Cialis Side Effects Lawsuit
Viagra Side Effects Lawsuit
Popular erectile dysfunction drugs, Viagra and Cialis, can cause serious health problems. A recent survey by a renowned health website has revealed that the doctors, who were interviewed by the website, preferred prescribing Viagra to Cialis for erectile dysfunction problem because of fewer side effects. It even found many doctors asking patients not to use Cialis as the drug can cause deadly health problems, such as flu-like symptoms, hazed vision, severe lower back pain, and headache. The website notes that the continuous research has led to efforts in limiting major side effects of Viagra.
The FDA approved Viagra on 27 March 1998 and Cialis on 21 November 2003 for erectile dysfunction treatment. While Pfizer produces Viagra, Cialis is manufactured by GlaxoSmithKline. Both drugs became instantly popular, and today, more than 60 million people in the United States use these drugs. However, both reported incidents and clinical trials have shown that these drugs can cause several side effects, ranging from body pain and fever to heart stroke and permanent hearing loss.
Erectile Dysfunction Drugs Linked to Sudden Loss of Hearing
The FDA issued a warning in October 2007 linking Cialis, Levitra, and Viagra with deafness and called for revised labels on these ED drugs. This was prompted by 29 reports of sudden hearing loss caused by these drugs. The first of these reports was published in the Journal of Laryngology & Otology, April 2007 issue, stating how a 44-year-old man in India suddenly lost his hearing function after using Viagra for 15 days. It was followed by more reports and clinical trials that led the federal regulator to believe that there was a strong temporal relationship between ED drugs and sudden hearing loss in patients.
British Study: ED Drugs Cause NAION or Eye Stroke
The British Journal of Ophthalmology reported in 2006 that using Viagra put people with high blood pressure or heart attack at higher risk of non-arteritic anterior ischemic optic neuropathy (NAION), commonly called stroke of the eye. A study by Birmingham’s University of Alabama confirmed NAION in patients within three days of using Viagra.
Research by the Public Citizen Health Research Group, a consumer advocacy group, claims that men using ED drugs are at a greater risk of developing NAION. While those taking Viagra are 18 times more prone to it, using Cialis makes them 25 times more vulnerable.
FDA: ED Drugs Cause Vision Loss
The FDA received 43 reports of vision loss caused by use of ED drugs between 1998 and 2004. The victims were found to be using Viagra in 38 cases, while the rest used Cialis and Levitra. The manufacturers of the three ED drugs were asked to issue warnings to this effect.
Side Effects Proved in Clinical Trials
Various reports and clinical trials found the following side effects of Cialis and Viagra, the two most popular ED drugs.
Cialis Side Effects
GlaxoSmithKline's Cialis is commonly known as the weekend pill. It has PDE5 inhibitor tadafil, which maintains longer duration of erection during sexual stimulation. The list of its side effects is equally long. Most men using Cialis experience headache, muscle aches, indigestion, back pain, and stuffy or running nose. These side effects appear as result of tadafil’s vasodilate quality that widens blood vessels. Back ache and muscle pain persist even 24 to 48 hours after consumption of the drug.
Many using this drug complain of dizziness, heartburn, and stomach upset. Sometimes severe allergic reactions caused by the drug can be fatal. Fainting, painful erection, seizures, and vision changes are also associated with men using Cialis. The clinical studies have shown that the drug can lead to the following major health problems.
Cialis causes hypersensitivity reactions in human body, such as urticaria, dermatitis, Stevens-Johnson syndrome, asthenia, and pain.
Cardiovascular problems caused by the drug can be more serious. Angina pectoris, hypotension, chest pain, sudden cardiac arrest, myocardial infarction, and stroke are associated with tadafil use. Many of these problems occur with or without sexual activity.
Digestive health issue associated with Cialis are abnormal liver function, GGTP increased, dry mouth, loose stools, upper abdominal pain, and vomiting.
