What is Lo Loestrin Fe?

What is Lo Loestrin Fe used for?

How Lo Loestrin Fe works

Lo Loestrin Fe is a combination medication that contains two hormones: norethindrone (a progestin) and ethinyl estradiol (an estrogen). These hormones work together to prevent pregnancy by:

  • Stopping ovulation (release of an egg from the ovary)

  • Changing cervical mucus to block sperm movement

  • Changing the lining of the uterus so it's less likely for a fertilized egg to implant

Lo Loestrin Fe also includes inactive (hormone-free) tablets that contain ferrous fumarate. This iron supplement is added to lower your risk of anemia during the days you might have your period while taking the inactive pills.

Pharmacist tips for Lo Loestrin Fe

pharmacist
  • Set an alarm to help you remember to take Lo Loestrin Fe at the same time every day. If you miss pills, your risk of getting pregnant goes up if you’re sexually active.

    • If you're starting Lo Loestrin Fe for the first time, take the first blue tablet within 24 hours of when your period starts. If you start later, use a non-hormonal backup method for the first 7 days.

      • Know what to do if you miss a dose of Lo Loestrin Fe. Follow the instructions in your pill pack or ask your gynecologist — what you should do depends on which pill you missed, when you missed it, and how many pills you missed.

        • Spotting or light bleeding while taking Lo Loestrin Fe is normal. It doesn’t mean the pill isn’t working. Keep taking a dose every day and talk to your gynecologist if the bleeding is heavy or doesn’t stop.

          • Lo Loestrin Fe can interact with other medications. Let your gynecologist or pharmacist know about everything you're taking, including over-the-counter medications and supplements.

            • It’s not recommended to breastfeed while taking Lo Loestrin Fe because it might lower your milk supply. If you’re nursing or planning to breastfeed, talk to your prescriber about your options. They can help you decide what’s best for you and your baby.

              • If you haven’t had a period yet after giving birth and start Lo Loestrin Fe, use a non-hormonal birth control for the first 7 days. You need to take 7 blue pills in a row before relying on it for pregnancy prevention.

                • You might not get your period while using Lo Loestrin Fe, and that can be normal. But if you miss two periods in a row, talk to your prescriber to rule out pregnancy.

                  • Get a yearly check-up while taking Lo Loestrin Fe so your gynecologist can make sure it’s still safe for you. They might check your blood pressure, do a breast or cervical exam, and order blood tests if needed.

                    faqs

                    Frequently asked questions about Lo Loestrin Fe

                    Does Lo Loestrin Fe cause weight gain?
                    It can. Some people who took Lo Loestrin Fe noticed changes in their weight. But this is often due to bloating or holding extra water, not actual fat gain. If you’re worried about weight changes while taking this medication, talk to your gynecologist.
                    How effective is Lo Loestrin Fe?
                    In clinical studies, Lo Loestrin Fe prevented pregnancy about 97% of the time. The medication works best when you take it every day at the same time. But if you miss doses or take it at different times each day, it might not work as well in preventing pregnancy. Talk with your gynecologist to determine the best birth control option for you.
                    Is Lo Loestrin Fe a combination pill?
                    Yes, Lo Loestrin Fe is a combination oral contraceptive (COC) that contains two hormones: a progestin called norethindrone and an estrogen called ethinyl estradiol. It's a type of biphasic birth control, meaning the hormone levels change during the month. Each pack has 24 blue tablets with 1 mg norethindrone and 10 mcg ethinyl estradiol, followed by 2 white tablets with only 10 mcg ethinyl estradiol. The final 2 brown tablets are placebo pills that contain ferrous fumarate, an iron supplement.
                    How do you take Lo Loestrin Fe?
                    It's recommended that you start taking Lo Loestrin Fe on Day 1 of your period — this means the first day you start bleeding. Take one blue tablet every day for 24 days, then one white tablet each day for the next 2 days, and finally one brown tablet each day for the last 2 days of the pack. If you don’t start the pills on the first day of your period, make sure to use a hormone-free birth control method for the first 7 days to help prevent pregnancy.
                    What are some long-term side effects of Lo Loestrin Fe?
                    Although rare, birth control pills like Lo Loestrin Fe can sometimes lead to long-term side effects like blood clots, stroke, heart attack, or certain types of cancers. If you're worried about these risks, it's a good idea to talk to your gynecologist. They can help you understand your options and choose what’s best for you.
                    What color pill do you get your period on Lo Loestrin Fe?
                    You'll usually get your period while taking the brown pills in Lo Loestrin Fe. These are the last 2 pills in the 28-day pack and contain iron (not hormones). In studies, most people on average had their period for less than 2 days each month.
                    Can you have no periods while taking Lo Loestrin Fe?
                    Yes, it's possible for you to have no periods while taking Lo Loestrin Fe. In a clinical study, some people had no period by the 1st month, and nearly half had no period by the 13th month. If you miss your period and didn't take your pills as directed, talk to your gynecologist to check for pregnancy.
                    How much estrogen is in Lo Loestrin Fe?
                    While most other combination birth control pills contain 30 to 50 mcg of ethinyl estradiol, Lo Loestrin Fe has only 10 mcg of ethinyl estradiol. This makes it one of the lowest-dose options available, which might be helpful if you're sensitive to estrogen-related side effects.

                    What are the risks and warnings for Lo Loestrin Fe?

