Side Effects, Interactions, Warning, Dosage Uses. SIDE EFFECTSSerious adverse reactions that may be associated with PERCODAN aspirin and oxycodone hydrochloride tablet use include respiratory depression, apnea, respiratory arrest, circulatory depression, hypotension. OVERDOSE. The most frequently observed non serious adverse reactions include lightheadedness, dizziness, drowsiness or sedation, nausea, and vomiting. These effects seem to be more prominent in ambulatory than in nonambulatory patients, and some of these adverse reactions may be alleviated if the patient lies down. Other adverse reactions include euphoria, dysphoria, constipation and pruritus. Aspirin may increase the likelihood of hemorrhage due to its effect on the gastric mucosa and platelet function. Furthermore, aspirin has the potential to cause anaphylaxis in hypersensitive patients as well as angioedema especially in patients with chronic urticaria. Other adverse reactions due to aspirin use include anorexia, reversible hepatotoxicity, leukopenia, thrombocytopenia, purpura, decreased plasma iron concentration, and shortened erythrocyte survival time. Other adverse reactions obtained from postmarketing experiences with PERCODAN aspirin and oxycodone hydrochloride tablets are listed by organ system and in decreasing order of severity andor frequency as follows Body as a Wholeallergic reaction, malaise, asthenia, headache, anaphylaxis, fever, hypothermia, thirst, increased sweating, accident, accidental overdose, non accidental overdose.

A4 Inhibitors and CYP4. Inducers. Oxycodone is extensively metabolized by multiple metabolic pathways. CYP3. A4 is the major enzyme involved in noroxycodone formation followed by CYP2. B6, CYP2. C91. 9 and CYP2. D6. Drugs that inhibit CYP3. A4 activity, such as macrolide antibiotics e. Similarly, CYP4. 50 inducers, such as rifampin, carbamazepine, and phenytoin, may induce the metabolism of oxycodone and, therefore, may cause increased clearance of the drug which could lead to a decrease in oxycodone plasma concentrations, lack of efficacy or, possibly, development of an abstinence syndrome in a patient who had developed physical dependence to oxycodone. If co administration with PERCODAN aspirin and oxycodone hydrochloride is necessary, caution is advised when initiating therapy with, currently taking, or discontinuing CYP3. A4 inhibitors or CYP4. Evaluate these patients at frequent intervals and consider dose adjustments until stable drug effects are achieved. Skeletal Muscle Relaxants. Opioid analgesics may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increase in the degree of respiratory depression. CNS Depressants. Patients receiving CNS depressants such as other opioid analgesics, general anesthetics, phenothiazines, other tranquilizers, centrally acting anti emetics, sedative hypnotics or other CNS depressants including alcohol concomitantly with PERCODAN aspirin and oxycodone hydrochloride tablets may exhibit an additive CNS depression. When such combined therapy is contemplated, the dose of one or both agents should be reduced. Analgesics. Agonistantagonist analgesics i. These agonistantagonist analgesics may reduce the analgesic effect of oxycodone or may precipitate withdrawal symptoms. DrugDrug Interactions with Aspirin. Angiotensin Converting Enzyme ACE Inhibitors The hyponatremic and hypotensive effects of ACE inhibitors may be diminished by the concomitant administration. Acetazolamide Concurrent use of aspirin and acetazolamide can lead. Anticoagulant Therapy Heparin and Warfarin Patients on anticoagulation. Aspirin can displace warfarin from protein binding. Aspirin can increase the anticoagulant activity of heparin, increasing. Anticonvulsants Salicylate can displace protein bound phenytoin and. Beta Blockers The hypotensive effects of beta blockers may be diminished. Diuretics The effectiveness of diuretics in patients with underlying. Methotrexate Aspirin may enhance the serious side and toxicity of methotrexate. Nonsteroidal Anti inflammatory Drugs NSAIDs The concurrent use of. NSAIDs should be avoided because this may increase bleeding. ISOLUTE SLE Supported Liquid extraction products page. ISOLUTE SLE Supported Liquid Extraction Products LoadWaitElute Sample Preparation.

Oral Hypoglycemics Agents Aspirin may increase the serum glucose lowering. Uricosuric Agents Salicylates antagonize the uricosuric action of probenecid. DrugLaboratory Test Interactions. Depending on the sensitivityspecificity and the test methodology, the individual components of PERCODAN aspirin and oxycodone hydrochloride tablets may cross react with assays used in the preliminary detection of cocaine primary urinary metabolite, benzoylecgonine or marijuana cannabinoids in human urine. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result.

Moreover, clinical considerations and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used. Salicylates may increase the protein bound iodine FBI result by competing for the protein binding sites on pre albumin and possibly thyroid binding globulins. Drug Abuse And Dependence. PERCODAN aspirin and oxycodone hydrochloride tablets are a Schedule II controlled substance. Oxycodone is a mu agonist opioid with an abuse liability similar to morphine.
