Starting ADHD medication is the beginning of a long process, not the end of one. Regular reviews are how a GP makes sure the medicine is still doing its job and is still safe for you.
Heart and blood pressure
ADHD medicines can raise heart rate and blood pressure a little. For most people the change is small, but it is checked at each review, and more closely if there is a personal or family history of heart problems.
Sleep and appetite
Reduced appetite and difficulty falling asleep are among the most common side effects. They are often managed by adjusting the timing or type of medicine. Weight is usually tracked, particularly early in treatment.
Mood
Some people notice irritability or a flat feeling as a dose wears off. Anxiety can also become more visible once ADHD is treated. These are worth raising, because they can usually be addressed.
Whether it is still working
The simplest question matters most: is the medication still helping with the things it was started for? Needs change with work, study and life stage, and treatment should change with them. Seeing the same GP across years makes these conversations easier and more accurate.
Monitoring is what keeps a good start from drifting.
