Salbutamol with ipratropium bromide (Duolin) nebuliser: Supply issue

Supply issue Active

A manufacturing delay will cause a supply constraint for Duolin salbutamol with ipratropium nebuliser solution (Pharmacode 2039281).

Affected product

Rex Medical, the supplier, advises that the manufacturing site for Duolin nebuliser solution has temporarily halted production to facilitate annual validation. Rex Medical has moved production of this medicine to a second registered site. This has caused a delay in resupply.

Rex Medical has advised that they have enough stock to supply the market until approximately mid-September.

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. The medicine must be prescribed by someone registered with the Medical Council of New Zealand – such as, a doctor. 

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.
