How GlycoLax Works
Polyethylene glycol 3350 helps retain water in the stool. This softens stool and makes it easier to pass. A bowel movement may take two to four days, so it does not work as quickly as a rectal suppository.
How to Take GlycoLax
Measure the dose as directed on the product or by your clinician. Dissolve the powder in a beverage before drinking it. Do not take more or use it longer than directed.
Possible Side Effects
Nausea, bloating, gas, and abdominal cramps may occur. Diarrhea or hives warrants medical advice. Seek guidance before use if you have signs of a bowel blockage, such as vomiting, severe abdominal pain, or marked bloating.
When to Seek Medical Advice
Contact a clinician if constipation continues despite treatment. Report rectal bleeding or a significant change in bowel habits. A clinician can assess whether another condition or medicine is contributing to the problem.
