Your mother should: be reevaluated for proper treatment of her hypertension. Many patients require more than one drug and/or more than one administration of a drug in a day to achieve acceptable results. Effective treatment at this age will avoid significant complications and untoward events in the future. See you health care provider for reevaluation.
