welcome to HCM.
The dry mouth you have been experiencing is do the Solitral.
Solitral is a combination of solifenacin
Solifenacin is an Anticholinergic
which is help in treating urinary incontinence
. But it also reduces the salivary production and there by leads to dry mouth. Dry tongue, dry eyes, dizziness
etc are also some other common side effects of solifenacin.
Taking plenty of fluids should help you. But that might cause your bladder to overfill and might cause you pain.
If the dryness is severe enough then stop using it and see your doctor ( preferably Urologist
) for an alternative or further course of treatment.
Hope you got the answer you were looking for.
