A new study suggests that the most common side effects of Viagra are caused by the side effects of the drug itself.
The Food and Drug Administration on Friday said the drug's side effects are largely due to the way the drug works, and not the way Viagra is designed to work. The agency also warned that "a drug like Viagra is not effective in treating erectile dysfunction."
Viagra, the same class of drugs as Cialis, is the first of its kind to be approved for the treatment of erectile dysfunction in men. However, it is not yet widely available in the U. S. and there is little evidence that it is effective in the U. and in many other countries. And the Food and Drug Administration is not yet able to determine if Viagra can be safely used for the treatment of ED.
In its new findings, the agency said, Viagra may be able to help treat symptoms of benign prostatic hyperplasia (BPH) in some patients. According to a study by the National Institutes of Health, a small group of patients with BPH who used Viagra reported symptoms such as a "chronic, frequent, or recurrent erection problems."
The FDA does not know whether Viagra is safe for use in women.
The study, from, will be conducted in the U. The FDA, in a statement, said the study is designed to test the safety of Viagra.
The drug is not yet the first treatment to be approved for men with BPH, or erectile dysfunction in men.
Viagra was first introduced in 1998 in the United States as an oral medication for treating the symptoms of enlarged prostate. It is the only drug approved by the FDA to treat the condition that causes difficulty urinating.
Researchers have conducted several more studies to determine whether Viagra can treat the symptoms of BPH and to determine whether Viagra has the same effect on men with ED.
The agency also said that Viagra should not be used by people who have not had an erection within the last month. In other cases, the drug may be used to treat symptoms of BPH in men.
In a, the agency said it is not aware of studies in the U. and other countries that have shown Viagra may be effective in treating BPH.
In March, a study published in the journal Urology also showed that the FDA found that men taking Viagra were twice as likely to develop ED than men taking a placebo.
In June, researchers at the University of North Carolina School of Medicine found that Viagra reduced the risk of developing a heart attack or stroke in men who took the drug. Viagra, the same drug as Cialis, is the only approved drug for the treatment of erectile dysfunction. It is not yet available in the U.
In August, the FDA issued a warning about the possible effects of Viagra on men taking nitroglycerin. It was also told that Viagra, a drug used to treat angina and heart attacks, may be linked to a small increased risk of stroke.
Viagra and Cialis are both approved to treat erectile dysfunction, but they may be used in combination. Viagra may also be used to treat benign prostatic hyperplasia, or BPH.
In the U. S., the FDA has not been able to determine whether the drug can be used safely for the treatment of ED in women.
