Kamagra 50 mg contains sildenafil 50 mg (a PDE-5 inhibitor used for erectile dysfunction). Combining it with alcohol is not usually recommended, especially in larger amounts. Small amounts of alcohol may not cause a serious problem for many healthy men, but alcohol can make sildenafil work less effectively by reducing sexual response and can increase side effects. Heavy drinking with sildenafil may increase the risk of: Dizziness or light-headedness Low blood pressure Fainting Headache and flushing Difficulty getting or maintaining Kamagra 50 mg erection Avoid alcohol and sildenafil together if you have heart disease, low blood pressure, or take medicines that affect blood pressure. Never combine sildenafil with nitrate medicines (such as nitroglycerin for chest pain). If you tell me your age, how much alcohol you usually drink (e.g., 1–2 drinks vs heavy drinking), and whether you take BP/heart medicines, I can give more specific guidance.
