Drug & supplement interaction

Aloe + Sumatriptan

Sumatriptan brand name: Tosymra.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Aloe and Sumatriptan 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 two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Aloe and Sumatriptan

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 Sumatriptan and Aloe 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.

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.

How we checked

Why No Interaction Is Listed for Sumatriptan

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sumatriptan is filed under 4 classifications — including qt interval-prolonging drugs, serotonergic drugs, serotonergic drugs. Aloe has documented interactions with 7 drug classes — the most serious being digoxin (lanoxin) (major), anticoagulant/antiplatelet drugs (moderate) and antidiabetes drugs (moderate) — and none of Sumatriptan’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Aloe and Sumatriptan May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

    Aloe

    “Topically, aloe gel has occasionally been associated with burning, itching, eczema, erythema, contact dermatitis, popular eruption, and urticaria. Also, a case of generalized nummular and popular dermatitis attributed to hypersensitivity has been reported for a 47-year-old male who used aloe leaf gel, both topically and orally, for 4 years.”

    Sumatriptan

    Listed in the ADVERSE REACTIONS section of the FDA label for Sumatriptan. Read the label on DailyMed ›

Reported for Aloe but not commonly for Sumatriptan: muscle weakness, stomach pain, kidney problems and low potassium.

Effects for Sumatriptan come from the ADVERSE REACTIONS section of its FDA label; effects for Aloe come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Aloe in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

There are also anecdotal reports and evidence from animal research that anthraquinones or aloe whole leaf extracts might induce abortion and stimulate menstruation; avoid using.

Lactation Possibly Unsafe

When aloe preparations are used orally. Cathartic and mutagenic anthraquinones present in aloe latex and aloe whole leaf extracts might pass into milk; avoid using.

From our pharmacist’s overview on the Sumatriptan page

“The supplement risk that matters most with sumatriptan (Tosymra) is serotonin overload. This migraine drug works through serotonin receptors, and 20 of the 50 interacting ingredients on file, 5-HTP among them, can push serotonin activity higher still, raising the risk of serotonin syndrome (agitation, racing heart, fever).”

About Aloe

What is Aloe?

Aloe
  • Minor burns and skin irritation
  • Wound healing
  • Constipation
  • Skin hydration and moisturizing
  • Digestive complaints
  • Hair and scalp care

Aloe vera gel is widely used on the skin for minor burns and irritation, and some research suggests it may help. Aloe latex (the yellow part) is a strong laxative that can cause cramping and is not considered safe for regular use. Talk to your pharmacist or doctor before taking aloe by mouth, and avoid oral aloe during pregnancy.

Aloe vera · Asphodelaceae · Leaves (gel from the inner leaf and latex from just under the skin) · Topical gels and creams, juice, capsules, tablets, and as an ingredient in cosmetics and skin care products

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

Aloe: dosing

There is no single standard dose of aloe. The right amount depends on the product, the form, and how it is used.For skin products, follow the directions on the label and apply to clean skin.

About Sumatriptan

What Is Sumatriptan Used For?

Brand name: Tosymra

Sumatriptan is used to stop a migraine headache once it starts — with or without aura (the visual or sensory warning signs some people get before a migraine). It is available as tablets, nasal sprays, nasal capsules, and subcutaneous (under-the-skin) injections for this purpose.

Sumatriptan subcutaneous injections (brands: Imitrex injection, Sumatriptan Injection, Sumatriptan Succinate Injection) are also approved to treat acute cluster headaches in adults. Sumatriptan is not used to prevent migraines or cluster headaches — it only treats attacks once they begin.

Most-Reported Side Effects for Sumatriptan

From FAERS, the FDA’s public side-effect reporting system (46,096 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Headache 3,911 reports
Nausea 3,510 reports
Migraine 3,445 reports
Fatigue 2,617 reports

Taking Aloe and Sumatriptan Together: Common Questions

Is it safe to take Aloe with Sumatriptan?
We do not list a known interaction between Aloe and Sumatriptan. 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.
Do Aloe and Sumatriptan have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Aloe and Sumatriptan combination checked?
Interactions in our licensed database are recorded against drug classes. Sumatriptan is filed under 4 classifications, and Aloe has documented interactions with 7 drug classes — none of Sumatriptan's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Aloe interact with any other medications?
Yes. Aloe has 461 documented drug interactions in our database — Sumatriptan is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Sumatriptan interact with any supplements?
Yes. Sumatriptan has documented interactions with 50 supplements in our database — Aloe is not one of them. The Sumatriptan interaction page linked on this page lists every one, ranked by severity.
