The "PM1 yellow pill" likely refers to Aurovela 24/4 Fe, a birth control pill that contains the active ingredients ethinyl estradiol and norethindrone acetate. It is a combination oral contraceptive and is colored yellow.
What are the active ingredients in Aurovela 24/4 Fe?
Aurovela 24/4 Fe contains two hormones: ethinyl estradiol, which is an estrogen, and norethindrone acetate, which is a progestin. These hormones work together to prevent pregnancy by stopping the release of an egg from the ovary and by thickening the cervical mucus, which makes it harder for sperm to reach the egg [1].
How does Aurovela 24/4 Fe work to prevent pregnancy?
Aurovela 24/4 Fe prevents pregnancy through a combination of actions. Primarily, it inhibits ovulation, meaning it stops the ovaries from releasing an egg each month. Additionally, it alters the cervical mucus, making it thicker and less permeable to sperm, and it can also affect the lining of the uterus, making it less receptive to a fertilized egg [1].
What is the difference between Aurovela 24/4 Fe and other birth control pills?
Aurovela 24/4 Fe is a monophasic oral contraceptive, meaning each active pill contains the same combination and dosage of hormones. It is a 28-day regimen, with 24 active yellow pills and 4 inactive (placebo) pills. Other birth control pills may have different hormone combinations, dosages, or regimen lengths, such as multiphasic pills (where hormone levels change throughout the cycle) or extended-cycle pills that reduce the frequency of periods.
When does the patent for Aurovela 24/4 Fe expire?

Are there generic versions of Aurovela 24/4 Fe available?
As patents expire, generic versions of birth control pills become available. Generic versions of combination oral contraceptives containing ethinyl estradiol and norethindrone acetate are available, offering a more affordable alternative to the brand-name product.
What are the potential side effects of taking Aurovela 24/4 Fe?
Like all oral contraceptives, Aurovela 24/4 Fe can have side effects. Common side effects may include nausea, breast tenderness, headache, and changes in menstrual bleeding.
