Norinyl-1 is typically prescribed as a contraceptive pill, but the combined pill has other uses and beneficial effects for which it can be used for. Some women find that the pill makes their periods lighter and more regular. It can also help to relieve symptoms of endometriosis.[1]

What is Norinyl-1?
A 21-day pill. So you take it, starting on the first day of your period if you can, once a day for 21 days.
Norinyl is a combined contraceptive, which means it contains two hormones. These hormones tweak your menstrual cycle a bit, so you don’t ovulate. They also thicken your cervical mucus so sperm can’t reach your eggs (in the unlikely event any are released) and make your uterine wall a little less sticky so an egg can’t implant.
Yes. All combined contraceptive pills go through rigorous testing before they get released for use. There is a risk of side effects with all pills. These tend to be pretty common during the first few weeks of use but settle down once your body gets used to the new hormones.

Yes. All combined contraceptive pills go through rigorous testing before they get released for use. There is a risk of side effects with all pills. These tend to be pretty common during the first few weeks of use but settle down once your body gets used to the new hormones.
How effective is Norinyl-1?
We know. The main thing you’re likely to want to know about Norinyl-1 birth control is whether or not it’s effective. The short answer is ‘yes’. The slightly longer answer is ‘over 99% effective if you use it right’. That basically means that out of 100 women using over a year perfectly, less than one of them will get pregnant.
Of course, you have to take it right for it to work properly (as in, every day, ideally at the same time), but taking the pill every day is a habit that most people find easy to get into.
If you make the odd mistake with Norinyl-1, which is easy to do, that’s called ‘typical’ use. In this case it’s 91% effective (so 9 in 100 women taking it this way will get pregnant over a year).

How to take Norinyl-1
Take one pill a day, at the same time, for 21 days. Then have a seven day break and start your next strip. Repeat.
Each tablet should be swallowed whole with water. It can be taken with or without food.
A strip of Norinyl contains 21 tablets, each of which has the day of the week labelled above it. This allows you to keep track of what you have taken. At the end of the 21 day course, you will take a seven day break, during which you will likely experience a withdrawal bleed.
As with all medications, following the instructions of your prescribing clinician and the patient information leaflet is essential.

More common side effects tend to be mild and short-term (so they’ll pass after using the pill for a couple of months).
These include: nausea, weight gain, headaches, mood changes and irregular menstrual bleeding.
When to see a doctor
What alternatives are there to Norinyl-1?
Quite a few. Not all combined contraceptive pills are the same. Some contain different hormones or are different dosages. But all combined pills have the same level of effectiveness when it comes to preventing pregnancy. The main difference is how suitable they are for controlling menstrual symptoms.
Norinyl-1 is fairly unique in that no other pill contains the exact same hormones in the exact same amounts.
So if you get side effects on Norinyl-1 and want to switch, it will be to a somewhat different pill.
If you find the combined contraceptive pill does cause unwanted side effects, the mini pill may be more suitable. It’s very nearly the same level of effectiveness, but doesn’t contain oestrogen, making it more suitable for those with toleration issues.
