Detailed Answer:
Hi there,

Invanz is very powerful antibiotic. Generally, it can be used for very complicated UTIs, but it is usually given for 10-14 days, and it is usually given when all else fails.

Like most antibiotics, Invanz will give you diarrhea because it can alter the flora in your GI tract. Essentially, it can kill the good bacteria in the GI tract. Without bacteria in the GI tract, your body can not appropriately break down, digest, and absorb foods and nutrition. This happens with almost all antibiotics so you may have had diarrhea in the past with antibiotics, but just never this severe.

The main concern is that Invanz is one of the many antibiotics that can cause C. Diff diarrhea which an infection of the GI tract frequently associated with antibiotic use, hospitalization, and age. Severity of infection can range from diarrhea to inflammation of the colon, and perforation. It is among the most common cause of hospital acquired infections, as well as antibiotic associated infections. The diarrhea (defined as >3 stools in 24 hours) is very watery, foul-smelling, and sometimes bloody. There is usually significant abdominal pain with C. Diff. The risk of getting it are low and unlikely, but very significant due to the complications associated.

Therefore, the diarrhea is most likely from Invanz killing off the normal GI tract bacteria, and not a C. Diff infection. However, I had to tell you about C. Diff because if you do have it, you should not treat the diarrhea as it can significantly worsen the disease. The chances are low, but very significant.

You should start a probiotic, double your fluid intake, and wash your hands frequently. The diarrhea will clear within a couple days after antibiotics are finished.

Let me know if there's any further queries.
