WASHINGTON - Hundreds of patients taking Pfizer's anti-smoking drug Chantix have reported serious accidents, vision problems and heart trouble, researchers said.
Researchers at the nonprofit Institute for Safe Medication Practices and at Wake Forest University said they found hundreds of reported problems since the drug's 2006 approval. They included blurred vision, dizziness, confusion and loss of consciousness.
Pfizer officials defended Chantix, saying the side effects are mentioned on the drug's label. "When you've got the nicotine withdrawal along with Chantix, it's just very difficult to tell what is causing it," said Gretchen Dieck, a Pfizer senior vice president.
