Women who try to cure acne with the help of birth control pills should know that this method of treatment comes with its share of severe side effects like

• Heart attack
• Blood pressure
• Headaches as severe as Migraines and strokes
• Blood clotting
• Mood swings and Depression
• Nausea and vomiting
• Breast tenderness
• Problem having orgasms.
• Sudden Weight gain due to increase in the appetite. 
• Diarrhea or vomiting

All these side-effects make this approach to cure acne, not worth it. However if you are already using pill for birth control, you may talk to your gynecologist about FDA approved Ortho Tri-Cyclen and generic norgestimate/ethinyl estradiol)
