Constipation: Treatments for constipation include miralax and other osmotic laxatives that bring more fluid into the bowels to encourage a movement, colace (docussate) and mineral oil that lubricate bowel movements, and stimulant laxatives such as Milk of Magnesia that are quick and effective but may cause cramps. Miralax is a relatively gentle option.
