Tri-Legest Fe dosing guidelines are the same for every woman -- one tablet once a day. It is important that you know exactly what to do if you miss any pills, as this increases your risk of pregnancy. In some cases, you may need to use a backup method of contraception (such as condoms) if you miss a Tri-Legest Fe dose.
Tri-Legest Fe Dosing: An IntroductionThere is only one standard dose of Tri-Legest® Fe (norethindrone/ethinyl estradiol). As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so. Although birth control pills are extremely effective when taken correctly, their effectiveness decreases significantly if you take them incorrectly.
(Tri-Legest Fe is a generic version of Estrostep® Fe birth control pills. The information in this article also applies to Estrostep Fe.)
Tri-Legest Fe Dosing BasicsStarting at the beginning of the pack, take one tablet daily, at the same time each day. Each pack will last for 28 days (four weeks). After you finish one pack, immediately start a new one the next day. Do not let any days pass between packs, even if you are still having your period (this may take a little planning, as you will need a new pack on hand). The first 21 tablets contain the active ingredients. The last seven tablets do not contain any active ingredients. During this last week, your body gets a little break from the hormones, allowing you to have a period.
Tri-Legest Fe is a "triphasic" birth control pill, which means that there are three different phases of pills, plus the last phase of the inactive pills. These pills contain different amounts of hormones and must be taken in the correct order. This is why it is important to keep the pills in the original packaging.
