This product is/was manufactured by Monticello Drug Company. This company is still in business. I did not, however, find this product listed among their currently available products at: http://www.monticellodrug.com/mdc-products.html. I suppose if your really interested you could contact the company to find why this product is no longer listed on their website as a product they produce. It is possible that this product may still be available in other markets, other than the U.S.; the manufacturer could direct you where this may be.
The phone number for this company is: 1-800-735-0666 Ext. 126.
