Rate and appropriateness of polypharmacy in older patients with hemophilia compared with age-matched controls.

The rate of polypharmacy and the appropriateness of medications other than those for haemophilia and related comorbidities are acceptable in Italian PWHs, and better than those in their age peers without haemophilia, perhaps owing to drug tailoring and deprescribing by the specialized haemophilia centres at the time of regular visits. However, the PWHs investigated herewith were relatively young and the rate of polypharmacy and related PDDIs may become more prominent and crucial when older ages are reached, suggesting the need of continuous surveillance on prescribed drugs and the risk of drug-drug interactions.
