What preparation and dosage? How long should treatment be continued? How should treatment be stopped? What are the outcomes after treatment is stopped? Stopping HRT Options for tapering Slowly decrease daily dose Slowly decrease days/week of HT Back up to previous dose if hot flashes recur; then taper more slowly Continue progestins at least every 3 months Evidence to date suggests tapering t clearly better than stopping abruptly Grady D.
