Prescribing and supplying an unapproved medicine

Section 29 of the Medicines Act 1981 allows for medicines that are not Medsafe approved to be prescribed and supplied to people. 

We know supplying a medicine under section 29 is not ideal. In this case, however, this will allow patients to be able to access an appropriate treatment. 

We apologise for any inconvenience this causes.
