Breaking News: Update on Sinemet Shortage

Release date: 3/9/2011

Update: You can view images of the new tablets here.

Merck has sent a letter to the Parkinson's community to inform us that the FDA has approved their new supplier of Sinemet and Sinemet CR. Merck believes that this should mark the end of the Sinemet shortage. As a result of this change, the pills you receive from the pharmacy will likely be changing in shape, color, and marking. The tablets will no longer be scored for splitting. NPF will post images of the new pills to our website as soon as they become available.

Though we think the shortage is coming to an end, NPF has received calls in the past 24 hours from people who were unable to fill a prescription for Sinemet. We have information that there may be trouble filling prescriptions for Sinemet immediate release 25/250 and Sinemet CR in the 25/100 and 50/200 formulations. NPF has been collecting reports from people unable to fill a prescription for branded Sinemet as well as from people who have experienced negative effects from being switched to a generic version of their medication. We hope to prepare a letter to Merck and the FDA detailing the current situation and its impact on patients.

If you have been affected by the Sinemet shortage either because you have been unable to fill your Sinemet prescription or if you have experienced challenges after switching to a generic alternative, NPF would like to know. Please call us at 1-800-4PD-INFO (1-800-473-4636) and tell us about your situation.
