OK the changing of meds will be a nightmare for her! As a general rule it takes around 6 weeks for any anti depressant medication to get fully into someone's system, and then each time the dose/meds are changed it takes the same amount of time. Meds also take about the same to get out of your system - so if she's on a med for 2 weeks and changes then she's going to have the starting side effects of 2 meds and one leaving her system too itms?
Do you go with her to the Dr?
