Shortage information
Natpar is used to treat adults with hypoparathyroidism (under-active parathyroid glands). It is used as an add-on to treatment with calcium and vitamin D supplements when these treatments have not worked well enough.
Manufacturing of all strengths of Natpar will be discontinued globally at the end of 2024 and as a result Natpar will be withdrawn from the global market. This is due to manufacturing challenges which already affected the Natpar 100 micrograms/dose strength which has been unavailable since the end of June 2022. Beyond 2024, Takeda intends to supply available doses until the inventory is depleted or expired.
All EU/EEA Member States where Natpar is marketed: Austria, Belgium*, Cyprus*, Czech Republic, Finland, Germany, Greece, Hungary, Italy*, the Netherlands, Portugal*, Romania*, Spain*, Sweden and Norway.
The countries marked with an * indicate countries with a named patient program.

- a reduced dose of 75 micrograms once a day, if appropriate.
- For any alternative regimen, patients should be given instructions on how to give the injection (please refer to appendix of the direct healthcare professional communication (DHPC)).
