Malegra 120 contains sildenafil citrate 120 mg (a PDE-5 inhibitor). Whether it is cardiovascularly safe depends on your overall heart health, medications, and risk factors. For many men with stable cardiovascular disease, sildenafil can be safe when properly prescribed. However, 120 mg is above the commonly recommended maximum sildenafil dose of 100 mg, so the risk of side effects may be higher, including: Lowered blood pressure Dizziness or fainting Headache and flushing Palpitations (awareness of heartbeat) Do not use Malegra 120 if you: Take nitrate medicines (such as nitroglycerin or isosorbide) for chest pain Have been advised to avoid ***** activity because of serious heart disease Have had a recent heart attack or stroke (medical guidance is needed) Have uncontrolled high or very low blood pressure Use extra caution and seek medical advice if you have: Severe heart failure Significant rhythm problems Low blood pressure Multiple cardiovascular risk factors (diabetes, smoking, high cholesterol, etc.) If you have heart concerns, a doctor may want to assess your cardiovascular fitness before using higher-dose sildenafil. If you share your age, blood pressure status, heart history (if any), and current medicines, I can help you understand your likely risk level.
