Is Rigevidon the same as Microgynon?

Rigevidon and Microgynon are two commonly used brands of combined pill.

They both contain 30mcg of ethinyloestradiol and 150mcg of levonorgestrel, which are the artificial versions of the oestrogen and progesterone hormones. So it's unlikely that you'll notice any difference changing between these brands, they make a good replacement for each other.
