Effexor Agitation 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

Does anyone else feel that Effexor XR doesn't work as well when they are either having a bout of influenza or herpes, or another viral infection?  I get brain zaps even on my normal dosage (150mg/day) if I am experiencing a cold or herpes outbreak.

Tue, 12 May 2009
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.
