The three major osmotic laxatives are Miralax, lactulose, and milk of magnesia.
A stimulant laxative is generally recommended as a short-term treatment for constipation.
However, they have different compositions.
MiraLax(a hyperosmotic laxative), increases water in the intestines so stools can exit more rapidly.
The active ingredient in MiraLax is polyethylene glycol (PEG) 3350.
It is an FDA-approved OTC short-term treatment of occasional constipation in those 17 and older.
It can be taken once per day and for no more than seven days.
The active ingredient in milk of magnesia is magnesium hydroxide.
This medication is used for other purposes (e.g., heartburn, upset stomach).
Used as a laxative, milk of magnesia should produce a bowel movement within 30 minutes to six hours.
Do not use milk of magnesia for longer than seven days without medical supervision.
Milk of magnesia should be shaken well before use and can be taken with a glass of water.
There is limited evidence to support the effectiveness of stool softeners in relieving constipation.
Most stool softeners contain a medication called docusate.
