Hey everybody, I'm new to bluelight so please bear with me. I question whether my usual kratom dose can be taken concomitantly/concurrently with 5-htp? I only ask because kratom is said to act on the same mu-opioid receptors as tramadol and 5-htp is a precursor to serotonin. I have had a couple of bad experiences because of tramadol interactions - 1 being a seizure accompanied by renal failure and primary pulmonary hypertension when I stayed up late the night before, drank a few, then the following morning took both adderall and tramadol. The second disastrous seizure happened the first day i started an SSRI (paxil) treatment and ignorantly took tramadol the same day. This second seizure was not nearly as bad as the first, for one I was released from the ER a couple hours later with no lingering side effects. But I was hospitalized for the weekend after my first seizure with the kidney failure and the primary pulmonary hypertension (which all went away in a couple of days) I am unsure if adderall produces serotogenic effects and that it's interaction with tramadol (does raise serotonin in the brain) caused serotonin syndrome and the associated side effects ie)seizure. I am almost positive my second seizure was due to serotonin syndrome from mixing an ssri with tramadol as I felt very lightheaded and proceeded to have a syncopal episode (faint) then convulse. Sorry for such a long story but I think the details are important. Does kratom increase serotonin in the brain? Will it cause serotonin syndrome if taken in conjunction with 5-htp? Thank you for your interest.
