Drug & supplement interaction

Tyrosine + 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 Tyrosine 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.

Tyrosine 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 Tyrosine 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.

Tyrosine safety at a glance

Tyrosine overall Use caution Generally well tolerated in healthy adults, but talk to a healthcare provider before regular use.
Pregnancy Use caution Not enough safety data; avoid supplemental doses unless a doctor advises otherwise.
Breastfeeding Use caution Not enough safety data, so caution is advised while breastfeeding.

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

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. Tyrosine has documented interactions with 2 drug classes — the most serious being levodopa (moderate) and thyroid hormone (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.

No Interaction Found — But Data Suggests Tyrosine 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.

  • Headache Additional detail

    Tyrosine

    “Orally, larger doses of tyrosine (150 mg/kg) can cause headache and fatigue. Taking a combination of tyrosine 4 grams, 5-hydroxytryptophan 800 mg, and carbidopa 100 mg can cause drowsiness and agitation. These effects can be mitigated by lowering the dosage.”

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 Tyrosine

What is Tyrosine?

  • Mental focus and alertness
  • Coping with stress
  • Fatigue and sleep loss
  • Mood support
  • Athletic and cognitive performance

L-tyrosine is an amino acid your body uses to make brain chemicals like dopamine and norepinephrine. Some studies suggest it may help mental performance during short-term stress, sleep loss, or cold, but the evidence is mixed and it is not proven for everyday focus or mood. It is generally well tolerated in healthy adults, but check with your pharmacist or doctor before using it, especially during pregnancy or if you have a thyroid condition.

Amino acid (made in the body or produced by fermentation/synthesis for supplements) · Capsules, tablets, powder, and as L-tyrosine or N-acetyl-L-tyrosine

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

Tyrosine: dosing

There is no official standardized dose for tyrosine, and the amounts used in studies vary widely. Because of this, the best approach is to follow the directions on the product label and not exceed them.Doses are often based on body weight in research settings and taken a short time before a stressful or demanding task.

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
Dizziness 2,121 reports

Taking Tyrosine and Sumatriptan Together: Common Questions

Is it safe to take Tyrosine with Sumatriptan?
We do not list a known interaction between Tyrosine 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 Tyrosine 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 Tyrosine and Sumatriptan combination checked?
Interactions in our licensed database are recorded against drug classes. Sumatriptan is filed under 4 classifications, and Tyrosine has documented interactions with 2 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 Tyrosine interact with any other medications?
Yes. Tyrosine has 21 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 — Tyrosine is not one of them. The Sumatriptan interaction page linked on this page lists every one, ranked by severity.
