How Low-Ogestrel works
Low-Ogestrel is a combination oral contraceptive (COC) that contains two hormones: ethinyl estradiol (an estrogen) and norgestrel (a progestin). These two hormones work together to help prevent pregnancy by:
Stopping ovulation (release of an egg from the ovary)
Changing cervical mucus to block sperm movement
Creating an unfriendly environment for the fertilized egg by changing the lining in the uterus (womb)

Pharmacist tips for Low-Ogestrel
Before starting Low-Ogestrel, discuss your full medical history with your OB-GYN provider. This medication can worsen certain conditions. Some examples are chloasma (a condition that causes dark skin patches) and hereditary angioedema (episodes of severe swelling in your body). If you have a history of chloasma, avoid sun exposure while taking Low-Ogestrel.
Set an alarm to help you remember to take Low-Ogestrel at the same time every day. Forgetting to take your pill raises the chance of getting pregnant. If you miss a dose, refer to the instructions or call your healthcare professional (HCP).
It's normal to have spotting (light vaginal bleeding outside of your period) or feel sick to your stomach for the first few packs of Low-Ogestrel. This should get better over time, but if it doesn't contact your HCP.
You'll typically get your period within 3 days after you finish the 21 active tablets in your Low-Ogestrel pack. During this time, you'll be taking the 7 placebo tablets. Make sure to start a new Low-Ogestrel pack on the day after you finish your placebo tablets, even if you're still bleeding.
If you have vomiting or diarrhea, or take certain medications, Low-Ogestrel might not work as well for you. Always use a back-up birth control method until you're able to check with your HCP.
Any time you vomit within 3-4 hours of taking Low-Ogestrel, it's considered a missed dose and you should refer to the instructions for missed doses that came with your prescription or ask your pharmacist or HCP.
If you've been taking Low-Ogestrel as instructed and have missed two periods in a row or feel like you might be pregnant, call your HCP. Studies haven't shown a risk of birth defects in females who've used birth control pills before pregnancy or during early pregnancy, but it's no longer necessary to take them once you're pregnant.
Oral contraceptives like Low-Ogestrel can lower the amount of breast milk you're able to produce while breastfeeding. If you're breastfeeding, ask your HCP about alternative birth control options.
Frequently asked questions about Low-Ogestrel

What are the risks and warnings for Low-Ogestrel?
Low-Ogestrel 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.
Cigarette smoking and serious heart problems
Risk factors: Females over 35 years old who smoke cigarettes
If you smoke cigarettes, taking combined oral contraceptives (COCs) like Low-Ogestrel raises your risk for serious health problems, such as stroke, heart attack, and blood clots. Females ages 35 years and older who smoke are at even higher risk for these problems. If you smoke, talk with your OB-GYN provider or healthcare professional (HCP) about safer birth control alternatives.
Blood clots and strokes
Risk factors: Females over 35 years old who smoke | Females over 40 years old who don't smoke | Recent surgery with a long period of bed rest | Starting Low-Ogestrel less than a month after childbirth | High blood pressure | People identified as obese | High cholesterol | Diabetes | Higher dose of estrogen
Low-Ogestrel 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 healthcare team you're taking Low-Ogestrel. They might have you stop taking it 4 weeks before until 2 weeks after your surgery to lower your risk of blood clots.
Risk of breast and cervical cancer
Risk factors: History of breast cancer | Taking COCs for a long time
Study results are mixed, but there's a possibility that Low-Ogestrel and other COCs can raise your risk for breast and cervical cancer.
Don't use Low-Ogestrel if you have breast cancer because some types of breast cancer grow faster in the presence of estrogen, an ingredient in this birth control pill. To help with early breast cancer detection, you can do monthly breast self-checks at home and yearly breast exams with your healthcare professional. Call your HCP if you notice any abnormal changes or feel lumps, pain, or swelling in your breasts.
Get medical help right away if you experience abnormal vaginal bleeding, discharge, or pain during sex, since these could be signs of cervical cancer.
Liver problems
Risk factors: Liver problems or infection in the liver | Taking COCs with 50 mcg of estrogen or higher
Though rare, Low-Ogestrel can cause liver problems, such as liver damage and liver tumors. These problems are linked more with earlier formulations of COCs that contained higher doses of estrogen (50 mcg or higher), and less so with Low-Ogestrel since it only contains 30 mcg of estrogen. Don't use this medication if you already have liver problems. Call your HCP right away if you experience symptoms of liver problems, such as tiredness, stomach pain, or yellowing of the skin or whites of the eyes.
High blood sugar and triglycerides
Risk factors: Prediabetes or diabetes | Personal or family history of high triglycerides | High dose
COCs like Low-Ogestrel might raise your blood sugar and triglyceride (fat) levels. If you have diabetes, let your HCP know if you experience any changes in your blood sugar. Make sure to go to all of your check-ups so your healthcare team can monitor any changes.
High blood pressure
Risk factors: High blood pressure | Older age | Using COCs for a long time | Kidney problems
Low-Ogestrel and other COCs can raise your blood pressure. Your HCP might ask you to check your blood pressure regularly. If you notice your blood pressure is higher while you're taking this medication, contact your HCP. If you have uncontrolled high blood pressure, Low-Ogestrel might not be the best option for you.
Headache
Headaches are a common side effect of COCs like Low-Ogestrel. But, if you experience a new migraine, a migraine that's worse than normal, or a new headache that keeps coming back or is severe, call your HCP so you can be checked out.
Irregular bleeding
Breakthrough bleeding and spotting are common side effects of hormonal birth control pills. This is more common during the first 3 months of using Low-Ogestrel. Let your HCP know if you experience any vaginal bleeding outside of your period, or if your period has stopped completely. There are other causes besides your birth control pills for irregular bleeding that your HCP will evaluate.
Depression
Risk factors: History of depression
Let your HCP know if you experience symptoms of depression or worsening depression while taking Low-Ogestrel. In cases of serious depression, your OB-GYN provider or HCP might have you stop taking it.
Gallbladder problems
Some studies suggest that Low-Ogestrel can raise the risk of gallbladder disease since more progestin and estrogen can lead to higher chance of gallstones. Although the risk is low, talk to your gynecologist if you a history of gallbladder disease before starting Low-Ogestrel.
Interactions with other medications
Certain medications can make Low-Ogestrel get broken down faster in your body, making it less effective. And this can lead to pregnancy. Some examples include carbamazepine (Tegretol) and phenytoin (Dilantin). Use a back-up method or other form of birth control for at least 28 days after stopping any of these medications. Other medications can raise the amount of Low-Ogestrel in your body, which can lead to more side effects. Make sure to tell your HCP or pharmacist all of your medications so they can make sure they don't interact with Low-Ogestrel.
If you're taking medications to treat hepatitis C, immediately let your HCP know that you're taking a COC. Certain hepatitis C medications can affect the level of Low-Ogestrel in your body, either making it work not as well in preventing pregnancy or raising your risk of side effects. Your healthcare team can give you instructions about what to do if you're taking a hepatitis C medication that can interact with Low-Ogestrel.
