Duplicate inhaler prescriptions for asthma and COPD are rare, affecting about 1% of patients. Combination inhalers were more frequently duplicated than single medications, highlighting a need for prescriber and pharmacist awareness.
Area of Science:
- Respiratory Medicine
- Pharmacotherapy
- Drug Safety
Background:
- Inhalative treatments are crucial for asthma and COPD management.
- Numerous new single and combination inhaler products have been introduced.
- Physician surveys suggested a high likelihood of duplicate prescriptions.
Purpose of the Study:
- To investigate the prevalence of duplicate inhaler prescriptions.
- To identify patterns in duplicate prescription occurrences.
Main Methods:
- Analysis of a large mail-order pharmacy database.
- Identification of duplicate inhaler prescriptions within a 3-month period.
- Distinction between same-physician and different-physician duplicates.
Main Results:
- Duplicate prescriptions were unexpectedly rare, around 1%.
- Combination inhaler duplicates were more common than monotherapy duplicates.
- Thousands of erroneous prescriptions were noted despite the low percentage.
Conclusions:
- Duplicate inhaler prescriptions are relatively uncommon in this mail-order pharmacy setting.
- Prescribers and pharmacists must remain vigilant regarding duplicate prescriptions, especially for combination products.
