FAQs
Answers to popular questions about Synphase
What is Synphase?
Synphase is a triphasic combined oral contraceptive pill containing norethisterone and ethinylestradiol. The tablet doses change across three phases during the 21-day cycle: 500 mcg norethisterone/35 mcg ethinylestradiol (7 tablets), 1 mg norethisterone/35 mcg ethinylestradiol (9 tablets), and 500 mcg norethisterone/35 mcg ethinylestradiol (5 tablets). This triphasic design is intended to provide good cycle control while keeping the overall hormone dose relatively low.
How does Synphase work?
Synphase works like all combined oral contraceptives: suppressing ovulation, thickening cervical mucus, and altering the endometrium. The triphasic dosing means hormone levels change across the cycle, which some women find provides better cycle control and fewer side effects. When taken correctly in the right order, Synphase is over 99% effective.
Is Synphase a first-generation pill?
Yes, Synphase contains norethisterone, a first-generation progestogen. This means it carries the lowest VTE risk among combined pills (approximately 5–7 per 10,000 women per year). However, norethisterone has mild androgenic properties, so it may not be the best choice for women prone to acne.
How do I take Synphase?
Take one tablet daily at the same time for 21 days, following the correct order on the blister pack. The coloured tablets must be taken in sequence as they contain different hormone doses. After the 21st tablet, take a 7-day pill-free break during which a withdrawal bleed usually occurs. Start the next pack on the 8th day.
What if I miss a Synphase pill?
Follow standard combined pill missed pill rules. Because Synphase is triphasic, it is especially important not to extend the pill-free interval beyond 7 days. If you miss pills and need to skip the pill-free break, start the next pack immediately with the correct phase of tablets.
What are the side effects of Synphase?
Common side effects include headaches, nausea, breast tenderness, mood changes, and breakthrough bleeding. Norethisterone may cause mild androgenic effects such as acne or oily skin in some women. These side effects usually settle within the first 3 months. Serious side effects such as blood clots are rare.
How can I get Synphase?
Synphase is available on NHS prescription from your GP, sexual health clinic, or through online services like NowPatient. As a triphasic pill, it is typically prescribed for women who have experienced side effects with monophasic pills or who prefer a regimen that varies hormone doses across the cycle.
