Loestrin Fe Dosage

The only Loestrin Fe dosage available for preventing pregnancy is one tablet taken once a day, at the same time every day. However, the medication is available in two different strengths, one with a slightly higher dose of hormones. It is important to know exactly what to do if you miss any Loestrin Fe doses, as missing doses increases your chances of pregnancy.

Loestrin Fe Dosage: An Introduction

It is important to take Loestrin® Fe (norethindrone/ethinyl estradiol) exactly as directed. As always, do not adjust your Loestrin Fe dose unless your healthcare provider specifically instructs you to do so. Although the drug is effective when taken as directed, not taking it correctly increases the risk of unintentional pregnancy.
Loestrin Fe comes in two different strengths: Loestrin Fe 1/20 (a lower dose of hormones) and Loestrin Fe 1.5/30 (a slightly higher dose of hormones). Your healthcare provider will choose the best Loestrin Fe dosage for you based on several factors, especially your response to other birth control pills in the past.
(Loestrin Fe is not the same as plain Loestrin® or Loestrin® 24 Fe. The information in this article does not apply to either of these medications.)

Loestrin Fe Dosage for Birth Control

Starting 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 (this may take a little planning, as you will need a new pack ready), even if you are still having your period.
The first 21 tablets contain the active ingredients. The last seven tablets do not contain any hormones, although they do contain a little iron (which may help prevent anemia from blood loss during your period). During this last week, your body gets a little break from the hormones, allowing you to have a period. Sometimes, you may have breakthrough bleeding or spotting between periods. When this happens, keep taking Loestrin Fe as usual.
