My daughter hasn't taken her 50mg of Zoloft all week and she's feeling dizzy and has had a headache for the past 2-3 days. What Should I do?

How old is she? Why hasn't she been taking her meds? A patient is not supposed to quit Zoloft cold turkey, but wean himself off it (with the doctor's oversight). She's going through withdrawal now.

She needs to call her doctor to let him know she has stopped taking it, and he will probably prescribe a substitute that will work better for her.
