Non adherence to medication schedules by patients with chronic illnesses has long been recognized as a problem. The aim of this study is to evaluate levothyroxine (L-T4) compliance, daily dosage and TSH levels under treatment in primary hypothyroid patients.
We included 1636 primary hypothyroid patients over 1 year under L-T4 (F/M: 1469/167, 46±13 years of age) included from 11 tertiary health care centres around Turkey. A survey covers on disease duration, daily dosage, adherence to L-T4 recommendations were performed.
Duration of the L-T4 treatment was 5.9±6.7 years, L-T4 dosage was 96.6 μg/day and 1.3 μg/kg per day, TSH level was 4.8 mIU/l 32.3% of patients were not compliant to the treatment. Compliance rates differs between the centres with a maximum 84% and minimum 55%.
Noncompliant patients have higher TSH (6.9±16 vs 3.8±0.9 mIU/l, P=0.01) and shorter duration of disease (5.8±6.9 vs 6.0±6.5 years, P<0.05) compared to compliant patients. There was no difference of, dosage of L-T4 between compliant and non-compliant patients.
Our results suggest that non-compliance of L-T4 treatment is associated with subclinical hypothyroidism in our study group. Approximately 67.7% of patients follow treatment recommendations but compliance rates differs between the centres. The physicianpatient relationship seems to have key role in adherence to levothyroxine regimen.
