About Norinyl-1

Norinyl-1 is a combined hormonal contraceptive used to provide protection against pregnancy. It contains norethisterone, a progesterone and mestranol, an oestrogen as its active ingredients.

Norinyl-1 works by stopping the release of an egg each month from the ovaries, preventing ovulation during the menstrual cycle. It also makes cervical mucus thicker, making it more difficult for sperm to pass through the cervix, and makes the lining of the womb thinner, so fertilised eggs are less likely to implant in the uterus wall.

NowPatient offers the Norinyl-1 birth control pills for the prevention of pregnancy only, following an online consultation with a prescribing clinician.

How and where to get Norinyl-1?

Norinyl-1 is available with a prescription only. It is not available over the counter at a pharmacy.

NowPatient does not allow customers to buy Norinyl-1 directly. Our service is certified, safe and effective, and we only ever treat conditions. If you book a consultation with a prescribing clinician for a contraceptive, you can discuss if Norinyl-1 is a suitable treatment option for you.

At the end of the consultation, the clinician will decide if a treatment plan is suitable for you. If it is, the clinician will issue you with a prescription which can then be ordered, paid for and delivered directly to your chosen address by NowPatient.

Dosage and strength for Norinyl-1 for contraception

Each Norinyl-1 tablet contains mestranol 50 mcg and norethisterone 1mg.

Information about how to take Norinyl-1 for contraception

Take 1 Norinyl-1 tablet each day, at the same time for 21 days. After 21 days, you will take a 7 day break from taking Norinyl-1 tablets. You should expect a withdrawal bleed during your pill-free week. Start a new pack of Norinyl-1 tablets on day 8.

If you forget to take a Norinyl-1 tablet, take the missed pill as soon as you are able to do so. You will need to use extra precautions such as a condom for the next 7 days. Also, read the patient information leaflet or speak to a healthcare professional if you need further medical advice.
