Canada issues warning about Viagra vision loss

Tue Jul 26, 2005 5:53 PM BST

OTTAWA (Reuters) - Canada advised users of the erectile dysfunction drugs Viagra, Cialis and Levitra on Tuesday to "seek immediate medical attention" if they experience sudden vision loss or other vision-related problems when taking the medications.

Canada's health ministry said it was likely to change the product information for the three drugs. Earlier this month the U.S. Food and Drug Administration approved new labeling to warn men about possible blindness from Pfizer Inc.'s Viagra.

The U.S. warning labels also affect Cialis -- sold by Eli Lily & Co. and Icos Corp. -- and Levitra, which is co-promoted by GlaxoSmithKline and Bayer AG .
