Like many prescription drugs, Neurontin can cause a number of unwanted side effects. For instance, the effects of Neurontin on vision, memory, and balance are common side effects from taking Neurontin, along with instances of fever, nausea, and heartburn. However, it is the more serious, and potentially fatal side effects of Neurontin that have resulted in substantial amounts of litigation against Pfizer, Neurontin's manufacturer, for increased risks of suicidal tendencies in patients being treated with Neurontin. Pfizer was charged with not only failing to disclose and/or adequately warn of the risk of suicidality caused by Neurontin usage, but also for illegally and/or fraudulently marketing Neurontin to treat medical conditions other than epilepsy and shingles, the only approved uses for Neurontin. Additionally, dangerous interactions have resulted from using Neurontin in conjunction with antacids, morphine, alcohol, sleep medications, pain medications, and other seizure medications. Therefore, if you or a loved one has experienced a serious health condition as a result of taking Neurontin, you should consult an experienced products liability attorney for assistance in evaluating your case.
