Suhagra 25 mg (sildenafil) should read its precautions, especially people with heart conditions, low blood pressure, or those taking other medicines. Who should be especially careful? People with heart disease: Especially those with unstable chest pain, serious heart problems, or who have recently had a heart attack or stroke. People taking nitrate medicines: Such as nitroglycerin or isosorbide for chest pain. Combining these with sildenafil can cause a dangerous drop in blood pressure. People with low blood pressure: Sildenafil may lower blood pressure further. People with liver or kidney problems: They may need a lower dose or extra medical supervision. People taking certain medicines: Some blood-pressure medicines, alpha-blockers (such as doxazosin), and certain antibiotics or antifungal medicines can interact with sildenafil. People with certain eye conditions: Anyone with a history of sudden vision loss should consult a doctor before use. People with penile deformities or a history of prolonged erections: They should discuss the risks with a doctor. Important precautions for everyone Do not take more than once in 24 hours. Avoid recreational nitrates (“poppers”). Limit alcohol, as it can increase dizziness and low blood pressure. Seek emergency help for chest pain, sudden vision or hearing loss, or an erection lasting more than four hours. If chest pain occurs after taking Suhagra, seek emergency care and tell medical staff you took sildenafil; do not take nitrates. Suhagra is not intended for women or anyone under 18 for erectile dysfunction. A doctor or pharmacist should review your medicines and medical history before you start.

I can explain which precautions are most relevant to you.
