MCT oil smells bad

Been using MCT oil before I go to bed for the past two days, it’s all fine but when I wake up in the morning it smells a little unpleasant, like rancid coconut or something like that. Maybe I’m applying too much or leaving it on too long. The pharmacist gave me some emollient he recommended but not sure if I can partner that with the ketoconazole and the MCT because at a certain point it’s just too much. Thanks
