Can I take 5htp and Methylphenidate together?

Why this happens

5-HTP is a building block that your body uses to make serotonin. Methylphenidate (often known by brand names like Ritalin or Concerta) primarily increases dopamine, but it also slightly increases serotonin levels. When taken together, these two substances can cause serotonin levels to rise to dangerous levels.

You should avoid taking 5-HTP if you are prescribed methylphenidate. If you are already taking both, do not stop your prescribed medication, but speak to your doctor or pharmacist as soon as possible. Seek immediate medical help if you experience a high fever, seizures, or loss of consciousness.
