Effexor Loss Of Consciousness Causes and Reviews


Reye syndrome is a rare illness that can affect the blood, liver, and brain of someone who has recently had a viral infection. It always follows another illness. Although it mostly affects children and teens, anyone can get it. It can develop quickly and without warning. It is most common during flu season. Symptoms include

  • Nausea and vomiting
  • Listlessness
  • Personality change - such as irritability, combativeness or confusion
  • Delirium
  • Convulsions
  • Loss of consciousness

If these symptoms occur soon after a viral illness, seek medical attention immediately. Reye syndrome can lead to a coma and brain death, so quick diagnosis and treatment are critical. Treatment focuses on preventing brain damage. There is no cure.

The cause of Reye syndrome is unknown. Studies have shown that taking aspirin increases the risk of getting it. Because of that, health care professionals now recommend other pain relievers for young patients.

Effexor raised my blood presure alot ,I had extreme painful headaches,rash that started on my face which was horrible,then spread to my chest,my neck was beat red I itched so badly.I think docotrs need to be more educated on this med before giveing it out so quickly.
Sun, 17 May 2009
Effexor was horrible for me...as soon as I started it I started having panic attacks worse than ever (supposed to help them) scary bad dreams, waking up in a sweat and not knowing who I was, then depression. The first day I expeirenced the panic attacks fast heartrate, I called my Dr. and he assured me that it could not have taken effect that fast, not true! He told me to keep takin the medicine, I trusted his word until I ended up in the hospital feeling like I was loosing my mind. I ended up going into a very deep depression. This was many years ago but I read some of the post and thought I would share my experience. If your told that there is no way that you could be feeling any interactions on the first day, use your own judgement, I trusted my Dr's word and I almost died.
Sat, 11 Jun 2011
I Lost my children because of this drug, i almost took my own life and a life of someone very close to me, I also have liver damage, who do these people think they are making these and giving them to people?
Wed, 02 Dec 2009
Effexor amp; Pristiq is poison - I would know, I started taking it at 16 yrs old, instead of counselling I was given Effexor by a 'psychiatrist drug dealer' I was never offered counselling. I spent of $25,000 on this medication in my lifetime. Discontinuation Syndrome has been my worst nightmare. The brain zaps are disgusting. I wish I could get all of the people who hate venlafaxine together to sue these pharmaceutical companies. They have earnt billions of dollars off the suffering of us and we are the only ones who pay.
