Garbing Procedures

PTCB

Definition

PPE sequence for sterile compounding per USP 797.

Historical Context

Pharmacy regulation in the U.S. began with the Pure Food and Drug Act of 1906. The Federal Food, Drug, and Cosmetic Act of 1938 required proof of safety. The 1962 Kefauver-Harris Amendment added efficacy requirements. Understanding garbing procedures within this regulatory history helps pharmacy technicians appreciate why current standards exist, as each major regulation was prompted by a public health crisis.

Common Errors

Frequent errors with garbing procedures in pharmacy practice:

  1. Misreading sig codes. For reference: PR = rectally; PC = after meals; PO = by mouth; QHS = at bedtime; TOP = topically; TID = three times daily
  2. Calculation errors in dosage. Always double-check units (mg vs mcg, mL vs L)
  3. Wrong DEA schedule classification affecting storage and dispensing requirements

What calculations are involved in garbing procedures?▼
For garbing procedures: percentage strength: w/v: g/100mL, w/w: g/100g, v/v: mL/100mL. Example: 2% hydrocortisone cream = 2g HC per 100g cream.
What drug interactions should be monitored for garbing procedures?▼
For garbing procedures: Opioids (morphine, hydrocodone, oxycodone, fentanyl, codeine): Constipation (tolerance does NOT develop); Respiratory depression; Dependence/addiction; Naloxone reversal. Always check for drug interactions before dispensing.
What DEA schedule considerations apply to garbing procedures?▼
For garbing procedures: Schedule V: Lowest abuse potential (pregabalin, some cough syrups with codeine). Schedule IV: Low abuse potential relative to III (benzodiazepines, zolpidem, tramadol).
