The maker of the antidepressant Paxil has been hit with five new lawsuits claiming the drug caused heart defects with serious health consequences, including the death of a West Virginia toddler.

Baum Hedlund, a Los Angeles-based law firm specializing in pharmaceutical product liability claims, has filed five lawsuits in Pennsylvania state court charging that use of the drug by pregnant women led to heart defects in their children. The suits also allege that the birth defects led to the deaths of three children and have seriously impaired the health of two others.
