Adherence to treatment is disappointingly low among patients with chronic health disorders especially after 6 month of initiating drug therapy. In hypertensive patients , as reported by WHO, 50% of non-adherence could be expected. Poor adherence to anti hypertensive medications results in increased morbidity, mortality and costs. One of the reasons that could implicate medications adherence can be attributed to seeing no physical sign of better controlling blood pressure. Self monitoring of blood pressure at home has been reported to improve patients adherence to their medications.
