It is suggested not to take Viagra if you are already taking nitrates that are prescribed for chest pain. Taking Viagra with nitrates can cause a sudden and unsafe fall in your blood pressure. Consult your doctor and give him your complete health status so that it is ensured that you can safely indulge in sexual activities. You should seek immediate medical help if during sex you feel sudden chest pain or nausea or any other such discomfort.
If after taking Viagra your erection lasts for more than four hours, immediately consult your doctor so that long term injury can be avoided. A person who is more than 65 years of age and has serious kidney or liver problems will be given the lowest dose i.e. 25 mg of Viagra as the introductory treatment. If protease inhibitors are also being taken for treatment of diseases like HIV, the doctor will generally recommend a dose of 25 mg and will limit you to that dose which should be taken at a difference of 48 hours.
In some rare cases, people taking PDE5 inhibitors as well as Viagra to get rid of erectile dysfunction have reported a decrease on vision.

However it is recommended to stop taking these drugs as soon as you discover this loss in hearing and consult your medical practitioner immediately.
The doctor will introduce a patient with a lower dose of Viagra if that patient is suffering with high blood pressure or prostate problems and is under the treatment of medicines like alpha blockers.
