Hi! I'm 17 and I've been on Strattera for about 5 months. I started w/ 25 mg. and then moved up to 40 mg. for about 4 months and everything was fine and I could see improvements in my concentration...but then I tried 60 mg. and everything seemed good for a couple weeks and then all the sudden I started having some horrible side effects. I now can't sleep good @ night, feel energyless, get depressed or in a bad mood often, feel emotionaly numb, often feelings of hopelessness, and tired all day long. I went back to 40 mg. 2 days ago and I now feel somewhat better. I just started school this week and have noticed @ around 1:30 or so I feel the effects of the medicine wearing off and by my last period class I can't concentrate @ all... I thought Strattera worked 24 hours a day??? It seemes to only work 6-7 hours after I take it and after that I get extremely sleepy and just slip into a horrible mood and all the above symtoms... Also I'm still having trouble sleeping and still feel energyless and tired every day. I mean, I feel a little better but not signifficantly... How long does the 60 mg. take to leave your system? Should I just give it more time? How come even though I went back to 40 mg. I still have these side effects?:confused:

Strattera has a half-life of about 5 hours, as does its active metabolite. There seems to be a sort of "halo effect" where Strattera continues to work some, even past declining blood levels. Nevertheless, it is recommended that adults take Strattera twice a day. I would recommend trying 30mg twice a day and see how that works out for you.

Good luck

Have you talked about this with your doctor at all?
