Can antidepressants be taken along with a natural supplement such as St.Johns Wort for Depression?

no defintly dont take the two together. if you look on the information leaflets that come along with the medication off your doctor it will most likely tell you this :0)

St. John's wort appears to act as an SSRI, although extensive studies have not been done. If taken in combination with another SSRI, if can cause a dangerous and potentially fatal 'serotonin syndrome'.

"The symptoms of the serotonin syndrome are: euphoria, drowsiness, sustained rapid eye movement, overreaction of the reflexes, rapid muscle contraction and relaxation in the ankle causing abnormal movements of the foot, clumsiness, restlessness, feeling drunk and dizzy, muscle contraction and relaxation in the jaw, sweating, intoxication, muscle twitching, rigidity, high body temperature, mental status changes were frequent (including confusion and hypomania - a "happy drunk" state), shivering, diarrhea, loss of consciousness and death. (The Serotonin Syndrome, AM J PSYCHIATRY, June 1991)"

Under no circumstances should St. John's wort ever be taken in conjunction with a monoamine oxidase inhibitor (Nardil, Parnate, Marplan, Selegiline)

No- not a good idea
If your not getting the desired results of your dosage please, please talk to your prescribing Physician!!

You can get great answers to questions like this in the books by Dr. Peter Breggin. Check your library, and be sure to ask them about the Inter-library loan system!

No, definitely don't combine the two. Try one or the other. I would try the natural stuff first.
