What is psyllium?
Psyllium is a bulk-forming fiber laxative. Psyllium works by absorbing liquid in the intestines and swelling to create a softer, bulky stool that is easier to pass.
Psyllium is used to treat occasional constipation or bowel irregularity. Psyllium may also be used to treat diarrhea and may help lower cholesterol when used together with a diet low in cholesterol and saturated fat.
Psyllium may also be used for other purposes not listed in this product guide.
Laxatives may be habit-forming if they are used too often or for too long. This can lead to damage of intestinal nerves or muscle tissues. Do not take psyllium for longer than directed on the label or prescribed by your doctor.
You should not take this product if you are allergic to psyllium, or if you have:
- trouble swallowing;
- a sudden change in bowel habits that lasts longer than 2 weeks;
- severe nausea, vomiting, or stomach pain; or
- if you have ever had a skin rash while taking psyllium.
If you have certain conditions, you may need a dose adjustment or special tests to safely use this product. Before you take psyllium, tell your doctor if you have:
- a colostomy or ileostomy;
- rectal bleeding; or
- a blockage in your intestines.
Psyllium products may contain sugar, sodium, or artificial sweeteners. This may be of concern to you if you have diabetes, high blood pressure, or phenylketonuria (PKU). Check the product label if you have any of these conditions.
FDA pregnancy category B. Psyllium is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether psyllium passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Avoid taking other oral (by mouth) medications within 2 hours before or after you take psyllium. Bulk-forming laxatives can make it harder for your body to absorb other medications, possibly making them less effective.
Avoid breathing in the dust from psyllium powder when mixing. Inhaling psyllium dust may cause an allergic reaction.
If you take psyllium as part of a cholesterol-lowering treatment plan, avoid eating foods that are high in fat or cholesterol. Your treatment will not be as effective in lowering your cholesterol if you do not follow a cholesterol-lowering diet plan.
