That's a fairly low dose to start with so I don't think you'll have many side effects. Some of the side effects can be increased heart rate, feeling jittery, appetite suppression, and trouble sleeping if you take it too late in the day. You should have a follow up to let Dr know if it is helping or not. There are a lot of ADHD medications but they are not one size fits all.

The biggest side effect (more of a general effect than anything) that I’ve had is crashing after the drug wears off my system. It feels like a sugar crash but on a larger scale. While this is normal for the drug and drug class, if it throws off your mood too much, you should talk to your doctor. But since you’re on a lower dose, the crash effect should be minor or not noticeable.
