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.
If you take dextroamphetamine (like Dexedrine) together with sertraline, there are two things to keep an eye on. First, sertraline can slow down how your body breaks down the amphetamine, so a bit more of it can build up in your system, which may make its effects stronger. Second, both drugs raise serotonin, a brain chemical, so combining them slightly raises the chance of a reaction called serotonin syndrome (things like fast heartbeat, sweating, shakiness, agitation, or fever).
This is mostly a theoretical concern, and many people take both safely. The good news is your care team can manage this by starting low and watching how you do. Just let them know you take both.
Effect: Sertraline may increase dextroamphetamine exposure and add to serotonergic burden.
- Mechanism: Sertraline inhibits CYP2D6, which partially metabolizes amphetamine, potentially raising amphetamine exposure; plus additive serotonergic (PD) effects increasing serotonin syndrome risk.
- Direction: Increased amphetamine effect (neither drug is a prodrug requiring activation).
- Evidence: Theoretical; magnitude and onset unspecified.
- Management: If coadministration is required, initiate at lower doses and monitor closely during initiation and titration for serotonin syndrome (hyperthermia, autonomic instability, clonus, agitation). Discontinue both if serotonin syndrome is suspected.
What happens
Increased amphetamine exposure and an increased risk of serotonin syndrome
Interaction Deep Dive
When an amphetamine is given together with a serotonergic drug that inhibits CYP2D6, amphetamine exposure may rise and the likelihood of serotonin syndrome may increase. Should clinical circumstances require using both an amphetamine and such an agent at the same time, begin therapy at reduced doses and observe patients closely, particularly when starting treatment and when adjusting the dose. Both medications should be stopped if serotonin syndrome is suspected1.
Why it happens (mechanism)
Inhibition of CYP2D6-mediated metabolism of amphetamine; additive serotonergic effects
How to manage this interaction
Both medicines can usually be used together when your prescriber decides it's worthwhile, with a few sensible precautions.
- Keep taking both as prescribed unless your doctor or pharmacist tells you otherwise.
- Your care team may start at a lower dose and adjust it individually, especially when first combining them or changing a dose.
- Expect closer monitoring early on.
- Get medical help right away for signs of serotonin syndrome: agitation, fast heartbeat, high fever, heavy sweating, muscle twitching, shivering, or confusion.
- Ask your pharmacist before adding any new serotonergic medicines or supplements.
Management is individual — confirm any change with your pharmacist or prescriber.
Common questions
Can I take Dextroamphetamine and Sertraline together?
Sertraline can raise dextroamphetamine levels and add to serotonin effects, so watch for serotonin syndrome symptoms; your care team can manage this by starting low and monitoring you. Do not change either medicine on your own. Always confirm with your pharmacist or prescriber before making any change.
How serious is the Dextroamphetamine and Sertraline interaction?
It is rated major. Potentially serious — often needs a change or close monitoring.
How quickly could this interaction happen?
The documented onset is "unspecified". The timing of this interaction is not well characterized.
