Two synthetic hormones - the active ingredients that make the pill work. The first is ethinylestradiol, the oestrogen hormone. This is available in 20 micrograms and 30 micrograms, the smaller dosage for women who have slight issues tolerating higher doses of oestrogen. The other main ingredient is desogestrel, a synthetic version of the natural hormone progesterone. This comes in 150 micrograms.
