How we grade severity & evidence

Severity levels

  • Contraindicated: These should generally not be used together.
  • Major: Potentially serious — often needs a change or close monitoring.
  • Moderate: Can be significant — usually manageable with monitoring.
  • Minor: Usually limited clinical impact.

Evidence grades

  • Established: Well documented — supported by controlled studies or strong clinical data.
  • Probable: Good supporting evidence, though not definitively proven.
  • Suspected: Some evidence suggests this interaction, but it is not well established.
  • Possible: Limited or conflicting evidence; the interaction may occur.
  • Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.

Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.

Of 532 documented Sertraline interactions, 18 are rated moderate — including this one.

The Bottom Line
Taking sertraline with dihydroergotamine may add to serotonin activity and, in theory, cause weakness, overactive reflexes, or poor coordination. Keep taking both as prescribed, watch for these symptoms, and report them to your care team.

You've been prescribed sertraline (an antidepressant) along with dihydroergotamine, a medicine used to treat migraines. Both of these can affect serotonin, a chemical messenger in your body. When taken together, there is a possible risk of side effects like muscle weakness, overactive reflexes, and trouble with coordination.

Please know this is considered a theoretical risk, meaning it hasn't been strongly proven, and many people take these safely. Keep taking both as prescribed, but let your pharmacist or doctor know you're on both so they can keep an eye on you. If you notice new weakness, jerky reflexes, or feeling unsteady, reach out to them.

Interaction: Coadministration of dihydroergotamine (an ergot-derivative serotonergic agonist) with the SSRI sertraline may additively increase serotonergic activity, raising the risk of weakness, hyperreflexia, and incoordination (features overlapping serotonin toxicity).

  • Direction: Additive serotonergic effect; neither agent is a prodrug affecting this pathway.
  • Mechanism: Unknown/presumed pharmacodynamic.
  • Onset: Rapid.
  • Evidence: Theoretical; severity moderate.
  • Management: Monitor for neuromuscular and autonomic serotonergic signs. Dose/therapy may be individualized; consider alternatives if symptoms emerge.

What happens

An increased risk of weakness, hyperreflexia and incoordination

Interaction Deep Dive

Giving dihydroergotamine together with selective serotonin reuptake inhibitors may heighten the likelihood of incoordination, hyperreflexia and weakness123.

How to manage this interaction

This combination can be used with care, and your care team can manage it.

  • Keep taking both as prescribed unless your prescriber tells you otherwise.
  • Your team may monitor you more closely for symptoms, especially since effects can appear quickly.

Tell your pharmacist and doctor you take both so they can tailor the plan to you.

Management is individual — confirm any change with your pharmacist or prescriber.
