"For 6 months I was on the Heather tablet ( made by Glenmark), doing pretty much fine and not noticing any significant side effects. However, when after 6 months I needed to refill my prescription and the pharmacy was out of the Heather tablet, I let them give me what they had, Jencycla (made by Lupin), figuring all minipills were the same. Within a few days I noticed significant changes in my mood, like collapsing into tears at the slightest provocation and getting angry at and suspicious with my boyfriend for stupid reasons. After a couple weeks I started acting crazy and being totally irrational and full of rage, and couldn't control my behavior or moods. Has anyone else experienced such mood swings from changing minipill brands?"
