Hi, may I answer your health queries right now ? Please type your query here... I am a 52 year old female and recently was diagnosed with life-long untreated ADHD. I was prescribed 20mg Adderal xr once daily and have been taking it for about 4 months. I have been thrilled with the difference it has made in my ability to function as a normal human being. Suddenly and without warning, I began to experience abdominal cramps at work. When I went to the restroom, I noticed some blood drops after urination. A few minutes later, I felt the need to go again and this time there was more blood. After about an hour, I had been to the restroom about 8 times and each time the bleeding and cramping were worse. I went to the ER and they did a CT scan and urinalysis. After about two hours there, the bleeding spontaneously stopped and by the next day I seemed fine. Tests indicated no infection. Could this episode have been caused by the adderall? If so, is it an isolated incident? Can I safely continue taking Adderall or is there potential risk.
