If that is not helping, try bulk-forming laxatives and stool softeners (emollient laxatives) which are generally safer for long term use before taking magnesium citrate.

From the afternoon a day before the procedure, bowel-clearing substances like magnesium citrate or combined with laxative bosacodyl (Dulcolax) then need to be taken. Drink only clear liquids and take no solid food or milk products until procedure is done.
