Synphase and cancer

Do not use Synphase if you have breast cancer, or if you have had it before. Long-term use of hormonal contraceptives may slightly increase your chance of developing breast cancer. Once you have stopped using the Pill for at least 10 years, your risk levels will come back down. Women who are elderly and/or overweight are more vulnerable to breast cancer. Take care using Synphase if a close relative has suffered from breast cancer before. Check your breasts and nipples regularly for any changes or lumps. If you notice anything abnormal, visit your doctor as soon as you can.

Synphase may increase your chance of developing cervical cancer. For this reason, you should have regular smear tests while taking the Pill.

Synphase and blood clots

You may be more susceptible to blood clots while taking Synphase, especially during the first year of use. Talk to your GP before having any operation while taking the Pill. You may need to stop using Synphase to avoid the increased risk of a blood clot in advance of the operation. You are also at a heightened risk of developing a blood clot if you:

• Smoke
• Are obese
• Have a family history of blood clots
• Do not exercise regularly
• Have had a miscarriage in the past
• Have recently given birth

Synphase and other medicines

The following medicines may impact the effectiveness of Synphase:

• Epilepsy medicines (e.g. carbamazepine, phenytoin)
• St John's Wort
• HIV medicines (e.g. nelfinavir, ritonavir)
• Certain antibiotics (e.g. rifabutin, rifampicin)
• Certain antifungal medicines (e.g. griseofulvin)

Starting Synphase

If you have not used any contraceptive with hormones in the previous month:

Start Synphase on the first day of your period. Starting Synphase on the first day of your period means you are immediately protected against pregnancy and do not need to use additional barrier contraceptives.

If you start Synphase any time after day 1 of your period you must use additional barrier contraceptives such as condoms for 7 days.

Switching from another combined hormonal contraceptive pill:

Start Synphase the day after your last pill from your previous pill packet. Do not have a 7-day pill-free break. If you start Synphase after your 7-day break you will need to use an additional barrier contraceptive such as condoms for 7 days.

Changing from a progestogen-only pill, injection, implant or a progesterone-releasing IUD:

You may switch to Synphase, any convenient day, from the progestogen-only pill, from the day of removal of an implant or an IUD and the due date of the injection. In all of these cases, you must use an additional barrier contraceptive such as condoms for 7 days.

After having a baby:

You can start taking Synphase on day 21 after having a baby. If you start taking Synphase later than day 21 you must use an additional barrier method of contraception such as condoms for the next 7 days. You should not take any combined contraceptive pill if you are breastfeeding.

Synphase missed pill

If you forget to take your daily Synphase tablet or you are sick or have diarrhoea within 3-4 hours after taking your tablet, take it as soon as you remember or when you feel better, even if this means taking 2 tablets on the same day.

If you are more than 12 hours late taking your Synphase tablet:

• You will not be protected from getting pregnant and should use additional barrier contraception such as a condom for 7 days.

You are at more risk of becoming pregnant if you miss multiple tablets within one packet or if the missed pill is at the start or the end of your packet. If you think you are at risk of being pregnant while taking Synphase you should speak to a doctor for advice as soon as possible.

If you are less than 12 hours late taking your Synphase tablet:

• You will be protected from getting pregnant. You will not need to use additional contraception.
