This is Perrigo's second recent expansion:
The expansion will boost manufacturing capacity by at least 10 percent, Perrigo Chief Executive Officer Joseph Papa said.
The company currently has 1.8 million square feet of manufacturing and office space in seven Allegan area facilities.
"Right now, the market demand for health care pharmaceutical products is up 3 percent, while store branded product sales are up 16.8 percent and our sales are up 40 percent," Papa said.
In September, the company announced the $44 million purchase of JB Laboratories in Holland that added $70 million in annual sales and 160,000 square feet of manufacturing space.
