Hello, Thanks for posting your query on Healthcare Magic... * Brief Answer: Increasing the dosage, spacing the drugs or adding a calcium channel blocker are good for non dippers plus regular measures. *Explanation: My opinion is that high blood pressure on many occasions is an indication for control .That happens on many levels. First, be sure that high blood pressure is not secondary to any other diseases as Cushing or renal failure.Then ,Diet with low salt and less fat content is crucial. Exercise and other healthy activities are also a mean to control blood pressure. If all that dose not help, medications are a must .That is usually decided by your doctor according to your condition and comorbidities .Some drugs that are perfect for patients are not necessary good for others.Regular blood pressure monitoring is as important as starting treatment so that we could assess efficacy of the medication we started. I suggest my patients the following : add a calcium channel blocker at night and avoid any caffeinated drinks . *Conclusion: I suggest you consult your physician about your medications. If you have any further questions I will be happy to help, If not, you can close the discussion and rate the answer. Wish you good health.
