Lamotrigine 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 Lamotrigine (Lamotrigine) should be prescribed and used after age 60. The standard 25mg, 50mg, 100mg, 200mg starting strengths are usually adjusted, and the safety priorities shift.
Dose adjustments after 60
According to the prescribing information, most adults over 65 start Lamotrigine at the lowest available strength of 25mg, 50mg, 100mg, 200mg and titrate up only with clear benefit and good tolerance. Reduced renal and hepatic function in older age slows clearance of Lamotrigine 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 Lamotrigine after 60. Lamotrigine is a phenyltriazine that selectively blocks voltage-gated sodium channels, stabilising neuronal membranes and reducing the release of excitatory neurotransmitters, particularly glutamate. A standing blood pressure check after the first weeks of therapy is a simple, useful precaution.

According to the prescribing information for Lamotrigine, the full medication list should be reviewed with the prescriber before starting and at any change.
