Synphase Tablets

Maximum Quantity Allowed:

Synphase is basically an oral contraceptive and a triphasic combined pill. When used as recommended, it offers up to 99% protection against pregnancy. It contains two active ingredients namely ethinylestradiol and norethisterone that prevent ovulation from taking place during the menstrual cycle. Synphase changes the quantity of norethisterone in a single dose because it's 'triphasic'. But it all depends on a particular point in the cycle. This closely imitates the natural hormonal cycle, which in turn minimises some side effects related to a number of other oral contraceptives.

What Are Synphase Tablets?

Synphase tablets are a type of hormonal contraception that contain two hormones - ethinylestradiol and levonorgestrel. They work by preventing the ovaries from releasing eggs and also thickening the cervical mucus, making it difficult for sperm to reach an egg. Synphase tablets are taken every day for three weeks, followed by a week break, during which you will have your period. The effectiveness of Synphase tablets depends on how correctly it is used.

How Does Synphase Work?

Synphase tablets work by delaying the release of an egg from the ovaries. This happens by blocking the natural hormone progesterone from being produced. Without progesterone, the lining of the womb is not maintained and so a period will start. The active ingredients in Synphase tablets are ethinylestradiol and levonorgestrel, which are synthetic forms of the naturally occurring female sex hormones estrogen and progesterone. These hormones work together to prevent ovulation by changing the cervical mucus, making it difficult for sperm to travel through the uterus and fertilize an egg. Synphase tablets also thicken the lining of the uterus, making it less likely for a fertilized egg to implant. If used correctly, Synphase tablets can be effective at preventing pregnancy.
