Getting it in the UK

Getting it in the UKPrescribable, but not approved for this

Still legal for a doctor to prescribe, but it hasn't been officially approved for this specific use. Uncommon, and comes down to a specialist's own judgement.

MHRA: the UK government body that checks a medicine is safe and actually works before doctors are allowed to prescribe it.
