Psyllium is a natural, over-the-counter laxative that is available in tablet, capsule and wafer form but is most often simply mixed with water and consumed several times daily. Specific psyllium dosages depend on a variety of factors, including your age, your medical condition and whether or not you have taken psyllium in the past. A number of possible side effects are associated with psyllium use. Speak to your doctor about potential dangers and safe dosage ranges before using any psyllium product.
Psyllium
Psyllium is Plantago ovata, a bushy herb whose seeds and seed husks are used to treat a variety of conditions, including constipation, high cholesterol, hemorrhoids, diarrhea and irritable bowel syndrome. The University of Maryland Medical Center reports that some scientific research indicates that psyllium use may also decrease high blood pressure and colon cancer risk, but more studies and clinical trials are needed before health professionals can recommend the plant's use as a safe and reliable treatment for these problems. Psyllium is sold under several brand names.
Psyllium Laxative Dosage
Psyllium is used as an oral bulk-forming laxative because when it is consumed, its fibers swell with water and form a jelly-like mass within the digestive tract. As this mass moves through the intestines, it stimulates regular contractions and results in bowel movements. According to the National Institutes of Health, adult dosages of psyllium for laxative purposes can range between 7 and 40 g daily taken in up to four divided doses. In powder form, a typical laxative dose ranges between 1/2 to 2 tsp. of psyllium mixed with 8 oz. of lukewarm water, but these amounts may vary if sweeteners or other inactive ingredients are included. If you have never used psyllium, begin with the lowest possible dosage and work up to higher dosages, if needed, over a matter of days. Follow all instructions exactly -- never take more than the recommended dosage, and do not use psyllium regularly for more than seven days unless you are under the direction and supervision of your doctor.
Possible Side Effects
Even in small dosages, psyllium may cause side effects like nausea, bloating, abdominal pain, gas, headaches and sinus problems. More serious side effects -- hives, difficulty breathing, swelling of the lips, face, neck or mouth -- may occur in people who are allergic to psyllium. Psyllium should be avoided by people with digestive system disorders, kidney disease, diabetes or phenylketonuria. Psyllium may also interfere with the proper function of medications like warfarin, carbemazepine, antidepressants such as doxepin, lithium, digoxin, doxycycline and anti-diabetes drugs.
Considerations
If you use psyllium as a laxative, drink plenty of water. Drink 8 oz. of water with each dose and drink at least six cups of water throughout the day. If you do not consume enough water, the psyllium may obstruct your esophagus or intestines. It is also important to not take psyllium longer than your doctor instructs. Long-term psyllium use can cause permanent damage to the nerves and muscles in the intestines. Stop using psyllium and seek medical help immediately if you experience rectal bleeding, severe stomach pain, vomiting or constipation that persists for over a week.
