As fluoxetine takes a little while to build up in your system, some specialists suggest starting it while you lower the dose of the other drug, taking both drugs together for a week or two.
Change to 20mg fluoxetine liquid from:
When coming off antidepressants, an alternative to fluoxetine is to switch to clomipramine 100mg/day.
