Aquaban is a licensed medicine that comes in tablet form. It contains two diuretics that help you get rid of the water that builds up in the body’s tissues and cells, relieving the uncomfortable puffiness and tenderness associated with PMS. Aquaban is only effective on water retention that occurs in the days leading up to your period. It should not be taken at other times of the month. If you’re suffering from water retention that isn’t pre-menstrual, you should consider the benefits of new Aquaban Herbal.
