Objective: Inhaled fluticasone is used in asthma for a long duration. However, It’s an adverse effect on glycaemia is debatable. This study explored the effect of inhaled fluticasone in long term asthma patients. A comparative cross-sectional study was conducted among the adult normoglycaemic asthma patients in Bangladesh between June 2017 to May 2018. The study groups were getting inhaled fluticasone for a minimum of three months whereas comparative group were not on any steroids. Each group had 35 eligible participants. Results: In study group, mean plasma glucose at fasting was 5.27 ± 0.48 mmol/L, 2-hour after 75gm oral glucose was 6.04 ± 1.21 mmol/L and mean of HbA1c was 5.57 ± 0.41 % whereas in comparative group these were 5.17 ± 0.59 mmol/L, 5.69 ± 1.09 mmol/L, 5.47 ± 0.40 % respectively (p= 0.25, 0.20, 0.75 respectively). Duration of inhaled fluticasone use had no specific co-relation with fasting plasma glucose, plasma glucose 2-hour after 75gm oral glucose and HbA1c% (r= 0.016, p= 0.46; r= 0.015, p= 0.47; r= 0.019, p= 0.42 respectively).
