Generic Drug

Generic Drugs have similar efficacy and safety to trade name drugs despite lower cost and different manufacturers
1. Concerns about specific Medication Safety may be submitted to local pharmacist or to FDA
2. Most Generic Drugs are produced by manufacturers other than the brand/trade product
3. "Authorized Generics" are identical to brand/trade name and produced by the same manufacturer
  1. Packaging and medication appearance often differs from the trade product
Historically U.S. Generic Drugs have been held to a high standard of equivalence and safety
1. However, FDA staffing cuts since 2024 has resulted in a back-log of testing and inspections

Most bioequivalent Generic Medications may be substituted for one another without significant adverse effects
1. Generic Drug absorption is allowed to differ up to 20-25% from trade name product
2. Small differences in absorption of different Generic Medications have low clinical impact for most drugs
3. However, Exercise caution with narrow Therapeutic Index medications (Immunosuppressants, Antiepileptics)
