This medication acts as a vasodilator and may lower blood pressure, so it should not be used in patients who are taking nitrates or NO donors. Patients with cardiovascular disease should confirm their cardiac condition before using this medication, as sexual activity itself can place a strain on the heart. This medication may temporarily lower blood pressure, so caution is required for patients who are hypotensive or hypertensive. If an erection lasts longer than 4 hours, seek medical attention immediately, as untreated cases can lead to permanent damage. Patients with certain heart conditions or reduced blood pressure control may be more sensitive to this medication, so caution is advised. Taking this medication together with certain drugs like Ritonavir can significantly increase its blood concentration, necessitating dosage adjustments. Patients allergic to this medication or its components, those regularly taking nitrates, those with severe cardiovascular conditions, severely impaired liver or kidney function, children under 18 years, and women should not take this medication. Patients with penile deformities, bleeding disorders, the elderly, and those with diabetic retinopathy should use this medication cautiously, with elderly or liver/kidney failure patients advised to start at lower doses. Common side effects when taking this medication include headaches, flushing, dyspepsia, dizziness, visual disturbances, etc.; if symptoms are severe, consult a doctor. Serious side effects like cardiovascular adverse reactions, sudden loss of vision, and hearing loss have been reported infrequently; report any abnormal symptoms to medical personnel immediately. Caution is needed when driving or operating machinery, as visual disturbances or dizziness may occur. The risk of side effects may increase when taken with other erectile dysfunction medications or certain antihypertensive agents, so consult with a physician.
