Duac - Where do you store the cream?

The product's package insert states that prior to dispensing, the pharmacist is to store it in a cold place, preferably in a refrigerator, between 2 and 8 degrees Celcius (36 and 46 degrees Fahrenheit). This is why you saw the chemist keep their stock in the fridge.

However, once dispensed, the product will have a 60-day expiration date and it is to be stored at room temperature up to 25 degrees Celcius (77 degrees Fahrenheit). Therefore, you don't need to keep it in the fridge. Just make sure that you store your medication in a place where the temperature does not exceed 25 degrees Celcius.
