SIDE EFFECTS

The most frequently observed adverse reactions includelightheadedness, dizziness, sedation, nausea and vomiting. These effects seem to be more prominent in ambulatory than in non-ambulatory patients, and some of these adverse reactions may be alleviated if the patient lies down.

Other adverse reactions include allergic reactions,euphoria,dysphoria, constipation, skin rash andpruritus. At higher doses, oxycodone has most of the disadvantages ofmorphineincludingrespiratory depression.

Drug Abuse And Dependence

TYLOX(羟考酮和对乙酰氨基酚capsules) capsules are a Schedule II controlled substance.

Oxycodone can produce drug dependence and has the potential for being abused. (See警告)

DRUG INTERACTIONS

Patients receiving othernarcoticanalgesics, general anesthetics, phenothiazines, other tranquilizers,sedative-hypnotics or other CNS depressants (including alcohol) concomitantly with TYLOX (oxycodone and acetaminophen capsules) may exhibit an additive CNS depression. When such combined therapy is contemplated, the dose of one or both agents should be reduced.

The concurrent use of anticholinergics with narcotics may produceparalytic ileus.

警告

Contains sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severeasthmaticepisodes in certain susceptible people. The overallprevalenceofsulfite sensitivityin the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people.

Drug Dependence

Oxycodone can produce drug dependence of the morphine type and, therefore, has the potential for being abused. Psychic dependence, physical dependence and tolerance may develop upon repeated administration of TYLOX (oxycodone and acetaminophen capsules) (oxycodone and acetaminophen capsules), and it should be prescribed and administered with the same degree of caution appropriate to the use of other oral narcotic-containing medications. Like other narcotic-containing medications, TYLOX (oxycodone and acetaminophen capsules) is subject to the Federal Control Substances Act (Schedule II).

PRECAUTIONS

General

Head Injury and Increased Intracranial Pressure:The respiratory depressant effects of narcotics and their capacity to elevate cerebrospinal fluid pressure may be markedly exaggerated in the presence ofhead injury, other intracranial lesions or a pre-existing increase in intracranial pressure. Furthermore, narcotics produce adverse reactions which may obscure the clinical course of patients with head injuries.

Acute Abdominal Conditions:The administration of TYLOX (oxycodone and acetaminophen capsules) (oxycodone and acetaminophen capsules) or other narcotics may obscure the diagnosis or clinical course in patients with acute abdominal conditions.

Special Risk Patients:TYLOX(羟考酮和对乙酰氨基酚capsules) should be given with caution to certain patients such as the elderly or debilitated, and those with severe impairment of hepatic or renal function,hypothyroidism, Addison's disease, and prostatichypertrophyor urethralstricture.

Usage in Pregnancy

Pregnancy Category C. Animal reproductive studies have not been conducted with TYLOX (oxycodone and acetaminophen capsules) . It is also not known whether TYLOX (oxycodone and acetaminophen capsules) can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. TYLOX (oxycodone and acetaminophen capsules) should not be given to a pregnant woman unless in the judgment of the physician, the potential benefits outweigh the possible hazards.

Nonteratogenic Effects:Use of narcotics during pregnancy may produce physical dependence in theneonate.

Labor and Delivery

As with all narcotics, administration of TYLOX (oxycodone and acetaminophen capsules) to the mother shortly before delivery may result in some degree of respiratory depression in the newborn and the mother, especially if higher doses are used.

Nursing Mothers

目前尚不清楚TYLOX组件(oxycodone and acetaminophen capsules) are excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when TYLOX (oxycodone and acetaminophen capsules) is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in children have not been established.

OVERDOSE

Acetaminophen

Signs and Symptoms:In acute acetaminophen overdosage, dose-dependent potentially fatal hepaticnecrosisis the most seriousadverse effect. Renal tubular necrosis,hypoglycemiccoma andthrombocytopeniamay also occur.

In adults, hepatic toxicity has rarely been reported with acute overdoses of less than 10 grams and fatalities with less than 15 grams. Importantly, young children seem to be more resistant than adults to thehepatotoxiceffect of an acetaminophen overdose. Despite this, the measures outlined below should be initiated in any adult or child suspected of having ingested an acetaminophen overdose.

Early symptoms following a potentially hepatotoxic overdose may include: nausea, vomiting, diaphoresis and generalmalaise. Clinical and laboratory evidence of hepatic toxicity may not be apparent until 48 to 72 hours post-ingestion.

Treatment:The stomach should be emptied promptly by lavage or by induction ofemesiswith syrup ofipecac. Patients' estimates of the quantity of a drug ingested are notoriously unreliable. Therefore, if an acetaminophen overdose is suspected, a serum acetaminophen assay should be obtained as early as possible, but no sooner than four hours following ingestion. Liver function studies should be obtained initially and repeated at 24-hour intervals.

Theantidote, N-acetylcysteine, should be administered as early as possible, and within 16 hours of the overdose ingestion for optimal results. Following recovery, there are noresidual, structural, or functional hepatic abnormalities.

Oxycodone

Signs and Symptoms:Serious overdosage with oxycodone is characterized by respiratory depression (a decrease inrespiratory rateand/or tidal volume, Cheyne-Stokesrespiration,cyanosis), extremesomnolenceprogressing to stupor or coma,skeletal muscleflaccidity, cold and clammy skin, and sometimesbradycardiaandhypotension. In severe overdosage,apnea,circulatorycollapse, cardiac arrest and death may occur.

Treatment:Primary attention should be given to the reestablishment of adequate respiratory exchange through provision of apatentairway and the institution of assisted or controlledventilation. The narcoticantagonistnaloxonehydrochloride is a specific antidote against respiratory depression which may result from overdosage or unusual sensitivity to narcotics, including oxycodone. Therefore, an appropriate dose of naloxone hydrochloride (usual initial adult dose 0.4 mg to 2 mg) should be administered preferably by the intravenous route and simultaneously with efforts at respiratoryresuscitation(seepackage insert). Since the duration of action of oxycodone may exceed that of the antagonist, the patient should be kept under continued surveillance and repeated doses of the antagonist should be administered as needed to maintain adequate respiration.

An antagonist should not be administered in the absence of clinically significant respiratory orcardiovasculardepression. Oxygen, intravenous fluids, vasopressors and other supportive measures should be employed as indicated.

Gastricemptying may be useful in removing unabsorbed drug.

CONTRAINDICATIONS

TYLOX(羟考酮和对乙酰氨基酚capsules) should not be administered to patients who are hypersensitive to any component.

CLINICAL PHARMACOLOGY

The principal ingredient, oxycodone, is a semisynthetic narcoticanalgesicwith multiple actions qualitatively similar to those of morphine; the most prominent of these involve thecentral nervous systemand organs composed ofsmooth muscle. The principal actions of therapeutic value of the oxycodone in TYLOX (oxycodone and acetaminophen capsules) areanalgesiaand sedation.

Oxycodone is similar to codeine andmethadonein that it retains at least one-half of its analgesic activity when administered orally.

Acetaminophen is a non-opiate, non-salicylate analgesic andantipyretic.

PATIENT INFORMATION

Oxycodone may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery. The patient using TYLOX (oxycodone and acetaminophen capsules) should be cautioned accordingly.
