This medication is used as a treatment for erectile dysfunction and can exert strain on the heart during sexual activity, so a thorough cardiovascular evaluation by a physician is necessary before starting treatment. It is generally not used in patients with heart or vascular problems. Particularly, patients with significant left ventricular outflow obstruction or severely impaired blood pressure control may be more sensitive to the vascular dilatory effects of this medication and should exercise caution. If an erection lasts longer than 4 hours, immediate medical assistance should be sought as untreated priapism can lead to penile tissue damage or impotence. Patients taking nitrate compounds or nitric oxide donors concurrently with this medication may experience dangerously low blood pressure, therefore, it is essential to inform the physician and avoid combination. Patients with allergies to this medication or its excipients, serious cardiovascular diseases, a history of stroke or myocardial infarction within the last 6 months, uncontrolled hypertension or hypotension, hereditary retinal disorders, severe liver or kidney dysfunction, those taking specific antiviral agents, children under 18 years of age, and patients with lactose intolerance should not use this medication. Patients with anatomical penile deformation, hematologic diseases, or diminished liver or kidney function should use this medication cautiously, as well as those taking certain antifungals, antibiotics, or alpha-blockers. Common side effects of this medication include facial flushing, headaches, eye redness, dyspepsia, and less commonly dizziness, blurred vision, skin rashes, and nausea. This medication impacts the heart and blood vessels, so cardiovascular status must be evaluated before sexual activity, and it should be used restrictively only in patients who clinically require treatment for erectile dysfunction. Caution should be exercised as dizziness or blurred vision may occur when driving or operating machinery. It should not be used by pregnant or breastfeeding women, and dosage adjustments are not necessary for the elderly.
