The United States Food and Drug Administration (FDA) has issued a warning that the antibiotic Zithromax has been tied to an increase risk of developing fatal heart conditions. This warning was first issued in March 2013 in response to a study linking changes in the heart's rhythm and use of Zithromax. Steps To Take If You Have Taken Zithromax People who have taken Zithromax will need to consult a drug lawsuit attorney for help. A class action lawsuit attorney is able to guide clients through the process of being included in a class action lawsuit so that they can get their fair share of damages that the drug manufacturer is ordered to pay. Being part of a class action lawsuit requires individuals to fill out paperwork and file it in a timely manner in order to stay eligible to receive a share of the award. An injury from prescription drugs lawyer will be knowledgeable about the process of filing a lawsuit against the drug company in order to recover damages for side effects of Zithromax. Family members who have lost a loved one due to complications caused by the drug should contact an attorney for help with recovering compensation for final expenses. Some family members are also entitled to compensation for loss of income if their late loved one was responsible for supporting the family. Information About Zithromax Zithromax is an antibiotic that is sold under the name azithromycin in its generic form. People who are allergic to antibiotics containing penicillin may be prescribed Zithromax to treat bacterial infections. While drug manufacturer Pfizer includes warnings about taking the antibiotic if a patient has liver problems, kidney disease or preexisting heart rhythm disorders, studies indicate the drug may actually play a key role in causing heart problems to develop. Mild side effects that have been associated with Zithromax include diarrhea, nausea, headache or dizziness. Women who take the antibiotic may experience discharge or vaginal itching. There are many drug interactions associated with Zithromax, and people who have taken the antibiotic in conjunction with blood thinners, cancer medications, antidepressants and heart rhythm medications may experience serious side effects. The Harmful Effects of Zithromax Studies reveal that taking Zithromax significantly increases a patient's chance of developing heart disorders including prolongation of the QT interval and torsades de pointes. The QT interval is a measurement that relates to the rhythm of the heart. People who have a prolongation of this interval could suffer serious complications. A heart arrhythmia could develop as a result of having a prolonged QT interval. Although it is rare for a person to die because of a prolonged QT interval, it is possible for an arrhythmia to lead to cardiac arrest and death. Torsades de pointes is another disorder that develops as a result of having a prolonged QT interval. This disorder can result in minor symptoms including dizziness, racing heart and lightheadedness. Sudden death can occur. The FDA has decided to change the labeling on Zithromax in order to inform patients about these risks. While warnings will include information about the risk of developing disorders related to the heart, the FDA has decided to inform patients to continue taking the antibiotic unless their doctor instructs them to discontinue use. It is important for anyone who has experienced complications related to the heart after taking Zithromax to contact an attorney for help. Compensation may be available for medical bills, lost wages or final expenses. Law firms with pharmaceutical lawsuit experience will be able to guide clients through the process of being included in a class action lawsuit and can advise whether this is the best course of action based on their specific situation.
