I had a virtual Colonoscopy for which I had to drink three 50ml bottles of Omnipaque 350 with 2 sachets of Movicol the day before the procedure, then another intravenous dose of Omnipaque on the day of the scan. Nearly 4 weeks after this I then had very sore lips and a rash around my mouth. I went to my doctor and she told me to use coconut oil. However, a week later the rash has spread around my face and nose and after another few days it has spread to the rest of my face and neck. It is very itchy! Has anyone else had this type of reaction?

Dx: prostate cancer getting CT of abd/pelvis, need to take omnipaque as oral prep what side effects should I expect ## Hi Hardy, The most frequently reported adverse reactions with Omnipaque are headache, mild to moderate pain including backache, neckache and stiffness, nausea, and vomiting. These reactions usually occur 1 to 10 hours after injection, and almost all occur within 24 hours.

Thanks ## It has been known to cause what's described as 'various GI disturbances', so diarrhea really isn't too surprising. Learn more Omnipaque details here. I don't remember what contrast agent was used when I has one done, but I did have diarrhea for awhile afterwards, as well. I was able to take some over the counter Imodium to clear it u...
