According to the research, Viagra’s effectiveness in treating erectile dysfunction, as a result of sexual stimulation, can lead to a number of side effects. These include headaches, flushing, indigestion, upset stomach, back pain, muscle aches, pain, rash, and vision changes. These side effects are common in people with mild to moderate forms of erectile dysfunction, such as low-grade prostatic hyperplasia (Lgu-PDE5), which is caused by a combination of factors, including age, smoking, and drinking.

TUESDAY, Oct. 6 / -- Pfizer Inc. said Friday it will pay $8.4 billion to settle a class-action lawsuit brought by some patients who allege that the drug maker hid the risks of the blockbuster erectile dysfunction drug Viagra.
The lawsuit, which names Pfizer Inc., alleged that Pfizer illegally marketed its blockbuster drug in violation of the Federal Food, Drug and Cosmetic Act.
The complaint, which was filed Friday in federal district court in Indianapolis, alleges that the company "directly and knowingly received false and misleading information" about the efficacy of Viagra, which Pfizer was selling at $4.4 billion in the United States.
The complaint also alleges that Pfizer knew of the risks associated with the drug's use and that the drug "has not been approved by the FDA, has not been approved by the Food and Drug Administration and is not intended for human use."
The lawsuit was filed by several lawsuits filed by men who claim that Pfizer violated various federal and state laws regarding the marketing of impotence drugs.
The complaint alleges that Pfizer's patent on the drug contained no "undisclosed patent rights" and that the patent is valid until the FDA approves a new drug.
Pfizer's lawsuit also alleges that the company illegally marketed Viagra to treat impotence and to market the drug as a treatment for erectile dysfunction.
"Pfizer is deliberately misleading physicians, physicians, patients and consumers about the risks and benefits of Viagra and its potential side effects," said Mark C. McKinnell, Pfizer's chairman and CEO. "The company has failed to adequately disclose to patients, patients and physicians the substantial side effects of Viagra and the serious risks associated with this product."
The lawsuit is part of the largest class-action lawsuit since it was launched in 1993, brought by hundreds of plaintiffs. The suit alleges that Pfizer improperly marketed and promoted Viagra to patients and doctors who were not adequately informed of the risks, and illegally marketed the drug to consumers, doctors and other health care providers.
Pfizer Inc. is a U. S. company that is one of the largest pharmaceutical companies in the world. In 2009, it earned $12.9 billion. It was among the top three companies in the world for revenue in 2010, according to IQVIA data. The world's top pharmaceutical company was named in the most recent report by Medscape.com.
The lawsuit alleges that Pfizer engaged in unfair trade practices by encouraging its drug and misleading doctors and patients about its efficacy and side effects.
Pfizer is a global leader in the research and development of new drugs. It has a deep clinical reach and a growing research and development pipeline, with more than 1,400 drugs expected to be launched in the next three years. In 2010, it earned $6.2 billion.
As of this writing, the class-action lawsuit is still pending in state court.
