Crystal Therapy 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 Crystal Therapy in our sources. This does not guarantee that the combination is completely free of risk — research on Crystal Therapy alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Crystal Therapy 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.

Crystal Therapy is a treatment rather than something you take. Tell whoever provides it which medicines you use, and ask your prescriber whether it is appropriate for your health and treatment. 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.

Crystal Therapy safety at a glance

Crystal Therapy overall Use caution Physically low-risk, but it has no proven medical effect and should never replace medical treatment.
Pregnancy Use caution Using stones externally is unlikely to cause harm, but it should not replace prenatal care; avoid ingesting crystal-infused water.
Breastfeeding Use caution External crystal use is unlikely to affect nursing, but it offers no proven benefit and should not replace medical care.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

What Tafenoquine’s Own FDA Label Lists

This is not an interaction — none of it involves Crystal Therapy. These are the most notable effects listed in the ADVERSE REACTIONS section of Tafenoquine’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 have Crystal Therapy and take the medicine. 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
  • Yellowing of the skin or eyes Worth acting on
  • Fainting Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • Hives Worth acting on

Showing the 10 most notable of 24 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 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. Crystal Therapy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Crystal Therapy side to compare — that is a limit of the record, not a statement that Crystal Therapy has no side effects.

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…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Crystal Therapy is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Crystal Therapy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Crystal Therapy and Tafenoquine records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Crystal Therapy

What is Crystal Therapy?

  • Stress and relaxation
  • Emotional balance
  • Meditation support
  • Energy and 'chakra' balancing
  • General sense of well-being

Crystal therapy is an alternative practice that uses gemstones placed on or around the body in the belief they affect energy and healing. There is no reliable scientific evidence that crystals have any direct healing effect on the body, and any benefits people feel are most likely due to relaxation or the placebo effect. It is not a substitute for medical care, but it is generally physically harmless when not used to replace proven treatment.

Crystals and gemstones (for example quartz, amethyst, rose quartz) · Polished stones, raw crystals, jewelry, wands, crystal-infused water

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

Crystal Therapy: dosing

There is no established or medically meaningful dose for crystal therapy, because it is a belief-based practice rather than a medicine. There is no amount of crystal use that has been shown to treat any condition.If you enjoy using crystals as part of a relaxation or meditation routine, treat it as a calming ritual rather than a treatment.

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
