..Im currently taking norethindrone and my doctor instructed for three months to not take the placebo week and on the fourth month take the placebo week. I thought norethindrone only had active pills and no placebo week. What is the point of not taking the last week for three months and going to next pack? Is it a waste to throw away three weeks of pills? I am also taking 100 mg of topiramte twice a day for migraines with aura and seizures.
