Brief Answer:
No

Detailed Answer:
Hi,

Thanks for your query.

No, polyethylene glycol when used as laxative does not cause back stools.

Black tarry stools is most often a sign of upper GI bleed. This can be ruled out by a Gastro-duodenoscopy.

Sometimes foods can impart stool the back color if they bear a similar pigment.

Hope, I answered your query.

Wish you good health.

Regards,
