Fildena 150 mg, it contains sildenafil, but 150 mg is above the usual maximum recommended sildenafil dose of 100 mg for erectile dysfunction. It isn't expected to work substantially faster simply because the dose is higher. Standard sildenafil generally starts working in about 30–60 minutes, and a heavy/fatty meal can delay the onset. A higher dose can instead increase the risk of headache, flushing, dizziness, low blood pressure, indigestion, and visual disturbances. I would not recommend taking 150 mg without a doctor specifically prescribing it. Also, don't combine it with other ED medicines such as Penegra, Suhagra, Vigora, Silagra, Cenforce, tadalafil/Tadacip, or Tadarise. If your goal is faster onset, I can explain the safest ways to optimize sildenafil timing (including food and timing) rather than increasing the dose.
