Please read this PATIENT INFORMATION before you start taking Jinteli™ (norethindrone acetate and ethinyl estradiol tablets, USP) and each time you refill Jinteli tablets. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

What is the mos t important information I s hould know about Jinteli™ (norethindrone acetate and ethinyl estradiol tablets, USP) (a combination of estrogen and progestin hormones)?

  • Do not use estrogens and progestins to prevent heart disease, heart attacks, strokes or dementia.

Using estrogens and progestins may increase your chances of getting heart attack, strokes, breast cancer, and blood clots. Using estrogens, with or without progestins may increase your risk of dementia, based on a study of women age 65 years or older. It is unknown whether this study applies to women who began estrogen and progestin therapy before age 65. You and your healthcare provider should talk regularly about whether you still need treatment with Norethindrone Acetate and Ethinyl Estradiol Tablets.

What is Jinteli?

Jinteli is medicine that contains two kinds of hormones, an estrogen and a progestin.

What is Jinteli used for?

Jinteli is used after menopause to:

  • reduce moderate to severe hot flushes
    Estrogens are hormones made by a woman's ovaries. The ovaries normally stop making estrogens when a woman is between 45 to 55 years old. This drop in body estrogen levels causes the “change of life” or menopause, the end of monthly menstrual periods. Sometimes both ovaries are removed during an operation before natural menopause takes place. The sudden drop in estrogen levels causes “surgical menopause.”
    When estrogen levels begin dropping, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden intense episodes of heat and sweating (“hot flashes” or “hot flushes”). In some women the symptoms are mild; in others they can be severe. You and your healthcare provider should talk regularly about whether you still need treatment with Jinteli.
  • help reduce your chances of getting osteoporos is (thin, weak bones )
    Osteoporosis from menopause is a thinning of the bones that makes them weaker and easier to break. If you use norethindrone acetate and ethinyl estradiol tablets only to prevent osteoporosis from menopause, talk with your healthcare provider about whether a different treatment or medicine without estrogens might be better for you. You and your healthcare provider should talk regularly about whether you should continue with Jinteli.
    Weight-bearing exercise, like walking or running, and taking calcium and vitamin D supplements may also lower your chances of getting postmenopausal osteoporosis. It is important to talk about exercise and supplements with your healthcare provider before starting them.

Who should not take Jinteli?

Do not take Jinteli if you have had your uterus removed (hysterectomy).

Jinteli tablets contain a progestin to decrease the chances of getting cancer of the uterus. If you do not have a uterus, you do not need a progestin and you should not take Jinteli.

Do not start taking Jinteli if you:

  • currently have or have had certain cancers. Estrogens may increase the chances of getting certain types of cancers, including cancer of the breast and uterus. If you have or had cancer, talk with your healthcare provider about whether you should take Jinteli.
  • had a stroke or heart attack in the past year.
  • currently have or have had blood clots.
  • currently have or have had liver problems .
  • are allergic to Jinteli or any of its ingredients . See the end of this leaflet for a list of ingredients in Jinteli.
  • think you may be pregnant. If you think you may be pregnant, do not take Jinteli.

Tell your healthcare provider:

  • if you are breast-feeding. The hormones in Jinteli can pass into your milk.
  • about all of your medical problems . Your healthcare provider may need to check you more carefully if you have certain conditions, such as asthma (wheezing), epilepsy (seizures), migraine, endometriosis, lupus, problems with your heart, liver, thyroid, kidneys, or have high calcium levels in your blood.
  • about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements. Some medicines may affect how Jinteli works. Jinteli may also affect how your other medicines work.
  • if you are going to have surgery or will be on bed rest. You may need to stop taking estrogens and progestins.

How should I take Jinteli?

Take your Jinteli pill once a day at about the same time each day. If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and go back to your normal schedule. Do not take two doses at the same time.

Start at the lowest dose and talk to your healthcare provider about how well that dose is working for you.

Estrogens should only be used as long as needed. You and your healthcare provider should reevaluate every 3 to 6 months whether or not you still need treatment with Jinteli.
