Awoke Gasping For Air After Inhaling Wax Vapour. On Steroids. Family History Of Sleep Difficulty. Worrisome
Thanks for posting your query.
Zantac is not a muscle relaxant; it does not cause any muscle relaxation. It is a H2 antagonist, which inhibits secretion of gastric acid. It is not going to affect the sleep study.
Also, your symptoms are more likely to be due to occupational inhalation of wax vapour.
Zantac may be given to you just as a preparatory measure before the sleep study.
You may continue to take Zantac until the sleep study is completely done.
It is advisable to stop using St. Johns wort as there are no clinical studies that prove its effectiveness. It is not a direct muscle relaxant but can affect the metabolism of other drugs especially pain medications.
I hope to have answered your query. Please do write back in case you have follow up queries to ask.
