propoxyphene methylene blue

Applies to: PC-CAP (aspirin / caffeine / propoxyphene) and methylene blue

CONTRAINDICATED: Coadministration of monoamine oxidase inhibitors (MAOIs) with certain opioids has been associated with rare reports of severe and fatal adverse reactions. There appear to be two types of interaction, an excitatory and a depressive one. Symptoms of the excitatory reaction may include agitation, headache, diaphoresis, hyperpyrexia, flushing, shivering, myoclonus, rigidity, tremor, diarrhea, hypertension, tachycardia, seizures, and coma. Death has occurred in some cases. The exact mechanism of interaction is unknown, but may involve excessive serotonergic activity in the central nervous system (i.e., serotonin syndrome). The interaction is unpredictable and has been reported primarily with meperidine or fentanyl and various MAOIs including phenelzine, tranylcypromine, linezolid, moclobemide, and selegiline. Fatal hyperpyrexia and hypertension have also been observed in animal studies with meperidine and phenelzine or furazolidone. In contrast, symptoms of the depressive reaction probably stem from potentiation of CNS effects by MAOIs and include respiratory depression, cyanosis, hypotension, and coma.

MANAGEMENT: Meperidine and fentanyl should not be used with MAOIs or other agents that possess MAOI activity (e.g., furazolidone, linezolid, methylene blue, procarbazine). Some manufacturers of MAOIs also contraindicate the concomitant use of propoxyphene and methadone due to their possible serotonergic effects. At least 14 days should elapse between discontinuation of MAOI therapy and initiation of treatment with these opioids. Although morphine may also have significant CNS interactions with MAOIs, it is generally considered a safer alternative in patients treated with MAOIs who require a narcotic analgesic. A sensitivity test should be performed in which repeated, small, incremental doses of morphine are administered over the course of several hours while overall clinical status and vital signs are carefully monitored.

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 and food interactions

Major

propoxyphene food

Applies to: PC-CAP (aspirin / caffeine / propoxyphene)

GENERALLY AVOID: Alcohol may have additive CNS- and/or respiratory-depressant effects with propoxyphene. Misuse of propoxyphene, either alone or in combination with other CNS depressants, has been a major cause of drug-related deaths, particularly in patients with a history of emotional disturbances, suicidal ideation, or alcohol and drug abuse.

MANAGEMENT: The use of alcohol during propoxyphene therapy should be avoided. Patients should be warned not to exceed the recommended dosage of propoxyphene and to avoid activities requiring mental alertness until they know how these agents affect them.

aspirin food

Applies to: PC-CAP (aspirin / caffeine / propoxyphene)

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.

The effect of grapefruit juice on the pharmacologic activity of caffeine is controversial. One report suggests that grapefruit juice increases the effect of caffeine. The proposed mechanism is inhibition of cytochrome P-450 metabolism of caffeine. However, a well-conducted pharmacokinetic/pharmacodynamic study did not demonstrate this effect. The clinical significance of this potential interaction is unknown.

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.
