Effexor Disorientation Causes and Reviews


Have you ever felt dizzy, lightheaded, or as if the room is spinning around you? If the feeling happens often, it could be a sign of a balance problem. Balance problems can make you feel unsteady. You may also have blurred vision, confusion, and Disorientation. They are one cause of falls and fall-related injuries, such as a hip fracture.

Some balance problems are due to problems in the inner ear. Others may involve another part of the body, such as the brain or the heart. Aging, infections, head injury, certain medicines, or problems with blood circulation may also cause balance problems.

It is important to see your doctor about balance problems. They can be a sign of other health problems, such as an ear infection or a stroke. Your doctor may send you to a specialist for a diagnosis. You may need a hearing test, blood tests, or imaging studies of your head and brain. Other possible tests look at your eye movements, and how your body responds to movement.

In some cases, treating the illness that is causing the disorder will help with the balance problem. Exercises, a change in diet, and some medicines also can help.

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.

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.
