"I started taking the pill at 11 years ago to help with dysmenhorrea (really painful periods) and after trying a few different pills to find one that worked for me I started using Yasmin.  I used Yasmin for many years and it worked very well for me.  Recently my insurance company decided that they would cover Zarah but not the Yasmin so my pharmacy switched me and told me that they were the same pill. When you look at the monograph included with the pills the only noticeable difference is with the non-medicinal ingredients so I agreed to the switch.  I wish I hadn't.  When I first started Zarah I was nauseated on and off for about a month.  Then I noticed that I was getting quite bloated.   My weight has gone up 2 or 3 pounds."
