Supply issue: 20 mg tablets

Stocks of Nyefax Retard brand nifedipine 20 mg (pharmacode: 529435) are running low. This is due to a manufacturing issue. The supplier (Douglas) anticipates the registered product to be available again by the end of the year.

We are listing an alternative brand from 1 May 2021.

  • Brand: Mylan nifedipine
  • Presentation: 20 mg
  • Listed: 1 May 2021
  • Available: We are advised stock will be available in late April.
  • Pharmacode: TBC

The Mylan product is not Medsafe approved. It will need to be supplied in line with section 29 of the Medicines Act. 

Discontinuation of Adalat brand 10, 30, 60 mg tablets

As communicated in January 2021, the supplier of the Adalat brand of nifedipine tab long acting 10mg, 30 mg and 60 mg has discontinued the Adalat brand. The stock was exhausted in January 2021. It will be delisted on 1 August 2021.

Alternative brands of nifedipine, Tensipine MR 10 and Mylan nifedipine have been sourced and supplied since January 2021.

The Mylan and Tensipine brands are not registered in New Zealand. They must be supplied in line with section 29 of the Medicines Act 1981. 

We know supplying a medicine under section 29 is not ideal because only medical practitioners can prescribe it. Section 29 supply was the only option. Using these unapproved brands ensures patients can continue to access funded nifedipine.

Read the Medsafe website for more information about your obligations under section 29.
