Male, Age : 31-40 years old , Reason : Hypertension. Side Effects : Frequent urination at night time about 3-4x/ sleeping time... Review : Been on Norvasc 5mg since i find out that i got a HBP @ 34 and i did not realize that my frequent urination at night might have something to do with Norvasc until now @ 39 coz i visited my Doc again for a check-up coz my bp isn't on the level of 120/80...it is still much higher at 135/85 or 140/90 so, my Doc prescbribe me with an additional med atenolol 50mg...it works fine now, so..i had to cut it back at 25mg with the same effect...my bp is now at very normal range at 110 or 120 over 80 or 75 and to my surprise, the plus effect of atenolol was better bladder control during sleeping time...
