A reading of 150/70 means your upper (systolic) pressure is still high, even though you are taking Nexovas 20. This can happen due to stress, pain, excess salt, poor sleep, missed doses, or because one medicine alone is not enough. Sometimes the dose needs adjustment or an additional BP medicine is required. Keep checking your BP regularly, reduce salt, exercise, and consult your doctor to review your treatment. Do not change medicines on your own.
