USP 800 (Hazardous Drug Handling)

PTCB

Definition

Standards for safe hazardous drug handling: receiving, storage, compounding, administration, disposal.

Clinical Significance

Pharmacy technicians must understand how usp 800 (hazardous drug handling) connects to medication therapy. For example, Insulins (lispro (rapid), regular (short), NPH (intermediate), glargine (long)): Replaces endogenous insulin, facilitates glucose uptake into cells.

Hypoglycemia
Weight gain
Lipodystrophy at injection sites
Never mix glargine with other insulins

Exam Focus Areas

On the Ptcb exam(s), questions about usp 800 (hazardous drug handling) typically test:

Drug interactions and contraindications that affect patient safety
Mathematical calculations: dosage, days supply, dilutions, and compounding
Federal and state regulations governing practice
Drug classification, mechanism of action, and common side effects

Related Procedures

Standards for safe hazardous drug handling: receiving, storage, compounding, administration, disposal. PPE requirements, engineering controls, and spill management tested on PTCB exam.

Related drug class: Fluoroquinolones includes ciprofloxacin, levofloxacin, moxifloxacin. Mechanism: Inhibit bacterial DNA gyrase and topoisomerase IV, bactericidal.

Workplace Applications

In daily practice, usp 800 (hazardous drug handling) is applied consistently according to facility protocols and current evidence-based guidelines. Competency is maintained through annual skills validation, continuing education, and quality improvement participation.

Calculation Methods

Calculations relevant to usp 800 (hazardous drug handling) in pharmacy:

days supply: quantity dispensed / (dose * frequency). Example: #90 tabs, 1 tab TID = 90/(1*3) = 30 days

body weight dosing: dose (mg/kg) * weight (kg) = total dose. Example: Vancomycin 15mg/kg * 80kg = 1200mg

Regulatory Context

Regulatory framework for usp 800 (hazardous drug handling) in pharmacy:

Schedule II: High abuse potential with accepted medical use. Examples: oxycodone, fentanyl, morphine, amphetamine, methylphenidate. Storage: Double-locked, perpetual inventory, no refills, written/electronic Rx only
Schedule III: Moderate abuse potential. Examples: testosterone, ketamine, Tylenol with codeine. Storage: 5 refills in 6 months, written/oral/electronic Rx
Schedule IV: Low abuse potential relative to III. Examples: benzodiazepines, zolpidem, tramadol. Storage: 5 refills in 6 months

Why It Matters

PPE requirements, engineering controls, and spill management tested on PTCB exam.
