Question: MRSA, Bactrim and Respritory Infection

 momofjdevs - Sat Feb 03, 2007 11:54 pm

Hello all I am Cristal, 35, Female, I am 28 weels pregnant I have had an upper respiratory infection. I was prescribed Bactrim DS by my OB for the MRSA that they detected in my Sputum. I understand that this should kill the MRSA however I don't know the effects on the baby since I am in the last trimester. I was hoping that someone here could help me with that.

Just how bad is it for the baby? Will it cause fetal death?

My past surgeries include, 3 D&C's, 1 D&E, and appendectomy, and I&D, and wound closure. I have a fmaily history of HBP, heart disease.

I am currently on Hycodan for coughing and just finished a round of Augmentin XR for the upper respiratory infection, when they added the Bactrim DS.

User avatar Hello,

Most of the teratogenic effect of drugs occur if they are taken during the first trimester. I am sure that your Doctor is aware of the drugs he is prescribing to you while you are in the last trimester, so you do not have to be stressed.

The following information may be helpful to give you an idea about the safety of the drugs you received in this period on your fetus.

According to the FDA:
Bactrim is considered as a pregnancy category C which means it is not known to be of harm on the fetus, but its effect on folic acid which is important for the fetal development. Thus it should be given according to the physician prescription in conditions which necessitate its use.

Augmentin is considered a drug category B., which means its is not supposed to be harmful to the baby.

Hycodan Tablets is not known whether it can or it can not cause harm to the fetus and is not recommended be many to be used during pregnancy.

Keep in mind that the risk of most of drugs to cause harm to the fetus is mainly during the first trimester.

Follow up with your Doctor is essential.
Best regards.
