Parkinson's medication

Sinemet availability update


In September we informed you that some Sinemet products might be unavailable due to a manufacturing issue.

Since then we've been in regular contact with Merck Sharp & Dohme Limited (MSD), who distribute the medication, to understand the supply issues and what they're doing to ensure Sinemet is available for people with Parkinson's across the UK.

MSD have reported to us that they have been working hard to meet demand and keep all types of Sinemet that they make in stock.

They have managed to do that for the majority of the different types of Sinemet they make. However, Sinemet 25/250mg may not be in stock until the end of January 2019.

  • Sinemet 12.5/50mg 9x10 tablets, the most commonly used type, are in stock.
  • Sinemet plus 25/100mg 10x10 tablets may be unavailable from now until the middle of December, when more supplies will come into the country.
  • Sinemet plus 10/100mg 10x10 tablets may be currently unavailable, until mid-December.

As the situation changes we will post further updates.

Will this affect me?

If you're currently taking Sinemet, there is a chance that your pharmacist may be unable to give you your prescription.

There are generic versions of Co-careldopa, the active ingredient in Sinemet, available in a range of strengths. Your GP or pharmacist can discuss these with you and should be able to offer you a suitable alternative.

A statement from MSD says:

"MSD has a broad network of manufacturing facilities globally and timely delivery of our medicines to patients and providers is our key priority at all times. Unfortunately, from time to time, delays can occur for various reasons and we are doing everything we can to expedite resupplies of the presentations affected."
