Since it is a chewable tablet, taking it without water is simple. Alcohol and large meals should be avoided right before taking Fildena XXX since they may lessen its effectiveness. Unless prescribed by a physician, the suggested dosage should not exceed one tablet daily. Sexual stimulation is still necessary even though this medicine helps improve blood flow for better erections.
