For healthcare professionals
Applies to aspirin / caffeine / propoxyphene: oral capsule.
General adverse events
In general, many side effects noted with aspirin use have been dose related.
Consumption of higher doses of caffeine (greater than 600 mg/day) has lead to caffeinism. Caffeinism is a syndrome characterized by anxiety, restlessness, and sleep disorders (similar to anxiety states). It has also been reported that chronic, heavy caffeine ingestion may be associated with depression. Caffeine may cause anxiety and panic in panic disorder patients and may aggravate PMS.
General side effects including drug tolerance and influenza type illness have been reported with the use of propoxyphene.[Ref]
Renal
Renal side effects of aspirin have included reduction in glomerular filtration rate (particularly in patients who are sodium restricted or who exhibit diminished effective arterial blood volume, such as patients with advanced heart failure or cirrhosis), interstitial nephritis, papillary necrosis, elevations in serum creatinine, elevations in blood urea nitrogen, proteinuria, hematuria, and renal failure.
Renal side effects of propoxyphene have included a single case of nephrogenic diabetes insipidus following an overdose of propoxyphene (however, other causes of diabetes insipidus in that patient were not rigorously excluded).[Ref]
The mechanism of an aspirin-induced decrease in renal function may be related to inhibition of renal prostaglandin synthesis with consequent decreases in renal blood flow. Vasodilating renal prostaglandins may be particularly important in patients who exhibit arterial underfilling (i.e. heart failure, cirrhosis). The administration of high doses of NSAIDs to such patients has produced acute renal failure in rare instances.[Ref]
Hematologic
Hematologic side effects of aspirin (in addition to predictable antiplatelet effects which may result in hemorrhage) have included increased blood fibrinolytic activity. In addition, hypoprothrombinemia, thrombocytopenia, thrombocyturia, megaloblastic anemia, and pancytopenia have been reported rarely. Aplastic anemia has also been reported.
Hematologic side effects of propoxyphene have rarely included cases of hemolytic anemia, pancytopenia, and disseminated intravascular coagulation after administration (or abuse) of propoxyphene-containing compounds.[Ref]
Hypersensitivity
Hypersensitivity side effects to aspirin have included bronchospasm, rhinitis, conjunctivitis, urticaria, angioedema, and anaphylaxis. Approximately 10% to 30% of asthmatics are aspirin-sensitive (with the clinical triad of aspirin sensitivity, bronchial asthma, and nasal polyps).
Hypersensitivity side effects to propoxyphene have also been reported.[Ref]
The mechanism of aspirin-induced hypersensitivity may be related to an up-regulation of the 5-lipoxygenase pathway of arachidonic acid metabolism with a resulting increase in the products of 5-lipoxygenase (such as leukotrienes).[Ref]
Gastrointestinal
Endoscopically identifiable gastric mucosal lesions occur in most patients who receive a single dose of aspirin. Clinically evident gastrointestinal bleeding has been reported in as many as 3% of treated elderly patients. Anorectal ulceration and rectal stenosis have been reported in patients who abuse aspirin-containing rectal suppositories. One case-controlled study has suggested that an association between aspirin (and other NSAID) consumption and appendicitis may exist.
A case of ischemic colitis has been reported following an overdose of propoxyphene which was complicated by severe hypotension.[Ref]
Gastrointestinal side effects have been common and included epigastric distress (in as many as 83% of patients treated with regular aspirin), abdominal discomfort or pain, endoscopically identifiable gastric mucosal lesions, nausea, and vomiting. More serious gastrointestinal effects have included hemorrhage, peptic ulcers, perforation, and esophageal ulcerations.
In clinical trials of caffeine citrate, five cases of necrotizing enterocolitis were reported among the 46 infants exposed to the caffeine citrate injection.
Gastrointestinal side effects of propoxyphene have included nausea, vomiting, and constipation which have been relatively common. Gastrointestinal bleeding and acute pancreatitis have also been reported with the use of propoxyphene.[Ref]
Other
Other side effects have rarely included Reye's syndrome which has been associated with aspirin use in children with an acute viral illness. Reye's syndrome has also been reported even more rarely in adults.
In one study of the effects of caffeine, 634 women with fibrocystic breast disease (compared to 1066 women without the disease), the occurrence of fibrocystic breast disease was positively associated with average daily consumption of caffeine. Women who consumed 31 to 250 mg/day of caffeine were reported to have a 1.5 times increase in odds to have the disease. Women who consumed over 500 mg/day of caffeine were reported to have a 2.3 times increase in odds.
Other side effects of propoxyphene have included dependence (although the abuse liability of propoxyphene has been less than that of some other narcotic analgesics). Withdrawal symptoms after either abrupt cessation or fast tapering may occur and include agitation, restlessness, anxiety, insomnia, tremor, tachycardia, hallucinations, psychosis, abdominal cramps, vomiting, sweating, and seizures.
