What Causes Diarrhea In A Breast Feeding Infant After Having Antibiotics?

Brief Answer:
The causes of persistent diarrhea should be ruled out

Detailed Answer:
Hello

Thanks for the query

I would like to know whether your baby has lost weight during the illness.
Both diarrhea and respiratory infections are common in this age.But as the diarrhea is persistent for a month it should be evaluated.The prolong use of antibiotic can cause diarrhea 1) by destroying the normal flora of the gut which are very helpful in absorption or 2) due to antibiotic associated secondary infection with C.difficile.
The infection by any parasite or C.difficile has been ruled out already by the stool test.
Due to some mechanism in the gut the stool gets it's normal yellow color. Due to rapid movement of bowel there is little time in the gut to change the color of stool from green to yellow.Following diarrhea sometimes it may take 2-3 weeks for the bowel pattern to become regular.In diarrhea there may be transient intolerance to the lactose and if the baby is breast fed then the loose stool may take more time to recover.
As diarrhea is there for more than 2 weeks I would like to rule out the other causes of diarrhea other than infection.As you have mentioned that the stool is greasy,I will get a stool test done for fat globules to rule out steatorrhea(diificulty in absorption of fat) and for reducing substance(to rule out any lactose intolerance).Although the condition like cystic fibrosis is an uncommon cause of diarrhea,I would like to rule it out as there is past history of pneumonia and ear infection.
If the test comes normal I won't be overly worried.
I would be glad to answer if you have any more queries
Regards

Brief Answer:
Tylenol usually does not causes loose stool

Detailed Answer:
Hii

There are various studies and none have shown loose stool as a side effect of tylenol(acetaminophen/paracetamol).
Usually people misinterpret it as a side effect because most of the time tylenol is taken for control of fever(mostly viral) and loose stools are usually due to viral infection.
Although it is usually not advised to stop breast milk if mild lactose intolerance is suspected.But as breast milk also contains adequate amount of lactose,it may need to be discontinued temporarily if the intolerance is severe.
I don't consider it to be a side effect of tylenol.
The stool pattern is improving now(as you have described).It may take few more days to get the bowel pattern regular.
Discuss the need of investigation I have suggested earlier,with your pediatrician.
Wish your child good health
Regards
