Thanks for going further and contacting the FDA. I thought it odd that the three countries receiving official notice of the shortage all have ties to the British crown. Probably no there, there, but odd nonetheless. I also ran across a study singling out the NHS in the UK as a culprit in the shortage that is underway there. It seems there is a medicine supply chain problem there. Sinemet is not the only drug in short supply.

How this expands to Canada and Australia beyond the crown connection, I'm not sure, unless they are linked via production and supply?

Lindy can you make sense of this?
