What If I Take a Leena Overdose?
Women who take too much Leena may experience the following symptoms:
- Nausea and vomiting
- Vaginal bleeding or other menstrual irregularities.
Keep Leena tablets in their original package. The packaging is designed to help you remember to take the tablets each day and to take the pills in the correct order. Keep the package at room temperature, away from moisture or heat.
Keep Leena and all other medications out of the reach of children.
What If I Miss a Dose?
Missing doses of Leena increases the risk of pregnancy. What you should do depends on how many tablets you have missed and where exactly you are in your cycle (see Leena Dosing)
. If you are not sure what to do, refer to the patient information that comes with each pack of Leena, or consult your healthcare provider.
How Does Leena Work?
Leena belongs to a group of birth control pills
known as combined oral contraceptives
, which means that it contains two different types of hormones. It contains both an estrogen (ethinyl estradiol) and a progestin (norethindrone). Combined oral contraceptives are the most common type of birth control pills used today.
Leena is also a "triphasic" birth control pill, which means that there are three different "phases" of pills in each pack (plus the last week of tablets that does not contain any hormones). Each phase has a different amount of the progesterone hormone. This is why it is very important to take the pills in the correct order.
Most importantly, the hormones in Leena prevent pregnancy by stopping ovulation (the maturation and release of eggs from the ovaries). However, it also works to prevent pregnancy in two other, minor ways. Leena changes the cervical mucus (the fluid of the cervix, which is the lower, narrow part of the uterus that is connected to the vagina), making it more difficult for sperm to enter the uterus. Lastly, Leena alters the lining of the uterus (called the endometrium), making it less receptive to an embryo.
