| Drug | Interaction | Comments |
|---|---|---|
| Alcohol | Does not potentiate cognitive and motor effects of alcohol | Concomitant use not recommended |
| Antiarrhythmic agents (e.g., encainide, flecainide, propafenone) | Potential for increased plasma antiarrhythmic concentrations; may result in increased risk of serious, potentially fatal, adverse cardiac effects (e.g., cardiac arrhythmias) | Adjust dosages as needed |
| Antidepressants, tricyclic (TCAs) (e.g., desipramine, imipramine) | Decreased TCA metabolism | Monitor plasma TCA concentrations and adjust dosage as needed |
| Atenolol | β-adrenergic blocking activity not affected by sertraline | |
| Benzodiazepines (e.g., diazepam) | Decreased diazepam clearance | |
| Carbamazepine | Pharmacokinetic interaction unlikely | |
| Cimetidine | Increased AUC, peak concentration, and elimination half-life of sertraline | |
| Cisapride | Increased cisapride metabolism | Clinical importance unlikely |
| Clozapine | Increased plasma clozapine concentrations | Monitor closely; consider reduction in clozapine dosage |
| Digoxin | No change in digoxin pharmacokinetics | |
| Disulfiram or other agents likely to produce disulfiram-like reactions (e.g., metronidazole) | Possible disulfiram reaction due to alcohol content in sertraline oral concentrate solution | Concomitant use with sertraline oral concentrate contraindicated |
| Fluoxetine | Potential for serotonin syndrome | Allow appropriate period of time to elapse between discontinuance of fluoxetine and initiation of sertraline and vice versa |
| 5-HT1 receptor agonists (“triptans”) | Potentially life-threatening serotonin syndrome | Observe carefully if used concomitantly, particularly during treatment initiation, dosage increases, or when another serotonergic agent is initiated |
| Isoniazid | Potential for serotonin syndrome | |
| Linezolid | Possible serotonin syndrome | Use with caution |
| Lithium |
Possible serotonin syndrome Pharmacokinetic interaction unlikely |
Use with caution Monitor serum lithium concentrations; adjust dosage accordingly |
| MAO inhibitors (e.g., moclobemide [not commercially available in the US], selegiline) | Potentially fatal serotonin syndrome or NMS |
Concomitant use contraindicated Allow at least 2 weeks to elapse between discontinuance of MAO inhibitor and initiation of sertraline and vice versa |
| NSAIAs (e.g., aspirin) | Increased risk of bleeding | Use with caution |
| Phenytoin |
No change in phenytoin pharmacokinetics or pharmacodynamics observed in one study However, potential increase in plasma phenytoin concentrations and subsequent toxicity reported with sertraline and other SSRIs Decreased plasma sertraline concentrations reported during concurrent phenytoin therapy |
Monitor plasma phenytoin concentrations and adjust phenytoin dosage as necessary, particularly in patients with multiple medical conditions and/or those receiving multiple medications concomitantly |
| Pimozide | Increased plasma pimozide concentrations; risk of QT prolongation | Concomitant use contraindicated |
| Propranolol | Pharmacokinetic interaction unlikely | |
| Sibutramine | Possible serotonin syndrome | Use with caution |
| SSRIs and SNRIs | Possible serotonin syndrome | Avoid concomitant use |
| Thioridazine | Increased plasma thioridazine concentrations; risk of serious, potentially fatal, adverse cardiac effects (e.g., cardiac arrhythmias) | Concomitant use not recommended |
| Tolbutamide | Decreased tolbutamide clearance | Clinical importance unknown |
| Tramadol | Possible serotonin syndrome | Use with caution |
| Tryptophan and other serotonin precursors | Possible serotonin syndrome | Concomitant use not recommended |
| Valproic acid | Possible interaction not systematically evaluated | Monitor plasma valproate concentrations and adjust valproic acid dosage accordingly |
| Warfarin | Possible increased PT and risk of bleeding |
Use with caution Monitor PT whenever sertraline is initiated or discontinued |
