Do not take 5-HTP if you're taking other medications that increase serotonin levels, such as antidepressants like SSRIs and MAO inhibitors. Use caution when taking carbidopa, a medication for Parkinson's disease.
5-HTP is not recommended for people with Down syndrome, as it has been linked to seizures. Also, do not take 5-HTP less than two weeks before surgery as it may interfere with some medications commonly used during surgical procedures.
5-HTP may interact with other medications as well.
As with any supplement, be sure to check with your doctor before starting something new.
