Thank you for your query.
The drug has been correctly prescribed to reduce the spasmodic pain of IBS
. As you have not mentioned the duration of the problems and for how long you have been taking this medicine it is not possible to give you an appropriate guidance. I suggest that you let the medicine act for a week or two more otherwise consult your doctor who may like to review the diagnosis and/or the medicine.
I hope I have answered your query to your satisfaction.
Wishing you all the best.
