How do psychiatrists decide between Vyvanse vs methylphenidate?

Both are effective stimulant classes, but they act slightly differently. Vyvanse is an amphetamine based medication that is converted in the body gradually, often leading to smoother onset and offset. Methylphenidate works through a different mechanism and may feel cleaner or more precise for some. Clinically, we look at history, anxiety levels, side effect sensitivity, duration needs, and family response patterns. There is no personality type that matches one better. It is often thoughtful trial and monitoring. If someone feels overly activated or emotionally edgy, we may switch classes. The decision is individualized, not based on internet trends.
