Company Comment:  Based on the current available information and temporal association between the use of the product and the onset date of the events, a causal relationship cannot be excluded. Therefore, causality for all events except thyroid function test abnormal s assessed as possibly related, although confounded with patient's Hashimoto's disease and history of fatigue. The event of thyroid function test abnormal  is assessed as unlikely related since it is confounded with patient's Hashimoto's disease.   This case was linked to MOD-2021-309978 (Patient Link).; Sender's Comments: Based on the current available information and temporal association between the use of the product and the onset date of the events, a causal relationship cannot be excluded.
