What happens when you stop taking amitiza?

Amitiza (lubiprostone) helps increase fluid in the intestines to treat constipation/IBS‑C. What happens when you stop it depends on why you’re taking it, how long you’ve been on it, and your underlying bowel problem.

Common things that may happen after stopping

• Constipation can return: Many people start having fewer bowel movements, harder stools, and more straining again.
• IBS‑C symptoms may come back (if that was the reason you were prescribed it): such as bloating, discomfort, and irregular stools.
• Stool/comfort changes may occur within days: since it works locally in the gut, symptoms often return as the effect wears off.

Usually not “withdrawal”

Amitiza is not typically associated with classic drug withdrawal (like seizures, severe agitation, etc.). Instead, it’s more about loss of the medication’s effect.

Possible severity

• For some people, symptoms are mild and gradually improve once they restart or manage with other measures.
• For others, constipation can become quite uncomfortable—especially if there’s an underlying chronic motility issue.

Practical next steps

• Don’t stop abruptly without a plan if you’re having severe symptoms, because you may need an alternative approach.
• If you’re stopping because of side effects, ask your prescriber about dose adjustment or a different constipation/IBS‑C therapy.
• If needed, constipation management often includes fiber/fluids, osmotic laxatives (like polyethylene glycol), and lifestyle changes—your clinician can tailor this.

Get urgent help if

Stop and seek medical care promptly if you have:

• severe/worsening abdominal pain
• vomiting
• blood in stool
• no bowel movement with significant bloating
• fever or feeling very unwell

If you tell me why you’re taking Amitiza (IBS‑C, chronic idiopathic constipation, etc.), your dose, and how long you’ve been on it, I can give a more specific idea of what to expect after stopping and what alternatives might help.
