Cialis 40mg is a drug that is generally prescribed for the treatment of erectile dysfunction and the alleviation of symptoms associated with benign prostatic hyperplasia. Tadalafil is the active agent in Cialis, and its action consists in facilitating an erection by boosting blood flow to the penis during sexual stimulation. This feature of the drug together with its high efficacy makes it a popular option among men because one can have sex during its effective period of 36 hours without worrying about the timing. It is always advisable for patients to get the opinion of a doctor regarding the right dosage and to inform him/her about any other drugs they are taking and their health status.

Apart from being the mainstay treatment for erectile dysfunction, Cialis has also been used for the management of pulmonary arterial hypertension, which is a disorder marked by high blood pressure in the pulmonary artery system, the vessels leading to and from the lungs. The action of the drug in this case is through the smoothness of the blood vessels, which not only enhances exercise capacity but also improves the patients’ overall quality of life who are afflicted with the disease. Like every other medicine, it is very important for the patients to strictly follow the prescribed dosage and to be conscious of the side effects that might occur such as headaches, nausea, and muscle pain. Consequently, scheduling periodic appointments with a healthcare provider is advised for the assessment of treatment efficacy and modification if needed.
