FDA has received reports of cases of sudden decreases or loss of hearing following the use of PDE5 inhibitors, Viagra, Levitra, and Cialis for the treatment of erectile dysfunction and Revatio for the treatment of pulmonary arterial hypertension. In some cases, the sudden hearing loss was accompanied by tinnitus and dizziness. Medical follow-up information was often limited for the cases reported postmarketing, which makes it difficult to determine whether these reports are directly related to the use of one of these drugs, an underlying medical condition, or other risk factors for hearing loss, a combination of these factors, or other factors. Sudden hearing loss was also reported in a few patients in clinical trials of these drugs. In response to a request from FDA, the manufacturers of Viagra, Levitra and Cialis have revised the labeling for these products to address the potential risk of sudden hearing loss and to guide patients on what to do if they experience sudden problems with their hearing. FDA is currently working with the sponsor to revise the labeling for Revatio. The approved revised labeling for Viagra, Levitra and Cialis includes a new sections. The revised labeling is available at . This information reflects FDA’s current analysis of data available to FDA concerning this drug. FDA intends to update this sheet when additional information or analyses become available. Includes previous safety information and approval packages. foreign generic viagra Erectile dysfunction in men is a common problem, even more so in men over the age of 45. different lifestyle traits can contribute to erectile dysfunction, however Viagra is the most commonly used cure for impotence and erectile dysfunction. It is not necessarily the case that men naturally experience a lower sexual drive or erectile dysfunction when they reach a certain age. A man's inability to gain and sustain an erection may be due more to abnormalities in treatable physical conditions. In 1983, Dr Giles Brindley made the discovery and demonstrated that a penis could be made erect by injecting it with the drug Phentolamine. He discovered the penis could be mad erect by relaxing the normally constricted blood vessels. Once the vessels are relaxed, they let increased blood into the penis, which then inflates to form an erection. Two problems however were soon recognised. Phentolamine is not selective enough to target only the penis to inflate and can unpredictably effect other parts of the body. Secondly, the erection is not brought on by sexual stimulation and a man will continue to have an erection until the drug wears off. Viagra combats such drawbacks however. It works by enhancing the natural process that occurs when a man is sexually stimulated. Viagra controls what we might call â€?softeners'- chemicals in the body designed to make the penis soften after an erection has occurred. When a man is sexually stimulated chemicals in the body relax the blood vessels in his penis and increase the blood flow. At the same time the body also produces phosphodiesterase (PDE5), which work to subside the erection afterwards. Erectile dysfunction is an imbalance which results in the inability of a male to sustain an erection. Viagra reduced such â€?softeners', allowing blood flow to the penis to create sustainable erections. Viagra does not take the place of stimulation but increases the effects of stimulation. After the Viagra has worn off (usually 4 or 5 hours later), the normal processes are restored to how they were prior to taking Viagra. Possible side effects can occur, such as flushing and dizziness, and if an individual experiences these, they should consult a doctor. When we speak of sex drive problems, or dysfunction, we automatically think of males and erectile dysfunction, and omit women from the equation. However, many women experience problems with their â€?libido' or sexual energy, and this phenomena deserves attention too. Viagra is the most common treatment for erectile dysfunction in males, and has traditionally been recommended for men only, women being advised not to use it. So the main reason for this is lack of empirical research stating otherwise, which is due to the absence of definitive studies on women. Viagra however can work for women, as it increases the blood flow to a woman's genitals (much the same way as with a man's), which boosts their libido. There are important considerations however, which shall be listed below. As Viagra is aimed at men's erectile dysfunction, women are unable to obtain a prescription and buy Viagra from a pharmaceutical store. However generic versions are available on the internet, but as so many are on the market, if in doubt contact the supplier as to whether a product is available. When buying from online pharmacies, it is possible to check their pharmacy ID if concerned about legitimacy. It is important for women to take into consideration possible side effects of Viagra, although not widespread there is still a possibility of them occurring. For instance, some Viagra users have reported dizziness, flushing, loss of vision, and so on. Check all possible side effects before commencing use. Furthermore, Viagra should not be taken alongside any nitrate medicines as this can cause abnormally low blood pressure, so always check! Women, who suffer with a low sex drive often, should seek a long term cure other then Viagra in order to increase their libido and have a permanent effect. Long term Viagra use can result in expense, so if the problem continues regularly, even after Viagra use, women should aim to seek other remedial methods.
