Is compounding safe? Quality and regulation in the Netherlands
How safe are compounded preparations? An overview of Dutch and European regulation, quality controls and registration requirements for compounding pharmacies.
The safety of compounded preparations
An understandable question: if a pharmacy custom-makes medication, how do you know it's safe? The answer lies in the strict Dutch and European regulations surrounding this practice.
Legal framework
Compounding is regulated by multiple legal frameworks:
Dutch legislation
European legislation
Quality controls
Every compounding pharmacy in the Netherlands must meet strict quality requirements:
BIG registration
Every pharmacist who prepares compounded medications must be registered in the BIG register (Healthcare Professionals Register). This register is public and verifiable.
IGJ inspection
The Health and Youth Care Inspectorate (IGJ) regularly inspects compounding pharmacies on:
KNMP guidelines
The Royal Dutch Pharmacists Association (KNMP) publishes guidelines for compounding that pharmacies must follow.
European Pharmacopoeia
All pharmaceutical raw materials (APIs) must meet European Pharmacopoeia standards — the same standards that apply to the production of branded products.
What to check before choosing a pharmacy

Comparison with branded products
| Aspect | Branded products | Compounding |
|---|---|---|
| Production | Pharmaceutical factory | Licensed pharmacy |
| Quality standard | GMP (Good Manufacturing Practice) | European Pharmacopoeia |
| Oversight | CBG/EMA | IGJ |
| Registration | Marketing authorisation | BIG register |
| Raw materials | Pharmaceutical | Pharmaceutical |
| Traceability | Batch number | Individual preparation report |
Both systems ensure the quality and safety of the medication. The difference lies in the scale (mass vs. individual) and the degree of personalisation.
Conclusion
Compounding is a safe, legally protected practice with robust oversight by Dutch and European authorities. Every preparation is made by a qualified, registered pharmacist under supervision of the IGJ.
