FOR IMMEDIATE RELEASE:

The Medicines Company Announces Preliminary Worldwide Net Revenue for the First Quarter of 2015

Parsippany, NJ, April 09, 2015- The Medicines Company (NASDAQ: MDCO) today announced preliminary worldwide net revenue for the first quarter of 2015.

The Company expects worldwide net revenue in the range of $125 million to $130 million for the first quarter of 2015, which reflects a 29% to 26% decrease from the $177.2 million in worldwide net revenue reported for the first quarter of 2014. The decrease in worldwide net revenue is a result of lower worldwide net revenue from sales of Angiomax^® (bivalirudin)/Angiox^® (bivalirudin), which the Company expects to be in the range of $97 million to $105 million compared to $155.7 million in the first quarter of 2014.

”We believe the decline in first-quarter worldwide net revenue from sales of Angiomax reflects our customers’ current uncertainty regarding the product’s patent exclusivity in the United States past June 2015,” said Clive Meanwell, MD, PhD, Chairman and CEO of The Medicines Company. “We appreciate our customers’ concerns about managing their pharmaceutical inventories. At the same time, we are pleased to see growth in our other products year-on-year and we expect this to continue as we diversify our sources of revenue. We will continue to provide our hospital customers with the high level of product support they have come to expect from us for all of our brands.”

Final financial results for the first quarter are not yet available. The financial estimates presented are preliminary and are subject to change. Actual results for the quarter may differ materially from the
