JERUSALEM Teva Pharmaceutical Industries has launched a generic oral contraceptive, the drug maker said Tuesday.

Gianvi is the generic version of Bayer's Yaz tablets, which had total sales of nearly $782 million in the United States for 12 months ended Dec. 31. Teva has been awarded a 180-day period of marketing exclusivity for the contraceptive.

As previously announced, Teva has the right to launch an authorized generic version of the product, supplied by Bayer, in July 2011.
