What is Synphase?
Synphase is an oral contraceptive pill, which is commonly known as 'the pill'.
It is taken to prevent pregnancy in women. Synphase is what is called a combined pill because it contains two different hormones, a progestogen called norethisterone and an oestrogen hormone called ethinylestradiol.
When taken correctly the combined contraception pill is over 99% effective at preventing pregnancy.
How dos Synphase work?
Synphase works to prevent pregnancy by preventing an egg from being released from the ovaries.
Synphase also thickens the fluid in the cervix, which makes it much harder for sperm to enter the uterus and fertilise an egg that may have already been released.
Additionally, Synphase will reduce the build-up of the endometrium (wall of the uterus), which normally happens during a menstrual cycle. By reducing this build-up, it is far less likely that any fertilised egg will be able to grow inside the womb. An added benefit of this medicine is that it will work to make your periods lighter.
Please remember, an oral contraceptive pill like Synphase will only work to prevent you from getting pregnant. It does not protect you from catching sexually transmitted infections (STIs). You will still need to use a condom for this kind of protection.
How to take Synphase
Synphase comes in packs of 21 tablets, which should be taken in a specific order:
- Take the blue tablets for the first 7 days.
- Start to take the white tablets straight after you have taken the blue ones. You will take these for 9 days.
- Take the rest of the blue pills for a further 5 days after finishing the white ones.
- You will take one tablet every day for 21 days, then have a 7 day break where you do not take any tablets. During this break, you will have a normal withdrawal bleed.
Providing you start to take this medicine during the first five days of your period, you will be protected from pregnancy straight away. If you start to use Synphase tablets later in your menstrual cycle than this, you will need to use a condom for the first week of taking this medication.
Swallow the tablets whole with a drink of water.

How do you take Synphase?
Our pharmacists and prescribers follow NICE guidelines when prescribing Synphase.
To effectively prevent pregnancy, you must take Synphase tablets exactly as your doctor or pharmacist has instructed you. Please read the patient information leaflet thoroughly before you start taking it. Talk to your doctor or pharmacist if you are still unclear about anything.
Each pack of Synphase contains 21 tablets:
- Seven blue tablets
- Nine white tablets
- Five more blue tablets
Each colour contains a different dose of hormones. When taken in the correct order, they will mimic the natural rise and fall of your body's hormones during the menstrual cycle.
One tablet should be taken each day in the right order. Swallow the tablet whole with a drink of water. Do not crush or chew them.
You can take this medication with or without food. This pill can be taken at any time of day that is convenient for you. However, you must take it at the same time each day.
What if I miss a pill?
If you have missed one pill, take it as soon as you remember, then take your next pill at your usual time. This may mean that you need to take more than one pill in the same day.
If you are later than 12 hours in taking the pill, or you have missed more than one pill, you may not have full contraceptive protection. You should take the last pill you missed and carry on taking Synphase as usual. However, use an extra method of contraception, such as a condom, for the next seven days.
If you have fewer than seven tablets left in a pack after forgetting to take one, finish that blister pack then start the next one without your usual break. This may mean you do not get a period until you have finished two blister packs, but this will not do you any harm.
What if I take more than I am supposed to?
If you have taken too many tablets, you may suffer vomiting, vaginal bleeding or breast swelling. Call 111 or go to A&E as soon as possible if you have taken more Synphase than you were supposed to.

Taking these medicines alongside this combined pill may cause increases in liver function blood test results.

Synphase contains lactose. If you have been told by your doctor that you are intolerant to some sugars, talk to your doctor or pharmacist before you start using this medicine.
Oral contraceptives and cancer
You must tell your doctor or pharmacist if you are currently suffering with any type of cancer, or if you have had cancer in the past.
All women are at risk of developing breast cancer. This risk is rare in women under the age of 40 and the risk increases as women age.
Breast cancer is found to be slightly more common in women who take oral contraceptives compared to those who do not take them. If you stop taking oral contraceptives, the risk of breast cancer returns to normal after 10 years of stopping.
It has not been proven that the contraceptive pill increases your risk of getting breast cancer. It may be that because women who use the pill need to see their doctor more regularly, breast cancer is detected sooner than those who do not take the pill.
Some studies have also suggested that women who take the pill are at an increased risk of getting cervical cancer, although this might be due to other causes.
In rare instances, liver cancer has also been detected in women who are using the combined pill, especially if they have used them for a long time.
Research has shown that the combined pill can work to protect you against ovarian cancer and endometrial cancer.
Risk of blood clots
There is evidence to suggest that women are at a higher risk of developing blood clots (thrombosis) when they take the pill. Blood clots can develop in the veins or arteries, which can increase the risk of a heart attack or a stroke.
Please refer to the Side Effects tab for details on the symptoms that you may have developed a blood clot. You must seek immediate medical attention if you get any of these symptoms.
Always read the patient information leaflet, which will accompany your medication, before you start to use Synphase. If you have any questions, please do not hesitate to speak to your doctor or pharmacist.
Pregnancy and breastfeeding
Do not use Synphase if you are currently pregnant, think you might be pregnant, are breastfeeding or are trying to get pregnant.
If you miss a period while taking this contraceptive pill, tell your doctor or pharmacist straight away. You will need to do a pregnancy test before you can carry on taking it.
Full details on who this medicine may not be suitable for can be found in the patient information leaflet, which will come with your medication. Talk to your doctor or pharmacist if you have any concerns.
