Can Antibiotics Taken For UTI Cause Vaginal Infection And Cervical Insufficiency?

I am 25 weeks pregnant, at 21 weeks I had a UTI and my cervix measured short. At 22 weeks I went in to see the doctor because I was having contractions and my cervix measured short again 1.4 cm, I was given something against the contractions and something against vaginal infection. I went to my appointment last week and my cervix measured normal at 4.8 cm. My question is, do you think that the antibiotics I took for the UTI might have caused a vaginal infection that caused cervical shortening? (I had vaginal itch that felt like might be an infection) I am going away for the weekend and my doctor is on vacation this week he said that it was ok for me to go away, I feel fine. I have an appointment with him on Monday. Should I worry? I am still taking Nifedipine against contractions until Monday.

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

When premature labor pains occur that can lead to shortening of cervix and when your pains subsided with tocolytics your cervix might have came to normal length. Antibiotics will not cause vaginal infection but the urinary tract infection can spread and lead to vaginal infection that can lead to irritability of the uterus and pre mature onset of labor pains. Better to continue the tocolytic drug prescribed by your doctor and follow with regular antenatal check ups.

Hope I have answered your query. Let me know if I can assist you further.
