Happygra Tablet 50 mg (Sildenafil Citrate)

Adult dose

As sildenafil, take the recommended dose of 25 – 50 mg orally about 1 hour before sexual activity once a day. In some cases, it can be taken between 4 hours to 30 minutes before sexual activity. The dosage may be adjusted based on efficacy and tolerability.

This drug acts by dilating blood vessels, which can lower blood pressure, so there is a risk of excessively low blood pressure if taken with nitrate preparations or nitric oxide donors. Patients with cardiovascular disease should confirm their heart condition before using this drug and should not use it if they have unstable cardiovascular status. This medication is for erectile dysfunction treatment and is not to be used by children under 18 or women. Elderly patients or those with impaired liver or kidney function may have increased blood levels of this drug, so they should start with a lower dose. If an erection lasts more than 4 hours while taking this drug, immediate medical attention is required, as untreated cases can lead to penile tissue damage and permanent erectile dysfunction. This drug can cause side effects such as visual abnormalities, headache, flushing, dyspepsia, and dizziness, so caution is needed if such symptoms arise. This drug may interact with certain medications, particularly those that are CYP3A4 inhibitors or drugs like ritonavir, which may require dosage adjustments. If sudden vision loss or hearing reduction occurs while taking this drug, stop immediately and consult a healthcare provider. Taking the drug with food may delay the onset of effects, so the meal status should be considered when taking it. This drug should not be used for purposes other than treating erectile dysfunction, and it does not provide any protection against sexually transmitted diseases. Caution is warranted when driving or operating machinery due to the possibility of dizziness or visual abnormalities. When taken with alpha-blockers, symptoms of low blood pressure may appear, so intervals between doses should be maintained. This drug should never be used in conjunction with nitrate preparations, either regularly or intermittently, and patients with a history of severe cardiovascular diseases like recent myocardial infarction or stroke should also not use this drug. It is essential to consult with a doctor before taking this medication to accurately report one’s health condition and any medications currently being taken.
