We are very sorry to tell you that Takeda have just informed us of shortages of the 100mcg dose of Natpar from late June/early July due to a manufacturer supply issue. This will affect UK, Europe and Canada. They expect to get this fixed within 6 months. The 75mcg dose will also be affected from September. The 50mcg and 25mcg doses are not affected. Endocrinologists will be informed by letter this week so please contact your doctor to discuss future plans and place orders now. We will keep you informed of any further updates.
