General Info:

Colace is for short-term relief only, unless your doctor directs otherwise. It usually takes a day or two for the drug to achieve its laxative effect; some people may need to wait 4 or 5 days. Sof-Lax Overnight works in 6 to 12 hours. Colace Microenema works in 2 to 15 minutes.

Colace, a stool softener, promotes easy bowel movements without straining. It softens the stool by mixing in fat and water. Colace is helpful for people who have had recent rectal surgery, people with heart problems, high blood pressure, hemorrhoids, or hernias, and women who have just had babies. Colace Microenema is used to relieve occasional constipation.
