Brethine not given for PTL AND Asthma???

Published

I'm a nursing student in my maternal child rotation. In one of my lectures, we learned that Brethine is to be avoided in pt.s with preterm labor AND asthma. I don't understand the rationale for this. Brethine is given to pregnant women with asthma for acute attacks, and it is used to stop contractions in preterm labor. I don't understand why it is avoided in patients with both: asthma and in preterm labor? Can someone explain the rationale for this to me? :confused:

Never heard of that.

I know that Hemabate shouldn't be given to patients with asthma, but I've given Terb to lots of women, and have never asked if they have asthma before administering it. Isn't terb used for asthma? I don't understand why they would say it would be contraindicated.

In fact, when I was pregnant I frequently used a nebulizer with Albuterol, and I found that one of the nice side effects of it was that it stopped my preterm contractions.

Exactly!...that's my question! Terb is not contraindicated in pregnancy (except near delivery since it's a tocolytic). It is given to pregnant women with asthma and given to stop preterm labor...I have no idea why I'm being told that when a women with asthma is in preterm labor that you can't give brethine?!! I'm waiting for a response from my professor, and I'll be happy to share what I find out. Thanks for replying.:nurse:
