Temazepam 20 mg (Centrafarm) is a benzodiazepine indicated for the short-term management of insomnia, particularly when difficulty falling asleep or frequent nocturnal awakenings are present. It acts by enhancing the effect of GABA in the central nervous system, producing sedation and promoting uninterrupted sleep. Treatment should be limited to a few weeks, with gradual dose reduction to minimise withdrawal symptoms.
