Prucalopride: Make a Plan for Mood Changes

A constipation prescription needs a plan for more than bowel movements. Prucalopride, sold as Motegrity, has a US warning about depression, self-harm thoughts and suicidal thoughts or behavior.¹

Discuss your history before the first tablet

MedlinePlus³ describes prucalopride as a medicine that increases movement through the bowel to treat chronic idiopathic constipation. It asks patients to tell the doctor about past or current depression, suicidal thoughts or actions, other mood problems and kidney disease. Bring your prescription, nonprescription medicine and supplement list too.³

You could say: “Before I start, can we review my mood history and decide who I should contact if it changes?” Ask for a daytime number, an after-hours route and the planned review date. Write those beside the medicine name rather than relying on a general appointment reminder.

MedlinePlus³ recommends that family or caregivers know which symptoms need a call, so they can seek help if you cannot. If you want someone involved, choose who that is and share the instructions before treatment.³

What the warning establishes

The label reports mood-related events during trials and after approval, including reports within the first few weeks of starting treatment. It requires monitoring all treated patients.¹

It also says a causal association with increased suicidal thoughts or behavior has not been established. Voluntary post-approval reports come from a population of uncertain size, so their frequency cannot reliably be calculated. A report does not prove the medicine caused an event, and uncertainty about cause does not cancel the stop-and-contact instruction.¹

These are prescribing and patient-guidance sources. This article does not calculate your risk, diagnose a mood disorder or provide a restart schedule.

Know where to seek help

For new or worsening depression or changes in mood or behavior during treatment, MedlinePlus³ advises contacting the doctor right away. Describe what changed and when, without waiting to decide whether it was caused by the tablet.³

NIMH directs people in the United States who are struggling or having suicidal thoughts to call or text 988, or use the Lifeline’s online chat. For a life-threatening situation, call 911. Outside the US, use your local crisis service or emergency number.²

The play

Try this: write the contact plan now

1. List the medicine name, prescribed strength, start date and the clinician managing it.
2. Write the daytime and after-hours contact instructions. Ask what to do about constipation treatment if prucalopride has to be stopped.
3. If you choose a family member or caregiver to help, show them the warning and the contact details.³

Keep treatment notes beside your Belly Clock

Bloated by Dinner, Chapter 4, introduces the Belly Clock: timed notes about bowel movements, belly symptoms, sleep and stress. Keep your prescription date and contact plan beside those entries for the treatment review. The log is preparation for a conversation; mood symptoms needing prompt help should not wait for a completed week of notes. The book does not give a prucalopride restart plan. See the book.
