What this protocol permits

Read from the signed protocol — an excerpt for reference, not advice. The medicine to be supplied is quoted verbatim (every word checked against that PDF); scope and legal category are read from it. Quantity is deliberately not reproduced here — the full protocol sets the quantity, inclusion criteria, exclusions and endorsement rules; follow the complete document issued to your pharmacy.

Where it applies: UK-wide
Legal category: POM
Medicine to be supplied: Estriol 0.01% cream
