Fildena Professional contains Sildenafil Citrate, which works by relaxing blood vessels and increasing blood flow. Alcohol also affects blood vessels and can lower blood pressure. When both are taken together, their effects can add up and increase the risk of unwanted side effects. What can happen if combined with alcohol: Increased dizziness or lightheadedness Drop in blood pressure (especially when standing up quickly) Headache and flushing may become worse Reduced ability to get or maintain an erection Slower or weaker effectiveness of the medicine Even moderate alcohol intake (beer, wine, or spirits) can reduce how well the medication works. Heavy drinking increases the risk more significantly and may make the medicine less reliable or unsafe. Safer approach: Avoid alcohol completely when planning to use the medication If you do drink, keep it minimal and give your body time before taking the medicine Always follow a doctor’s advice based on your heart health and overall condition
