What is the recommended step-by-step medication ladder for treating constipation in adults over 60?

✓ Accepted answer

The recommended medication ladder for adults over 60 begins with osmotic laxatives, followed by stimulant laxatives, and finally secretagogues, all under the guidance of a healthcare professional.

• Step 1: Osmotic Laxatives. Start with polyethylene glycol (PEG) combined with electrolytes, such as MiraLAX or Laxative-7. A typical dose is 17 grams daily, which can be adjusted to twice daily if necessary. This is preferred first because it is safe for long-term use and has a lower risk of electrolyte disturbances compared to other options.
• Step 2: Stimulant Laxatives. If osmotic agents fail, add a stimulant like senna or bisacodyl. Senna is often used at 8.6 mg to 17.2 mg twice daily. In the UK, this may involve combining a simple stimulant with the patient's existing regimen. Avoid long-term daily use of stimulants without medical supervision to prevent dependence.
• Step 3: Secretagogues and Specialized Therapies. For refractory cases, doctors may prescribe linaclotide or lubiprostone. These medications stimulate fluid secretion into the bowel. In the UK, the National Institute for Health and Care Excellence (NICE) provides specific pathways for these advanced treatments.
• Review Polypharmacy. Before escalating, audit all current medications. Drugs like calcium channel blockers, opioids, and iron supplements are major contributors to constipation in seniors. A pharmacist can help identify and adjust these causes.
• Hydration and Fiber. Medications only work if you drink enough water. Aim for at least 1.5 to 2 liters of fluid daily. Adding fiber is only effective if fluid intake is sufficient; otherwise, it can worsen bloating and impaction.
