My son is soon to be 13 and he goes thru all the mind/body specifical changes.

He took Metadate 30 mg since he was 10 and it worked great for him until recently. I do not think he had the same results during the last 3 months of school -it still worked but not as well as it did before.
We did took a break during summer vacation(I read here that it might help, in case the body just got used to it) and tomorow he'll start taking it again for 30 days. I'll keep an eye on him since after the 30 days period is over I have an appointment with his GP for checkup and evaluation.

Now comes my question :
Will the hormonal changes specifical to puberty affect the effect of his medication? How should I approach the issue with his doctor?

I would appreciate any input since he'll start in Junior high this year and I'd like for him to have all the support we can get.

Yes hormones can definitely effect meds. A lot of adults will tell you here that their teen years were a time when their AD/HD really got out of hand.
Just as many adult women will tell you that their meds don't work well during menstrual cycles. Hormones can just throw things off.

Which isn't to say this is the case for everyone. If his doctor is well versed in AD/HD he will know this already, so it shouldn't be a problem. Just keep in good contact with the doctor, and let him know if things aren't working well with the medication. He should be able to make any appropriate adjustments.
Good luck:)

Hormones definately effect ADD -- frequently making problems worse, though occasionally things improve. My ADD improved a lot even without medication when I hit puberty. I was able to manage it with lots of exercise, music, and structure. Frequently hyperactivity symptoms fall off but the impulsivity and inattentiveness is less likely to change. His dosage may need to be changed, if you notice it being less effective.Scattered

Thanks .
Yes, ladym, I know what you mean about women, hormonal changes and ADD. I do not remeber the teenage years to well tho , they're kind of blurry so I guess I did much worse. Pregancy was a better period, but the post partum one-...:faint:

He is not hyperactive. I am afraid he'll do worse actually...
He's GP seemed knowledgeable enough so I hope he'll have the right solution. Yesterday we restarted the 30 mg and he did great -but today he was his old inattentive self again.
