If you are taking sildenafil (Viagra) for erectile dysfunction, do not take any more doses of sildenafil (Viagra) or similar medications such as tadalafil (Cialis) or vardenafil (Levitra) until you talk to your doctor. Because sildenafil is the formulary-preferred agent, most VA providers will prescribe it first. The typical starting dose is 50 mg, taken as needed approximately one hour before sexual activity. While VA healthcare providers may prescribe medications like sildenafil, tadalafil, or vardenafil, these options are not always effective—or even accessible—for every veteran. Erectile dysfunction is common in veterans due to service-related physical or mental health conditions, but typically gets a 0% rating. The VA does however offer compensation for veterans whose erectile dysfunction is connected to their military service, in the form of Special Monthly Compensation. SILDENAFIL TAB has a VA Formualry status of 'Formulary Item' and is within VA copay tier level 1. Sildenafil and tadalafil (PA-F) are available in VHA and on the VA National Formulary for the treatment of erectile dysfunction (ED). Avanafil and vardenafil are non-formulary. The VA prescribes oral medications like sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra) as first-line treatments for erectile dysfunction, with a standard limit of 6 doses per month. There are two different ways to take tadalafil, either daily or on an as needed basis. Talk to your doctor about which dosing schedule is right for you. Tadalafil is sometimes taken as needed, usually at least 30 minutes before sexual activity and not more often than once every 24 hours. The VA today announced it would not add Viagra to its formulary, the drugs that must be available at all VA medical treatment facilities. To meet the VA’s requirements for erectile dysfunction, you’ll need to show that you have a medical diagnosis. You’ll also need to connect erectile dysfunction to your military service.
