Duragesic

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe to continue using Duragesic.

• More common side effects may include:
  Abdominal pain, anxiety, confusion, constipation, depression, diarrhea, dizziness, dry mouth, exaggerated high spirits, hallucinations, headache, impaired or interrupted breathing, indigestion, itching, loss of appetite, nausea, nervousness, shortness of breath, sleepiness, sweating, urinary retention, vomiting, weakness

Why should Duragesic not be prescribed?

Duragesic should never be used in situations where the right dosage hasn't been established in advance--for instance, after an operation or an accident. It should not be used for mild or intermittent pain that responds to other painkillers.

Duragesic should not be given to children under 2 years old or children who are not tolerant to narcotic painkillers.

The drug should also be avoided if it causes an allergic reaction.

Special warnings about Duragesic

Heat can increase the release of fentanyl from the Duragesic patch, thereby increasing the risk of impaired breathing and other side effects. Do not expose the patch to heating pads, electric blankets, heated water beds, heat lamps, saunas, hot tubs, or other external sources of heat. Alert your doctor if you develop a high fever (104 degrees Fahrenheit or more).

Like other narcotic painkillers, Duragesic can impair your reactions. Do not drive or operate dangerous machinery until you are certain you can tolerate the drug.

Extended use of Duragesic can lead to physical and psychological dependence, but may be necessary to control chronic pain. Your doctor will take this into account when prescribing this drug.

If your breathing is already impaired by chronic pulmonary disease, Duragesic's tendency to reduce respiration can be especially dangerous. The doctor will determine your dosage with extra caution.

Duragesic is not recommended for people with head injuries and other conditions that increase pressure on the brain, or for those who are semi-conscious or in a coma. It should be used with caution by people with brain tumors.
