Letinnov is an oral contraceptive that is used to prevent pregnancy. It is a combination of female hormones (ethinyl estradiol and levonorgestrel ) that prevent ovulation (the release of an egg from an ovary). It also causes changes in the cervical mucus and uterine lining, making it more difficult for sperm to enter the uterus and more difficult for a fertilized egg to attach to the uterus.
Letinnov is currently unavailable but you can order a good contraceptive alternative on this page.

Dosage and administration
Take 1 tablet per day orally, as indicated by your doctor.
To achieve a contraceptive effect, 28 tablets are taken in a row, in accordance with the instructions on the blister, usually in the evening.
Initial intake begins on the 1st day of the menstrual cycle for 28 consecutive days. Menstrual bleeding usually occurs after 3 days of using the tablets. Regardless of the end of menstruation, start the next package.
Each subsequent 28-day package is started without a break.
If you miss a pill, you should take it within the next 12 hours. Otherwise, you should continue taking the pills at a specific time of the next day, without taking the missed pill. If you miss tablets, the likelihood of sudden bleeding increases.
