Cenforce 100, which contains sildenafil citrate, can be effective for treating erectile dysfunction in men over 50. However, due to age-related health concerns like heart disease, diabetes, or high blood pressure, medical consultation is essential before use. Avoid alcohol and grapefruit juice, which can intensify side effects. Take it only as prescribed—usually 30 to 60 minutes before sexual activity, not more than once a day. Possible side effects include headaches, dizziness, flushing, or vision changes. Never mix it with nitrate medications or other ED drugs. Regular health checkups and lifestyle adjustments can improve its effectiveness and safety.
