Overview 

Dispensing prescriptions is a core pharmacy function that requires precision, clinical judgment, and strict adherence to regulatory standards. Every step—from data entry to final verification—plays a critical role in: 

• Ensuring the correct medication reaches the correct patient  
• Preventing medication errors  
• Supporting positive patient outcomes  
• Maintaining compliance with federal and state requirements  

A structured and consistent workflow is essential to ensure safety and efficiency. 

 
 

Prescription Validation 

Before dispensing, prescriptions must be confirmed as: 

• Legitimate and valid  
• Issued by an authorized prescriber  
• Appropriate for the patient’s condition  

Pharmacists are responsible for ensuring prescriptions meet all legal and clinical requirements prior to processing. 

 
 

Data Entry and Patient Profile Management 

Accurate data entry is essential for safe dispensing and insurance processing. 

Key steps include: 

• Verifying patient identity:  
  • Confirm date of birth before entering data  
• Maintaining a complete patient profile:  
  • Demographics  
  • Allergies  
  • Current medications  
  • Insurance information  
• Entering prescription details accurately:  
  • Drug name, strength, directions, quantity  

 

Days’ Supply Accuracy 

Correct calculation of days’ supply is critical for: 

• Insurance compliance  
• Refill timing  
• Audit accuracy  

Special attention is needed for: 

• Inhalers  
• Injectables (e.g., insulin)  
• Topicals and ophthalmics  
• Kits and variable-dose medications  

 
 

Generic Substitution and DAW Codes 

Pharmacies may substitute generic medications when appropriate. 

• Generic substitution is permitted unless:  
  • Prescriber indicates “brand medically necessary”  
  • Patient requests brand (where allowed)  
• DAW (Dispense As Written) codes must be:  
  • Accurately selected  
  • Properly documented  

Key considerations: 

• Cost savings should be passed to the patient  
• Professional fees must remain consistent regardless of product dispensed  

 
 

Insurance Processing and Overrides 

During claim adjudication: 

• Technicians may resolve routine claim rejections  
• Pharmacists must review:  
  • Drug utilization review (DUR) alerts  
• Override codes:  
  • Must be used appropriately  
  • Must be documented  
  • Should never be abused  

 
 

Prescription Labeling and Documentation 

After data entry: 

• Ensure inclusion of:  
  • Medication guides and monographs  
  • Required notices (e.g., Medicare notices when applicable)  
• Place completed labels with the prescription for filling  

Best practice: 

• Use one basket per patient to reduce risk of mix-ups  

 
 

Filling Prescriptions 

Accurate filling procedures are critical to prevent dispensing errors. 

 

General Practices 

• Use barcode verification when available  
• Match product NDC with prescription details  
• Include all required materials for verification  

 

Tablets and Capsules

• Special handling:  
  • Use designated trays for allergenic drugs  
  • Use separate trays for hazardous drugs  
• Ensure:  
  • Correct quantity  
  • Proper vial size  
  • Appropriate auxiliary labels  

 

Liquids

• Follow manufacturer instructions (e.g., shaking if required)  

 

Manufacturer Packaging

Pharmacist Verification 

No prescription may be dispensed without final pharmacist verification. 

Verification includes: 

• Accuracy of drug, strength, and quantity  
• Appropriateness for the patient  
• Completion of clinical checks (e.g., DUR)  

The system should document: 

• Identity of the verifying pharmacist  

 
 

Patient Pickup and Counseling 

At pickup: 

• Confirm patient identity:  
  • Date of birth and/or address  
• Complete point-of-sale procedures  
• Offer counseling as required  

Additional steps: 

• Obtain signature and payment  
• Follow ID requirements for applicable prescriptions  

 
 

Reconstitution of Medications 

For medications requiring mixing: 

• Reconstitute according to manufacturer instructions  
• Typically performed at time of pickup  
• Use appropriate diluent (e.g., distilled water if required)  

Key steps: 

• Shake thoroughly during preparation  
• Provide appropriate dosing devices  
• Educate patient on:  
  • Storage requirements  
  • Beyond-use date  

 
 

Dispensing Records
