Concerta Feeling Abnormal Causes and Reviews


Chiari malformations (CMs) are structural defects in the cerebellum. The cerebellum is the part of the brain that controls balance. With CM, brain tissue extends into the spinal canal. It can happen when part of the skull is too small, which pushes the brain tissue down. There are several types of CM. One type often happens in children who have neural tube defects. Some types cause no symptoms and don't need treatment. If you have symptoms, they may include

  • Neck pain
  • Balance problems
  • Numbness or other abnormal feelings in the arms or legs
  • Dizziness
  • Vision problems
  • Difficulty swallowing
  • Poor hand coordination

Doctors diagnose CM using imaging tests. Medicines may ease some symptoms, such as pain. Surgery is the only treatment available to correct or stop the progression of nerve damage.

Concerta Feeling Abnormal 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!

My son is 8 and has been on Concerta for 3yrs he is telling me he does not need it anymore so i just stopped is that ok he has been off for 4days the only thing i am seeing is fatigue, please some let me know if this is ok. Kim

Sat, 19 Sep 2009
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.

My son was wheezing with physical complaints of bronchospasm for 60 minutes after gym class ended. He has never had wheezing before this, is 16 years old and has been on Concerta (36 mg/day sustained release) for 2 months. I am notifying the physician today.

My daughter developed "athletes ashma" since being on Concerta, as well as agressive behaviour. I am taking her off!
Fri, 08 May 2009
my bras constipated from Concerta any advice