Drug toxicity, multiple drug overdose, and narcotic overdose have also been reported with propoxyphene.
Sensorineural deafness has been reported following chronic abuse and/or large doses of propoxyphene-containing compounds. Optic atrophy has been reported following overdose.[Ref]
Reye's syndrome typically involves vomiting, neurologic dysfunction, and hepatic dysfunction during or shortly after an acute viral infection.[Ref]
Dermatologic
Dermatologic side effects from the use of aspirin have been reported rarely and have included Stevens-Johnson syndrome and a lichenoid eruption.
Dermatologic side effects of propoxyphene including rashes and itch have been reported.[Ref]
Hepatic
Hepatic side effects including cases of aspirin-induced hepatotoxicity and cholestatic hepatitis, particularly at high doses, have been reported rarely.
Hepatic side effects of propoxyphene have included elevated liver function tests, jaundice, hepatic steatosis, hepatomegaly, hepatocellular injury, and hepatotoxicity.[Ref]
Oncologic
Oncologic side effects of chronic aspirin use have included a possible decrease in the risk of large bowel neoplasms. This has been suggested in several epidemiologic studies. Other studies have not found such a beneficial effect.[Ref]
Metabolic
Metabolic side effects of aspirin have included dehydration and hyperkalemia. Respiratory alkalosis and metabolic acidosis, particularly during salicylate toxicity, have been reported. A case of hypoglycemia has been reported in a patient on hemodialysis. Salicylates have also been reported to displace triiodothyronine (T3) and thyroxine (T4) from protein binding sites. The initial effect is an increase in serum free T4 concentrations.
Metabolic side effects including metabolic acidosis have been reported with the use of propoxyphene. Cases of severe hypoglycemia have been reported in patients with chronic renal failure.[Ref]
Cardiovascular
Cardiovascular side effects of aspirin have been reported rarely and have included salicylate-induced variant angina, ventricular ectopy, conduction abnormalities, and hypotension, particularly during salicylate toxicity.
Cardiovascular side effects of propoxyphene have included arrhythmia, bradycardia, cardiac/respiratory arrest, congestive arrest, congestive heart failure (CHF), tachycardia, myocardial infarction (MI), hypotension, decreased blood pressure, elevated heart rate, abnormal heart rate, and dizziness. A variety of arrhythmias (including heart block) have been reported most often in association with propoxyphene overdose.[Ref]
Some of the cardiotoxic effects reported in association with propoxyphene may be attributable to its major active metabolite, norpropoxyphene.[Ref]
Nervous system
Nervous system side effects in patients receiving aspirin have included agitation, cerebral edema, coma, confusion, dizziness, headache, cranial hemorrhage, lethargy, and seizures. Tinnitus and subjective hearing loss (or both) may occur. Some investigators have reported that modest doses may result in decreased frequency selectivity and may therefore impair hearing performance, particularly in the setting of background noise.
Nervous system side effects from propoxyphene have included dizziness, sedation, stupor, delirium, somnolence, ataxia, coma, syncope, and respiratory depression. The sedative effects of propoxyphene have been associated with a 60% increased risk of hip fracture in elderly patients.[Ref]
Regarding the use of aspirin, some investigators have suggested that tinnitus may be a less reliable indicator of salicylate toxicity than previously believed. Patients with high frequency hearing loss may have difficulty perceiving tinnitus. In a study of rheumatoid arthritis patients, those with tinnitus had no greater salicylate levels than those without tinnitus. Elderly patients may be less likely to perceive tinnitus than younger patients.[Ref]
Musculoskeletal
Musculoskeletal side effects including rhabdomyolysis have occurred in patients receiving aspirin.
Musculoskeletal side effects of propoxyphene including myopathy and rhabdomyolysis have been reported after chronic oral use.[Ref]
Respiratory
Respiratory side effects including hyperpnea, pulmonary edema, and tachypnea have occurred in patients receiving aspirin.
Respiratory side effects including dyspnea have been reported with the use of propoxyphene.[Ref]
Genitourinary
Genitourinary side effects of interstitial nephritis, papillary necrosis, proteinuria, renal insufficiency, and renal failure have occurred in patients receiving aspirin.
Genitourinary side effects of propoxyphene including a case of retroperitoneal fibrosis have been reported.[Ref]
Endocrine
Endocrine side effects of aspirin use have included hypoglycemia (children) and hyperglycemia.[Ref]
Ocular
Ocular side effects including cases of localized periorbital edema have been reported rarely in patients receiving aspirin.
Ocular side effects including eye swelling and vision blurred have been reported with the use of propoxyphene.[Ref]
Psychiatric
Psychiatric side effects including abnormal behavior, confusional state, hallucinations, and mental status change have been reported with the use of propoxyphene.[Ref]
