How should I take psyllium?
Use exactly as directed on the label, or as prescribed by your doctor.
Laxatives may be habit-forming if they are used too often or for too long.
Psyllium can swell in your throat and cause choking if you don't take it with enough liquid. Drink plenty of fluids each day to help improve bowel regularity.
Take psyllium with a full glass (at least 8 ounces) of water or other liquid.
Swallow psyllium capsules one at a time.
Psyllium powder must be mixed with liquid before you take it. Do not swallow the dry powder. Mix with at least 8 ounces of liquid such as water or fruit juice. Stir and drink this mixture right away. Add a little more water to the glass, swirl gently and drink right away.
Psyllium usually produces a bowel movement within 12 to 72 hours.
Do not take psyllium for longer than 7 days in a row without a doctor's advice. Using a laxative too often or for too long may cause severe medical problems with your intestines.
Call your doctor if your symptoms do not improve, or if they get worse.
Psyllium may be only part of a complete program of treatment that also includes diet, exercise, and weight control. Follow your doctor's instructions very closely.
