Results from observational studies provide good information.

Results from observational studies provide good information of the hit and tolerability of dutasteride in a large signaling of patients treated over a long full stop of up to 4 eld (Roehrborn et al. 2002c, 2004b; Andriole & Kirby 2003; Debruyne et al. 2007). In acquisition, up to 1 year's comparative data with dutasteride and finasteride have been obtained from two studies (ARI40001 1-year temporal property, and ARIA2001, a 24-week study) (Andriole & Kirby 2007; Mark Wayne Clark et al. 2007).
These studies show that the frequency of full general adverse events with dutasteride was similar to that with medication. The example was an elevated relative incidence of sexually-related adverse events which were seen more commonly with dutasteride in the outset 6 months of direction compared with placebo; quality 4.7 vs 1.7% (P<0.05), style="font-weight: bold;">finasteride (5 mg/day) were similar (Clark et al. 2004).
