It is very important that your doctor check your progress at regular visits. This will allow your doctor to make sure that this medicine is working properly and to check you for any problems or unwanted effects that may be caused by this medicine.

Do not use this medicine if you have used an MAO inhibitor (MAOI) (eg, isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]) within the past 14 days.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

This medicine may cause sleep-related breathing problems (eg, sleep apnea, sleep-related hypoxemia). Your doctor may decrease your dose if you have sleep apnea (stop breathing for short periods during sleep) while using this medicine.

Using too much nasal fentanyl, or taking too much of another opioid while using nasal fentanyl, may cause an overdose. If this occurs, get emergency help right away. Your healthcare provider may prescribe naloxone to treat an overdose. Naloxone is a medicine that can temporarily reverse the effects of an overdose. If you have been prescribed naloxone, or purchased it over-the-counter, make sure your household members know how to use it in the event of an overdose. Emergency help is still needed after naloxone is used because the reversal effects are only temporary. Symptoms of an overdose include: drowsiness, extreme dizziness or weakness, irregular, fast or slow, or shallow breathing, pale or blue lips, fingernails, or skin, pinpoint pupils, relaxed and calm, slow heartbeat or breathing, seizures, sleepiness, trouble breathing, or cold, clammy skin. Tell your doctor right away if you notice these symptoms. Your doctor may also give naloxone to treat an overdose.

Using this medicine while you are pregnant may cause neonatal withdrawal syndrome in your newborn baby. Tell your doctor right away if your baby has an abnormal sleep pattern, diarrhea, a high-pitched cry, irritability, shakiness or tremors, weight loss, vomiting, or fails to gain weight.

Fentanyl is a medicine that can harm or cause death to a child. Patients and caregivers should keep this medicine out of the reach of children. Carefully dispose of any partially used units or unused medicine properly.

This medicine will add to the effects of alcohol and other central nervous system (CNS) depressants. This effect may last for a few days after you stop using this medicine. CNS depressants are medicines that slow down the nervous system, which may cause drowsiness or make you less alert. Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds, sedatives, tranquilizers, benzodiazepines, sleeping medicines, other prescription pain medicine or opioids, barbiturates or seizure medicine, muscle relaxants, or anesthetics (numbing medicines), including some dental anesthetics. Check with your doctor before taking any of the other medicines listed above while you are using this medicine.

Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.

Check with your doctor right away if you have darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting. These may be symptoms of adrenal gland problems.

Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve the dizziness or lightheadedness.

Fentanyl may cause some people to become drowsy, dizzy, or lightheaded, or to feel a false sense of well-being. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert and clearheaded.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Using opioids for a long time may cause severe constipation. To prevent this, your doctor may tell you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.

Using too much of this medicine may cause reduced infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
