What is the Lindynette 20 pill?
Lindynette 20 is a brand of combined oral contraceptive pill (COCP) containing 20 micrograms (mcg) of ethinylestradiol (an estrogen) and 75 micrograms (mcg) of gestodene (a progestin). It is considered a low-dose pill due to its reduced amount of ethinylestradiol compared to older formulations and is primarily used to prevent pregnancy when taken as directed.
Ingredients in Lindynette 20
Along with the active ingredients ethinylestradiol and gestodene, Lindynette 20 tablets contain inactive components including lactose monohydrate, magnesium stearate, colloidal anhydrous silicon dioxide, povidone, corn starch, sodium calcium edetate, quinoline yellow (E 104), and titanium dioxide (E 171).
How does Lindynette 20 work?
Lindynette 20 prevents pregnancy through several mechanisms, similar to other combined oral contraceptives:
- It prevents ovulation by suppressing hormones necessary for egg release.
- It thickens cervical mucus, making it harder for sperm to reach the uterus.
- It alters the uterine lining, reducing the likelihood of a fertilized egg implanting.
How to take Lindynette 20
For optimal effectiveness, Lindynette 20 is typically taken in a 21-day cycle followed by a 7-day break.
- Take one pill at the same time each day for 21 days.
- After finishing a pack, take a 7-day break. You will likely have withdrawal bleeding during this time.
- Start a new pack after the 7-day break, regardless of whether bleeding has stopped.
What to do if you miss a dose
If you miss a dose, follow these guidelines:
- Less than 12 hours late: Take the missed pill immediately and continue as usual. Contraceptive protection should be maintained.
- More than 12 hours late: Take the most recent missed pill as soon as possible and use a barrier method (like a condom) for the next 7 days. Missing pills, especially early in the cycle or before the break, increases pregnancy risk.
Side effects of Lindynette 20
While low-dose pills like Lindynette 20 may have fewer estrogen-related side effects, adverse reactions can still occur.
Common side effects:
- Headaches
- Nausea
- Breast tenderness
- Mood changes
- Breakthrough bleeding
- Weight gain
Serious side effects: Though rare, serious side effects require immediate medical attention. These include symptoms of blood clots (chest pain, shortness of breath, leg swelling), stroke (severe headache, vision changes, weakness), or liver problems (jaundice).
