fentanyl

If you leave a patch on for more than 3 days (72 hours), remove the patch and apply a new patch as soon as you remember. Do not double the dose to catch up.

Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. Learn how to properly use, store, and discard the patches. If you have any questions, ask your doctor or pharmacist. Before you start using this medication, ask your doctor or pharmacist if you should stop or change the dose of your other narcotic medication(s). It may take up to 24 hours before you have pain relief from fentanyl patches. For added pain relief, your doctor may direct you to also take quick-acting narcotic or non-narcotic pain medications (such as acetaminophen, ibuprofen). Ask your doctor or pharmacist if you have any questions about using fentanyl safely with other drugs. Apply this medication to the skin as directed by your doctor. Do not apply on burns, cuts, irritated skin, or skin that has been exposed to radiation (x-ray treatment). Select a dry, non-hairy area on a flat part of your body, such as the chest, sides, back, or upper arms. In young children or in people unable to think clearly (such as due to dementia), apply the patch on the upper back to lessen the chance it might be removed or placed in the mouth. If there is hair on the skin, use scissors to clip the hair as close as possible to the skin. Do not shave hair since this might cause skin irritation. If needed, use water to clean the area. Do not use soap, oils, lotions, or alcohol on the application site. Dry the skin well before applying the patch. The patch is usually changed every 72 hours. To avoid irritation, apply to a different area each time. Be sure to remove the old patch before applying a new patch. The used patch should be folded in half with the sticky sides together and properly discarded. Do not use the patch if it appears to be broken, cut, or damaged. Remove from the sealed pouch, peel off the protective liner, and apply immediately to the skin. Press firmly in place with the palm of the hand for 30 seconds, making sure the contact is complete (especially around the edges). If your prescribed dose is for more than one patch, make sure the edges of the patches do not touch or overlap. After applying the patch, wash your hands with water only. If you have problems with the patch not sticking at the application site, you may tape the edges in place with first aid tape. If this problem persists, ask your doctor for advice. If the patch falls off before 72 hours, a new patch may be applied to a different skin site. Be sure to let your doctor know if this happens. If you accidentally touch the sticky layer to your skin or handle a cut or damaged patch, wash the area well with clear water. If the patch comes off and accidentally sticks to the skin of another person, immediately remove the patch, wash the area with water, and get medical help for them right away. Do not use soap, alcohol, or other products to wash the area. The dosage is based on your medical condition and response to treatment. Do not apply more patches than directed, change them more frequently, or use them for a longer time than prescribed. This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as restlessness, watering eyes, runny nose, nausea, sweating, muscle aches) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Ask your doctor or pharmacist for more details, and report any withdrawal reactions immediately. When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well. Along with its benefits, this medication may rarely cause abnormal drug-seeking behavior (addiction). This risk may be increased if you have abused alcohol or drugs in the past. Take this medication exactly as prescribed to lessen the risk of addiction. Tell your doctor if your pain persists or worsens.

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: certain pain medications (mixed narcotic agonist-antagonists such as pentazocine, nalbuphine, butorphanol), narcotic antagonists (such as naltrexone), sibutramine. Other medications can affect the removal of fentanyl from your body, which may affect how fentanyl works. Examples include cimetidine, nefazodone, St. John's wort, azole antifungals including itraconazole/ ketoconazole, calcium channel blockers such as diltiazem/verapamil, HIV drugs such as nelfinavir/ritonavir, macrolide antibiotics including erythromycin, rifamycins including rifampin, certain anti-seizure medicines including carbamazepine, among others. Avoid taking MAO inhibitors (isocarboxazid, linezolid, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine) within 2 weeks before, during, and after treatment with this medication. In some cases a serious (possibly fatal) drug interaction may occur. The risk of serious side effects (such as slow/shallow breathing, severe drowsiness/dizziness) may be increased if this medication is used with other products that may also affect breathing or cause drowsiness. Therefore, tell your doctor or pharmacist if you are taking other products such as alcohol, allergy or cough-and-cold products, anti-seizure drugs (such as phenobarbital), medicine for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants, other narcotic pain relievers (such as codeine), and psychiatric medicines (such as risperidone, amitriptyline, trazodone). Your medications or doses of your medications may need to be changed. 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.

Do not share this medication with others. It is against the law and the medication may cause harm to others. This medication has been prescribed for your current condition only. Do not use it later for another condition unless told to do so by your doctor. A different medication may be necessary in that case.

Older adults may be more sensitive to the effects of this drug, especially dizziness, drowsiness, or urinary problems. During pregnancy, this medication should be used only when clearly needed. Using it for long periods or in high doses near the expected delivery date is not recommended because of the potential for harm to the unborn baby. Discuss the risks and benefits with your doctor. Babies born to mothers who have used this medication for an extended time may have withdrawal symptoms such as irritability, abnormal/persistent crying, vomiting, or diarrhea. If you notice any of these symptoms in your newborn, tell the doctor promptly. This drug passes into breast milk and may rarely have undesirable effects on a nursing infant. Tell the doctor immediately if your baby develops unusual sleepiness, difficulty feeding, or trouble breathing. Consult your doctor before breast-feeding.

Nausea, vomiting, constipation, lightheadedness, dizziness, drowsiness, or headache may occur. Mild irritation, itching, or redness at the application site may also occur. Some of these side effects may decrease after you have been using this medication for a while. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. To prevent constipation, eat a diet adequate in fiber, drink plenty of water, and exercise. Ask your pharmacist for help in selecting a laxative (such as a stimulant type with stool softener). To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Fentanyl has a high risk for abuse and severe, possibly fatal, breathing problems. Do not use transdermal patches unless you have been regularly taking moderate to large amounts of narcotic pain medication. Otherwise, it may cause overdose (even death). The risk for harm is higher if you take the wrong dose/strength, or if you take it along with other drugs that might also affect breathing. Get medical help right away if you notice unusual slow/shallow breathing. Do not use this medication to relieve mild or short-term pain (such as due to headache/migraine, dental/medical procedures, or surgeries that do not require you to stay in a hospital). This medication is not for occasional ("as needed") use. Since they are not taken the same way, different forms of fentanyl (including lozenges, buccal tablets, patches) do not have the same effects at equal strengths and should not be substituted for each other. Tell your doctor or pharmacist of all medications that you use, especially of drugs that can affect how fentanyl works (see also Drug Interactions section). Do not start, stop, or change the dosage of any medicines you are using without your doctor's approval. Carefully follow the specific directions for using fentanyl transdermal patches. Raising your skin/body temperature or using cut or damaged fentanyl patches may cause overdose. Avoid increasing your skin temperature at/near the application site by using products such as heating pads, electric blankets, hot tubs, heat or tanning lamps. Avoid taking hot baths and sunbathing. However, you may bathe, shower, or swim while wearing the patch. Keep this medicine in a safe place to prevent theft, misuse, or abuse. This medication is not recommended for use in children younger than 2 years. Some manufacturers recommend that this product should not be used in children younger than 18 years. If a child accidentally swallows this drug, get medical help right away.
