Answer

Because no convincing reason exists to pick one product over another, a single brand of choice should be prescribed until the patient’s constipation resolves. The patient may then switch to generic or other brands with appropriate dose adjustments.

The author’s experience has been that some patients have preferences based on the taste of the product or other subjective reasons. In particular, those rare patients who cannot tolerate fermentable fiber supplementation because of resulting gas or bloating may do better with methylcellulose, whereas others may find that the quality of the stool, taste preferences, or both favor psyllium supplementation.
