Oxycontin effects and Night Sweats
OxyContin addiction and side effects can be very difficult to handle.
This drug can lead to night sweats
sweating, nocturnal hydrosis, withdrawal, abuse and detox. This drug has
many warnings associated with it regardless of purchasing discount online or
generic. Some of this information can help you with addiction
as well as side effects. This information is always subject to change please
consult you doctor before taking this medicine.
WARNING:
OxyContin is an opioid agonist and a Schedule II controlled substance with
an abuse liability similar to morphine.
Oxycodone can be abused in a manner similar to other opioid agonists,
legal or illicit. This should be considered when prescribing or dispensing
OxyContin in situations where the physician or pharmacist is concerned about
an increased risk of misuse, abuse, or diversion.
OxyContin Tablets are a controlled-release oral formulation of oxycodone
hydrochloride indicated for the management of moderate to severe pain when a
continuous, around-the-clock analgesic is needed for an extended period of
time.
OxyContin Tablets are NOT intended for use as a prn analgesic.
OxyContin 80 mg and 160 mg Tablets ARE FOR USE IN OPIOID-TOLERANT PATIENTS ONLY. These tablet strengths may cause fatal respiratory depression when administered to patients not previously exposed to opioids.
OxyContin TABLETS ARE TO BE SWALLOWED WHOLE AND ARE NOT TO BE
BROKEN, CHEWED, OR CRUSHED. TAKING BROKEN, CHEWED, OR CRUSHED
OxyContin TABLETS LEADS TO RAPID RELEASE AND ABSORPTION OF A POTENTIALLY
FATAL DOSE OF OXYCODONE.
PRECAUTIONS
General
Opioid analgesics have a narrow therapeutic index in certain patient populations, especially when combined with CNS depressant drugs, and should be reserved for cases where the benefits of opioid analgesia outweigh the known risks of respiratory depression, altered mental state, and postural hypotension.
Use of OxyContin ® is associated with increased potential risks and should be used only with caution in the following conditions: acute alcoholism; adrenocortical insufficiency (e.g., Addison's disease); CNS depression or coma; delirium tremens; debilitated patients; kyphoscoliosis associated with respiratory depression; myxedema or hypothyroidism; prostatic hypertrophy or urethral stricture; severe impairment of hepatic, pulmonary or renal function; and toxic psychosis.
The administration of oxycodone may obscure the diagnosis or clinical course in patients with acute abdominal conditions. Oxycodone may aggravate convulsions in patients with convulsive disorders, and all opioids may induce or aggravate seizures in some clinical settings.
Interactions with other CNS Depressants
OxyContin should be used with caution and started in a reduced dosage
(1/3 to 1/2 of the usual dosage) in patients who are concurrently receiving
other central nervous system depressants including sedatives or hypnotics,
general anesthetics, phenothiazines, other tranquilizers, and alcohol.
Interactive effects resulting in respiratory depression, hypotension,
profound sedation, or coma may result if these drugs are taken in
combination with the usual doses of
OxyContin.
Interactions with Mixed Agonist/Antagonist Opioid Analgesics
Agonist/antagonist analgesics (i.e., pentazocine, nalbuphine, and butorphanol) should be administered with caution to a patient who has received or is receiving a course of therapy with a pure opioid agonist analgesic such as oxycodone. In this situation, mixed agonist/antagonist analgesics may reduce the analgesic effect of oxycodone and/or may precipitate withdrawal symptoms in these patients.
Ambulatory Surgery and Postoperative Use
OxyContin is not indicated for pre-emptive analgesia (administration pre-operatively for the management of postoperative pain).
OxyContin is not indicated for pain in the immediate postoperative period (the first 12 to 24 hours following surgery) for patients not previously taking the drug, because its safety in this setting has not been established.
OxyContin is not indicated for pain in the postoperative period if the pain is mild or not expected to persist for an extended period of time.
OxyContin is only indicated for postoperative use if the patient is already receiving the drug prior to surgery or if the postoperative pain is expected to be moderate to severe and persist for an extended period of time. Physicians should individualize treatment, moving from parenteral to oral analgesics as appropriate (See American Pain Society guidelines).
Patients who are already receiving
OxyContin ® Tablets as part
of ongoing analgesic therapy may be safely continued on the drug if
appropriate dosage adjustments are made considering the procedure, other
drugs given, and the temporary changes in physiology caused by the surgical
intervention (see DOSAGE AND ADMINISTRATION ).
OxyContin and other morphine-like opioids have been shown to decrease bowel motility. Ileus is a common postoperative complication, especially after intra-abdominal surgery with opioid analgesia. Caution should be taken to monitor for decreased bowel motility in postoperative patients receiving opioids. Standard supportive therapy should be implemented.
Use in Pancreatic/Biliary Tract Disease
Oxycodone may cause spasm of the sphincter of Oddi and should be used with caution in patients with biliary tract disease, including acute pancreatitis. Opioids like oxycodone may cause increases in the serum amylase level.
