OBJECTIVE: To determine whether titrating up and tapering down of desvenlafaxine (administered as desvenlafaxine succinate) improves its tolerability in postmenopausal women with vasomotor symptoms (VMS). METHODS: In the 1-week titration phase, participants received desvenlafaxine 100 mg/d (no titration), desvenlafaxine 50 mg/d, desvenlafaxine 25 mg/d (4 days) then 50 mg/d (3 days), or desvenlafaxine 25 mg/d. Participants then received open-label desvenlafaxine 100 mg/d for 15 weeks. In the 2-week taper phase, participants received placebo, desvenlafaxine 50 mg/d then placebo (7 days each), desvenlafaxine 50 mg/d then 25 mg/d (7 days each), or desvenlafaxine 50 mg/d every other day. Primary endpoints included nausea incidence during the first 2 weeks of treatment and Discontinuation-Emergent Signs and Symptoms (DESS) Checklist total scores after taper weeks 1 and 2. RESULTS: Nausea incidence was significantly lower for the desvenlafaxine 25 mg/d (19%) and 50 mg/d (22.6%) titration regimens vs. no titration (35.2%; p=0.004 and p=0.035, respectively). At taper week 1, mean DESS scores were significantly lower for desvenlafaxine 50 mg every other day (2.26, p<0.001), 50/25 mg/d (2.28, p<0.001), and 50 mg/d-placebo (1.84, p<0.001) taper regimens vs. no taper (7.07). At week 2, the mean DESS total score was significantly higher for the desvenlafaxine 50 mg/d-placebo regimen vs. no taper (4.46 vs. 2.44, respectively; p=0.009). Desvenlafaxine 50 mg every other day was the least tolerated of the taper regimens. CONCLUSIONS: Titration regimens may improve tolerability of desvenlafaxine 100 mg/d in postmenopausal women with VMS. Taper regimens of desvenlafaxine 50 mg/d-placebo or 50/25-mg/d, were better tolerated than abrupt discontinuation or desvenlafaxine 50 mg given every other day taper regimen.
