What is the recommended treatment for constipation lasting 3 days?

Treatment for Constipation Lasting 3 Days

For constipation lasting 3 days, the recommended first-line treatment is a stimulating laxative such as bisacodyl 10-15 mg daily to three times daily, with a goal of achieving one non-forced bowel movement every 1-2 days. 1

Initial Assessment and Management

• Rule out impaction, obstruction, and other treatable causes (hypercalcemia, hypokalemia, hypothyroidism, diabetes mellitus, medication side effects) 1
• Discontinue any non-essential constipating medications (antacids, anticholinergics, antidepressants, antispasmodics, phenothiazines, haloperidol, antiemetics) 1
• Increase fluid intake, particularly for those with low fluid consumption 1
• Increase dietary fiber if patient has adequate fluid intake and physical activity 1, 2
• Encourage physical activity and exercise when appropriate 1, 3

Pharmacological Management

First-Line Options:

• Stimulating laxatives: Bisacodyl 10-15 mg daily to TID with goal of one non-forced bowel movement every 1-2 days 1
• Senna (with or without docusate) 2-3 tablets daily-TID 1
• Evidence suggests that stimulant laxatives alone may be sufficient, without the need for stool softeners 1

Second-Line Options (if constipation persists):

• Polyethylene glycol (PEG) 17g daily mixed in 8 ounces of liquid - produces bowel movement in 1-3 days 1, 4
• Rectal bisacodyl suppository (one rectally daily-BID) 1
• Lactulose 30-60 mL BID-QID 1
• Magnesium hydroxide 30-60 mL daily-BID 1
• Magnesium citrate 8 oz daily 1

Management of Severe or Persistent Constipation

• If impaction is present:

  • Administer glycerin suppository ± mineral oil retention enema 1
  • Manual disimpaction may be required (with pre-medication using analgesic ± anxiolytic) 1
  • Tap water enema until clear 1

• For constipation that doesn't respond to standard laxative therapy:

  • Consider methylnaltrexone 0.15 mg/kg subcutaneously every other day (no more than once daily) for opioid-induced constipation 1
  • Consider adding a prokinetic agent such as metoclopramide 10-20 mg PO QID if gastroparesis is suspected 1

Special Considerations

• For opioid-induced constipation: Prophylactic treatment with stimulant laxatives is recommended when initiating opioid therapy 1
• Newer agents for refractory constipation include lubiprostone and linaclotide, particularly for chronic idiopathic constipation 1
• Fiber supplementation should be increased slowly over several weeks to minimize adverse effects like bloating and flatulence 5, 3
• PEG is strongly recommended for chronic idiopathic constipation with moderate certainty of evidence 1

Common Pitfalls to Avoid

• Relying solely on stool softeners without stimulant laxatives - evidence shows this is often ineffective 1
• Using bulk-forming agents like Metamucil alone for opioid-induced constipation - these are unlikely to be sufficient 1
• Failing to address underlying causes of constipation before initiating symptomatic treatment 1
• Long-term use of magnesium-based laxatives should be avoided due to potential toxicity 5
• Methylnaltrexone should not be used in patients with postoperative ileus or mechanical bowel obstruction 1
