If you are not taking an anti-depressant or anti-anxiety drugs, 5-HTP has no contra-indications. Your doc will probably not know what to do with it. It is a naturally occurring substance in your body. L-Tryptophan becomes 5-HTP which becomes serotonin and melatonin.

My progressive doctor/psychiatrist helped me transition off an SSRI to L-Tryptophan and 5-HTP.

If you doctor does not support it, there is no reason you cannot try it on your own. Just start with the low dose. I start every day with 100 mgs of 5-HTP. I'm a mess without it.
