When a significant number of people are harmed by a defective product or dangerous drug, a class action suit may yield better results for the plaintiffs than individual personal injury lawsuits. An Oklahoma City class action lawyer brings a lawsuit against the defendant on behalf of several plaintiffs who have suffered, rather filing several individual claims. The benefits to a class action lawsuit include that it may be a more economical way for plaintiffs to bring suit against a negligent defendant, and the evidence demonstrating the defendant's fault is supported by multiple testimonies and stories of harmful effects. Class action lawsuits commonly include dangerous or defective medications, including diet pills. Last week, celebrity sisters Kourtney, Khloe, and Kim Kardashian were named in a $5 million class action lawsuit alleging that the Kardashians made "false, misleading, and unsubstantiated claims" in their endorsement of QuickTrim, a popular diet pill. Plaintiffs say that they bought the ineffective diet pill based on the Kardashian sisters claims that QuickTrim helped them to lose weight. Kim Kardashian claimed the diet pills helped her to lose 15 pounds and that she was taking QuickTrim to help her get in shape for her wedding to Kris Humphries--a marriage that lasted a mere 72 days. According to the lawsuit, the claims made by QuickTrim and their Kardashian spokeswomen are unfounded. According to the lawsuit, the key ingredient in QuickTrim is caffeine, an ingredient that the FDA says is neither safe nor effective for weight loss. In fact, excessive caffeine consumption can cause rapid pulse, high blood pressure, and heart arrhythmia. QuickTrim is far from the only diet pill to come under fire. Oklahoma City class action lawyers and pharmaceutical litigation attorneys have represented those harmed by prescription diet pills and over-the-counter diet supplements including Fen Phen, Meridia, Metabolife, and Hydroxycut. The most dangerous side effects of these diet drugs and supplements include elevated blood pressure, serious heart conditions, and even death. If you have been physically harmed and suffered a serious medical condition as a result of taking a dangerous diet pill, or if you have been bilked by a company making fraudulent claims about an ineffective diet pill, you may be able to bring a successful lawsuit against those responsible for your physical or financial loss. Whether you have a wrongful death claim, a fraud claim, or an injury claim against the maker or marketer of a dangerous or ineffective weight loss drug, an Oklahoma City personal injury lawyer may be able to help. During your case evaluation, the attorney may be able to determine whether your case is best litigated as a personal injury claim or a class action lawsuit.
