Norelgestromin
 
What is Norelgestromin and why is it prescribed?
Norelgestromin is a contraceptive skin patch. It contains estrogen and progestin, the same hormones found in many birth control pills. Fertility depends on regular fluctuations in the levels of these hormones. Contraceptives such as Norelgestromin reduce fertility by eliminating the fluctuations. Once applied to the skin, the Norelgestromin patch releases a steady supply of estrogen and progestin through the skin and into the bloodstream. Cigarette smoking increases the risk of serious heart-related side effects in women who use hormonal contraceptives. This risk increases with heavy smoking (15 or more cigarettes per day) and with age. There is an especially significant increase in heart disease risk in women over 35 years old who smoke and use hormonal birth control. Therefore, women who use Norelgestromin are strongly advised not to smoke.

How should you take Norelgestromin?
Follow your doctors directions for taking Norelgestromin. You should use three separate Norelgestromin patches during each 4-week menstrual cycle. Wear one patch a week for the first 3 weeks, then spend the fourth week patch-free. Your menstrual period should start during the fourth week. If you miss a dose and your patch becomes loose or falls off for less than 1 day, try to stick it back on, or apply a new patch immediately. If it's been missing for more than 1 day, or you're not sure how long it's been off, there's a chance you could become pregnant and you should use a backup method of birth control. Check the Norelgestromin patient information for instructions. If you forget to change your patch at any time during the 4-week cycle, check the Norelgestromin patient information for instructions. Keep Norelgestromin patches in their protective pouches until you're ready to wear them. Store at room temperature. Do not store in the refrigerator or freezer. Used patches still contain some active hormones. Fold each patch so that it sticks to itself before throwing it away.

Are there any Norelgestromin side effects?
Norelgestromin side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible.

What are the possible food and drug interactions when taking Norelgestromin?
If Norelgestromin is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Be sure to inform your doctor of all the prescription and over the counter medications you are taking. It is especially important to check with your doctor before combining Norelgestromin with Acetaminophen (Tylenol), Antibiotics (such as ampicillin and rifampin), Anticonvulsants (such as Dilantin, Felbatol, Tegretol, Trileptal, and Topamax), Aspirin, Atorvastatin (Lipitor), Barbiturates (phenobarbital, Seconal), Clofibrate (Questran), Cyclosporine (Neoral, Sandimmune), Diabetes drugs (such as Glucotrol), Folic acid, Griseofulvin (Fulvicin, Grisactin), Itraconazole (Sporanox), Ketoconazole (Nizoral), Morphine (MS Contin), Phenylbutazone (Butazolidin), Prednisolone (Prelone, Pediapred), Protease inhibitors (HIV drugs such as Crixivan and Viracept), St. John's Wort, Temazepam (Restoril), Theophylline (Theo-Dur, Slo-bid), or Vitamin C. Remember, too, that hormonal contraceptives may affect tests for blood sugar levels and thyroid function and may cause an increase in blood triglyceride levels.

Are there any special warnings about Norelgestromin?
Hormonal contraceptives, including Norelgestromin, should be used with caution if you are over 40 years old; smoke tobacco; have liver, heart, gallbladder, or kidney disease; have high blood pressure, high cholesterol, diabetes, or epilepsy; or tend to be seriously overweight. Caution is also advised if you have blood circulation problems or have had a heart attack or stroke in the past. Be cautious, too, if you have problems with depression, migraine or other headaches, irregular menstrual periods, or visual disturbances. There have been conflicting reports on whether using hormonal contraceptives increases the risk of breast cancer. It appears that using hormonal contraceptives may slightly increase the chance of breast cancer, particularly if they're used before age 20. After hormonal contraceptives are stopped, the risk begins to go back down. If you use Norelgestromin, you should examine your breasts monthly and have yearly breast exams by a doctor. Also tell your doctor if you have a family history of breast cancer or if you have had breast nodules, fibrocystic breast disease, or an abnormal mammogram. You should also be aware that some experts think hormonal contraceptives may increase the risk of cervical cancer. This remains controversial, however. Many doctors think other factors are to blame. Since the blood's clotting ability may be affected by hormonal contraceptives, your doctor may take you off Norelgestromin prior to surgery or during a period of prolonged bed rest. You should wait at least 4 weeks after having a baby before starting Norelgestromin; and if you're breastfeeding, wait until the child is weaned before starting the drug. If you are recovering from a second trimester miscarriage or abortion, talk to your doctor before using Norelgestromin. If you develop a migraine or severe headache that does not let up or keeps recurring while you are taking Norelgestromin, check with your doctor. You may need to switch to a different form of birth control. You should also be aware that hormonal contraceptives have been know to cause rare cases of noncancerous, but dangerous, liver tumors. In people prone to high cholesterol and similar problems, hormonal contraceptives have been known to raise triglyceride levels, leading to pancreatitis. If you miss a menstrual period but have followed the Norelgestromin regimen correctly, contact your doctor but do not stop using the patches. If you miss a period and have not followed the regimen correctly, or if you miss two consecutive periods, you may be pregnant; stop using the patches and check with your doctor immediately to see if you are pregnant. Use another form of birth control while you're off the patch. Norelgestromin may be less effective in women who weigh more than 198 pounds; if you fall into this category, ask your doctor which form of birth control is best for you. Hormonal contraceptives do not protect against HIV infection (AIDS) or any other sexually transmitted disease. If there is a danger of infection, use a latex condom in addition to Norelgestromin. Be sure to tell the doctor that you are taking Norelgestromin before having lab tests done, since certain blood tests may be affected by hormonal contraceptives.
