IMPORTANT DRUG INTERACTIONS

Potentially hazardous interactions with other drugs

Analgesics: increased risk of bleeding with aspirin and NSAIDs; risk of CNS toxicity increased with tramadol

Anticoagulants: effect of coumarins possibly enhanced

Antidepressants: increased risk of toxic CNS effects of MAOIs and moclobemide; sertraline and MAOIs should not be prescribed within a 2 week period of each other; avoid concomitant use with St John’s wort; possibly enhanced serotonergic effects with duloxetine; can increase tricyclics antidepressant concentration; increased agitation and nausea with tryptophan

Anti-epileptics: antagonism (lowered convulsive threshold)

Antimalarials: avoid concomitant use with artemether/lumefantrine

Antipsychotics: concentration of clozapine and pimozide increased – avoid concomitant use with pimozide

Antivirals: concentration reduced by efavirenz and darunavir; possibly increased concentration with ritonavir

Ciclosporin: may increase serotonin syndrome

Dopaminergics: increased risk of hypertension and CNS excitation with selegiline – avoid concomitant use; increased risk of CNS toxicity with rasagiline – avoid concomitant use

Dopaminergics: hypertension and CNS excitation5HT 1 agonist: increased risk of CNS toxicity with sumatriptan – avoid concomitant use; possibly increased risk of serotonergic effects with frovatriptanLinezolid: use with caution

Lithium: increased risk of CNS effects; lithium toxicity reported

Sibutramine: increased risk of CNS toxicity – avoid concomitant use
