If Aurogra 100 mg contains sildenafil 100 mg, age alone doesn't automatically prevent an older adult from using it. However, 100 mg is usually not the dose to start with in someone aged 65 or older. For adults over 65, prescribing information recommends considering a 25 mg starting dose, because sildenafil remains in the body at higher levels in older adults. D DailyMed +1 If 25 mg is effective and well tolerated, a clinician may increase the dose to 50 mg and, when appropriate, 100 mg. H HRES PDF Sildenafil should never be combined with nitrate medicines such as nitroglycerin or isosorbide because of the risk of a dangerous blood-pressure drop. D DailyMed Extra caution is appropriate if the person has heart disease, low blood pressure, significant kidney/liver problems, or takes alpha-blockers or multiple blood-pressure medicines. So, for an older adult, Aurogra 100 mg may be used in some circumstances, but it generally shouldn't be the first dose without medical assessment. If you tell me the person's age, blood-pressure reading, and regular medicines, I can explain whether 25, 50, or 100 mg would generally be the safer starting range.
