Has anyone found really bad side effects from the patch daytrana?

Yes. Daytrana (ritalin (methylphenidate) in a patch) has many side effects, such as rapid heart rate, insomnia, hyperactivity, exacerbation of underlying mental disorders where it used inappropriately, heart attacks and death. Is that bad enough?

No major side effect. The most common side effect that is usually reported to me is a little bit of irritation at the application site.
