What is the latest time of day I can apply Daytrana patch that is supposed to be on for 9 hrs ?

Both insomnia and sleepiness can be side effects. Insomnia is more common. It may be controllable by reducing the dosage and omitting the drug in the afternoon or evening.

That’s the great thing about the patch! You have the control of when and how long the medication will be in her system. It begins working within an hour or two and there is about an hour of effectiveness after it is removed. If our daughter sleeps in on the weekends, we apply the patch and take it off two hours before bedtime. No matter when that is. If you would always have to put it on that late, any adhd med is going to cause severe insomnia, and doesn’t really make any sense to prescribe.
