Tryptophan Drug Interactions

You should have few problems if you take other medications, although a few complications have been noted.

Tryptophan can "interact" with "MAOIs" and the "SSRIs" (e.g. citalopram ['Cipramil'], fluoxetine ['Prozac'], fluvoxamine ['Faverin'], paroxetine ['Seroxat'], sertraline ['Lustral']) although your doctor should know about these.

This does not necessarily mean the drugs cannot be used together, just that you may need to follow your doctors instructions very carefully. Make sure your doctor knows about all the medicines and dietary supplements you are taking.

Some other medicines e.g. antihistamines can make you drowsy. Combined with your tryptophan this could make you even drowsier. There has been much concern about the safety of St. John's wort with antidepressants. Until more information is available, you should avoid taking St. John's wort along with any other antidepressant.

You should tell your doctor before starting or stopping these or any other drugs.
