taking MetFormin need to take additional precautions after a cardiac catheterization.
It is possible for dye injected during the procedure to affect the function
of your kidneys.
- Do not take your Metformin for three days starting on the day of the procedure.
- Watch your voiding pattern for three days. If your voiding pattern changes
from the usual routine that is normal for you, contact your family physician.
- Monitor your blood glucose level four times a day until it returns to normal.
It may be higher than your normal because of the procedure and stress you
may have experienced. If your blood glucose reading is > 15 seek medical
advice right away.
- Increase your intake of non-carbohydrate containing fluids (water, tea,
coffee, diet soft drinks, artificially sweetened crystal drinks) to assist in
flushing your system of the dye that has been injected during the procedure.
- The physician who ordered your procedure will arrange to have a blood test
done in three days to assess your kidney function. Based on the results of that
test he/she will instruct you when to start your Metformin.
