Detailed Answer:
hello and thank you for sending the question.

Antibiotics can sometimes disturb the normal balance of bacteria in our intestinal system. This can sometimes cause a regular bowel movements including diarrhea and fluctuating consistency of stool.

at this point I would continue to observe. You might try obtaining a probiotic supplement over-the-counter at your local pharmacy. This might help to slowly restore normal bowel function.

if you continue to have diarrhea however I would bring us to the attention of your primary care physician. This might be a sign that a pathologic bacteria called C. Difficile may be the cause. this is a bacteria that can sometimes overgrow when individuals are exposed to antibiotics. If this is the case then a different biotic is sometimes used to help restore normal balance in the colon.

thanks again for sending your question. Again consider trying a probiotic supplement. If diarrhea continues or worsens please check in with your primary care doctor.

Thank you again for sending your question.
