Actually, klonopin has been reported to have the side effect of 'bad taste in the mouth' as noted by some of my friends whom have used this medication. And, I have found that studies do not always list all side effects...especially if they are not wide spread among subjects. For years, Paxil was not reported to have a withdrawl effect...but I felt it myself when I quite taking it...and I see now that they are reporting it.
The same COULD hold true for the frequent urination problem...but if you are a male...you should see if you are experiencing enlarged prostrate.
Varapamil could also be the cause of the frequent urination since it is an anti anginal medication and exerts itself on muscle tissue.
These are just possibilities and your doctor will want to investigate further. If it is very bothersome, perhaps other medications could be tried to see if these symptoms subside...but your doctor will have to help you make these discisions.
Good Luck! Please remember to click the 'ACCEPT' button for my efforts to assist you...and/or...provide more information. Happy Holidays! And bonuses & feedback help your rating (& mine)on future questions.
