I was just prescribed Vyvanse by my General Physician. I am currently taking Zoloft, 100mg. I have trouble focusing and listening without drifting off mentally. I ve never been technically diagnosed ADHD, but through counseling years ago I was told I am probably borderline ADD. I have suffered with depression and anxiety for years and have been taking Zoloft now for at least 12 years at different dosage levels. I am 58 years old. Ever since I was a young boy I was very talkative and fast paced. I want to know what are the different medications to treat adult ADD, and which ones are best for helping increasing paying attention, listening and focusing on a task and staying on task. And, how do the ADD / ADHD drugs interact with Setraline/Zoloft? I am concerned about side effects increasing depression or worse.
