Malegra Pro 100 mg, which contains Sildenafil (like Viagra), is generally considered safe for most people when used as directed. However, combining it with alcohol can increase the risk of side effects. Alcohol can:

Lower blood pressure: Both alcohol and Sildenafil have vasodilatory effects, meaning they can both lower blood pressure. When taken together, they might cause a significant drop in blood pressure, which could lead to dizziness, lightheadedness, or fainting.

Reduce effectiveness: Alcohol can impair sexual performance and reduce the effectiveness of Sildenafil, making it harder to achieve or maintain an erection.

Increase side effects: Alcohol may heighten some of the common side effects of Sildenafil, such as headaches, flushing, or dizziness.

For safety, it's best to limit alcohol consumption when taking Malegra Pro 100 mg. If you plan to drink, moderate amounts are recommended, and you should avoid excessive drinking to reduce the risks. Always consult a healthcare provider if you have concerns about combining alcohol and this medication.
