Vyvanse (lisdexamfetamine) : Vyvanse (lisdexamfetamine) is a drug that is converted to an amphetamine-like drug in your body. This is a stimulant. It can help people with adhd when prescribed by a doctor. Stimulants tend to cause construction of blood vessels. If the arteries and vein tissue in a man's penis constricts, he will loose his erection. This is temporary and should wear off in a day or two. If it doesn't, you should see your doctor or a urologist. Dr. Stan myers nw urological clinic portland, or.

Erectile : Erectile dysfunction is listed as a common side effect of vyvanse (lisdexamfetamine). Dr myers, the urologist, did a great job explaining the physiology behind this. Ok, now some input from a psychiatrist. Why are you taking a controlled substance if is was not prescribed for you? If it had been prescribed to you, you would have been provided information from the pharmacy that filled it, listing common side effects. Stimulants have potential serious side effects - you should not take them unless you have been diagnosed with a specific condition for which it is indicated.
