Anti-biotics during pregnancy...?

First You have to ask your gynaecologist some antibiotics are not advised during pregnancy

So -- here's the thing. There is no 'research' into this, because there is no way to DO the research. Scientists cannot possibly give random medications to hundreds of healthy pregnant women (and placebos to hundreds of other women) just to see if their babies are more likely to have birth defects or problems. And it's these sort of blinded population based studied that are needed to scientifically 'prove' safety.

Which is why the VAST majority of medications are in pregnancy category C -- meaning that there is no evidence of harm in actual use, but no blinded research studies either. Doctors prescribe Category C drugs EVERY day to thousands of women, when the benefit outweighs any remote, potential risk.

An untreated UTI can be very dangerous to you AND your baby. At best, it will continue to spread and you'll end up in the hospital with a kidney infection, needing even higher doses of stronger antibiotics. At worst, you could end up miscarrying or septic.

Your doctor knows you are pregnant. He prescribed the drug with the safest risk vs. benefit profile. (And I can find nothing that says it should not be taken during pregnancy. Only that it should only be taken where clearly needed and the benefits outweigh the risk. Which, in your case, it appears they do.)

The only opinion that matters is that of the prescribing physician.

Speak to your GP and midwife and they can tell you the truth. If you're breastfeeding and end up with an infection you have to take them. Not treating something could be more dangerous than treating it.

If the accompanying leaflet said not to take during pregnancy, then its safe to say that you should be talking to your ob/gyn about what meds are safe to take right now. You don't want to leave a urine or bladder infection without treatment nor do you want to hurt the fetus in any way so the best answers to this situation are going to come from speaking with your dr. take care.

That would be something you would discuss with the prescribing doctor. We have on idea why he/she chose that over other treatments, or what the status of your UTI is. Trimethoprim is a category C, meaning it should only be used when the benefits outweigh the risks. We don't know why your particular decided the benefits in this case outweigh the risks. Perhaps your UTI is on the verge of becoming a kidney infection and endangering your pregnancy. ASK THE DOCTOR.
