Fildena 50 you mean sildenafil 50 mg, it is generally not dangerous to combine with a small/moderate amount of alcohol, but it’s best to avoid heavy drinking. Alcohol itself can make it harder to get or maintain an erection, reducing sildenafil’s benefit. A few important points: Avoid getting drunk when taking Fildena 50 , because alcohol and sildenafil can both contribute to dizziness or low blood pressure. Do not take sildenafil with nitrates (such as nitroglycerin/GTN) or “poppers” containing amyl nitrite—the combination can cause a dangerous drop in blood pressure. The usual sildenafil dose for erectile dysfunction is 50 mg, and it should generally not be taken more than once in 24 hours. If you develop chest pain, fainting, severe dizziness, or an erection lasting more than 4 hours, seek urgent medical attention. If you tell me how much alcohol you plan to drink (e.g., 1 beer, 2 drinks, several drinks) and whether you take any other medicines, I can tell you how concerning that combination is.
