Lactose free letrazole

Hi does anyone know of a brand in UK that does lactose free letrazole, ? 

I do have enzymes but I've checked how much of the ingredients is in the pills I need to take & there is more lactose then actual hormone stuff, 45 mg of lactose, 2 mg of letrazole.

I've got to take it for 2 years , , 

I have taken pills in the past ( contraception) that had lactose in it ,so had to take enzymes it's just not good for my insides , , 

I will have a chat with oncologist but I've not found anything on  medical sites ,so thought I would ask here, 

Thanks
