Take Norlut-N exactly as prescribed by your doctor. Swallow the tablet whole with water, with or without food, and do not crush or chew it. For best results, take your dose at the same time every day. The exact directions depend on your treatment goal: to delay periods, it is usually started 3 days before your expected period; for other menstrual issues, it is taken daily on specific days of your cycle. If you miss a dose, take it as soon as you remember, but skip it if your next dose is almost due. Never double your dose.
