Sildenafil 50 mg Tablets (Sildenafil Citrate)

Adult dose

As sildenafil, the recommended dosage is 25 to 50 mg taken orally about 1 hour before sexual activity, once daily. Depending on the situation, it can be taken from 4 hours to 30 minutes before sexual activity. Dosage may be adjusted according to efficacy and tolerance. For specific patients (aged 65 and older, liver impairment, severe kidney impairment, co-administration of CYP3A4 inhibitors, co-administration of ritonavir) the starting dose should be adjusted to 25 mg.

This medication should not be taken with nitrate drugs or NO donors, as it can cause dangerously low blood pressure in such cases. Patients taking these medications must avoid this drug. Patients with heart disease or those at high risk of cardiovascular issues should consult a doctor before using this medication to assess heart condition. Since sexual activity itself can put stress on the heart, use of this medication is not advisable for patients with poor cardiovascular health. This medication can dilate blood vessels and temporarily lower blood pressure, so caution is needed for patients with unstable blood pressure or cardiovascular diseases. Particularly patients who have experienced serious heart problems or stroke within the last 6 months, those with low blood pressure or uncontrolled high blood pressure, and those with specific eye diseases should not take this medication. If an erection lasts longer than 4 hours after taking this medication, immediate medical attention is required, as untreated prolonged erection can lead to penile tissue damage and permanent erectile dysfunction. When used with certain other medications, particularly some antivirals or antifungals, the blood concentration of this medication can significantly increase, necessitating dosage adjustment. This medication contains the artificial sweetener aspartame, so it should not be taken by patients with certain genetic disorders such as phenylketonuria. Women who are pregnant or breastfeeding should not use this medication, and it is also not recommended for children under 18 years of age. Possible side effects when taking this medication include headache, facial flushing, dyspepsia, dizziness, visual disturbances, among others, so caution is advised. When driving or operating machinery, caution is needed as this medication may cause blurred vision or dizziness. This medication should not be used with other erectile dysfunction treatments, and the safety and efficacy of concurrent use have not been established. Drug interactions should be monitored, especially if taking blood pressure medications, alpha blockers, or CYP3A4 inhibitors, and consultation with a doctor is advised prior to use. Overdose may lead to intensified side effects, so the prescribed dosage must be adhered to, and immediate consultation with healthcare personnel is necessary if unusual symptoms occur. Keep this medication out of the reach of children and do not transfer it to other containers for safety.
