Long-term follow-ups are still required to determine the efficacy of RFA. Although the outcome of RFA is currently considered satisfactory, there are potential concerns with this treatment, including local hemorrhage, hematoma formation, dysesthesias, thermal injury, and infection. Therefore, the use of RFA will hold less clinical value if there is a higher risk of adverse effects. Conger et al. Kim et al. Four RCTs reported adverse events, and no significant differences in terms of adverse events were found between the two groups that were the focus of this study. All adverse effects were mild, and no further treatment was required.

The results of the present study should be interpreted in light of the study limitations. First, the included studies and sample sizes were relatively small, which may affect the overall results. Second, the possibility of other confounding factors affecting the results could not be completely ruled out, such as the types of RFA and the characteristics and health of the patients. Third, the overall quality of evidence was moderate. Future high-quality research that explores the effects of RFA on larger samples is required to confirm the findings of this study.

Finally, publication bias that is derived from a literature review is limiting and difficult to avoid. RFA is efficacious and safe for reducing pain and improving knee function in patients with knee OA, without increasing the risk of adverse effects.

Like its ability to control pain, aspirin's ability to control fever is due to its action on the prostaglandin system through its irreversible inhibition of COX.

Aspirin is used as an anti-inflammatory agent for both acute and long-term inflammation , [92] as well as for treatment of inflammatory diseases, such as rheumatoid arthritis. Aspirin is an important part of the treatment of those who have had a heart attack. For people who have already had a heart attack or stroke, taking aspirin daily for two years prevented 1 in 50 from having a cardiovascular problem heart attack, stroke, or death , but also caused non-fatal bleeding problems to occur in 1 of people. In those with no previous history of heart disease, aspirin decreases the risk of a non-fatal myocardial infarction but increases the risk of bleeding and does not change the overall risk of death.

Aspirin appears to offer little benefit to those at lower risk of heart attack or stroke—for instance, those without a history of these events or with pre-existing disease. Complicating the use of aspirin for prevention is the phenomenon of aspirin resistance. After percutaneous coronary interventions PCIs , such as the placement of a coronary artery stent , a U. Agency for Healthcare Research and Quality guideline recommends that aspirin be taken indefinitely. This is called dual antiplatelet therapy DAPT. In , the systematic review and network meta-analysis from Khan et al. In conclusion, the optimal duration of DAPT after PCIs should be personalized after outweighing each patient's risks of ischemic events and risks of bleeding events with consideration of multiple patient-related and procedure-related factors.

Moreover, aspirin should be continued indefinitely after DAPT is complete. Aspirin is thought to reduce the overall risk of both getting cancer and dying from cancer. Some conclude the benefits are greater than the risks due to bleeding in those at average risk. A meta-analysis through found that aspirin reduces the risk of cancer of the colorectum, esophagus, and stomach. Aspirin, along with several other agents with anti-inflammatory properties, has been repurposed as an add-on treatment for depressive episodes in subjects with bipolar disorder in light of the possible role of inflammation in the pathogenesis of severe mental disorders.

There is no evidence that aspirin prevents dementia. Aspirin is a first-line treatment for the fever and joint-pain symptoms of acute rheumatic fever. The therapy often lasts for one to two weeks, and is rarely indicated for longer periods. After fever and pain have subsided, the aspirin is no longer necessary, since it does not decrease the incidence of heart complications and residual rheumatic heart disease. Along with rheumatic fever, Kawasaki disease remains one of the few indications for aspirin use in children [] in spite of a lack of high quality evidence for its effectiveness.

Low-dose aspirin supplementation has moderate benefits when used for prevention of pre-eclampsia. For some people, aspirin does not have as strong an effect on platelets as for others, an effect known as aspirin-resistance or insensitivity. Meta-analysis and systematic reviews have concluded that laboratory confirmed aspirin resistance confers increased rates of poorer outcomes in cardiovascular and neurovascular diseases. Some of these risk factors include obesity, advancing age, diabetes mellitus, dyslipidaemia and inflammatory diseases. Aspirin is sometimes used in veterinary medicine as an anticoagulant or to relieve pain associated with musculoskeletal inflammation or osteoarthritis. Aspirin should only be given to animals under the direct supervision of a veterinarian , as adverse effects—including gastrointestinal issues—are common.

An aspirin overdose in any species may result in salicylate poisoning , characterized by hemorrhaging, seizures, coma, and even death. Dogs are better able to tolerate aspirin than cats are. Adult aspirin tablets are produced in standardised sizes, which vary slightly from country to country, for example mg in Britain and mg or 5 grains in the United States. Smaller doses are based on these standards, e. The dose required for benefit appears to depend on a person's weight. In general, for adults, doses are taken four times a day for fever or arthritis, [] with doses near the maximal daily dose used historically for the treatment of rheumatic fever.

March recommendations from the USPSTF on the use of aspirin for the primary prevention of coronary heart disease encourage men aged 45—79 and women aged 55—79 to use aspirin when the potential benefit of a reduction in MI for men or stroke for women outweighs the potential harm of an increase in gastrointestinal hemorrhage. In children with Kawasaki disease, aspirin is taken at dosages based on body weight, initially four times a day for up to two weeks and then at a lower dose once daily for a further six to eight weeks. In October , the U. Food and Drug Administration FDA required the drug label to be updated for all nonsteroidal anti-inflammatory medications to describe the risk of kidney problems in unborn babies that result in low amniotic fluid.

Aspirin should not be taken by people who are allergic to ibuprofen or naproxen , [] [] or who have salicylate intolerance [] [] or a more generalized drug intolerance to NSAIDs, and caution should be exercised in those with asthma or NSAID-precipitated bronchospasm. Owing to its effect on the stomach lining, manufacturers recommend people with peptic ulcers , mild diabetes , or gastritis seek medical advice before using aspirin.

Aspirin should not be given to children or adolescents to control cold or influenza symptoms, as this has been linked with Reye's syndrome. Aspirin use has been shown to increase the risk of gastrointestinal bleeding. In addition to enteric coating, "buffering" is the other main method companies have used to try to mitigate the problem of gastrointestinal bleeding. Buffering agents are intended to work by preventing the aspirin from concentrating in the walls of the stomach, although the benefits of buffered aspirin are disputed. Almost any buffering agent used in antacids can be used; Bufferin, for example, uses magnesium oxide. Other preparations use calcium carbonate.

Taking it with vitamin C has been investigated as a method of protecting the stomach lining. Taking equal doses of vitamin C and aspirin may decrease the amount of stomach damage that occurs compared to taking aspirin alone. It is a widespread habit among eye specialists ophthalmologists to prescribe aspirin as an add-on medication for patients with retinal vein occlusion RVO , such as central retinal vein occlusion CRVO and branch retinal vein occlusion BRVO. The reason of this widespread use is the evidence of its proven effectiveness in major systemic venous thrombotic disorders, and it has been assumed that may be similarly beneficial in various types of retinal vein occlusion.

However, a large-scale investigation based on data of nearly patients showed "that aspirin or other antiplatelet aggregating agents or anticoagulants adversely influence the visual outcome in patients with CRVO and hemi-CRVO, without any evidence of protective or beneficial effect". Large doses of salicylate , a metabolite of aspirin, cause temporary tinnitus ringing in the ears based on experiments in rats, via the action on arachidonic acid and NMDA receptors cascade. Reye's syndrome, a rare but severe illness characterized by acute encephalopathy and fatty liver , can occur when children or adolescents are given aspirin for a fever or other illness or infection. From to , cases of Reye's syndrome in people younger than 18 were reported to the U.

Centers for Disease Control and Prevention. Salicylates were detectable in Food and Drug Administration now recommends aspirin or aspirin-containing products should not be given to anyone under the age of 12 who has a fever, [] and the UK National Health Service recommends children who are under 16 years of age should not take aspirin, unless it is on the advice of a doctor. For a small number of people, taking aspirin can result in symptoms including hives , swelling, and headache.

Aspirin can induce swelling of skin tissues in some people. In one study, angioedema appeared one to six hours after ingesting aspirin in some of the people. However, when the aspirin was taken alone, it did not cause angioedema in these people; the aspirin had been taken in combination with another NSAID-induced drug when angioedema appeared. Aspirin causes an increased risk of cerebral microbleeds having the appearance on MRI scans of 5 to 10 mm or smaller, hypointense dark holes patches.

A study of a group with a mean dosage of aspirin of mg per day estimated an average absolute risk increase in intracerebral hemorrhage ICH of 12 events per 10, persons. Aspirin and other NSAIDs can cause abnormally high blood levels of potassium by inducing a hyporeninemic hypoaldosteronic state via inhibition of prostaglandin synthesis; however, these agents do not typically cause hyperkalemia by themselves in the setting of normal renal function and euvolemic state.

Aspirin can cause prolonged bleeding after operations for up to 10 days. In one study, 30 of people having elective surgery required reoperations to control bleeding. Twenty had diffuse bleeding and 10 had bleeding from a site. Diffuse, but not discrete, bleeding was associated with the preoperative use of aspirin alone or in combination with other NSAIDS in 19 of the 20 diffuse bleeding people. Aspirin overdose can be acute or chronic. In acute poisoning, a single large dose is taken; in chronic poisoning, higher than normal doses are taken over a period of time. Salicylate is also produced as a result of exposure to bismuth subsalicylate , methyl salicylate , and sodium salicylate. Aspirin is known to interact with other drugs. For example, acetazolamide and ammonium chloride are known to enhance the intoxicating effect of salicylates, and alcohol also increases the gastrointestinal bleeding associated with these types of drugs.

Corticosteroids may also reduce the concentration of aspirin. In psychiatric research, aspirin has been investigated as an add-on treatment for different disorders in the context of drug repurposing strategies, considering the role of inflammation in the pathogenesis of severe mental illnesses. Aspirin has been repurposed as an add-on treatment for depressive episodes in subjects with bipolar disorder. Aspirin might weakly reduce the risk of breast cancer per a meta-analysis.
