Fildena Double 200 mg is a high-dose ED medication containing sildenafil citrate, the active ingredient in Viagra. It works by increasing blood flow to the penis, helping men achieve and maintain a firm erection during sexual activity. This medication is especially beneficial for men dealing with severe erectile dysfunction, providing effective results that can last up to four to six hours. 
Take Fildena Double 200 as prescribed by your doctor, usually one tablet with water before planned sexual activity. Avoid consuming heavy meals or alcohol before taking the medication, as these can reduce its effectiveness.
It’s essential to consult a healthcare provider before using Fildena Double 200, especially if you have pre-existing health conditions or take medications like nitrates. Side effects such as headaches, dizziness, or flushing may occur, but they’re usually mild and temporary.
