Over-the-counter fiber supplements are known as cilium or psyllium. Cilium is used to absorb liquid in the intestines helping the stool to bulk up. These supplements are used to treat diarrhea and constipation in addition to helping lower low-density lipoprotein -- bad cholesterol -- levels. These supplements can cause bloating and upset stomach temporarily, but any severe pain while taking them should be reported to your physician.
Common Side Effects
Over-the-counter cilium such as Metamucil or Fiberall can cause mild symptoms such as bloating and changes in bowel movement, according to Drugs.com. Taking the supplement as directed on the package can help minimize these symptoms. Drugs.com recommends that you take cilium with an 8 oz. glass of water and not swallow the powder dry. Swallowing it dry may cause the powder to expand in your throat, which can cause you to choke.
Severe Side Effects
If you experience symptoms such as choking, trouble breathing, severe stomach pain, cramping, nausea or vomiting, constipation that lasts beyond seven days, rectal bleeding and itchy skin rash; stop using your fiber supplement and contact your physician immediately. Also if you develop swelling in the face, lips, tongue or throat in addition to hives and difficulty breathing get emergency care immediately; these are symptoms of a serious allergic reaction.
Considerations
Before using over-the-counter fiber supplements notify your physician if you are taking blood thinners or medications such as demeclocycline, doxycycline, minocycline or tetracycline. Fiber supplements may interact with these medications and possibly other medications. Drugs.com warns that you should notify your physician if you are using any medication before starting fiber supplements.
Safety
No tests have been offered to insure the safety of cilium products on pregnant or breastfeeding women. If you become pregnant while using cilium or you are already pregnant or breastfeeding, should consult with a pharmacist before taking these products.
