Mirtazapine serotonin activity is so low even at maximum doses that it is, in the words of one of the two doctors who know most about SS, about as likely to trigger it as a vitamin C tablet is (PDF). Plus, mirtazapine is a serotonin 5-HT2a receptor antagonist (blocker) which can prevent the body temperature spike which does the damage in SS although in humans the recommended treatments are the more potent 5-HT2a antagonists cyproheptadine and chlorpromazine.
Not sure about 10mg of citalopram, though that's not a therapeutic dose either
While it is more likely to have an effect than mirtazapine, even so you're unlikely to notice anything untoward.
