Viagra (sildenafil citrate) is the most recognized brand of medicine used for the treatment of male impotence, or erectile dysfunction. Viagra comes in tablets intended for oral administration and is available in three doses – 25 mg, 50 mg and 100 mg. If you happened to skip a dose of this medicine you don’t have to make up for it as people taking Viagra are recommended to take it only when needed, but not more often than every 24 hours. Some patients whose health condition, age or other factors cause concern may be recommended to take Viagra even less often to make sure the treatment does not cause harm to their health and well-being. It’s important that your health care provider is informed about any of the health conditions you have ever been diagnosed with. This allows prescribing the exact dosage you need to help you perform sexually at the same time not leading to serious or bothersome side effects.
The following health conditions should be mentioned when you are examined by your health care provider: pulmonary veno-occlusive disease, irregular heartbeat, bleeding disorder, multiple myeloma, diabetes, high cholesterol, chest pain, heart attack, blood circulation problems, blood cell problems, kidney or liver disease, and leukemia. People who were asked by their doctor to refrain from sexual activity due to health reasons should follow the guidelines of their health care professional as otherwise they can experience dangerous symptoms and will have to seek emergency medical assistance.
