Hi Thanks for posting your query . There are no documented evidences that either Co 10Q, magnesium or hawthorn berry. So I don t recommend you to stop BP medications and go on these . Instead what you can do is continue your BP medicines , start taking hawthorn berry , keep doing aerobic exercise and follow low salt diet . Keep a track on your BP . If it s anything less than 120/80 ask your doctor to reduce the dosage of Avalide . Keep continuing your diet and exercise and after 1 month of reducing the dosage of Avalide if your BP is still less than 120/80 ask your doctor to stop Avalide . After 2-3 months the same can be tried with Metoprolol . Warning : NEVER STOP BP MEDICATIONS BY YOURSELF . IT WILL CAUSE REBOUND ACCELERATED HYPERTENSION . Any clarifications feel free to ask . Happy to answer.