Tolerance and Physical Dependence
Tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia (in the absence of disease progression or other external factors). Physical dependence is manifested by withdrawal symptoms after abrupt discontinuation of a drug or upon administration of an antagonist. Physical dependence and tolerance are not unusual during chronic opioid therapy.
The opioid abstinence or withdrawal syndrome is characterized by some or all of the following: restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis. Other symptoms also may develop, including: irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate.
In general, opioids should not be abruptly discontinued (see DOSAGE AND ADMINISTRATION : Cessation of Therapy ).
Information for Patients/Caregivers
If clinically advisable, patients receiving
OxyContin Tablets or their caregivers should be given the following
information by the physician, nurse, pharmacist, or caregiver:
-
Patients should be
aware that
OxyContin Tablets contain oxycodone, which is a morphine-like substance. -
Patients should be
advised that
OxyContin Tablets were designed to work properly only if swallowed whole.
OxyContin Tablets will release all their contents at once if broken, chewed, or crushed, resulting in a risk of fatal overdose. - Patients should be advised to report episodes of breakthrough pain and adverse experiences occurring during therapy. Individualization of dosage is essential to make optimal use of this medication.
-
Patients should be
advised not to adjust the dose of
OxyContin ® without consulting the prescribing professional. -
Patients should be
advised that
OxyContin may impair mental and/or physical ability required for the performance of potentially hazardous tasks (e.g., driving, operating heavy machinery). -
Patients should not
combine
OxyContin with alcohol or other central nervous system depressants (sleep aids, tranquilizers) except by the orders of the prescribing physician, because dangerous additive effects may occur, resulting in serious injury or death. - Women of childbearing potential who become, or are planning to become, pregnant should be advised to consult their physician regarding the effects of analgesics and other drug use during pregnancy on themselves and their unborn child.
-
Patients should be
advised that
OxyContin is a potential drug of abuse. They should protect it from theft, and it should never be given to anyone other than the individual for whom it was prescribed. - Patients should be advised that they may pass empty matrix "ghosts" (tablets) via colostomy or in the stool, and that this is of no concern since the active medication has already been absorbed.
-
Patients should be
advised that if they have been receiving treatment with
OxyContin for more than a few weeks and cessation of therapy is indicated, it may be appropriate to taper the
OxyContin dose, rather than abruptly discontinue it, due to the risk of precipitating withdrawal symptoms. Their physician can provide a dose schedule to accomplish a gradual discontinuation of the medication. -
Patients should be
instructed to keep
OxyContin in a secure place out of the reach of children. When
OxyContin is no longer needed, the unused tablets should be destroyed by flushing down the toilet.
Use in Drug and Alcohol Addiction
OxyContin is an opioid with no approved use in the management of addictive disorders. Its proper usage in individuals with drug or alcohol dependence, either active or in remission, is for the management of pain requiring opioid analgesia.
Drug-Drug Interactions
Opioid analgesics, including
OxyContin ® , may enhance the
neuromuscular blocking action of skeletal muscle relaxants and produce an
increased degree of respiratory depression.
Oxycodone is metabolized in part to oxymorphone via cytochrome P450 2D6. While this pathway may be blocked by a variety of drugs (e.g., certain cardiovascular drugs including amiodarone and quinidine as well as polycyclic antidepressants), such blockade has not yet been shown to be of clinical significance with this agent. Clinicians should be aware of this possible interaction, however.
Use with CNS Depressants
OxyContin, like all opioid analgesics, should be started at 1/3 to 1/2 of the usual dosage in patients who are concurrently receiving other central nervous system depressants including sedatives or hypnotics, general anesthetics, phenothiazines, centrally acting anti-emetics, tranquilizers, and alcohol because respiratory depression, hypotension, and profound sedation or coma may result. No specific interaction between oxycodone and monoamine oxidase inhibitors has been observed, but caution in the use of any opioid in patients taking this class of drugs is appropriate.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Studies of oxycodone to evaluate its carcinogenic potential have not been conducted.
Oxycodone was not mutagenic in the following assays: Ames Salmonella and E. coli test with and without metabolic activation at doses of up to 5000 µg, chromosomal aberration test in human lymphocytes in the absence of metabolic activation at doses of up to 1500 µg/mL and with activation 48 hours after exposure at doses of up to 5000 µg/mL, and in the in vivo bone marrow micronucleus test in mice (at plasma levels of up to 48 µg/mL). Oxycodone was clastogenic in the human lymphocyte chromosomal assay in the presence of metabolic activation in the human chromosomal aberration test (at greater than or equal to 1250 µg/mL) at 24 but not 48 hours of exposure and in the mouse lymphoma assay at doses of 50 µg/mL or greater with metabolic activation and at 400 µg/mL or greater without metabolic activation.
