Areas › Focus, starting, and ADHD › Medication and how it works
If a tablet seems to have worn off by mid morning, or a low dose feels overwhelming, report it as a pattern rather than as a failure. It usually points to timing, or a different formulation, or a different molecule, rather than to the whole class being wrong for you. The same person can also handle one molecule easily and another badly, so one poor experience does not close the subject.
This explains how treatments work. Never start, stop or change a medication because of something you read here.
You will not be blamed if you make a mistake, only for what your hearts deliberately intend (Quran 33:5). Trying something that turns out not to suit you is not a fault of yours.

ٱدۡعُوهُمۡ لِأٓبَآئِهِمۡ هُوَ أَقۡسَطُ عِندَ ٱللَّهِۚ فَإِن لَّمۡ تَعۡلَمُوٓاْ ءَابَآءَهُمۡ فَإِخۡوَٰنُكُمۡ فِي ٱلدِّينِ وَمَوَٰلِيكُمۡۚ وَلَيۡسَ عَلَيۡكُمۡ جُنَاحࣱ فِيمَآ أَخۡطَأۡتُم بِهِۦ وَلَٰكِن مَّا تَعَمَّدَتۡ قُلُوبُكُمۡۚ وَكَانَ ٱللَّهُ غَفُورࣰ ا رَّحِيمًا
Name your adopted sons after their real fathers: this is more equitable in God’s eyes––if you do not know who their fathers are [they are your] ‘brothers-in-religion’ and proteges. You will not be blamed if you make a mistake, only for what your hearts deliberately intend; God is most forgiving and merciful

A systematic review of pharmacogenetics found that genetic variants explain some of the variation in how adults respond to methylphenidate, but not enough to guide prescribing in practice. So the variability is real and partly biological, and there is no test yet that spares anybody the trial and error. Expect finding the right fit to take a few adjustments.

Strength of evidence: one line of research. A single study, or a theoretical account.
How fast a body breaks a drug down decides how much is present and for how long, and that differs from person to person.
Side effects that frighten you deserve a call straight away rather than a wait for the next appointment.
The skin patch comes with two things worth knowing before you start. Take it off several hours before bedtime or it keeps delivering and sleep goes, and around one person in six gets a rash bad enough to stop.
Worry about height is one of the commonest reasons families hesitate. The answer is to measure: height and weight plotted at every review, so you are watching an actual line rather than guessing at one.
If you open atomoxetine capsules to mix the contents into food, keep it away from your eyes and wash your hands afterwards. The powder stings badly.
