TriRegol (ethinylestradiol & levonorgestrel) is a triphasic contraceptive pill (known as ?the pill? or combined oral contraceptive pill) that is used to prevent pregnancy.
Triphasic contraceptive pills contain three different doses of artificial oestrogen and progestogen that need to be taken in the correct order. Some women experience fewer side effects when taking triphasic pills due to the varying hormone levels.
Combined pills can reduce premenstrual symptoms, regulate your periods, and make them lighter and less painful.
