Adherence to levothyroxine treatment among patients with hypothyroidism in Oman: a national cross-sectional study.

Objective: Hormone replacement therapy with levothyroxine is considered the treatment of choice for hypothyroidism; however, non-adherence is a major contributor to poor treatment outcomes. This study aimed to evaluate levels of drug adherence (DA) to levothyroxine therapy among Omani adults with hypothyroidism and to explore related sociodemographic and clinical factors.

Methods: A national, multi-center, cross-sectional survey was carried out from August to December 2021 at 18 primary healthcare centers across all governorates of Oman.
