Data synthesis: We extracted pain and adverse events outcomes from 36 systematic reviews that assessed the efficacy of paracetamol in 44 painful conditions. There is high quality evidence that paracetamol is not effective for relieving acute low back pain (MD, 0. Evidence regarding efficacy in other conditions Autologous Cultured Chondrocytes for Implantation (Carticel)- FDA of low or very low quality. Frequency of adverse events was generally similar for people receiving placebo or paracetamol, except that Autologous Cultured Chondrocytes for Implantation (Carticel)- FDA elevation of blood liver enzyme levels was more frequent during repeated administration of paracetamol cryobiology journal patients with spinal pain Autologous Cultured Chondrocytes for Implantation (Carticel)- FDA, 3.

Conclusions: For most conditions, evidence regarding the effectiveness of paracetamol is insufficient for drawing firm conclusions. Evidence for its efficacy in four conditions was moderate to strong, and there is strong evidence that paracetamol is not effective for reducing acute low back pain.

Investigations that evaluate more typical dosing regimens are required. Further, narrative reviews have included conflicting information, adding to uncertainty about its appropriate use.

Clinicians and patients need information about the efficacy and safety of paracetamol when deciding whether to use it. The aim of our umbrella systematic review was to provide a comprehensive overview of systematic reviews of the efficacy and safety of paracetamol as an analgesic in a range of painful conditions, particularly with respect to providing immediate relief.

We also included systematic reviews that could not identify any relevant RCTs, and we screened reference lists of published RCTs primaria systematic reviews for further relevant Autologous Cultured Chondrocytes for Implantation (Carticel)- FDA. We included systematic reviews that compared the analgesic effects of paracetamol and placebo (saline solution or sterile water) in people of any age with any painful condition, in which change in pain intensity was reported as an outcome in the source material.

We placed no restrictions on the dose, formulation (immediate release, modified release, capsule, tablet, oral suspension, intravenous solution), route of administration (intravenous, oral, rectal), regimen (single or multiple dose), or dosing frequency for paracetamol. If several reviews regarding a condition had been published, we selected the review that included the largest number of eligible studies.

We documented any notable differences in findings or conclusions between included and excluded reviews. Two reviewers (CAS, GF) independently extracted treatment effect and adverse events data. The primary outcome was the difference between the analgesic effects of paracetamol and placebo. If several instruments were used to measure pain, we extracted primary pain outcomes as defined in the included review.

Treatment effect estimates were extracted for immediate (less than two weeks), short (two weeks to less than six weeks), intermediate (six weeks to less than 12 months), and long term effects (12 months or more). Adverse events, if reported, were extracted as secondary outcomes. Two reviewers (CAS, GF) assessed confidence in effect estimates (quality of evidence) according to the Grading of Recommendations Assessment, Development and Evaluation criteria (GRADE) criteria.

We analysed data by medical condition. If a review reported individual trial results rather than a pooled treatment effect, we computed a pooled treatment effect (when possible) and provided a GRADE rating. As GRADE ratings can be applied differently (eg, review authors may apply one or two downgrades for each domain), we conducted sensitivity analyses to determine the impact of less rigorous application of GRADE criteria (maximum of one downgrade for each domain) to the primary outcome.

We excluded a review regarding patients who had undergone knee arthroplasty51 that drew very different conclusions to those of a review selected for our overview42 because it included more eligible trials. The 36 reviews described treatment with paracetamol of 44 painful conditions in adults and children (Box 2).

A comprehensive summary of the converted effect estimates is included in Supporting Information, table 6. Of the 32 reviews including RCT evidence, we provided GRADE ratings for the primary outcome in 26 and revised the GRADE ratings included in four reviews26,29,31,43 (Supporting Information, table roche u 411. Effect Privigen (Immune Globulin Intravenous)- Multum we calculated from original RCT publications or from data in the included reviews are summarised in Supporting Information, table 8.

As most systematic reviews assessed immediate term pain responses (a few hours to two weeks after administration), we discuss immediate term effects only. The two exceptions are osteoarthritis pain44 and rheumatoid arthritis,16 for which paracetamol was administered as part of a continuing course of treatment lasting a few days to several weeks or months.

Sustained release tablets for acute low back pain were specifically evaluated,28 but reported information on paracetamol formulation was otherwise limited. For two conditions, there is moderate quality evidence that paracetamol is more efficacious than placebo.

One systematic review28 found high quality evidence that oral paracetamol (up to 3. Very low quality evidence was deemed inconclusive, even if the effect estimate was statistically significant. The other systematic reviews found that frequency of any or serious adverse events were similar for paracetamol and placebo, but the evidence was generally of low biogen elementlar. High or moderate quality evidence that paracetamol (typically 0.

The effect sizes were modest, particularly for patients with knee or hip osteoarthritis or nags headache. The frequency of adverse events (any or serious) was similar for paracetamol and placebo, although transiently elevated blood levels of liver enzymes (three times the normal limit) were documented in patients with spinal pain or osteoarthritis treated with paracetamol.

Our review of systematic reviews provides greater clarity about the efficacy of paracetamol in conditions for which conflicting evidence has been reported. For some conditions, we identified several relevant systematic reviews. We found that evidence for the effectiveness of multiple or single dose paracetamol therapy after knee and hip arthroplasty is inconclusive. Evidence for the efficacy of paracetamol in most pain conditions is of low quality or inconclusive, and for the four conditions for which there is high or moderate quality evidence of efficacy, the benefits are small.

However, many trials evaluated single doses or short courses of paracetamol, unlike typical clinical practice, while others did not choose assessment time points that corresponded to the maximum blood concentration Autologous Cultured Chondrocytes for Implantation (Carticel)- FDA paracetamol.

The frequency of adverse events was similar for patients receiving paracetamol and placebo. Evidence regarding the safe Autologous Cultured Chondrocytes for Implantation (Carticel)- FDA of paracetamol use is inconclusive and based on low quality evidence from observational studies with significant risk of confounding.

We found low quality evidence for the benefits of paracetamol in conditions typically associated with severe pain, including renal colic and abdominal pain. One review found that the benefit of 1 g intravenous paracetamol for people with renal colic was similar to that of opioid analgesics or NSAIDs. Physicians should discuss the clinical importance of effect estimates with their patients, as it will depend upon their baseline health status, individual circumstances, cost, risk of harm, and dinutuximab beta of treatment.

We used a comprehensive search strategy, report quantitative estimates of treatment effects (including estimates for systematic reviews that did not report them), and determined the overall quality of evidence according to the GRADE criteria.
