Interactions between your drugs

Moderate

aspirin heparin

Applies to: Percodan-Demi (aspirin / oxycodone) and heparin

GENERALLY AVOID: Theoretically, the coadministration of nonsteroidal anti-inflammatory drugs (NSAIDs) and heparin or low molecular weight heparin (LMWH) may potentiate the risk of bleeding. NSAIDs interfere with platelet adhesion and aggregation and may prolong bleeding time in healthy individuals. While these effects are generally slight and of relatively short duration for most NSAIDs (except aspirin) at recommended dosages, they may be of pronounced clinical significance when combined with the inhibitory effects of heparin on the clotting cascade. However, little clinical data exist regarding an actual interaction. In a controlled, randomized prospective study, 60 patients undergoing total hip replacement received enoxaparin (40 mg subcutaneously 12 hours pre- and every 24 hours postoperatively for 10 days) and analgesia with either ketorolac tromethamine (30 mg IM on induction of anesthesia and every 24 hours postoperatively for 4 days) or an opioid plus acetaminophen. The authors reported no significant differences between the two groups for intraoperative blood loss, postoperative drainage, transfusion requirements, bruising, wound oozing, and leg swelling. However, there have been anecdotal reports of hemorrhagic complications in surgical patients treated with NSAIDs alone and in combination with a LMWH. In addition, NSAIDs are known to cause dose-related gastrointestinal bleeding, which may be complicated by anticoagulant therapy.

MANAGEMENT: Until further data are available, products containing NSAIDs, especially if given chronically or in high dosages, should preferably be avoided in patients receiving heparin or LMWH. Close clinical and laboratory observation for bleeding complications is recommended if concurrent therapy is necessary.

Drug and food interactions

Major

oxyCODONE food

Applies to: Percodan-Demi (aspirin / oxycodone)

GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including oxycodone. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of oxycodone. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of oxycodone by certain compounds present in grapefruit, resulting in decreased formation of metabolites noroxycodone and noroxymorphone and increased formation of oxymorphone due to a presumed shifting of oxycodone metabolism towards the CYP450 2D6-mediated route. In 12 healthy, nonsmoking volunteers, administration of a single 10 mg oral dose of oxycodone hydrochloride on day 4 of a grapefruit juice treatment phase (200 mL three times a day for 5 days) increased mean oxycodone peak plasma concentration (Cmax), systemic exposure (AUC) and half-life by 48%, 67% and 17% (from 3.5 to 4.1 hours), respectively, compared to administration during an equivalent water treatment phase. Grapefruit juice also decreased the metabolite-to-parent AUC ratio of noroxycodone by 44% and that of noroxymorphone by 45%. In addition, oxymorphone Cmax and AUC increased by 32% and 56%, but the metabolite-to-parent AUC ratio remained unchanged. Pharmacodynamic changes were modest and only self-reported performance was significantly impaired after grapefruit juice. Analgesic effects were not affected.

MANAGEMENT: Patients should not consume alcoholic beverages or use drug products that contain alcohol during treatment with oxycodone. Any history of alcohol or illicit drug use should be considered when prescribing oxycodone, and therapy initiated at a lower dosage if necessary. Patients should be closely monitored for signs and symptoms of sedation, respiratory depression, and hypotension. Due to a high degree of interpatient variability with respect to grapefruit juice interactions, patients treated with oxycodone may also want to avoid or limit the consumption of grapefruit and grapefruit juice.

Moderate

aspirin food

Applies to: Percodan-Demi (aspirin / oxycodone)

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
