Soluble fiber is an important part of the diet as it helps keep the digestive tract healthy. Psyllium is often used as a source of soluble fiber, particularly in bulk-forming laxatives. Although this compound is generally safe for people to use, there is the potential for psyllium to interfere with some medications or cause health problems when taken improperly.
Identification
Psyllium comes from the Plantago ovata plant, the University of Maryland Medical Center reports. Although this plant grows throughout the world, it is most common in India. Psyllium is derived from the husk which covers the seeds of this plant. Because each Plantago ovata plant can have over 100,000 small seeds, psyllium is often harvested by crushing the seeds and separating out the fiber-filled husks.
Uses
Psyllium is commonly used as an ingredient in laxatives because it cannot be absorbed by the digestive tract. Instead, psyllium absorbs water, forming a soft gel which adds extra volume, bulk and softness to bowel movements. Psyllium can be used to treat constipation and can also be used for people with high cholesterol, as increased dietary fiber can help lower cholesterol in the body.
Side Effects
Although psyllium products and tablets are generally safe, there are some side effects that this soluble fiber can cause. According to PubMed Health, people taking psyllium may experience stomach pain, nausea and vomiting. Taking too much psyllium may also result in diarrhea. Finally, some people are allergic to psyllium and may develop a rash or hives, have difficulty swallowing or experience trouble breathing after taking this product. People who are allergic to psyllium should never consume it, as severe allergic reactions can be life-threatening.
Considerations
People taking psyllium products should not use psyllium for more than one week, Drugs.com explains. Taking psyllium on a regular basis for an extended period of time can cause the digestive tract to change the way it makes fecal material. If this happens, you can become dependent on psyllium to have normal bowel movements which can result in damage to intestinal muscles and nerve tissue.
Drug Interactions
Products which contain psyllium can interact with some medications. For example, people taking antidepressants, carbemazepine, lithium and digoxin may need to adjust their dosage levels if they take psyllium, as psyllium can interfere with the absorption of these drugs. Psyllium can also increase the effects of medications used to treat high blood cholesterol and diabetes. As a result you should let your doctor know before you begin to take psyllium to make sure that it will not cause problems for any medication you are taking.
