psyllium hydrophilic muciloid psyllium hydrophilic muciloid

 
  Pronunciation: sill-ee-yum hi-druh-fil-ick mew-sill-oyd  
  Why would this drug be used?
Psyllium hydrophilic muciloid is used to prevent and treat constipation. In some cases, doctors recommend higher doses to help reduce cholesterol, or to help with diarrhea. You can buy it over the counter, without a prescription. 		 
  How does this drug work?
Psyllium hydrophilic muciloid is a bulk-producing laxative made of plant fiber. It absorbs water and expands in the intestines. This stimulates the normal forward movement of the intestines (peristalsis), usually resulting in a bowel movement within 12 to 24 hours. In some individuals, it may take 2 to 3 days. 		 
  Before taking this medicine

Tell your doctor: 		 
 
  • If you are allergic to anything, including medicines, dyes, additives, or foods.
  • If you have nausea, vomiting, rectal bleeding, unexplained abdominal pain, or any disease of the stomach or intestine. Something besides constipation may be causing your problem, and laxatives may worsen it.
  • About any other prescription or over-the-counter medicines you are taking, including vitamins and herbs.
  
  Interactions with other drugs
Bulk-forming laxatives will keep tetracycline (an antibiotic) from working.

Do not take digoxin (heart medicine), nitrofurantoin (an antibiotic), or aspirin products within 3 hours of taking psyllium.

Other medicines may not work as well if taken at the same time as laxatives. Do not take psyllium within 2 hours of other medicines.

Check with your doctor, nurse, or pharmacist about other medicines, vitamins, herbs, and supplements, and whether alcohol can cause problems with this medicine.

  
  Interactions with foods
No serious interactions with food are known at this time. Check with your doctor, nurse, or pharmacist about whether foods may be a problem. 		 
 
Tell all the doctors, dentists, nurses, and pharmacists you visit that you are taking this drug.

  
  How is this drug taken or given?
Psyllium hydrophilic muciloid is given by mouth. Mix the powder in 8 oz of juice or water and drink it right away. Otherwise it will get too thick to drink. Take psyllium wafers in small bites, chew thoroughly, and drink at least 8 ounces of liquid along with them. The dose is the same for all adults, but the number of doses depends on how well it works for you. Take this drug exactly as directed by your doctor, or follow the directions on the label. If you do not understand the instructions, ask your doctor or nurse to explain them to you. Keep the medicine in a tightly closed container away from heat and moisture and out of the reach of children and pets. 		 
  Precautions
Psyllium hydrophilic muciloid is not absorbed by the intestinal tract, so there are few side effects. However, some forms of psyllium may contain sugar. If you have diabetes, check with your pharmacist to be sure you get the powder without sugar.

If you are on a low-sodium diet, check the sodium content or ask your pharmacist before you buy psyllium.

Never try to swallow psyllium powder or granules in dry form. Always mix powdered forms with liquid and take as directed on the package. Take wafers with plenty of water or juice. Drinking extra fluids will help psyllium work better and reduce the chance of blocking the esophagus or intestine. Call your doctor if you have vomiting, abdominal pain, bleeding, or no bowel movement after 3 days.

Call your doctor right away if you have a skin rash or welts (hives), itching, or trouble breathing or swallowing (lump in the throat).

Avoid inhaling the powder when mixing a dose. It can raise your risk of allergic reactions.

To prevent constipation, try to drink 2 to 3 quarts of fluid a day, increase the amount of fruits and vegetables in your diet (5 servings of fruits and vegetables daily), eat bran cereal, and do gentle exercise as tolerated.
