How are antidepressant medications selected?
The type of drug prescribed will depend on your symptoms, the presence of other medical conditions, other medicines you are currently taking, the cost of the prescribed treatments, and potential side effects. If you have had depression before, your provider may prescribe the same medicine that worked for you in the past. If you have a family history of depression, medicines that have been effective in treating your family member(s) may also be considered.
Usually you will start taking the medicine at a low dose. The dose will be gradually increased until it has reached the therapeutic dose, or until you start to see an improvement (unless side effects emerge).
