BusinessWeek -- Drugs used to treat epileptic seizures can raise suicide risks, but not enough to warrant the strongest warning labels available, a government panel of experts said Thursday. Advisers to the Food and Drug Administration voted 14-4 against adding a “black box” warning about the risks of suicidal tendencies to all anti-seizure drugs. The experts said they worried the warning labels could inadvertently cause doctors and patients to abandon the treatments.
