Hello,
As per my clinical experience, the 
Biaxin is  a strong 
erythromycin antibiotic. It is used in variety of skin and 
respiratory tract infections with excellent outcomes in terms of recovery. However, many side effects pause a threat to its use and prime one is GI upset with loose stools and 
vomiting (though less). The usual time period varies from 1-2 weeks for regaining of the bowel 
incontinence episodes. Following measures will help for faster recovery:
- Plenty of liquids including oral rehydration salt
- Continue pre and pro biotics
- Prefer fresh curd to supply GI flora
- Avoid all spices, non veg, junk foods
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Bhagyesh V. Patel, General Surgeon
