Suhagra 100 mg (sildenafil 100 mg) can be safe for some elderly men, but it depends much more on the person’s heart health, other medicines, and overall condition than on age alone. Sildenafil has been studied in older men and is generally well tolerated when used appropriately. For an older man, a doctor may consider factors such as: Heart condition: Men with unstable heart disease, recent heart attack/stroke, or chest pain requiring nitrates should not use sildenafil without medical clearance. Blood pressure medicines: Sildenafil can lower blood pressure, and extra caution is needed with some drugs (especially nitrates and certain alpha-blockers). Kidney or liver problems: Older adults may need dose adjustments if kidney or liver function is reduced. Starting dose: Although 100 mg is a commonly used maximum dose for many adults, some older men may be advised to start with a lower dose depending on their health and medications. Common side effects include: Headache Facial flushing Dizziness Indigestion Vision changes (such as a bluish tint) Do not combine Suhagra with: Nitroglycerin or other nitrate heart medicines Recreational “poppers” (nitrates) If you tell me the man’s age, whether he has heart disease, diabetes, high blood pressure, and what medicines he takes, I can give a more specific safety assessment.
