Effexor Irritability Causes and Reviews


For most adults, moderate alcohol use is probably not harmful. However, about 18 million adult Americans have an alcohol use disorder (AUD). This means that their drinking causes distress and harm. It includes alcoholism and alcohol abuse.

Alcoholism, or alcohol dependence, is a disease that causes

  • Craving - a strong need to drink
  • Loss of control - not being able to stop drinking once you've started
  • Physical dependence - withdrawal symptoms
  • Tolerance - the need to drink more alcohol to feel the same effect

With alcohol abuse, you are not physically dependent, but you still have a serious problem. The drinking may cause problems at home, work, or school. It may cause you to put yourself in dangerous situations, or lead to legal or social problems.

Another common problem is binge drinking. It is drinking about five or more drinks in two hours for men. For women, it is about four or more drinks in two hours.

Too much alcohol is dangerous. Heavy drinking can increase the risk of certain cancers. It can cause damage to the liver, brain, and other organs. Drinking during pregnancy can harm your baby. Alcohol also increases the risk of death from car crashes, injuries, homicide, and suicide.

You may have an AUD if you can answer yes to two or more of these questions:

In the past year, have you

  • Ended up drinking more or for a longer time than you had planned to?
  • Wanted to cut down or stop drinking, or tried to, but couldn't?
  • Spent a lot of your time drinking, or recovering from drinking?
  • Felt a strong need to drink?
  • Found that drinking - or being sick from drinking - often interfered with your family life, job, or school?
  • Kept drinking even though it was causing trouble with your family or friends?
  • Given up or cut back on activities that you enjoyed just so you could drink?
  • Gotten into dangerous situations while drinking or after drinking? Some examples are driving drunk and having unsafe sex.
  • Kept drinking even though it was making you feel depressed or anxious? Or when it was adding to another health problem?
  • Had to drink more and more to feel the effects of the alcohol?
  • Had withdrawal symptoms when the alcohol was wearing off? They include trouble sleeping, shakiness, Irritability, anxiety, depression, restlessness, nausea, and sweating. In severe cases, you could have a fever, seizures, or hallucinations.

If you have any of these symptoms, your drinking may already be a cause for concern. The more symptoms you have, the more serious the problem is. If you think you might have an AUD, see your health care provider for an evaluation. Your provider can help make a treatment plan, prescribe medicines, and if needed, give you treatment referrals.

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.
