2. What Are the Side Effects?
"Every drug has its toxicity," as the saying goes. Strictly speaking, sildenafil belongs to a type of vasodilator, so its side effects are naturally related to vascular reactions, such as headaches, facial flushing, blurred vision, dizziness, and so on. However, these reactions are generally temporary and will resolve or disappear on their own after a period of time.
Although Viagra rarely causes severe side effects, men should still avoid excessive use and follow the instructions.
Upon reading this, many people might have another question: if you take too much Viagra, will it become ineffective?
