However, check with your doctor if drowsiness that is severe enough to interfere with your activities continues for more than a few days. After you have been using this medicine for awhile, “breakthrough” pain may occur more often than usual, and it may not be relieved by your regular dose of medicine. If this occurs, do not increase the amount of fentanyl skin patch or other opioid that you are using without first checking with your doctor.

Discontinue all other extended-release opioids when beginning therapy. When prescribing, do not convert patients on a mcg per mcg basis from any other fentanyl products. Using too much of this medicine may cause infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.

Some examples are street drugs such as MDMA/ “ecstasy,” St. John’s wort, certain antidepressants (such as SSRIs like fluoxetine/paroxetine, SNRIs like duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs. Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Keep this medicine in a safe place to prevent theft, misuse, or abuse. This medication is not recommended for use by children younger than 2 years.

Sometimes, individuals mix it with other drugs because of its potency. For continuous delivery, a transdermal patch can slowly deliver fentanyl through the skin and into the bloodstream for up to 72 hours. As with other opioid drugs, fentanyl binds to the receptors in how long does fentanyl stay in your system the brain that affect pain and emotion. This causes feelings of well-being (euphoria) and relaxation and relieves pain. Do not change to another form of fentanyl eg injection, skin patch, dissolving film, or “lollipop” device. If you switch from another form of fentanyl, you will not use the same dose.

• When used as a sedative, drug administration is most commonly via a drip.
• Fentanyl belongs to the group of medicines called opioid analgesics.
• That is, in combination with certain neuroleptic medications as part of therapeutic neuroleptanalgesia.
• Talk to your doctor about how well the medication is working and whether you are experiencing any side effects so that your doctor can decide whether your dose should be adjusted.
• It is only used in patients who are already taking opioid analgesics.

Alcohol interaction warning

• Fentanyl comes as a lozenge on a handle, a sublingual (underneath the tongue) tablet, and a buccal (between the gum and cheek) tablet to dissolve in the mouth.
• As the dosage increases, so does the risk of side effects.
• If they’re more severe or don’t go away, talk to your doctor or pharmacist.
• If you switch to fentanyl nasal spray from another form of fentanyl, you will not use the same dose.
• Discontinue all other extended-release opioids when beginning therapy.

A nurse or other trained health professional will give you this medicine after surgery. You will be taught how to use this medicine in the hospital, but the patch will be removed by your healthcare provider before you leave the hospital. Do not leave the hospital with the patch on your skin. It is very important that you understand the rules of the Opioid Analgesic REMS program to prevent addiction, abuse, and misuse of fentanyl. To prevent accidental fentanyl overdoses, you can use fentanyl test strips to ensure other drugs don’t contain the opioid.

However, be careful to wash and dry the area around the patch gently. If this does occur, throw away the patch and apply a new one in a different place. Make sure the area is completely dry before applying the new patch. Your healthcare provider will dispose of the Ionsys® patch after removing it.

Place the sticky side of the used patch on the disposal unit and seal the entire package. If the patch has not been used, take it out of the pouch and remove the liner that covers the sticky side before placing it on the disposal unit. Talk to your pharmacist if you have questions about how to use the disposal unit. Do not flush the pouch or the protective liner down the toilet. Ask your healthcare professional how you should dispose of any medicine you do not use.

Illegal fentanyl, however, has an unknown amount of fentanyl and may be mixed with other drugs, which may result in harmful behaviors. Some people claim they can tell they are taking fentanyl, rather than heroin, due to its pale color (which ranges from bright white to off-white) and sweet taste. However, this is not a reliable indicator of whether a person is taking real fentanyl or not. Fentanyl use can result in death even with one dose, especially if a person accidentally takes it incorrectly. People who take fentanyl may develop a tolerance to high doses, meaning that more of the drug is needed to achieve the desired effect.

How do I dispose of medicines safely?

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 still contains enough fentanyl to cause serious harm, even kill a child or pet, so fold it in half with the sticky sides together and discard properly. Do not let children see you apply a patch, and do not apply the patch where children can see it. Children have found patches that have fallen off or removed patches on sleeping adults and put them in their mouths or on their bodies with fatal results.
