Is compounding safe? Quality and regulation in the Netherlands

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

Medicines Act — governs the preparation of medication by pharmacies

BIG Act — requires registration of all pharmacists in the BIG register

Healthcare Quality, Complaints and Disputes Act (Wkkgz) — sets quality requirements for healthcare providers

European legislation

EU Directive 2001/83/EC, Article 3 — protects the magistral formula exemption

European Pharmacopoeia (Ph. Eur.) — sets quality standards for pharmaceutical raw materials and preparations

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:

Hygiene and workspace

Quality of raw materials

Preparation processes

Documentation and traceability

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.

How Magistra ensures quality

Magistra connects patients exclusively with pharmacies that:

Are **BIG-registered**

Are **IGJ-inspected**

Work according to **KNMP standards**

Use pharmaceutical raw materials that meet the **European Pharmacopoeia**

Magistra is a technology platform — we do not prepare medication ourselves or give medical advice. All clinical decisions are made by independent, registered healthcare professionals.

Comparison with branded products

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.
