Hi Monica, mercilon has the same ingredients as desogen, but slightly different dosage. They both have the same amount of progesterone (desogestrel), but desogen has 30 mcg of estrogen while mercilon has 20 mcg of estrogen. Mercilon is the same as the US pill called mircette.
The pill that is exactly the same as desogen is called marvelon.
Hope that helps!
