I feel that ritalin (methylphenidate) makes me angry very fast! Is it normal? And how to control my anger?

This can occur BUT. Is not a good thing. This likely means that Ritalin (methylphenidate) is not the optimum medication for you. Please let your psychiatrist/ prescribing medical provider know, so that your medications can be optimized.
Not normal. If you feel extreme anger or rage on ritalin, (methylphenidate) that may not be the right medication for you. Talk with your doctor immediately.
