Bulking fiber can delay absorption of oral drugs and dicyclomine can worsen constipation in some patients.
Every entry follows the same shape: what is happening, the mechanism, and the recommendation.
What is happening. Bulking fiber can delay absorption of oral drugs and dicyclomine can worsen constipation in some patients.
Mechanism. Fiber gel formation can physically delay drug dissolution and transit while anticholinergic therapy slows motility.
Recommendation. Separate psyllium and dicyclomine by at least 2 hours and increase fluids if fiber is used.
Space the doses apart by at least this window to avoid the conflict.
