Healthcare providers are told to closely watch all patients taking antidepressants for worsening symptoms and for new suicidal thoughts or behaviors. The Medication Guide says this risk is most important in the first few months of treatment or when the dose is changed.

🛑 Who should not take Sertraline, and who should be careful
The label says not to take it if
- You take a monoamine oxidase inhibitor (MAOI), or you have taken one within 2 weeks of stopping sertraline, unless your healthcare provider directs otherwise. The label includes linezolid and intravenous methylene blue in this group.
- You have stopped taking an MAOI in the last 2 weeks, unless your healthcare provider directs otherwise.
- You take pimozide.
- You have a known allergy (hypersensitivity) to sertraline or its inactive ingredients.
- You take any other medicine that contains sertraline.
Tell your doctor before taking it if
- Tell your provider if you take a monoamine oxidase inhibitor (MAOI), including the antibiotic linezolid.
- Tell your provider about any history of seizure disorders. The label says to use this medicine with caution in people with seizure disorders.
- The label says prescribers should screen patients for bipolar disorder, because sertraline can trigger manic or hypomanic episodes.
- Tell your provider if you have narrow angles in the eye that have not been treated, since the label says antidepressants should be avoided in that case.
- Tell your provider about risk factors for changes in heart rhythm (QTc prolongation), since the label says to use sertraline with caution in those patients.
- Tell your provider if you take blood thinners, aspirin, NSAIDs, or other antiplatelet drugs, because of the bleeding risk.
- Tell your provider if you are pregnant, planning a pregnancy, or taking antidepressants in late pregnancy. The label discusses pregnancy risks in detail.
- The Medication Guide says to keep all follow-up visits and to call between visits if you are worried about symptoms.
🔀 Sertraline with other medicines, food and alcohol
The label says to discuss these with your doctor or pharmacist
- MAOIs (such as selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, methylene blue): The label says these increase the risk of serotonin syndrome and are not to be used with sertraline.
- Pimozide: The label says sertraline and pimozide must not be used together because of possible heart rhythm problems.
- Other serotonergic drugs (such as other SSRIs, SNRIs, triptans, tricyclic antidepressants, opioids, lithium, tryptophan, buspirone, amphetamines, and St. John's Wort): The label says these can increase the risk of serotonin syndrome.
- Blood thinners and bleeding-risk drugs (such as aspirin, clopidogrel, heparin, and warfarin): The label says these can increase bleeding risk. For warfarin, the label says the INR should be monitored carefully.
- NSAIDs such as ibuprofen or naproxen: The Medication Guide says these can increase bleeding or bruising risk when taken with sertraline.
- Drugs processed by the CYP2D6 pathway: The label says the dose of these drugs may need to be reduced.
- Other protein-bound drugs: The label says the dose of these may need to be adjusted.

🤰 Sertraline in pregnancy and breastfeeding
Pregnancy
The label includes a pregnancy exposure registry, the National Pregnancy Registry for Antidepressants, at 1-866-961-2388. The label says that SSRIs, particularly in the month before delivery, have been linked to a less than 2-fold increase in the risk of postpartum hemorrhage. It says published studies of sertraline in the first trimester suggest no difference in major birth defect risk compared with the background rate, while some studies report increases for specific birth defects and those results are inconclusive. The label also mentions clinical considerations for newborns exposed during the third trimester. Talk with your healthcare provider about these risks and the risks of not treating depression.
Breastfeeding
The label does not say.