                    Lo Loestrin Fe can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

                    risk-warning

                    Cigarette smoking and risk for blood clots

                    • Risk factors: Over 35 years old who smoke cigarettes

                      If you smoke cigarettes, using combined oral contraceptives (COCs), like Lo Loestrin Fe, raises your risk for blood clots. These blood clots can lead to more serious problems, such as heart attack and stroke. People aged 35 years and older who smoke are at even higher risk for these problems. If you smoke, talk with your gynecologist about safer birth control alternatives.

                      risk-warning

                      Blood clots and strokes

                      • Risk factors: Age 35 or older and smoke | Recent surgery with a long period of bed rest | Starting Lo Loestrin Fe less than a month after childbirth | High blood pressure | People identified as obese | High cholesterol | Diabetes | Higher dose of estrogen

                        Lo Loestrin Fe raises your risk of blood clots. These clots can occur anywhere in your body, including your lungs (pulmonary embolism or PE), legs (deep vein thrombosis or DVT), brain (stroke), and heart (heart attack). Get emergency help right away if you have any signs of a blood clot.

                        • Brain: weakness or numbness in your arms, legs, or face on one side of the body, trouble speaking, blurred vision, dizziness, loss of balance, trouble walking, or confusion

                          • Eyes: trouble seeing, bulging eye, double vision

                            • Heart: chest pain, sweating, nausea, or dizziness

                              • Lungs: trouble breathing, chest pain, or cough

                                • Legs: cramps, swelling, pain, or muscle tightness

                                  If you need to have surgery, tell your care team you're taking Lo Loestrin Fe. They might have you stop taking it 4 weeks before until 2 weeks after your surgery to lower your risk of blood clots. If you recently delivered a baby, you shouldn't start Lo Loestrin Fe until 4 weeks after delivery if you're not breastfeeding your child.

                                  risk-warning

                                  Liver problems

                                  • Risk factors: History of liver problems | Taking Lo Loestrin Fe long term | Taking certain hepatitis C combination medications

                                    Don't take Lo Loestrin Fe if you have liver problems. Although rare, COCs like Lo Loestrin Fe can raise your risk of benign liver tumors. Signs of liver problems can include jaundice (yellowing of the skin or eyes), along with fever, tiredness, loss of appetite, or dark colored urine.

                                    risk-warning

                                    High blood pressure

                                    • Risk factors: Older age | Taking COCs for a long time

                                      Lo Loestrin Fe can raise your blood pressure, so you might want to check your blood pressure while you're taking this medication. The risk is higher in older adults that have taken birth control for a long time. Stop taking Lo Loestrin Fe and let your care team know if your blood pressure is unusually high.

                                      risk-warning

                                      High blood sugar and triglycerides

                                      • Risk factors: Prediabetes or diabetes | History of high triglycerides

                                        Lo Loestrin Fe can raise your blood sugar and triglyceride (fat) levels. If you have diabetes or prediabetes, let your prescriber know if you experience any changes in your blood sugar. A rise in triglycerides can lead to serious conditions like inflammation of the pancreas (pancreatitis). Get emergency medical help if you notice symptoms of pancreatitis, which can include stomach pain, nausea, or vomiting.

                                        risk-warning

                                        Headache

                                        Let your prescriber know if you experience new or worsening migraines or headaches while taking Lo Loestrin Fe. You'll have to stop this medication if your migraine or headache doesn't go away or becomes severe.

                                        risk-warning

                                        Irregular bleeding

                                        People who take Lo Loestrin Fe can sometimes experience breakthrough bleeding and spotting, especially in the first 3 months. This bleeding can be light or feel like a regular period. Keep taking your pills as directed, and let your gynecologist know if the bleeding bothers you.

                                        You might also stop getting your period while using Lo Loestrin Fe. If you missed doses or started your pack late and don’t get your period, there’s a chance you could be pregnant. If you’ve taken your pills correctly and miss two periods in a row, talk to your gynecologist or take a pregnancy test to be safe.

                                        risk-warning

                                        Depression

                                        Talk to your gynecologist if you experience symptoms of depression or worsening depression while taking Lo Loestrin Fe. They might consider stopping this medication if you have serious depression.

                                        risk-warning

                                        Risk for breast and cervical cancer

                                        • Risk factors: History of breast or cervical cancer | Taking COCs for a long time

                                          Study results are mixed, but there's a possibility that Lo Loestrin Fe and other COCs can raise your risk for breast and cervical cancer.

                                          Don't take Lo Loestrin Fe if you currently have or have had breast cancer because some types of breast cancer grow faster in the presence of estrogen, an ingredient in this medication. You can perform breast self-checks regularly at home and get yearly breast exams with your gynecologist to help with early breast cancer detection. Let them know if you notice any new or abnormal lumps, pain, or swelling in your breasts.

                                          Make sure you follow up with your gynecologist to get proper screenings for cervical cancer. Report any signs of vaginal bleeding or discharge that's not normal.

                                          risk-warning

                                          Worsening of other health conditions

                                          • Risk factors: History of hereditary angioedema | History of chloasma gravidarum

                                            If you have certain conditions, such as hereditary angioedema or chloasma (a skin condition that causes dark patches on the face), talk to your gynecologist before taking Lo Loestrin Fe because it might worsen your symptoms. If you have a history of chloasma, limit exposure to the sun or UV light while taking birth control pills like Lo Loestrin Fe.
