Tulana (norethisterone) is a progestin-only oral contraceptive used by women to prevent pregnancy.
Indications for use
This medication is used to prevent pregnancy.
Mechanism of action
Norethindrone is a hormone that prevents fertilization by making vaginal fluid thicker to help prevent sperm from reaching an egg and changing the lining of the womb to prevent attachment of a fertilized egg. As a result, a fertilized egg passes out of the body. This drug also stops ovulation in about half of a woman’s menstrual cycles.
Dosage and mode of application
To achieve maximum contraceptive effectiveness, take these tablets exactly as directed. Take 1 tablet every day, at about the same time. Do not skip tablets, do not make interruptions between Tulana packs. Take these tablets with a glass of water, with or without food.

What if I miss a pill?
Try not to skip any tablets. Every time you miss a tablet or take it late, your chance of pregnancy increases. If you miss 1 tablet, take it as soon as possible and keep on taking 1 pill daily at the regular time (use an additional non-hormonal method of birth control for the next 48 hours). If you miss more than 1 tablet, use an additional non-hormonal method of birth control for the rest of your pack. Contact your doctor if you missed more than 1 tablet.
Visit your doctor regularly for checks on your progress. Have a regular breast and pelvic exam and Pap smear while on the pills.
Use an additional non-hormonal method of birth control during the first cycle that you take Tulana.
If you think you are pregnant, stop taking these pills immediately and consult your doctor.
If you are taking this drug for hormone related problems, improvement in your condition may occur only after several cycles of use.
The product does not protect you and your partner against HIV infection or any other sexually transmitted diseases.
