Concerta Aggression Causes and Reviews


Caring for someone who has Alzheimer's disease (AD) can be stressful and overwhelming. It's important to take care of yourself. Ask for and accept help.

Talk to the doctor. Find out what treatments might help control symptoms or address behavior problems. Find a support group. Others who have "been there" may be able to help and will understand.

If there are times of day that the person is less confused or more cooperative, take advantage of that in daily routines. Consider using adult day care or respite services. These offer a break with the peace of mind that the patient is being taken care of. Begin to plan for the future. This may include

  • Getting financial and legal documents in order
  • Looking into assisted living or nursing homes
  • Finding out what your health insurance and Medicare will cover

Concerta Aggression Reviews

Fri, 15 Jul 2011

I took ONE dose-----my head, face and ears itched. My face became all blotchy and swelled up. The skin on my forehead and cheeks started to peel, as if I had a sunburn. $40 I spent to take one pill----which was nothing but POISON. Don't use Concerta!

You put your kid on amphetamines when he was 6? Wow dude, that's horribly inappropriate. A lot of kids who show even strong signs of ADHD grow out of it. I didn't start using Concerta till just a few days ago, and I'm 19. I wish I had this through highschool to be honest, but I'm glad I didn't have to take it as a child. It's good you are letting him stop using it though. There shouldn't be any withdrawal effects as far as I know.

It should be o.k, he's probably experiencing fatigue as a drawback from being off Concerta. Concerta can cause imsomnia (the loss of sleep), but given enough time he should recover. If there are more severe symptons he experiences such as pain then going to the doctors would probably be recommended.
