Description of Micronor

Micronor is an oral contraceptive containing Norethindrone as its active ingredient. You can buy Micronor in the form of oral tablets, containing 0.35mg of Norethindrone Acetate. The tablets also contains inactive ingredients including povidone, magnesium stearate, lactose and corn starch.

Indications & Dosage of Micronor

Micronor is used by women for the prevention of unwanted pregnancy. Since it does not have any estrogen, it can also be referred to as a ‘mini-pill’. Norethindrone is a progestin hormone that prevents a woman from becoming pregnant by changing her womb lining and cervical mucus, so that the egg does not meet the sperm, fertilization does not take place, and a fertilized egg does not get attached to the womb lining. Usually, Micronor is prescribed to women who are not able to take estrogen. This drug can also be used for decreasing blood loss and pain during menstrual periods, and also to maintain regularity of periods.

You can take one Micronor tablet every day. To achieve maximum effectiveness, take the tablet at the same time each day. You will need to take the tablets continuously, without maintaining gap between the pill packs.
