Is Effexor To Blame For My Weight Gain?

QUESTION:

Dear Dr. Heller,

I am a 35 year old female who has suffered from depression since 18 years of age and treated with pharmaceuticals since my mid twenties.  I have been on many types of antidepressants except for the MAOI’s and tricyclics.  At age 29 and following the birth of my twins 3 months prematurely I became devastatingly depressed.  It was a gradual decline that took 10 months before things became critical and required hospitalization.  That is when I was put on Effexor and it saved my life, literally.  Within 2 weeks I was feeling tons better.  Within 6 months I was able to return to work.

I have been on the Effexor for 6 straight years now and have never felt better except for the years prior to 18 y/o.  BUT…I have gained almost ONE HUNDRED POUNDS!  It is so hard to keep my head above water mood-wise when my weight has spiraled, despite my eating habits.  I do experience the usual side effects which at times can be troublesome but not so much so that I have wanted to be off the drug.  I have trouble falling asleep at night, and when I do fall asleep I do not move at all – which makes me very stiff and sore when I wake.  I have terrible somnolence to the point that I’m sure I could fall asleep walking in the corridors at work, or fall asleep talking to someone.  This side effect eases considerably after I have been awake for about 6 hours.  But when I have it, it is absolutely uncontrollable drowsiness.  I yawn constantly.  At the onset of treatment I felt like I had a potato in my throat and had to sleep sitting upright and chew gum even in my sleep.  That side effect subsided but occasionally resurfaces for no reason at all.

The only other side effect I’ve had all through the six years has been chronic gastric reflux.  This has been more or less troublesome at varying times, but over the counter antacids and acid blocking agents have worked well for me.  I also believe the sensation of having a potato in my throat is a referred sensation from the gastric reflux because antacid also would relieve some of the sensation in my throat.  I must add that one of the side effects that was positive for me was the anti-anxiety properties of the drug.  I have suffered from social anxiety my whole life, and in my profession as a nurse (15 years), I have to speak in front of my peers on multi-disciplines.  I’ve always had a sensation of “dying inside” when I have to speak, even to close acquaintances and family, but more so in group situations whether or not I know the listeners.  One day about a year ago, I suddenly realized I was no longer “dying inside” when I was forced to speak.  I still get nervous, but I imagine it to be a “normal” degree of nervousness and not the debilitating anxiety I was always plagued with.  Before it was physically painful and now it’s just a pain in the butt.

Anyway, long story short, I wanted to read your WebPage about Effexor and weight gain but I can’t seem to get to the actual page because the link at the site keeps taking me to the main index page of your website.  If you could give me a direct link to the page I would be most grateful.  Any other information you might be able to add would be helpful as well.  I have become so discouraged with my weight that I have been considering changing medication, but I am terrified at the same time.  I have been well now for 6 straight years and that is the longest period I have been well since my illness began.  The thought of getting sick again in the name of weight loss is terrifying.  Nonetheless, as I am 35 and not getting any younger, being 100 lbs.  overweight is not a good thing.

Please help.

 

ANSWER:

Weight gain is a rare side effect for Effexor, and there have been no reports in the literature about this phenomenon.  If this is due to the Effexor, the FDA needs to know about it. If the Effexor has caused the weight gain, then you’ll need to be treated with alternative medications.  The screening test I use for my patients may give clues to additional diagnoses that might be present.  Effexor treats many diagnosis, especially in high doses.  Side effects are a problem. Post partum depression is often due to low thyroid – which can be worsened on rare occasions by Effexor.  Getting your thyroid checked and treated if necessary is extremely important.

What Do You Think Of The Combination Of Effexor And Zyprexa?

    What Do You Think Of The Combination Of Effexor And Zyprexa?

    QUESTION:

    Dear Dr. Heller,

    Please comment on this combination (Effexor and Zyprexa) of medications for treatment of chronic depression/BPD.

     

    ANSWER:

    Some practitioners describe great results with Effexor, particularly at high doses.  I’ve not had that experience.  In theory this combination should be a good one for chronic depression and the BPD, but in practicality side effects are going to be a huge problem.  In my experience there are better options. Effexor needs to be taken in high doses to get the best BPD effectiveness, usually 300-450mg daily.  At this dose high blood pressure and other side effects can be a problem (nervousness, insomnia, nausea, dry mouth, dizziness and others). Zyprexa is a very effective medication, particularly when the thinking processes aren’t clear.  Weight gain is usually an insurmountable problem for long term use – 25 to 100 pound weight gain is common.  Some people complain that they “have no feelings” while taking Zyprexa.  I use it short term, particularly for those patients who are extremely underweight and have no appetite.

