If your daughter tapers off the antidepressants or quits cold turkey it will result in severe anxiety at about one week after the last dose. To lessen this effect get her to take Omega Joy fish oil every day while still taking the meds. Omega Joy (Genuine Health) or Omega Mood (Quest) is pure EPA (1000mg of EPA and no DHA was shown to alleviate major depression and anxiety in studies). DHA is more for attention deficit. Look up Dr Logan studies on EPA for depression.
My orthomolecular M.D. got me on Omega Joy while I was tapering off of Wellbutrin and the withdrawal was much less than when I tried to taper off previous to that. This was 2005. I still take my 2 caps of Omega Joy with supper every night. The studies showed 1000mg of EPA worked as well or better than meds and some groups were taking meds with it no side effects. Just made the meds work better.
Since iodine detoxifies poisons from the body, maybe it would decrease the effects of the meds. (?)
