Topiramate Tablets are the generic version of Ortho-McNeil's Topamax® Tablets, which had U.S. sales of approximately $1.37 billion for the three strengths approved for the 12-month period ended June 30, 2006, according to IMS Health. Mylan also received tentative approval for the 50mg strength of Topiramate.

The FDA has confirmed that Mylan was the first generic company to file on the 25mg, 100mg and 200mg strengths of Topiramate and is therefore eligible for 180 days of market exclusivity.
