Question: Xanax & L-Tryptophan

 biostockman - Mon Apr 18, 2005 8:44 pm

I am a 27 y.o. male who has been prescribed Xanax 0.5 mg per day for anxiety brought on since quitting smoking. I recently read positive things regarding L-Tryptophan for people with anxiety. My goal is to get off of Xanax and to take L-Tryptophan. But until then I would like to begin taking L-Tryptophan with my other daily supplements. Are there any side effects of taking both other than increased drowsiness that I need to be aware of?

If tryptophan is taken with drugs in the benzodiazepine or phenothiazine classes, symptoms that resemble Parkinson's disease may result. Benzodiazepines such as alprazolam (Xanax) and diazepam (Valium) are usually used to treat anxiety. Phenothiazines such as chlorpromazine (Thorazine), prochlorperazine (Compazine), thioridazine (Mellaril), and trifluoperazine (Stelazine) may be used to treat mental disorders or vomiting. Parkinson's-like symptoms may include muscle stiffness, the inability to move quickly, and trembling.
