Washington - The Pfizer company, which makes the Viagra drug to cure male impotence, has defended its safety following the deaths in the US of six users of the pill, writes Joe Carroll. But a 61-year-old New York woman, Ms Roberta Bernardo, is suing her 70-year-old common law husband for $2 million claiming that the drug has led to her partner's infidelity. The woman's lawyer said she may also sue Pfizer for negligence, saying the company should warn that the drug could be hazardous to marriages and offer emotional counselling with the diamond-shaped blue pills.
Pfizer in a statement says it has reviewed the circumstances of the deaths of the six men and decided not to make any changes in the labelling of the drug, which warns against mixing Viagra with certain heart medications. The label was approved by the US Food and Drug Administration before Viagra was put on sale.
