How Should Tri-Legest Fe Be Stored?

Keep Tri-Legest Fe tablets in their original package. The packaging is designed to help you remember to take the tablets each day and in the correct order. Keep the package at room temperature, away from moisture and heat.

What If I Miss a Dose of Tri-Legest Fe?

Missing doses of Tri-Legest Fe 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 Tri-Legest Fe Dosing). If you are not sure what to do, refer to the patient information that comes with each pack of Tri-Legest Fe or consult your healthcare provider.

How Does Tri-Legest Fe Work?

Tri-Legest Fe is a "combined" oral contraceptive, 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 pill used today. Generally, combined oral contraceptives are more effective than progestin-only birth control pills.
The hormones in Tri-Legest Fe prevent pregnancy primarily by stopping ovulation (the maturation and release of eggs from the ovaries). However, it also works to prevent pregnancy in two other, minor ways. Tri-Legest Fe 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. It also alters the lining of the uterus (the endometrium), making it less receptive to an embryo.
Tri-Legest Fe is known as a triphasic birth control pill, which means that there are three different "phases" of pills in each pack, plus the last week of tablets (which does not contain any hormones). Each week of Tri-Legest Fe tablets contains a different amount of hormones. This is why it is important to take the pills in the correct order.
Like most birth control pills, each pack of Tri-Legest Fe contains 21 active tablets, which contain the hormones, followed by 7 inactive tablets, which do not contain any hormones. The last seven tablets, however, do contain iron (the chemical symbol for iron is Fe). The iron may help prevent anemia due to blood loss during your period.
