Combining serotonergic drugs such as antidepressants, dextromethorphan (in cough syrups), meperidine (Demerol), tramadol and others may increase the risk of serotonergic side effects such as serotonin syndrome.

Combining 5-HTP and carbidopa-levodopa (Sinement®) can increase the risk of serotonergic side effects.

Carbidopa is sometimes intentionally used with 5-HTP to minimize peripheral 5-HTP metabolism and boost the amount that reaches the brain. But this combination might also increase the risk of some side effects including hypomania, restlessness, rapid speech, anxiety, insomnia, and aggressiveness.

The combination of 5-HTP and carbidoba has also resulted in scleroderma-like skin reactions. Individuals using this drug combination or those who suffer from scleroderma should be monitored by a health care practitioner.

Anecdotally, 5-HTP may lower blood pressure and could be additive to antihypertensive drugs.
