Possible drug interaction?

[darklydevoured]

Back in September, I had smoked marijuana and not long after had a reaction. Whole body became tense, then my head would snap to the side. I could talk but had to force words out. Then my right arm fused to my side and hands would curl in violently, painfully. Towards the end there was uncontrollable upward eye movements. I was aware and worried but decently calm during it. I thought it was maybe a buspirone/trileptal/welbutrin reaction re: the marijuana but saw a neurologist just in case. He said he's never heard of a marijuana interaction with my meds like that or even marijuana having that reaction in general. Told me it sounded like dystonia and to take benadryl the next time it happens.

Fast forward to 6/24 (last week). I went in for knee surgery. When I woke up I was still in a bit of pain so the nurse gave me dilaudid. Now, my perception of time during this is off, but not too long after I started having the same kind of jerking sensations as described above. This time it was less violent. My back kept arching and my neck was snapping to the side. Arms twitching. I was calm about it but the staff seemed confused. They gave me ativan and after a little bit, while i was still spasming, I managed to tell them what the neurologist said and they gave me benadryl. I don't know how long it took to stop, but it did. After, in recovery 2, the anesthesiologist came up to me to see how I was doing. Asked me about buspirone and what I was taking it for. It seemed like he wanted me not to take it but didn't say it out right?

I guess my question is, if anyone has had any sort of reactions like this before? I'm not entirely sure what to do with this.

It does sound dystonic. Having a strong urge to look up is an oculogyric crisis. Dystonia would explain the rigidity you had. These are all Extrapyramidal side effects (EPS) which your meds can cause. Pretty common. My money is on buspirone being the cause of EPS, unless you are on other stuff. Cannabis has nothing to do with this.

thank you for the reply! just having an kind idea of what’s going on really helps. hopefully i can avoid other medication triggers while taking the buspirone now. it’s kinda difficult to take the benadryl when your head won’t stop snapping to the side.
