    Without a proper history it is difficult to answer your question, as there are many factors to consider with cause, dose, and treatment options.
    There are multiple causes of erectile dysfunction (ED), which is regarded as a natural part of aging. Underlying disease states, such as high blood sugar (diabetes), high cholesterol and blood pressure, and depression can cause it. It is important to control any disease states. ED can also be caused by various prescription medications, as well as nicotine and alcohol(1)
    As you may know, there are two medications that are in the same class of vardenafil and they all work similarly in the treatment of ED. If one does not work a patient should try another drug in the same class. If none of these medications work, there are other options available that you can discuss with your doctor. One choice may be a combination with medication and a pump used to increase blood flow to the penis.(1,2,3)
    You should take vardenafil an hour before activity, and the effects are expected to last closer to 4 hours and up to 6 hours.(4) If you were to eat a fatty meal right before taking this medication, it could decrease the drug’s effects, so it best to take on an empty stomach. On the other hand, grapefruit juice and certain medications can increase drug levels.(5)
    For men older than 65 years, the initial dose is 5 mg/day. The dose range of film-coated tablet vardenafil is 5-20 mg given as a single dose, not more than one time per day. Why did your doctor prescribe the 20 mg tablet and you are taking half? Were you supposed to take the entire 20 mg? Although you are not taking the max dose, I wouldn’t recommend increasing your dose without seeing your doctor. Your doctor may suggest you increase to the whole 20 mg tablet in order to see benefits again. Guidelines recommend that you see an urologist now that current therapy is not beneficial, as these symptoms could be a sign of an underlying disease.(1,2,5)
