Study Notes
Prescriptions and Medication Orders
- Prescriptions are utilized in outpatient settings, while medication orders are used in inpatient or institutional settings.
- Both serve as legal orders for medications, devices, laboratory tests, and procedures.
- Prescriptions can be handwritten, typed, preprinted, verbal, or electronically submitted through fax or computer systems.
Over-the-Counter vs. Legend Drugs
- Over-the-counter medications are deemed safe for public use without prescriptions by the FDA.
- Legend (prescription) drugs require supervision from a licensed practitioner for safe administration.
Pharmacist's Responsibilities
- Before dispensing, pharmacists must evaluate prescriptions for appropriateness, ensuring correct drug, dose, frequency, route, duration, and indication.
- Patient profiles are assessed for therapeutic duplication, drug allergies, drug-disease interactions, and drug-drug interactions.
- Reviewing available laboratory data helps maximize therapy benefits while minimizing risks.
Information Required on Prescriptions
- Typical prescription information includes:
- Patient's name
- Drug name, strength, and dosage form
- Quantity prescribed
- Directions for use
- Prescriber's name, address, and signature
- Additional details may include:
- Date of issue
- Number of authorized refills
- Patient’s address or date of birth
- Prescriber’s DEA registration number
- Stricter regulations apply to prescriptions for scheduled or controlled substances.
Pediatric and Veterinary Prescriptions
- Pediatric prescriptions must include patient age and weight.
- Veterinary prescriptions require the animal species information.
Medication Orders
- Similar information as a prescription, but also includes:
- Secondary patient identifier (e.g., date of birth, medical record number)
- Patient location and room number
- Date and time of the order
DEA Registration for Controlled Substances
- Providers prescribing controlled substances must register with the DEA and obtain a registration number.
- The DEA number consists of two letters followed by seven numbers, e.g., AF1234563.
- First character of the DEA number is 'A' or 'B' for prescribers, and 'M' for mid-level practitioners (PAs, NPs).
- The second character corresponds to the first letter of the prescriber’s last name.
Verification of DEA Numbers
- The validity of a DEA number can be mathematically verified:
- Sum the odd-numbered digits (1st, 3rd, 5th).
- Sum the even-numbered digits (2nd, 4th, 6th) and multiply by 2.
- Add both results.
- The last digit of this sum should match the 7th digit of the DEA number.
