Alpha Hydroxy Acids (ahas) and Tafenoquine

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 Tafenoquine and Alpha Hydroxy Acids (ahas) 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 Hydroxy Acids (ahas) at all — not against Tafenoquine, 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 Tafenoquine’s Own FDA Label Lists

This is not an interaction — none of it involves Alpha Hydroxy Acids (ahas).

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.

  • Low mood Worth acting on mentioned in 28.6% of FDA reports for Tafenoquine
  • Loss of vision Worth acting on
  • Memory problems Worth acting on
  • Unsteadiness Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Tafenoquine. Read the label on DailyMed › Where a percentage is shown, it is the share of 70 voluntary FDA FAERS reports for Tafenoquine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Alpha Hydroxy Acids (ahas)’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Alpha Hydroxy Acids (ahas) side to compare — that is a limit of the record, not a statement that Alpha Hydroxy Acids (ahas) has no side effects.

How to take them

Some Tafenoquine Products Have a Food Rule — Alpha Hydroxy Acids (ahas) Should Not Break It

At least one FDA label for a product containing Tafenoquine says to take it with food. If you take Alpha Hydroxy Acids (ahas) on an empty stomach out of habit, keep them separate — and take Tafenoquine with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Tafenoquine 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.

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.

From our pharmacist’s overview on the Tafenoquine page

“Tafenoquine (Krintafel, Arakoda) protects against malaria, including the relapsing kind that hides in the liver, and every supplement known to interact with it threatens the same thing, how much of the pill actually reaches your blood. That deserves genuine care, since a partly absorbed antimalarial can let parasites survive and resurf…”

About Alpha Hydroxy Acids (ahas)

What is Alpha Hydroxy Acids (ahas)?

  • Skin exfoliation
  • Anti-aging / wrinkles
  • Acne
  • Dry or rough skin
  • Uneven skin tone and dark spots

Alpha hydroxy acids (AHAs) are a group of acids, such as glycolic, lactic, and malic acid, most often used on the skin to exfoliate, smooth texture, and reduce signs of aging. They are best studied as topical skincare ingredients and can cause irritation and sun sensitivity. Talk with a pharmacist or dermatologist before starting, especially if you have sensitive skin or are pregnant.

Naturally derived from fruits, milk, and sugarcane, or made synthetically · Topical creams, lotions, serums, chemical peels, cleansers; some products are taken orally

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

Alpha Hydroxy Acids (ahas): dosing

There is no single standard dose for AHAs. The right amount depends on the specific acid, the product strength (concentration), and the formula's pH. Over-the-counter skincare products usually contain lower concentrations, while professional peels use much higher ones.The best approach is to follow the directions on your product label and start slowly, using it less often at first to see how your skin reacts. A pharmacist or dermatologist can help you choose an appropriate strength and routine.For oral AHA products, a reliable proven dose has not been established, so check with a healthcare professional before use.

About Tafenoquine

What Is Tafenoquine Used For?

Brand names: Krintafel, Arakoda

Tafenoquine is used for two distinct purposes depending on the product. Arakoda and Kodatef are used for malaria prophylaxis — that is, preventing malaria in adults 18 and older who are traveling to or living in areas where malaria is present.

Krintafel is used for the radical cure of Plasmodium vivax malaria — meaning it prevents the malaria parasite from coming back (relapsing) in patients 16 and older who are already being treated with chloroquine for an active P. vivax infection. Krintafel is not used to treat an active malaria attack on its own, and it should only be used alongside chloroquine, not other antimalarials.

Most-Reported Side Effects for Tafenoquine

From FAERS, the FDA’s public side-effect reporting system (70 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Depression 20 reports
Anxiety 18 reports
Post-traumatic stress disorder 15 reports
Anger 14 reports
Nausea 14 reports
