Zafemy (norelgestromin / ethinyl estradiol) is a birth control patch you apply to your skin once a week. It contains two hormones (estrogen and progesterone) that work together to prevent pregnancy. If you use it perfectly, it's 99% effective. You can place the patch on your upper arm, stomach, buttock, or back. But if you weigh more than 198 pounds or have a body mass index or BMI of 30 kg/m² or higher, it might not work as well. Some people might experience side effects like sore breasts, headaches, or a rash at the application site.
Zafemy (norelgestromin / ethinyl estradiol) is a combination of two hormones: norelgestromin (a progestin) and ethinyl estradiol (an estrogen). These two hormones work together to help prevent pregnancy by:

In clinical studies, about 3% of people reported weight gain while using Zafemy. But it's not clear if the birth control was the cause. In general, studies show that hormonal contraceptives aren't likely to cause weight gain. If you do gain some weight, it's more likely to due your body holding onto extra water, rather than added body fat. Talk with your prescriber if you're concerned about Zafemy and weight gain.
Apply Zafemy on your upper outer arm, stomach, buttock, or back. Don't put the patch where it might rub off, like the waistline. Also, don't place it on cuts, sores, or irritated skin since this could affect how much medication your body absorbs.
Zafemy and Xulane are both branded generic birth control patches of Ortho Evra, which is no longer available. Both contain the same hormones (norelgestromin and ethinyl estradiol) and are applied once a week to prevent pregnancy. The main difference is that Xulane has a larger patch size (14 cm²) compared to Zafemy (12.5 cm²). Both patches are over 90% effective when used correctly. Talk to your prescriber if you have questions about comparing these medications.
While using Zafemy, you might notice your period becoming lighter or stopping completely. This happens because Zafemy changes your hormonal levels, which stops ovulation and prevents pregnancy. You’ll apply a new patch once a week for 3 weeks, then leave week 4 patch-free. During this time, you might have withdrawal bleeding (similar to a period). Don't use the patch continuously to skip your period unless your healthcare team says it’s safe.
When used perfectly, Zafemy is 99% effective at preventing pregnancy. But it might not work as well if you weigh more than 198 pounds or have a body mass index (BMI) of 30 kg/m² or higher.
How fast Zafemy starts working depends on when you apply your first patch. If you start on the Sunday after your period begins, use a hormone-free backup birth control (like condoms) for the first week to stay protected. If you start the patch on the first day of your period, you won't need backup birth control. Talk to your prescriber about the best time to start this medication.
To use Zafemy, open the foil pouch and peel off half of the clear plastic from the sticky side. Place the sticky side on clean, dry skin and then peel off the other half of the plastic. Press firmly on the patch for 10 seconds to make sure it sticks completely.
Zafemy (norelgestromin / ethinyl estradiol) 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.
Smoking cigarettes while using Zafemy (norelgestromin / ethinyl estradiol) can significantly raise your risk for blood clots. These blood clots can lead to more serious problems, such as heart attack and stroke. The risk is greater if you're over 35 years old and have a history of smoking cigarettes. If you smoke, talk with your gynecologist about safer birth control alternatives.
Compared to other combined hormonal contraceptives, Zafemy (norelgestromin / ethinyl estradiol) leads to higher estrogen absorption, which might raise the risk of side effects, including serious 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.
If you need to have surgery, tell your care team you're taking Zafemy (norelgestromin / ethinyl estradiol). 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 Zafemy (norelgestromin / ethinyl estradiol) until 4 weeks after delivery if you're not breastfeeding your child.
Don't use Zafemy (norelgestromin / ethinyl estradiol) if you have liver problems, such as hepatitis, severe cirrhosis, or liver tumors. Although rare, this medication can raise your risk of benign liver tumors. If you notice signs of liver problems, stop using Zafemy (norelgestromin / ethinyl estradiol) and talk to your gynecologist about other birth control options. Signs of liver problems include jaundice (yellowing of the skin or whites of the eyes), fever, tiredness, loss of appetite, or dark urine.
Zafemy (norelgestromin / ethinyl estradiol) can raise your blood pressure. The risk is higher if you're older and have been using birth control for a long time. If you have a history of high blood pressure that's well-controlled, your prescriber might monitor you while you use Zafemy (norelgestromin / ethinyl estradiol). If you have concerns, talk with them about the risks and benefits of using this medication.
Some studies show that Zafemy (norelgestromin / ethinyl estradiol) can slightly raise your risk of gallbladder problems. And if you already have gallbladder problems, this medication could make them worse. If you’ve had cholestasis (a liver condition that slows or stops bile flow) from birth control or pregnancy before, you might have a higher risk of getting it again with Zafemy (norelgestromin / ethinyl estradiol). Talk to your prescriber if you have a history of gallbladder or liver problems before using this medication.
Zafemy (norelgestromin / ethinyl estradiol) can raise your blood sugar and triglycerides levels. If you have prediabetes or diabetes, your prescriber will likely monitor your blood sugar while you take this medication. High triglycerides can lead to a higher risk of pancreatitis (inflammation of the pancreas). Speak with your gynecologist before starting Zafemy (norelgestromin / ethinyl estradiol) if you have a history of high blood sugar or triglycerides. They might suggest a different birth control option or monitor your lab work more closely while you're using this medication.
Let your gynecologist know if you experience new or worsening migraines or headaches while using Zafemy (norelgestromin / ethinyl estradiol). If you develop frequent, severe, or new headaches, you might need to stop the medication.
People who use Zafemy (norelgestromin / ethinyl estradiol) can sometimes experience breakthrough bleeding or spotting. If this happens, talk to your gynecologist to rule out pregnancy, infections, or other medical conditions. If no serious cause is found, the bleeding might stop over time or after switching to a different birth control.
In clinical trials, most people started their withdrawal bleeding on the fourth day of the patch-free week, lasting about 5 to 6 days. If you have concerns about irregular bleeding, talk to your gynecologist.
If you have a history of depression, your prescriber will monitor you while using Zafemy (norelgestromin / ethinyl estradiol). If your depression gets worse or becomes serious, they might stop the medication. Let your prescriber know if you experience mood changes, sadness, or loss of interest in activities while taking this medication.
Study results are mixed, but Zafemy (norelgestromin / ethinyl estradiol) and other combined hormonal birth control pills might raise your risk for breast and cervical cancer.
Don't take Zafemy (norelgestromin / ethinyl estradiol) if you currently have or have had breast cancer because some types of breast cancer grow faster in the presence of estrogen, which is in this medication. Perform breast self-checks regularly at home and get yearly breast exams with your gynecologist to help with early 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.
If you have certain conditions, such as hereditary angioedema or chloasma (a skin condition that causes dark patches on the face), talk to your prescriber before taking Zafemy (norelgestromin / ethinyl estradiol) because it might worsen your symptoms. If you have a history of chloasma, limit exposure to the sun or UV light while taking Zafemy (norelgestromin / ethinyl estradiol).