Pregnancy
Teratogenic Effects -- Category B: Reproduction studies have been performed in rats and rabbits by oral administration at doses up to 8 mg/kg and 125 mg/kg, respectively. These doses are 3 and 46 times a human dose of 160 mg/day, based on mg/kg basis. The results did not reveal evidence of harm to the fetus due to oxycodone. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Labor and Delivery
OxyContin ® is not recommended for use in women during and immediately prior to labor and delivery because oral opioids may cause respiratory depression in the newborn. Neonates whose mothers have been taking oxycodone chronically may exhibit respiratory depression and/or withdrawal symptoms, either at birth and/or in the nursery.
Nursing Mothers
Low concentrations of oxycodone have been detected in breast milk.
Withdrawal symptoms can occur in breast-feeding infants when maternal
administration of an opioid analgesic is stopped. Ordinarily, nursing should
not be undertaken while a patient is receiving
OxyContin because of the possibility of sedation and/or respiratory
depression in the infant.
Pediatric Use
Safety and effectiveness of OxyContin have not been established in pediatric patients below the age of 18. It must be remembered that OxyContin Tablets cannot be crushed or divided for administration.
Geriatric Use
In controlled pharmacokinetic studies in elderly subjects (greater than 65 years) the clearance of oxycodone appeared to be slightly reduced. Compared to young adults, the plasma concentrations of oxycodone were increased approximately 15% (see PHARMACOKINETICS AND METABOLISM ). Of the total number of subjects (445) in clinical studies of OxyContin, 148 (33.3%) were age 65 and older (including those age 75 and older) while 40 (9.0%) were age 75 and older. In clinical trials with appropriate initiation of therapy and dose titration, no untoward or unexpected side effects were seen in the elderly patients who received OxyContin. Thus, the usual doses and dosing intervals are appropriate for these patients. As with all opioids, the starting dose should be reduced to 1/3 to 1/2 of the usual dosage in debilitated, non-tolerant patients. Respiratory depression is the chief hazard in elderly or debilitated patients, usually following large initial doses in non-tolerant patients, or when opioids are given in conjunction with other agents that depress respiration.
Laboratory Monitoring
Due to the broad range of plasma concentrations seen in clinical populations, the varying degrees of pain, and the development of tolerance, plasma oxycodone measurements are usually not helpful in clinical management. Plasma concentrations of the active drug substance may be of value in selected, unusual or complex cases.
Hepatic Impairment
A study of
OxyContin in patients with hepatic impairment indicates greater plasma
concentrations than those with normal function. The initiation of therapy at
1/3 to 1/2 the usual doses and careful dose titration is warranted.
Renal Impairment
In patients with renal impairment, as evidenced by decreased creatinine clearance (<60 mL/min), the concentrations of oxycodone in the plasma are approximately 50% higher than in subjects with normal renal function. Dose initiation should follow a conservative approach. Dosages should be adjusted according to the clinical situation.
Gender Differences
In pharmacokinetic studies, opioid-naive females demonstrate up to 25% higher average plasma concentrations and greater frequency of typical opioid adverse events than males, even after adjustment for body weight. The clinical relevance of a difference of this magnitude is low for a drug intended for chronic usage at individualized dosages, and there was no male/female difference detected for efficacy or adverse events in clinical trials.
ADVERSE REACTIONS
The safety of
OxyContin ® was evaluated in
double-blind clinical trials involving 713 patients with moderate to severe
pain of various etiologies. In open-label studies of cancer pain, 187
patients received
OxyContin in total daily doses ranging from 20 mg to 640 mg per day. The
average total daily dose was approximately 105 mg per day.
Serious adverse reactions which may be associated with OxyContin Tablet therapy in clinical use are those observed with other opioid analgesics, including respiratory depression, apnea, respiratory arrest, and (to an even lesser degree) circulatory depression, hypotension, or shock (see OVERDOSAGE ).
The non-serious adverse events seen on initiation of therapy with
OxyContin are typical opioid side effects. These events are dose-dependent,
and their frequency depends upon the dose, the clinical setting, the
patient's level of opioid tolerance, and host factors specific to the
individual. They should be expected and managed as a part of opioid
analgesia. The most frequent (>5%) include: constipation, nausea,
somnolence, dizziness, vomiting, pruritus, headache, dry mouth,
sweating, and asthenia.
In many cases the frequency of these events during initiation of therapy may be minimized by careful individualization of starting dosage, slow titration, and the avoidance of large swings in the plasma concentrations of the opioid. Many of these adverse events will cease or decrease in intensity as OxyContin therapy is continued and some degree of tolerance is developed.
Clinical trials comparing OxyContin with immediate-release oxycodone and placebo revealed a similar adverse event profile between OxyContin and immediate-release oxycodone. The most common adverse events (>5%) reported by patients at least once during therapy were:
