What happens if I overdose Transtec 70µg/h?
Contact 1-800-222-1222 (the American Association of Poison Control Centers), your local, or emergency room immediately. Symptoms may include abnormal snoring; bluish skin or nails; cold and clammy skin; coma; difficult, shallow, or slow breathing; fainting; limp muscles; pinpoint or enlarged pupils; severe drowsiness, dizziness, or light-headedness; shortness of breath; slow or irregular heartbeat.
Proper storage of Transtec 70µg/h patch:
Store Transtec 70µg/h patch at 77 degrees F (25 degrees C). Brief storage at temperatures between 59 and 86 degrees F (15 and 30 degrees C) is permitted. Store in original packaging until just before use. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Transtec 70µg/h patch out of the reach of children and away from pets.
Overdose of Transtec 70µg/h in details
Clinical Presentation
Acute overdosage with Transtec 70µg/h transdermal system is manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen due to severe hypoxia in overdose situations.
Treatment of Overdose
In case of overdose, priorities are the re-establishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures (including oxygen, vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life support techniques.
Naloxone may not be effective in reversing any respiratory depression produced by Transtec 70µg/h. High doses of naloxone, 10-35 mg/70 kg, may be of limited value in the management of Transtec 70µg/h overdose. The onset of naloxone effect may be delayed by 30 minutes or more. Doxapram hydrochloride (a respiratory stimulant) has also been used.
Remove Transtec 70µg/h transdermal system immediately. Because the duration of reversal would be expected to be less than the duration of action of Transtec 70µg/h from Transtec 70µg/h transdermal system, carefully monitor the patient until spontaneous respiration is reliably re-established. Even in the face of improvement, continued medical monitoring is required because of the possibility of extended effects as Transtec 70µg/h continues to be absorbed from the skin. After removal of Transtec 70µg/h transdermal system, the mean Transtec 70µg/h concentrations decrease approximately 50% in 12 hours (range 10-24 hours) with an apparent terminal half-life of approximately 26 hours. Due to this long apparent terminal half-life, patients may require monitoring and treatment for at least 24 hours.
In an individual physically dependent on opioids, administration of an opioid receptor antagonist may precipitate an acute withdrawal syndrome. The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered. If a decision is made to treat serious respiratory depression in the physically dependent patient, administration of the antagonist should be begun with care and by titration with smaller than usual doses of the antagonist.
What should I avoid while taking Transtec 70µg/h?
This medication may impair your thinking or reactions. Avoid driving or operating machinery until you know how Transtec 70µg/h will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
Do not drink alcohol. Dangerous side effects or death could occur.
Avoid using any opioid pain medicine without approval from the doctor who is treating you with Transtec 70µg/h. Opioid pain medicine will not work as well while you are receiving Transtec 70µg/h. Talk with your doctor about other options for pain relief while you are using Transtec 70µg/h.
Transtec 70µg/h warnings
Impaired Respiration: As with other potent opioids, clinically significant respiratory depression may occur within the recommended dose range in patients receiving therapeutic doses of Transtec 70µg/h. Transtec 70µg/h (Transtec 70µg/h) should be used with caution in patients with compromised respiratory function (e.g., chronic obstructive pulmonary disease, cor pulmonale, decreased respiratory reserve, hypoxia, hypercapnia, or preexisting respiratory depression). Particular caution is advised if Transtec 70µg/h (Transtec 70µg/h) is administered to patients taking or recently receiving drugs with CNS/respiratory depressant effects. In patients with the physical and/or pharmacological risk factors above, the dose should be reduced by approximately one-half.
NALOXONE MAY NOT BE EFFECTIVE IN REVERSING THE RESPIRATORY DEPRESSION PRODUCED BY Transtec 70µg/h (Transtec 70µg/h). THEREFORE, AS WITH OTHER POTENT OPIOIDS, THE PRIMARY MANAGEMENT OF OVERDOSE SHOULD BE THE REESTABLISHMENT OF ADEQUATE VENTILATION WITH MECHANICAL ASSISTANCE OF RESPIRATION, IF REQUIRED.
Interaction with Other Central Nervous System Depressants: Patients receiving Transtec 70µg/h (Transtec 70µg/h) in the presence of other narcotic analgesics, general anesthetics, antihistamines, benzodiazepines, phenothiazines, other tranquilizers, sedative/hypnotics or other CNS depressants (including alcohol) may exhibit increased CNS depression. When such combined therapy is contemplated, it is particularly important that the dose of one or both agents be reduced.
Head Injury and Increased Intracranial Pressure: Transtec 70µg/h (Transtec 70µg/h), like other potent analgesics, may itself elevate cerebrospinal fluid pressure and should be used with caution in head injury, intracranial lesions and other circumstances where cerebrospinal pressure may be increased. Transtec 70µg/h (Transtec 70µg/h) can produce miosis and changes in the level of consciousness which may interfere with patient evaluation.
Use in Ambulatory Patients: Transtec 70µg/h (Transtec 70µg/h) may impair the mental or physical abilities required for the performance of potentially dangerous tasks such as driving a car or operating machinery. Therefore, Transtec 70µg/h (Transtec 70µg/h) should be administered with caution to ambulatory patients who should be warned to avoid such hazards.
Use in Narcotic-Dependent Patients: Because of the narcotic antagonist activity of Transtec 70µg/h (Transtec 70µg/h), use in the physically dependent individual may result in withdrawal effects.
What should I discuss with my healthcare provider before taking Transtec 70µg/h?
Do not use this medication if you are allergic to Transtec 70µg/h or naloxone (Narcan), or if you have used another narcotic drug within the past 4 hours.
To make sure you can safely take Transtec 70µg/h, tell your doctor if you have any of these other conditions:
- asthma, COPD, sleep apnea, or other breathing disorders;
- liver disease (especially hepatitis B or C);
- kidney disease;
- a thyroid disorder;
- stomach problems;
- enlarged prostate, urination problems;
- gallbladder disease;
- curvature of the spine;
- Addison's disease (an adrenal gland disorder);
- a history of mental illness, personality disorder, or psychotic episode;
- a history of drug or alcohol addiction; or
- a history of seizures, head injury, or brain tumor.
Transtec 70µg/h may be habit forming and should be used only by the person it was prescribed for. Never share Transtec 70µg/h with another person, especially someone with a history of drug abuse or addiction. Transtec 70µg/h can cause withdrawal effects in a person who is addicted to narcotics. Keep the medication in a place where others cannot get to it.
FDA pregnancy category C. It is not known whether Transtec 70µg/h will harm an unborn baby. Transtec 70µg/h may cause addiction or withdrawal symptoms in a newborn if the mother takes the medication during pregnancy. Tell your doctor if you are pregnant or plan to become pregnant while using Transtec 70µg/h.
Transtec 70µg/h can pass into breast milk and may harm a nursing baby. You should not breast-feed while you are using Transtec 70µg/h.
Do not give this medication to a child.
Transtec 70µg/h precautions
Transtec 70µg/h should be used with caution in patients with severely impaired respiratory function and in patients concurrently receiving monoamine oxidase inhibitors (MAOIs) or who have received MAOIs within the previous two weeks.
Transtec 70µg/h should be used with particular caution in patients with head injury, intracranial lesions or increased intracranial pressure, shock, a reduced level of consciousness of uncertain origin, or in patients with severe hepatic impairment.
Transtec 70µg/h may lower the seizure threshold in patients with a history of seizure disorder.
Severe febrile illness may increase the rate of Transtec 70µg/h absorption from Transtec 70µg/h.
Significant respiratory depression has been associated with Transtec 70µg/h, particularly by the intravenous route. A number of deaths have occurred when addicts have intravenously abused Transtec 70µg/h, usually with benzodiazepines concomitantly. Additional overdose deaths due to ethanol and benzodiazepines in combination with Transtec 70µg/h have been reported. Caution should be exercised when prescribing Transtec 70µg/h to patients known to have, or suspected of having, problems with drug or alcohol abuse or serious mental illness.
Transtec 70µg/h is not recommended for analgesia in the immediate post-operative period or in other situations characterized by rapidly varying analgesic requirement.
Transtec 70µg/h is a μ-opioid partial agonist.
Transtec 70µg/h produces morphine-like effects, including euphoria and physical dependence, but the magnitude of these effects is less than for comparable doses of full μ-opioid agonists. Administration of Transtec 70µg/h to persons who are physically dependent on full μ-opioid agonists may precipitate an abstinence syndrome depending on the level of physical dependence, and the timing and dose of Transtec 70µg/h.
Effects on Ability to Drive and Use Machines: Transtec 70µg/h may impair the ability to drive and operate machinery.
What happens if I miss a dose of Transtec 70µg/h?
Since Transtec 70µg/h is used on an as needed basis, you are not likely to miss a dose. Never use Transtec 70µg/h in larger amounts, or more often than recommended by your doctor.
