For Healthcare Professionals
Applies to aspirin / carisoprodol / codeine: oral tablet
Gastrointestinal side effects are common and have 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 include hemorrhage, peptic ulcers, perforation, and esophageal ulcerations.
Gastrointestinal side effects of carisoprodol have included nausea, vomiting, hiccups, and epigastric distress.
Nausea, vomiting, and constipation have been reported frequently with the use of codeine. Severe constipation and ileus resulting in colonic perforation have been also reported. Four cases of acute pancreatitis have been reported.[Ref]
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.[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.
Central respiratory depression may occur with the use of carisoprodol, particularly at high doses.
Opioids may result in psychotic symptoms in some patients.
One retrospective study of elderly patients who sustained a hip fracture suggested that the relative risk of hip fracture was 1.6 in patients using codeine compared to age-matched non-users.[Ref]
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 of carisoprodol have included drowsiness and sedation most often. There have been postmarketing reports of motor vehicle accidents associated with the use of carisoprodol. Dizziness, headache, tremor, agitation, insomnia, syncope, and ataxia have also been reported.
Nervous system side effects from codeine have included mental and respiratory depression, stupor, delirium, somnolence, and dysphoria. An increased risk of falls and hip fractures has been associated with codeine therapy, particularly in the elderly.[Ref]
Other side effects of aspirin have included Reye's syndrome. Reye's syndrome has been reported rarely in children with an acute viral illness. Reye's syndrome has also been reported even more rarely in adults.
Withdrawal symptoms after abrupt cessation of carisoprodol have been reported and may be due to dependency on the meprobamate metabolite. Such symptoms include abdominal pain, agitation, tremor, restlessness, anxiety, depression, insomnia, nausea, and sweating. Seizures have been reported rarely.
Other side effects of codeine have included withdrawal symptoms. Withdrawal symptoms have been reported after either abrupt cessation or fast tapering of narcotic analgesics, and have included agitation, restlessness, anxiety, insomnia, tremor, abdominal cramps, blurred vision, vomiting, and sweating.[Ref]
Reye's syndrome typically involves vomiting, neurologic dysfunction, and hepatic dysfunction during or shortly after an acute viral infection.
Psychologic dependence and abuse of carisoprodol (often in combination with alcohol and other CNS depressants) have been reported.[Ref]
Hypotension is rare with codeine use and has been reported most frequently with high doses.[Ref]
Cardiovascular side effects of aspirin have been reported rarely and include salicylate-induced variant angina, ventricular ectopy, conduction abnormalities, and hypotension, particularly during salicylate toxicity.
Cardiovascular effects of carisoprodol have included tachycardia and hypotension.
Cardiovascular side effects of codeine have included hypotension and dizziness.[Ref]
Dermatologic side effects from the use of aspirin have been reported rarely and include Stevens-Johnson syndrome and a lichenoid eruption.
Codeine-induced rash have been reported rarely. Codeine-induced rashes may be related to direct stimulation of histamine release. Case reports of severe scarlatiniform eruptions have also been reported.[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]
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 which have included acute renal failure and urinary retention have been reported in association with codeine therapy.[Ref]
Hematologic side effects of aspirin (in addition to predictable antiplatelet effects which may result in hemorrhage) include increased blood fibrinolytic activity. In addition, hypoprothrombinemia, thrombocytopenia, thrombocyturia, megaloblastic anemia, and pancytopenia have been reported rarely. Aplastic anemia has also been reported.[Ref]
Hypersensitivity side effects include bronchospasm, rhinitis, conjunctivitis, urticaria, angioedema, and anaphylaxis with the use of aspirin. Approximately 10% to 30% of asthmatics are aspirin-sensitive (with the clinical triad of aspirin sensitivity, bronchial asthma, and nasal polyps).
Hypersensitivity effects of carisoprodol have included rash, pruritus, and erythema multiforme. Asthma, fever, hypotension and anaphylaxis have been reported rarely.[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]
Hepatic side effects including cases of aspirin-induced hepatoxicity and cholestatic hepatitis, particularly at high doses, have been reported rarely.[Ref]
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.[Ref]
Musculoskeletal side effects including rhabdomyolysis have occurred in patients receiving aspirin.[Ref]
Respiratory side effects including hyperpnea, pulmonary edema, and tachypnea have occurred in patients receiving aspirin.[Ref]
Endocrine side effects of aspirin use have been reported to include hypoglycemia (children) and hyperglycemia.[Ref]
In general, many of the side effects noted with aspirin use have been dose-related.[Ref]
Ocular side effects including cases of localized periorbital edema have been reported rarely in patients receiving aspirin.[Ref]
Oncologic side effects may be beneficial ones. Several epidemiologic studies have suggested that chronic aspirin use may decrease the risk of large bowel neoplasms. Other studies have not found such a beneficial effect.[Ref]
Immunologic side effects may occur. One study of a patient with exercise-induced anaphylaxis and three control subjects has found a correlation between codeine wheal size and recent exercise.[Ref]
