What Psyllium is used for

  • Constipation
  • Mild cholesterol lowering as part of diet
  • Helping stool consistency in some diarrheal conditions

◆ Kidney note

Fluid allowances in dialysis may limit its use, since each serving needs a full glass of water.

Common side effects

  • Gas and bloating
  • Stomach fullness

Important cautions

  • Must be taken with a full glass of water — swelling dry in the throat can cause choking, and it is avoided in swallowing problems
  • Can reduce absorption of medicines taken at the same time — separate the timing

How it comes

Powder, capsules, wafers. This guide lists forms only — it never lists strengths or doses.
