Lo loestrin fe hormone levels?

Lo Loestrin Fe is a low‑dose combined oral contraceptive.

- What it contains:
- Active pills: ethinyl estradiol (EE) 20 micrograms and norethindrone 1 milligram per pill (a progestin).
- Inactive pills: four iron tablets (ferrous fumarate); these have no hormones.

- How it’s taken:
- Typically 24 days of active pills, followed by 4 days of iron-only pills (the pills are taken in order on the pack).

- About hormone levels:
- There isn’t a single, fixed “normal” hormone level for this medication. Blood levels of EE and norethindrone vary by time since the pill was taken and from person to person.
- In general terms, EE in a 20 mcg dose produces relatively low circulating estrogen levels compared with higher‑dose pills; norethindrone levels peak a short time after taking the active pill and decline over the 24-hour period. Exact numbers vary widely between individuals.
- Blood tests to measure these levels are not routinely used to monitor contraception. The pill’s effectiveness is assessed by cycle control and absence of pregnancy, not by checking hormone levels.
