Hi,
It is unlikely to be due to Mucinex-DM. Its common side effects include
drowsiness, headache, nausea and
vomiting. It is unlikely to cause urine incontinence. Based on the history you seem to have developed
stress incontinence apparently caused by cough.
Urinary stress incontinence occurs when an activity such as coughing, sneezing, or exercising causes a small amount of urine to leak from the urethra, which is the tube urine passes through. There is nothing to worry, it will subside once the cough subsides.
Meanwhile, I advise you to drink less fluid, take fiber diet to avoid
constipation, avoid alcohol (if you consume) and caffeinated drinks, avoid spicy foods and drinks that may irritate your bladder. If you have
diabetes, keep your blood sugar under good control.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
