Can Dicyclomine Cause Constipation?

Dicyclomine is a medication prescribed for irritable bowel syndrome (IBS) symptoms, such as abdominal cramps and spasms. It works by relaxing the muscles in the stomach and bowel. Constipation is a common side effect, expected due to how the drug functions.

Dicyclomine’s Impact on the Digestive System

Dicyclomine is an anticholinergic (antispasmodic) medication. It blocks acetylcholine, a neurotransmitter that plays a crucial role in stimulating muscle contractions throughout the body, including the digestive tract. This blocking action helps to relax the smooth muscles in the intestines, which reduces the painful spasms associated with IBS.

By inhibiting acetylcholine, dicyclomine directly impacts peristalsis, the wave-like muscle contractions that move food and waste through the digestive system. When these contractions are slowed, the passage of stool through the colon becomes sluggish. This reduced intestinal motility allows more water to be reabsorbed from the stool, resulting in harder, drier, and more difficult-to-pass bowel movements, leading to constipation.

Addressing Constipation from Dicyclomine

Constipation from dicyclomine can cause infrequent bowel movements, difficulty passing stool, or the production of hard stools. Abdominal discomfort, gas, and bloating may also accompany these symptoms. Managing this side effect often involves lifestyle adjustments.

Increasing dietary fiber intake is a helpful strategy, as fiber adds bulk to stool and helps it move more easily through the intestines. Include foods like fruits, vegetables, and whole grains. Adequate hydration is also important, as drinking plenty of water helps to soften stools, making them easier to pass. Regular physical activity can further promote bowel regularity by stimulating intestinal movement.

Over-the-counter options like stool softeners or bulk-forming laxatives may offer relief. Stool softeners work by allowing more water to penetrate the stool, while bulk-forming laxatives absorb water to create a larger, softer stool. Before starting any new over-the-counter medication, consult a healthcare provider.

When to Consult a Healthcare Provider

Contact a healthcare provider if constipation becomes severe, persistent, or causes significant discomfort. Watch for new or worsening symptoms such as intense abdominal pain, severe bloating, nausea, or vomiting. Blood in the stool or an inability to pass gas also warrants immediate medical attention.

If home remedies do not relieve constipation, or if you have concerns about the medication’s side effects, seek medical advice. Never stop taking dicyclomine or alter your prescribed dosage without first consulting your doctor, as this could lead to original symptoms returning or other complications. Your healthcare provider can assess your condition and recommend adjustments to your treatment plan.
