Terbutaline was originally approved for usage by the U.S. Food and Drug Administration for the treatment of asthma symptoms. It acts to relax muscles. It has never been approved for use as a drug to prevent labor (a tocolytic drug).
The manufacturer of terbutaline (sold under brand names of brethine and bricanyl) has never sought labeling approval for use as a tocolytic and, in fact, its labeling has specifically stated that it was not approved for treatment of pre-term labor.
Despite such labeling and despite the absence of clinical trial data which would support the efficacy and safety of the use of terbutaline as a maintenance tocolytic (usage of greater than 48 hours), for over 20 years obstetricians have been using terbutaline in such an off-label manner to slow or prevent pre-term labor.
Recent studies relate terbutaline usage to autism. The possibility of such a link has been recognized for some time.
There may be more than one cause of autism. That does not exonerate terbutaline as a cause.
You know this really makes me very angry and I know alot of that anger comes from my own personal experience with being lied to by providers and knowing that they most of the time spew crap. They spread fear and crap! And if you don't go along with what they are recommending or if you question in anyway you get the old "dead baby" card. All a mother needs to hear is "your baby could die" and most of the time it works. Well I am sorry not on me. NOT ANYMORE! Birth is as safe as life gets. There is NOTHING in life that has a 100% guarantee why should anyone expect birth to be 100%. I was given this drug in my second pregnancy as they thought I was in early preterm labor, now looking back I know it wasn't labor but at the time I was a good girl, the good patient that did everything her OB/CNM told me to do and I NEVER questioned if this drug was safe for me or baby. I just assumed that if it wasn't approved for it they wouldn't use it. Wow such a crock of shit!
