Mirtazapine after 60: doses and safety in older adults
Older adults metabolise medications differently, accumulate more comorbidities and take more concomitant drugs than younger users — all of which affect how Mirtazapine (Mirtazapine) should be prescribed and used after age 60. The standard 7.5mg, 15mg, 30mg, 45mg starting strengths are usually adjusted, and the safety priorities shift.
Dose adjustments after 60
According to the prescribing information, most adults over 65 start Mirtazapine at the lowest available strength of 7.5mg, 15mg, 30mg, 45mg and titrate up only with clear benefit and good tolerance. Reduced renal and hepatic function in older age slows clearance of Mirtazapine and prolongs effects. Caution is greater in the very old (>75).
Specific risks to consider
Falls, postural hypotension, confusion and interaction with cardiovascular medications are the main amplified risks for Mirtazapine after 60. Mirtazapine antagonises presynaptic α2-adrenergic autoreceptors and heteroreceptors, increasing noradrenaline and serotonin release. A standing blood pressure check after the first weeks of therapy is a simple, useful precaution.
