What is Psyllium?
Psyllium is a bulk-forming fiber laxative that is used to treat occasional constipation or bowel irregularity.
Psyllium may also help lower cholesterol when used together with a diet low in cholesterol and saturated fat.

Warnings
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
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.
Store at room temperature away from moisture and heat. Keep the container tightly closed when not in use.

Before Taking
You should not take psyllium if you have ever had an allergic reaction to it.

This medicine may contain sugar, sodium, or phenylalanine. Check the medication label if you have diabetes, high blood pressure, phenylketonuria (PKU), or if you are on a low-salt diet.
Ask a doctor before using this medicine if you are pregnant or breastfeeding. Your dose needs may be different during pregnancy or while you are nursing.
Do not give psyllium to a child younger than 6 years old without medical advice.
What happens if I miss a dose?
Since psyllium is used when needed, you may not be on a dosing schedule. Skip any missed dose if it's almost time for your next dose. Do not use two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
What special dietary instructions should I follow?
To prevent constipation, drink plenty of fluids, exercise regularly, and eat a high-fiber diet, including whole-grain (e.g., bran) cereals, fruits, and vegetables.
What should I avoid while using Psyllium?
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 high in fat or cholesterol or your overall treatment will not be as effective.
