Hi doctor, I am 83 yrs. young, I daily have to take an anti-depressant pill named PRISTIQ - DESVENLAFAXINE 50 mg. and as I have also incontinence, my eurologist asked me to try and take MYRBETRIQ - MIRABEGRON 25 mg daily, I would like to know if these two medications are alright to take by me or that the latter might have side effects by taking them together? and if the latter can cause problems in my bladder and might cause some damage there, and later cause for me to have a bag to urinate in, etc.?
