Methylcellulose is a bulk-forming laxative that absorbs the fluid in the intestines. This increases the bulk of the stools and makes them softer. Methylcellulose is often used for relieving mild constipation and to promote regular bowel movements. It is available without a prescription, but it may be recommended for use by a doctor. As with any medication, methylcellulose has the potential for side effects.
Common Side Effects
The most common side effect of methylcellulose, according to GiCare.com, is the increase in intestinal gas or bloating. This side effect can be uncomfortable but is usually considered harmless. Increasing fluid intake can reduce the gas and ensure the individual does not experience any other side effects, like dehydration or further constipation. Other possible side effects include diarrhea, loud or more frequent stomach sounds, nausea and mild abdominal cramping.
Serious Side Effects
Severe abdominal cramps or pain, vomiting and trouble swallowing are adverse reactions that should be reported to a doctor, according to GiCare.com. Drugs.com also indicates that rectal bleeding or chest pain are abnormal reactions to methylcellulose.
Allergic Reaction
Some individuals may experience an allergic reaction to the medicine. Drugs.com identifies serious symptoms of allergy as trouble breathing; closing of the throat; swelling of the lips, tongue or face; or hives. These reactions can indicate severe allergy and can lead to anaphylactic shock or death if left untreated.
