Treatment of UTIs during pregnancy is actually quite difficult and requires the advice of an OB. The antibiotics have to be aimed at the most common organism, which is usually E. coli, a gram negative organism. But, the antibiotic must not affect the growing fetus.

The following is taken from the Mayo Clinic website. It discusses antibiotics prescribed during pregnancy, but not specifically which ones to be used for UTI. Selection of the wrong antibiotic can causes severe problems for your wife and baby. You should really have your wife evaluated and treated by an obstetrician.

Good luck.


From the Mayo Clinic

Antibiotics are commonly prescribed during pregnancy. The specific medication must be chosen carefully, however. Some antibiotics are OK to take during pregnancy, while others are not. Safety depends on various factors, including the type of antibiotic, when in your pregnancy you take the antibiotic, how much you take and for how long.

Here's a sampling of antibiotics generally considered safe during pregnancy:

* Amoxicillin
* Ampicillin
* Clindamycin
* Erythromycin
* Penicillin

Certain other antibiotics should be avoided during pregnancy. For example, tetracyclines — such as doxycycline and minocycline — can damage a pregnant woman's liver and discolor a developing baby's teeth.

In addition, it's important to note that two classes of antibiotics commonly used to treat urinary tract infections — nitrofuran derivatives and sulfonamides — have been associated with rare birth defects. Although there's no direct proof that these antibiotics cause birth defects, additional research is needed. In the meantime, use of these medications is still warranted in some cases.

If an antibiotic is the best way to treat your condition, your health care provider will prescribe the safest antibiotic at the safest dosage.
