Most women take one pill per day for 21 days, then take a four or seven-day break before starting the next pack. You’re likely to experience a withdrawal bleed during this time. This looks like a period, but it isn’t.
Norinyl-1 can also be taken as follows:
Tricycling: Take one pill every day for nine weeks without stopping. Take a 4 or 7-day break after 9 weeks (3 packs of pills) and then restart the cycle.
Take 1 pill every day without missing a dose.
Take 1 pill every day for at least 21 days for a flexible extended use. Take a four-day break if you experience excessive bleeding. Start taking the pill every day on the fifth day, and don’t take another break for at least 21 days.
Norinyl-1 contains hormones that prevent your ovaries from releasing an egg (mestranol and norethisterone) (ovulation). They also make it more difficult for sperm to reach an egg or for an egg to implant in the womb lining.
Norinyl-1 is 99 percent effective in preventing pregnancy when taken correctly. Approximately 9 out of 100 women will become pregnant if it is not always taken correctly.
You may not be protected against pregnancy if you are vomiting or have severe diarrhoea. Continue to take the pill as usual if this happens, but use a condom while you’re sick. If this lasts longer than 24 hours, you should take the same steps as if you missed a pill.
Please note that Norinyl-1 should only be used if you are certain you are not pregnant.
If you start taking Norinyl-1 on the first five days of your period, you should be safe from pregnancy right away, assuming you don’t have a short or irregular menstrual cycle.
If you have sex after day 1 and have a short/irregular menstrual cycle, you must use condoms for 7 days. If you have sex in the first 7 days, your clinician will be able to tell you if you need to use additional contraception.
Many women do not have any negative side effects, but some do. Headaches, nausea, breast discomfort, irregular bleeding, and mood swings are some of the symptoms. Blood clots occur in a small percentage of women. The risk of blood clots is slightly higher with this pill than with others. Send us a message through your Patient Record if you have any concerns.
See the patient information leaflet for a complete list of side effects and how to use it correctly. If you have any concerns about side effects, please contact us through your Patient Record.
This is dependent on how many pills are missed and when they are missed. Contraception is not jeopardized by missing one pill at any time. If you miss two or more pills, or if you start a new pack late, your contraceptive coverage may be affected.
If it’s been more than 48 hours since you last took a pill, take the next one as soon as you remember and finish the rest of the pack as usual. This may necessitate taking two pills on the same day.
More than 48 hours – this is dependent on when you took your last pill and where you are in your pill packet. For more information, please see the patient information leaflet.
A Norinyl-1 prescription can be requested and paid for online. Even if you use an online service, you will need a prescription from a clinician to purchase this medication because it is a prescription-only medication.
To safely prescribe any combined contraceptive pill, we will need to know your height, weight, and blood pressure. This can be completed during the consultation.
If you’ve already purchased your pill from us, you can request a new supply from your Patient Record if you’re medically eligible. Please send us a message through your Patient Record if you want to change your pill.
Blood pressure can rise as a result of combined contraceptives, which can be dangerous. Before starting any combined contraceptive, your blood pressure should be checked, and then once a year after that. If you’ve recently had your blood pressure checked or checked it yourself with a home blood pressure monitor, you can tell us about it during your consultation.
Norinyl-1 should be safe to take with other medications. However, it’s critical that you tell us about any prescription, over-the-counter, or recreational medications you’re taking so that we can safely prescribe Norinyl-1.
NuvaRing, Evra Patch, combined pills, low-dose pills, and mini pills are among the contraceptives we offer. Take a look at all of our contraception options.
