Any drug manufacturer has the responsibility to make its drugs as safe as reasonably possible, although unanticipated side effects of any drug are always a potential danger. However, the manufacturer has a duty under the law to advise the public, as well as medical professionals, of the risks and dangers of taking a particular medication. If a manufacturer fails to adequately warn consumers and the medical community of the known risks of a drug, then it may be liable under products liability law. For instance, a Neurontin prescription for patients suffering from epilepsy and shingles, in some cases, has resulted in a substantially increased risk of suicidal behaviors and thoughts, which has given rise to a number of lawsuits alleging liability on behalf of Neurontin's manufacturer for failure to warn of these potentially fatal side effects. Ultimately, Pfizer, the manufacturer of Neurontin, has paid out more than $430 million in settlements for its actions in causing consumers to become injured by the use of Neurontin.
