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.
Let's talk about taking dipyrone (a pain and fever medicine) together with sertraline (an antidepressant). Two things can happen. First, both can make it easier to bleed, so together they may raise your risk of bleeding, including in the stomach or intestines. Second, dipyrone may cause your body to clear sertraline faster, which can make the sertraline work less well for your mood.
Please don't stop or change either medicine on your own. Your care team can manage this well by watching you a bit more closely, checking how you're feeling, and adjusting doses if needed. Tell your pharmacist or doctor about any stomach pain, black stools, or unusual bruising.
Effect: Concurrent dipyrone (metamizole) and sertraline may increase bleeding risk (GI and intracranial) and reduce sertraline exposure.
- Mechanism: SSRI-mediated depletion of platelet serotonin impairs hemostasis; dipyrone may induce CYP2B6 and/or CYP3A4, lowering sertraline AUC.
- Direction: Additive bleeding risk plus reduced antidepressant efficacy. Neither is a relevant prodrug here.
- Evidence/onset: Probable; onset unspecified.
- Management: Monitor for GI bleeding (higher risk in elderly and prior ulcer disease). Consider acetaminophen, an antidepressant with less serotonin reuptake inhibition, or antiulcer prophylaxis. If coadministered, use TDM to dose-adjust sertraline and repeat if dipyrone dose changes or stops.
What happens
An increased risk of bleeding and a reduced sertraline exposure
Interaction Deep Dive
Giving metamizole (dipyrone) together with sertraline can markedly lower sertraline levels3 and raise the likelihood of both intracranial 1 and gastrointestinal bleeding. Whenever an SSRI is combined with an NSAID, watch carefully for indications of adverse events such as GI bleeds, particularly in older patients and in those who have previously had GI ulcers. Alternative approaches include selecting a different analgesic (for example, acetaminophen), choosing antidepressants that inhibit serotonin reuptake to a lesser degree, or adding antiulcer prophylaxis 2. Should sertraline and metamizole be used at the same time, apply therapeutic drug monitoring (TDM) to adjust the sertraline dose, and perform TDM again if the metamizole dose is altered or its therapy is stopped 3.
Why it happens (mechanism)
Depletion of platelet serotonin by SSRI; possible induction of CYP2B6 and/or CYP3A4 metabolism of sertraline
How to manage this interaction
If you take both, keep taking them as prescribed and let your care team guide any changes.
- Closer monitoring: Your team may watch you for stomach bleeding, especially if you are older or have had ulcers.
- Alternatives: They may consider a different pain option (such as acetaminophen), a different antidepressant, or a stomach-protecting medicine.
- Blood-level checks: If both are used together, your team may use blood level testing to fine-tune your sertraline dose, and recheck if your dipyrone dose changes or stops.
Report black or bloody stools, vomiting that looks like coffee grounds, easy bruising, or a return of low mood to your pharmacist or doctor.
Management is individual — confirm any change with your pharmacist or prescriber.
Literature reports

a) In a retrospective analysis, median sertraline plasma concentrations were significantly lower when metamizole and sertraline were used together (n=15) than in matched sertraline controls (n=19; 14 vs 42 ng/mL); no significant difference was found between the metamizole and ibuprofen groups (n=19; 14 vs 31 ng/mL), or between the ibuprofen and sertraline control groups (31 vs 42 ng/mL). Because ibuprofen was not anticipated to have a pharmacokinetic interaction with sertraline, it functioned as an additional control group. In addition, significantly more patients in the metamizole and sertraline group had sertraline levels below the therapeutic reference range of 10 to 150 ng/mL than in either the concomitant ibuprofen group (40% vs 5.3%) or the sertraline control group (40% vs 0%). Patients received a median sertraline dose of 100 mg/day in both the metamizole and ibuprofen groups, and 125 mg/day in the sertraline control group; the analgesics (metamizole or ibuprofen) were taken daily 3.
Common questions
Can I take Sertraline and Dipyrone together?
Using dipyrone with sertraline can raise bleeding risk and may weaken sertraline's effect; keep taking both as prescribed and ask your care team about monitoring, stomach protection, or safer alternatives. Always confirm with your pharmacist or prescriber before making any change.
How serious is the Sertraline and Dipyrone 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.
