DRUG INTERACTIONS: The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur. Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring.

To help your doctor and pharmacist give you the best care, be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval.

Some products that may interact with this drug include: acetaminophen, aromatase inhibitors (e.g., anastrazole, exemestane), ascorbic acid (vitamin C), atorvastatin, azole antifungals (e.g., itraconazole, ketoconazole), certain benzodiazepines (e.g., diazepam, lorazepam, temazepam), clofibric acid, corticosteroids (e.g., prednisolone), cyclosporine, metoprolol, morphine, phenylbutazone, raloxifene, sodium tetradecyl sulfate, tamoxifen, theophylline, medication for low thyroid (hypothyroidism).

Some drugs may cause hormonal birth control to work less well by decreasing the amount of birth control hormones in your body. This effect can result in pregnancy. Examples include griseofulvin, modafinil, rifamycins (such as rifampin, rifabutin), St. John's wort, drugs used to treat seizures (such as barbiturates, carbamazepine, felbamate, phenytoin, primidone, topiramate), HIV drugs (such as nelfinavir, nevirapine, ritonavir), among others.

Tell your doctor when you start any new drug, and discuss if you should use additional reliable birth control. Also tell your doctor if you have any new spotting or breakthrough bleeding, because these may be signs that your birth control is not working well.

This medication can affect the results of certain lab tests (e.g., blood tests such as glucose, clotting factors, lipids, thyroid). Make sure laboratory personnel and all your doctors know you use this medication.

This document does not contain all possible drug interactions. Keep a list of all the products you use. Share this list with your doctor and pharmacist to lessen your risk for serious medication problems.

OVERDOSE: Overdose with this medication is highly unlikely. However, if overdose is suspected, remove the patch and contact your local poison control center or emergency room immediately.

MISSED DOSE: If the patch comes off or you forget to remove it at the proper time, consult the Patient Information Leaflet or your doctor or pharmacist to establish a new dosing schedule. You may need to use a back-up form of birth control (e.g., condoms or spermicide) to prevent pregnancy.

If you have trouble remembering to change your patch, or if the patch falls off repeatedly, contact your doctor to discuss switching to another form of birth control.
