What to Do:
In case of overdose, contact a poison control center immediately. The national poison control center number is 1-800-222-1222. Treatment should be supportive and symptomatic. There is no specific antidote.
Drug Interactions
Moderate Interactions
- Drugs that prolong QT interval (theoretical risk, monitor ECG if co-administered)
- Other prokinetic agents (e.g., metoclopramide, domperidone) - potential for additive effects

Special Patient Groups
Pregnancy
Prucalopride may cause fetal harm based on animal studies. Use during pregnancy should only be considered if the potential benefit justifies the potential risk to the fetus. There are no adequate and well-controlled studies in pregnant women.
Trimester-Specific Risks:
Lactation
It is unknown if prucalopride is excreted in human milk. Consider the developmental and health benefits of breastfeeding along with the motherβs clinical need for prucalopride and any potential adverse effects on the breastfed infant from prucalopride or from the underlying maternal condition. Based on its pharmacokinetic properties (low protein binding, high bioavailability, renal excretion), transfer into milk is possible but likely low. Monitor breastfed infants for diarrhea.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients less than 18 years of age. Not recommended for this population.
Geriatric Use
No specific dose adjustment is required based on age alone. However, elderly patients are more likely to have decreased renal function, which necessitates dose adjustment for severe renal impairment. Monitor for adverse effects as elderly patients may be more sensitive.
Clinical Information
Clinical Pearls
- Prucalopride is a good option for chronic idiopathic constipation (CIC) when osmotic laxatives or fiber supplements have been insufficient.
- It is a highly selective 5-HT4 agonist, which contributes to its efficacy and potentially lower side effect profile compared to less selective agents.
- Patients should be advised that while some may experience a bowel movement within 24 hours, the full therapeutic benefit for CIC may take several days or weeks.
- Emphasize the importance of adequate fluid intake and dietary fiber alongside medication for optimal results.
- Counsel patients on potential side effects like headache, nausea, and abdominal pain, which are often transient and resolve with continued use.
- Monitor for new or worsening psychiatric symptoms, including depression and suicidal ideation, as these have been reported in clinical trials.
Alternative Therapies
- Polyethylene glycol (PEG)
- Lactulose
- Lubiprostone (Amitiza)
- Linaclotide (Linzess)
- Plecanatide (Trulance)
- Tegaserod (Zelnorm - for IBS-C in women <65 with no cardiovascular disease)
- Fiber supplements (e.g., psyllium, methylcellulose)
- Stool softeners (e.g., docusate)
- Stimulant laxatives (e.g., bisacodyl, senna - for short-term use)
