This seemingly benign medication can have a deadly result.  Cardiac collapse, seizures and bronchospasm are serious side effects of Benzoatate overdose.  I have listed several references from different sites for your reference.  If you know of someone who takes Tessalon Perles, please make sure they do not chew or bite them.  I cannot say that this is what happened to Lisa, but I cannot think of anything short of an asthma attack that would have killed  her.  Stay informed about your medications!  If you take prescription medications, always carry a list with you that includes the medication, the dose in mg and the frequency.
