I take omeprazole, prednisone, lutein, aspirin, triamterene, and atenolol. Do any of these cause constipation ?Omeprazole (Prilosec) is a proton pump inhibitor that stops acid secretion in the stomach. It is used to prevent and treat ulcers in the stomach and intestine and also to treat gastroesophageal reflux disease (GERD). The most common side effects of omeprazole are headache, abdominal pain, nausea, diarrhea, vomiting, and gas. Constipation was reported by 1.5 percent of patients taking omeprazole. Prednisone is a commonly used oral corticosteroid to suppress inflammation and the immune response. It is approved to treat a number of different conditions. According to the package insert, the most common side effects of prednisone are sleep problems, mood changes, acne, dry skin, increased sweating, nausea, stomach pain, and bloating, headache, dizziness, and changes in body shape or location of body fat (especially in face and neck). Constipation is not specifically listed as a side effect of prednisone. Triamterene is a diuretic or water pill used to reduce fluid retention and treat high blood pressure. The most common side effects of triamterene are drug allergy including rash, changes in blood potassium levels, and weakness. Constipation is not specifically listed as a side effect of triamterene. Atenolol is a beta blocker that works to slow the heart rate. It is used to treat high blood pressure and chest pain (angina). The most common side effects of atenolol are tiredness, dizziness, depression, and cold fingers and toes. Nausea and diarrhea have been reported, but not constipation, in patients taking atenolol. Aspirin is a fever and pain reducer as well as a anti-platelet drug that helps prevent blood clots from forming. The most common side effects of aspirin are upset stomach, heartburn, and vomiting. Lutein is a natural antioxidant that is found in green leafy vegetables and egg yolks. Lutein is also available as a dietary supplement that may help maintain healthy eyes and skin. Safety and side effect information on lutein is limited because it is a dietary supplement and not regulated in the same way as prescription drugs. These products are not required to be tested for effectiveness, purity, or safety by the US Food and Drug Administration. No information suggests that lutein causes constipation. This is not a complete list of the side effects associated with the specified medications. Constipation can have many causes and should be discussed with your health care provider.
 Do not stop any medication or change the dose without first talking to your provider. Some lifestyle changes may help relieve constipation including eating more fiber, drinking plenty of fluids, getting regular exercise, and answering the call to use the bathroom. .
