I had to use Dantrium 20mg IV for the first time last week after a severe muscle spasm that threatened to send me into malignant hyperthermia. It was intense, but the IV injection helped control the tightness and my overall temperature. I'm curious if anyone else has had a similar experience, especially regarding the side effects. Did anyone feel choking sensations, or were there other side effects that I should know about?
