Hi,
There is no direct indication that an increased dose of Cymbalta, or
duloxetine, can cause marble-like stools. However, duloxetine can cause gastrointestinal side effects, such as
constipation or diarrhea, which may affect the consistency of bowel movements. It is important to talk to your healthcare provider about any changes in bowel habits, as this may be a sign of an underlying medical condition or a side effect of medication.
It is also possible that the change in bowel habits may be related to other factors, such as changes in diet or the use of other medications, including those for
high blood pressure. Again, it is important to discuss any changes in medication with your healthcare provider to ensure that they are safe and effective for you.
If you experience any other symptoms, such as
abdominal pain, cramping, or
rectal bleeding, it is important to seek medical attention right away, as these may be signs of a more serious underlying condition.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
