Q. Does Viagra have any side effects?
My boyfriend started taking Viagra and now he has headaches. Could this be caused by the Viagra?

Q. What are the risks of taking Viagra?
Are there any risks in taking Viagra in the long term?
|A1||The US Food and Drug Administration identified 50 men with blindness who have taken Viagra, but who also had diabetes and heart disease, which is known to cause blindness. Therefore, it is not certain if it was caused directly from the Viagra.|
The FDA informed healthcare professionals in October, 2007 that drugs used to treat erectile dysfunction, including Viagra, may increase risk of sudden hearing loss.
|A2||Viagra's prescribing instructions warn against use by men taking heart drugs known as nitrates and caution about sudden vision and hearing loss and other problems.|
|A3||Although few serious side effects have been seen, recent reports (2005) suggest a possible risk of blindness from non-arteritic ischaemic optic neuropathy. This is a rare condition in which blood supply is reduced to the optic nerve causing permanent nerve damage.|
Q. Does Viagra increase the chance of getting HIV?
I heard that taking Viagra can increase the chances of getting HIV when having sexual contact. Is this true?
|A1||There is no proof that Viagra increases the risk to catch HIV. However there have been studies made, which show that men who use Viagra behave differently by having multiple sexual partners and/ or having unprotected sex, which both increase the chances of getting infected with HIV.|
|A2||Viagra does not increase the chances of getting HIV. However it is not a substitute for condoms and other STD (sexually transmitted disease) prevention methods.|
