Synphase is a combined oral contraceptive pill used to prevent pregnancy. It also helps regulate periods, reduce menstrual pain and manage hormonal symptoms like PMS.
It contains synthetic versions of oestrogen and progestogen, which prevent ovulation, thicken cervical mucus and alter the womb lining to reduce the chance of pregnancy.
Take one pill daily for 21 days, followed by a 7-day break when your period usually occurs. Start a new pack after the break, even if you’re still bleeding.
Synphase uses a phased or triphasic approach, meaning hormone levels vary through the cycle. This can better mimic natural hormonal changes and suit some women better.
Yes. Many users find their periods become lighter, shorter and less painful when taking Synphase consistently.
No. Synphase only prevents pregnancy. You should still use condoms to protect against sexually transmitted infections.
Missing a pill may reduce effectiveness. Follow the leaflet guidance based on how many pills were missed and when. Use backup contraception if needed.
Some women find Synphase helps clear up hormonal acne, though results vary. It may be prescribed off-label for this purpose by a doctor.
Common side effects include nausea, breast tenderness, mood changes or slight weight fluctuation, especially when first starting the pill. These often settle over time.
