Alcohol can cause a drop in blood pressure, and when combined with Tadalista , this effect can become more pronounced. Consuming excessive alcohol with the medication can result in symptoms such as dizziness, fainting, flushing, headaches, and even heart palpitations. Also, alcohol can independently reduce your ability to achieve or maintain an erection, undermining the very purpose of taking Tadalista. It's best to limit yourself to one or two drinks if you plan to consume alcohol.
