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.
Taking amphetamine (like Dexedrine or Zenzedi) with sertraline needs a little extra care. There are two things going on. First, sertraline can slow down one of the liver pathways (called CYP2D6) that helps clear amphetamine from your body, so more of it may build up and its effects can feel stronger. Second, both medicines raise a brain chemical called serotonin, and together they can, rarely, push it too high. This is called serotonin syndrome.
Watch for things like a racing heart, high fever, shaking, muscle stiffness, sweating, agitation, or confusion. If those happen, get medical help right away. The good news: your care team can manage this by starting low, going slow, and keeping an eye on you.
Mechanism (two-pronged): Sertraline inhibits CYP2D6, which partially metabolizes amphetamine, potentially increasing amphetamine exposure. Both agents are serotonergic, producing additive serotonergic effects. Neither drug is a prodrug here, so inhibition increases active amphetamine levels.
- Direction: Increased amphetamine exposure and additive serotonin activity; elevated serotonin syndrome risk.
- Evidence: Theoretical.
- Onset: Unspecified; highest concern at initiation and dose titration.
- Management: If coadministration is required, initiate at lower doses, titrate cautiously, and monitor for serotonin syndrome (hyperthermia, autonomic instability, clonus, hyperreflexia, agitation). Discontinue both agents 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 blocks CYP2D6, the outcome can be greater amphetamine exposure along with a heightened chance of serotonin syndrome. Should the combined use of an amphetamine and this type of agent be necessary from a clinical standpoint, 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
Keep taking both medicines as prescribed unless your prescriber tells you otherwise. This combination can be used safely with the right precautions.
- Your care team may start the amphetamine at a lower dose and adjust it slowly. Doses may need to be individualized by your team.
- Expect closer monitoring, especially when starting or changing a dose.
- Learn the warning signs of serotonin syndrome: fast heartbeat, fever, sweating, shivering, muscle twitching or stiffness, agitation, or confusion.
- Seek medical help right away if those symptoms appear, and tell your pharmacist or prescriber about any new or worsening effects.
Management is individual — confirm any change with your pharmacist or prescriber.
Common questions
Can I take Amphetamine and Sertraline together?
Sertraline can raise amphetamine levels and both raise serotonin, so together they carry a real but manageable risk of serotonin syndrome. Your care team can start low, go slow, and monitor you closely, and you should get urgent help if you notice fever, fast heartbeat, muscle stiffness, or confusion. Always confirm with your pharmacist or prescriber before making any change.
