question: Good Evening I am working with my Dr. on my High Blood pressure medication. I was taking 25mg of atenolol and half a valsartan 12.5mg and that seemed to keep my blood pressure at bay and level.. She wants me to stop atenolol and am now taking a whole tablet of valsartan. Blood pressure is up and down. After exercise lower but not as low as it was with the atenolol. I did see that that has many side effects and I am sure she is trying what she feels is best for me.. Am now taking half tablet in the morning and half at night. She did suggest taking in the evening. Do you have any suggestions. Try to walk 3 miles a day and am a 68 otherwise healthy woman who has successfully ditched two other blood pressure medications.. Thanks
