With any medication there is always a very small risk of an allergic reaction, although the risk with Telebrix and Readi-Cat Barium is extremely rare. For individuals with a history of allergies, previous allergic reactions, asthma, eczema, a family history of allergy or a previous reaction to a radiology contrast agent, the risk may be slightly increased.
DO NOT USE THIS PREPARATION IF:
- You are on a sodium restricted diet
- You have kidney disease
Step #2: Two days before your examination
(day #1 of prep)
| TIME | INSTRUCTION |
|---|---|
| Morning and noon |
Follow a low residue diet for breakfast and lunch (see Diet Guidlines chart below). After lunch you must have a restricted diet consisting of clear liquids (see Clear Liquids chart below). Drink plenty of fluids throughout the day to avoid dehydration.
After lunch drink half of the 450 ml bottle of Readi-Cat barium (white, chalky tasting liquid) with fruit juice as needed. Save the other half for tomorrow. |
| 5:00 pm | Have a clear liquid dinner.
Take two Bisacodyl tablets. |
| 6:00 pm | Drink the 300ml bottle of Magnesium Citrate Solution. It's best to drink it as quickly as possible rather than slowly sipping it. This will cause you to have repeated loose stools (diarrhea), which is the expected result. It typically works within 30 minutes after drinking the Solution, but may take as long as 3 hours. You just need to be patient. Just remember to stay close to a bathroom. |
| 7:00 pm | Drink 4-8 more cups of 8 oz fruit juice or clear drink until bedtime. |
