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Ivermectin on its own and move Alpha-linolenic Acid (ala) to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Ivermectin interact with any supplements?
Yes. Ivermectin has documented interactions with 58 supplements in our database — Alpha-linolenic Acid (ala) is not one of them. The Ivermectin interaction page linked on this page lists every one, ranked by severity.
