MSD has informed the Health Products Regulatory Authority (HPRA) we are anticipating a stock shortage of some SINEMET® products, a product used by patients for the treatment of Parkinson’s Disease, in the Irish market in the coming months due to global manufacturing delays in production and resupply of these products.

The following products are out of stock and will be resupplied in Q1 2019 (by the end of March 2019).

SINEMET 25/250MG 10X10 Tablets

SINEMET PLUS 25/100MG 10X10 Tablets

MSD would like to assure you that we are working to resolve this situation as soon as reasonably possible and anticipate these products will be resupplied in Q1 2019 (by the end of March 2019).

We recommend that any prescription for carbidopa/levodopa is written generically as supplies of alternative carbidopa-levodopa may be available from wholesalers. The Health Products Regulatory Authority (HPRA) has advised MSD that this alternative carbidopa/levodopa supply will be through the exempt medicines (unlicensed medicines) scheme.
