Had just entonox with a colonoscopy this morning and I am absolutely wiped out!! I've spent the majority of the day sleeping and struggling to feel awake even now and have had a tingliness in my lower lip too and a dry mouth and so thirsty?! Anyone else have that sort of reaction to entonox? I had it once before but was on morphine too so was too blitzed to know what I felt anyway!
You would not be "wiped out" from using Entonox. Entonox is made up of Nitrous Oxide and Oxygen. The nitrous oxide is removed from you body within minutes after you stop inhaling it. It does not stay in your system like other sedatives would - where you would feel the effects for hours after.
I do not know anything about entonox but my autistic child has needed quite a lot of nitrous oxide for dental work and I read that it can depleat Vit B12 stores, so I give him a (sublingual) top up after each visit just in case. Hope you are better today.
