What is the maximum dosage for Colace stool softener at one time?

I took 400 mg at one time. I have chronic constipation and nothing works except for magnesium citrate. I don't have a bowel movement unless I use magnesium citrate because the Colace doesn't work. I don't use magnesium citrate every day, only to prevent my poo from backing up too long. I was told that if the poo backs up too far and reaches the other end of my colon such as the appendix that all of my organs will shut down. Is this true? I don't want to die from not being able to have a bowel movement. Any answers or suggestions would be helpful. Thanks. ·

The maximum adult dose of Colace is 400mg daily - either as one dose or in divided doses.

It sounds as though you are suffering from chronic constipation. Have you talked to your doctor about this? Prolonged, excessive use of laxatives can make your constipation worse as your gut can become reliant on the laxative. Excessive use of laxatives can also cause diarrhoea and fluid imbalance which can damage your kidneys.
