Some harsh replies here. I vaguely remember pen licenses from when I was at school and remember my “gifted and talented” friend getting hers whilst I (the not gifted and talented taken out for extra support friend) was still scratching away with a pencil. I’m not sure i understand how helpful they are but im not a teacher.
I do adhd reviews as part of my work and I’ve had many children refuse their medication for a variety of reasons. Often the side effects or the fact that they don’t feel like themselves when they’re on the medication. You clearly can’t force him and I imagine his psych would not be agreeable to that. Comparing it to insulin and other life saving medications is really not helpful either.
there’s a few things that I would maybe be suggesting but would depend on school/service capacity.
Could you try arranging a medication review? I sometimes find that after a discussion of why they don’t want to take the medication, why we’re prescribing the medication in the first place and hearing that other children experience the same can be helpful. I’ll often explain to children that some people are just not build for a sit down and listen classroom environment but if the medication can help them get through that without getting into trouble all the time (which will be annoying for them) then they can leave school and do something that will be suited to their strengths and needs and may not need medication anymore.
Are there certain days where it’s more important that he takes his medication than others? If he’s not going to take it every day could it be agreed that he takes it the days he has spelling etc but maybe not the day he has PE and an early finish (again depends on the school).
What other strategies can help him managing his ADHD in the classroom? Wobble chairs, movement breaks, maybe there’s a particular seat that’s more distracting than another, etc.
Have a chat with his teacher as well to find out a bit more about what’s happening - is it actually he’s had his pen license taken away because he was drawing all over the table or chucking the lid about for example - sometimes children can be unreliable storytellers!
sorry for the lengthy reply but I hope you are able to find a solution!