Is Effexor An SSRI Or A MAO Inhibitor?

QUESTION:

Dear Dr. Heller,

I am a Chaplain.  I deal mostly in Critical Incidents counseling and the elderly through Adult Protective Services.  However, I do deal with a great number of people that have a biological disorder.  My wife is Bipolar, she is on 900 mg of Lithium a day and 225 mg of Effexor a day.  My question is this, is Effexor an SSRI drug or an MAOI?  She takes certain over the counter drugs for her sinus at times and they say do not take them if you are using Anti-depressants such as an MAOI.  I am not sure if Effexor is considered an MAOI or not, I thought it was an SSRI.  Now, if it is an MAOI, do you have a suggestion as to what over the counter drug she can take for colds and so forth?  I hope you can clear this up for me.

Thank you for your time.

 

ANSWER:

Effexor is not an MAO inhibitor.  It has different effects on the serotonin, noradrenaline and dopamine systems – depending upon the dose.  It’s not a typical SSRI like Prozac or Paxil however.  Unless high doses of Effexor are being used, there is rarely a problem taking cold medications.  The biggest risk is high blood pressure, since Effexor can raise the blood pressure and some people are sensitive to ephedrine and pseudoephedrine (Sudafed).  Monitoring the blood pressure can determine if a problem exists in this area.

Is Effexor Safe In Children?

Is Effexor Safe In Children?

QUESTION:

Dear Dr. Heller,

I would like to know if Effexor is safe to use in children under the age of eighteen.  It is being recommended to us to help my eight year old son and I’m not convinced it is safe to use at his age.

 

ANSWER:

It is not FDA approved for individuals under 18.  This is a persistent problem in treating children however, as there simply aren’t many studies in children.  It is not known to be safe, and it’s not known to be dangerous.  This is a topic you need to discuss with the physician.

Will Effexor Have Fewer Side Effects Than Paxil?

    Will Effexor Have Fewer Side Effects Than Paxil?

    QUESTION:

    Dear Dr. Heller,

    I am a 19 year old female suffering from panic disorder.  I have had panic attacks the past 5 years but it was only recently that I saw a doctor.  He put me on 20mg of Paxil a day.  I took Paxil for 2 weeks but the side effects were just too much.  Now he’s put me on Effexor.  Does Effexor have lesser side effects like insomnia, loss of appetite and headaches?  I have heard and read that Effexor is a drug used for depression, so will it help me with my panic attacks and agoraphobia?  Please reply back.

    Thanks.

     

    ANSWER:

    When Paxil has side effects it usually means the individual also has the cognitive generalized anxiety disorder (persistent worry).  This appears to be the case with you based on what you described.  The gene has been discovered for this diagnosis, and appears to be related to an elevated serotonin 1A receptor being elevated.  BuSpar is the most effective medication for altering how this gene works, and stopping the cognitive generalized anxiety disorder.  Once the BuSpar is in the system for a few weeks, SSRI medications like Paxil can usually be taken without side effects. Effexor works for some patients with the GAD, and might work for panic. Side effects are a problem with Effexor.

Can You Answer Some Questions About Effexor?

QUESTION:

Dear Dr. Heller,

My 16 year old daughter has recently started suffering from depression and mood swings. She was put on Effexor/capsules and it has helped her with the depression. When we re-filled the prescription they gave us 75.mg tablets and she has thrown up and cried for days. Is there 2 different types of Effexor? Are the withdrawals from the Effexor as much trouble as reports say? I am very concerned about my daughter and need some answers.

Please help….

 

ANSWER:

Effexor can be a difficult medication for many people. Side effects limit their use, including blood pressure problems, profound fatigue, and withdrawal symptoms can be very difficult for lots of people. I’ve found it most successful for chronic pain, although some patients do well with Serzone combined with Effexor, and high doses of Effexor (300-450mg daily) has been shown to work for the BPD.

There are two forms with multiple doses: the regular dose and the sustained release form (“XR”). It could be she was given the short acting form, and it’s also possible the symptoms are completely unrelated to the Effexor – for example a stomach virus. Those with the BPD often have break through dysphoria (anxiety, rage, depression and despair) which also needs to be treated, and this could be the case.
