###Human: Why does blood pressure change inspite of having drugs? ###Assistant: Hello. So the problem you mentioned are two 1. High blood pressure and 2. Heart rate 1. For BP, continue Diovan (Valsartan) 80 mg. Regarding Atenolol, it does not has many effects on BP, but has an effect of lowering heart rate. If your BP remains elevated, you may increase the dose of Diovan to 120 mg. 2. Take Atenolol 6.25 mg, if heart rate without it remains more than 80 to 90. If the heart rate is below 90, no need to take Atenolol. Moreover, count heart rate manually by counting beats or pulse. Do not rely on what the BP measuring device tells. Remember one thing, sudden stopping of Atenolol increases heart rate beyond normal for a few days, but later it settles to normal. So, be patient.
