Sinemet packaging to change

Sinemet packaging is changing, but the medication remains the same.

On 3 June 2021, MSD - who manufacture and distribute Parkinson's drug Sinemet - formed a new spin-off company called Organon Pharma (UK) Limited. 

Some medicines previously supplied by MSD will now be supplied by Organon, including all Sinemet products.

The company will change the packaging for Sinemet products to reflect this new company name.

However, Organon has confirmed there will be no changes to the ingredients or the look of any Sinemet tablets. 

The timing of the changes in packaging may vary between countries. You may already see that it says Organon on the packaging of your medicine if your pharmacy has imported the medicine from another country.

If you have any queries about imported (non-UK) products get in touch with the company identified on the packaging. You'll usually be able to find their details on your medicine packet.

Report any adverse reactions

If you experience any reactions to your medication please report them using the Yellow Card website. You should also report your reaction to Organon Pharma (UK) on 020 8159 3593.
