If you’ve ever wondered why certain drugs (Zyprexa, Avandia, Seroquel, Cymbalta…to name a few) seem to have something in common, but you just can never really put your finger on it, well, it’s time to look to the Kevin Bacon Game (aka, Six Degrees of Separation, with some liberties taken) to find out what those connections are…so here goes…
A new study out yesterday—June 1, 2010—has revealed a higher rate of miscarriages in women who were taking antidepressants during pregnancy. How much higher? Sixty-eight percent—yes —that’s 68%—higher. Frankly, that is nothing short of shocking.
Published in the Canadian Medical Association Journal, the study was done in Canada through the University of Montreal. FYI—This was no small study either—the investigators used data from 5,124 women who are part of a large, population-based study of pregnant women who had clinically verified miscarriages, and a large sample of women from the same registry who did not have a miscarriage. Among the women who miscarried, 284 or 5.5 percent, had taken antidepressants during their pregnancy.
In fact the findings are so robust that the physicians who did the study are suggesting that this is a class effect—in other words the effect could be attributed to all selective serotonin reuptake inhibitors—or SSRIs. Here’s what’s being reported in the press:
“These results, which suggest an overall class effect of selective serotonin reuptake inhibitors, are highly robust given the large number of users studied,” the study’s senior author, Dr. Anick Berard, said in a statement. (UPI.com)
The antidepressants that showed a particular association with miscarriage in the study were paroxetine (trade names: Seroxat and Paxil) and venlafaxine (trade names: Effexor, Efexor, Alventa, Argofan, Trevilor). The investigators also found that the risk of miscarriage doubled with a combination of different antidepressants.
Just for the record, the antidepressants “investigated” in the University of Montreal study are serotonin reuptake inhibitors (citalopram, fluoxetine, fluvoxa-mine, paroxetine and sertraline); tricyclic antidepressants (ami-triptyline, clomipramine, desipramine, doxepin, imipramine, nortriptyline, trimipramine), Read the rest of this entry »
These days, there are many drugs to keep track of. It’s not just the brand name drug anymore; patients could be taking a generic equivalent. So, this week, Pleading Ignorance looks at the SSRIs and SNRIs to give you the brand name, manufacturer, generic version and the generic’s manufacturer. Consider it your one-stop cheat sheet on some of the more commonly prescribed antidepressants.

The information in the chart above was found at either drugs@fda, or on the individual drug manufacturer’s website. As far as I can tell, this information is correct as of the date it was written—and it is not intended to replace the information you might receive from your doctor or medical practitioner (hey, have to say it, we’re a legal site). Talk to your doctor or pharmicist for medical advice.
C’mon. You know you’ve seen that Pristiq ad once or twice—the one with that little wind-up doll (yes, the one with the circa-1970’s get-up that would drive any of us into a state of mild depression)—and you’ve thought to yourself, “Gee, I’ve had days when I kind of felt that way”. Admit it folks, you’ve been there—maybe not in mauve polyester, but you’ve been there.
Now, you may or may not have taken that thought to the next level: the “I need help” level. Most of us don’t. But if you have, you’ve most likely “talked to your doctor” as only “he can determine whether [fill in anti-depressant drug name here] is right for you”.
And if you’ve left your doctor’s office with a little slip of paper to be dropped off at the pharmacy, you may have been prescribed an SSRI, SNRI, NDRI or MAOI. Perhaps you’re feeling high as a kite on the hopes that you’ll be giddier than a glee club as soon as you get that scrip filled. But, take pause. For while you fantasize about your future mental state, do you really know what you’ve just been given?
What follows is a mini primer to the world of anti-depressants—and, as this is a legal news site, the links provided will lead you to information on safety concerns and some of the resulting litigation that’s gone on.
There are actually many different types of antidepressants. Not just the brand names, but the actual types of drugs themselves that work on different chemicals in the brain. Generally, antidepressants aim to reverse depressive symptoms and stabilize mood by increasing the amounts of certain chemicals that are found in the brain. The type of antidepressant depends on the chemicals being affected.
Although there is no one answer to the question, “What causes depression?” scientists believe that chemicals in the brain play a role in some forms of depression. The brain has several hundred types of chemical messengers—also called neurotransmitters—that send messages between brain cells. Of these, three neurotransmitters specifically are targeted by the various antidepressants, to different degrees.
Serotonin is thought to play a role in controlling anxiety, mood, sleep, sexuality and appetite.
Norepinephrine is thought to play a role in sleep and alertness and is also thought to play Read the rest of this entry »
Although the adverse effects of women taking psychiatric drugs while pregnant related to birth defects and infant withdrawal syndrome are often discussed or reported, the serious adverse effects on the sex lives and reproductive systems of millions of young couples are rarely mentioned.
Whatever the reason, due to the ever widening marketing campaigns by the psycho-pharmaceutical industry, young people need to be warned before they get conned into taking psychiatric drugs. Read the rest of this entry »
