What is Lo Loestrin (and what is it used for)?
Lo Loestrin Fe is an oral contraceptive pill. It’s used to prevent pregnancy and (because it contains hormones) can also help with cycle-related issues such as irregular bleeding in some people. [1]
How does Lo Loestrin work?
Like other combination birth control pills, Lo Loestrin Fe uses estrogen plus a progestin to stop ovulation and change cervical mucus so sperm cannot enter the uterus as easily. [1]
What ingredients are in Lo Loestrin Fe?
Lo Loestrin Fe contains hormone pills plus iron-containing tablets in the dosing schedule (the “Fe” indicates iron in the inactive tablets). [1]
How is Lo Loestrin Fe taken?
Lo Loestrin Fe is taken by mouth once daily on a fixed schedule. People typically take active hormone pills for most of the cycle and then take the remaining tablets as directed in the pack schedule. Follow the exact directions from the specific product packaging and your prescriber’s instructions. [1]
Is Lo Loestrin the same as Lo Loestrin Fe vs other “Lo” brands?
There are similarly named oral contraceptives (including generic versions) that can differ by formulation (which hormones and doses) and by how many inactive/iron tablets are included. Confirm you’re looking at Lo Loestrin Fe specifically, not a different formulation with a similar name, and check the “Drug Facts”/prescribing information for the exact product. [1]
Side effects and when to get help
Common side effects of combined oral contraceptives can include breakthrough bleeding, nausea, breast tenderness, headache, and mood changes. Seek urgent care for warning signs associated with blood clots (for example, sudden shortness of breath, chest pain, one-sided weakness, or severe leg pain) or severe allergic reactions. If you’re changing pills because of side effects, discuss the options with a clinician. [1]
How to switch to or from Lo Loestrin safely
Switching birth control pills can affect protection if you skip days or start on the wrong timing. If you’re moving from another contraceptive, the safe start method depends on what you used before (another pill, a patch, a ring, an injection, or a method that doesn’t include hormones). Your pharmacist or prescriber can give a tailored start plan based on your prior method and your cycle timing.
