Irritatingly, last month I went to buy a pack of Mercilon pills from my local pharmacy in Beijing and they didn’t have it. Not only did they not have Mercilon, but they had a shelf full of Marvelon. Ugh. I just switched from Marvelon to Mercilon because it looked like all the pharmacies no longer carried it. And now it’s available again.

4 boxes of Marvelon birthcontrol

So now I’m going to try to go back to Marvelon. I bought 4 boxes, so I can be set for a while. They are 32.8元 per box. That’s almost half the price of Mercilon. More importantly, I have felt like my moods have been more severely up and down with Mercilon and also my skin has been breaking out almost constantly. I blame the pill, but who knows. There are always other factors with these things.

I found this advice on switching, which seems the same as going the other direction:

Switching Pills – {21 day to 21 day} Changing to combined preparation containing different progesterone (21 day combined preparations) continue current pack until last tablet and start first tablet of new brand the next day. If a seven day break is taken before starting new brand, additional precautions (barrier methods) should be used during the first 7 days of taking the new brand.

So there you go. Hope this works out.
