Administration of Oral Medications in NPO Patients
Oral medications should not be administered to patients who are NPO (nil per os) in the hospital setting, and alternative routes of administration should be used until swallowing is formally assessed and found to be safe. 1
Understanding NPO Status and Medication Administration
NPO status is a medical instruction meaning "nothing by mouth" and is commonly used in hospital settings for various reasons including:
- Preparation for surgical procedures
- Risk of aspiration
- Gastrointestinal issues
- Swallowing difficulties
Key Guidelines for Medication Management in NPO Patients
- Medications should not be administered orally to patients who are NPO 1
- Alternative routes of administration should be utilized when patients cannot take medications orally 1
- A formal swallowing assessment should be completed before resuming oral intake, including medications 1
Alternative Medication Routes for NPO Patients
When a patient is NPO, medications can be administered through alternative routes:
- Intravenous (IV)
- Intramuscular (IM)
- Subcutaneous
- Nasogastric tube (NGT) or other enteral feeding tubes
- Rectal
- Transdermal
- Sublingual (in some cases)
Special Considerations for Specific Patient Populations
Patients with Diabetes
For NPO diabetic patients:
- Basal insulin or a basal plus bolus correction insulin regimen is the preferred treatment 2
- Sliding scale insulin alone (without basal insulin) is discouraged 2
- Blood glucose monitoring should be performed every 4-6 hours in patients who are not eating 2
Patients with Acute Gout
For NPO patients with acute gout:
- Intra-articular injection of corticosteroids is recommended for involvement of 1-2 joints 2
- Intravenous or intramuscular methylprednisolone at an initial dose of 0.5-2.0 mg/kg is appropriate 2
- Subcutaneous synthetic adrenocorticotropic hormone (ACTH) at an initial dose of 25-40 IU is an alternative 2
Patients with Swallowing Difficulties
- Patients with suspected bronchoaspiration or dysphagia should remain NPO until a formal swallowing evaluation is performed 1
- Medications should not be administered orally until swallowing has been formally assessed and found to be normal 1
Common Pitfalls and How to Avoid Them
Inappropriate medication administration:
Lack of standardized guidance:
Medication errors with nasogastric tubes:
Nutritional compromise:
Decision-Making Algorithm for Medication Administration in NPO Patients
- Confirm NPO status and reason (surgical preparation, aspiration risk, etc.)
- Review each medication for:
- Clinical necessity during NPO period
- Available alternative routes
- Potential to hold temporarily
- For essential medications:
- Convert to parenteral form if available
- Consider transdermal or other non-oral routes
- Consult pharmacy for appropriate alternatives
- Document all medication changes and rationale
- Reassess NPO status daily and resume oral medications when appropriate and safe
By following these guidelines, healthcare providers can ensure patient safety while maintaining necessary medication therapy during periods when oral intake is restricted.
