The facts about ibuprofen and COVID-19

To Our Medical Professional Community,
At GSK Consumer Healthcare, we understand your need to have the correct information to feel confident in your treatment decisions, and to address your patients’ questions and concerns. That’s why we are sharing these updates regarding ibuprofen and COVID-19.
The evolving discussion around ibuprofen use and the COVID-19 vaccines.
The appropriate use of antipyretics/analgesics, like Advil (ibuprofen), is recommended by public health authorities to help relieve symptoms that may be experienced following vaccination.1,2 This is consistent with the fact that in the COVID-19 vaccine studies, participants were allowed to use antipyretics/analgesics to treat symptoms.3-6
Following the availability of the COVID-19 vaccines in Canada, an article published on CBC News in February 2021 investigated whether pain relievers such as ibuprofen and acetaminophen should be avoided around the timing of vaccination and if they could blunt the effects of the vaccine.
There is limited clinical data on how antipyretics/analgesics affect the immune response to vaccines. What’s more, immune response can vary based on type of vaccine and other factors. However, the clinical trials conducted to prove the safety and efficacy of COVID-19 vaccines offer some insight. Study participants were allowed to use antipyretics/analgesics, like ibuprofen, to treat mild side effects after injection. This was the case in the Pfizer-BioNTech and Moderna clinical trials, which showed efficacy of over 94%,3,4 implying the use of antipyretics/analgesics, like ibuprofen, did not impact the immune response to the vaccine.
Health authorities and scientific professional societies in the US, Canada, and Europe, including the Centers for Disease Control and Prevention (CDC), came out with a strong and consistent recommendation that antipyretics/analgesics, such as ibuprofen (Advil) or acetaminophen, can be taken for pain or discomfort caused by the COVID-19 vaccine.1,2 Furthermore, NACI (National Advisory Committee on Immunization) also states that medications such as oral analgesics or antipyretics (e.g., ibuprofen or acetaminophen) may be considered for the management of adverse events (e.g., pain or fever), if they occur after vaccination7. People should carefully read and follow the instructions they receive at the time of COVID-19 vaccination.

Ibuprofen and COVID-19
The scientific consensus is clear. OTC ibuprofen/Advil remains safe to use as directed. The current scientific literature does not show that OTC ibuprofen/Advil makes COVID-19 health outcomes worse, and the world’s leading health authorities have confirmed there is no evidence to recommend that COVID-19 patients avoid antipyretics/analgesics, like Advil (ibuprofen).
We have been constantly monitoring and evaluating research papers published in a broad range of scientific or academic journals around the world.
Recent Research Publications (March–May 2021):
- Lancet Rheumatololgy, May 2021 – NSAID use is not associated with higher in-hospital mortality or increased severity of COVID-19. This prospective, multi-centre cohort study at 255 UK healthcare facilities included the largest number of patients admitted to hospital with COVID-19 to date (78,674) and found that those taking NSAIDs before admission had the same outcomes as those who did not. The researchers did not find any differences in mortality or disease severity, or in secondary outcomes including admission to critical care, use of ventilation, use of oxygen, or presence of acute kidney injury.8
- Arthritis Rheumatology, May 2021 – A propensity score-matched cohort study found that “no increase in the risk of suspected or confirmed COVID-19 or mortality was observed among patients with OA in a primary care setting who were prescribed NSAIDs as compared to those who received comparator drugs”. The cohort consisted of adult patients age ≥18 years with osteoarthritis (OA), where a total of 13,202 patients were prescribed NSAIDs and compared to 12,457 patients who were prescribed the comparator drugs (paracetamol and codeine or paracetamol and dihydrocodeine). The study concluded “these results are reassuring and suggest that in the absence of acute illness, NSAIDs can be safely prescribed during the ongoing pandemic.”9
- Annals of the Rheumatic Diseases, January 2021 – No overall increased risk of COVID-19 related death associated with current prescribed NSAID use. In two similarly designed studies, researchers studied prescribed NSAID users and non-users and “...found no evidence of a harmful effect of routinely prescribed NSAIDs on COVID-19 related death.” They separately evaluated a general population (Study 1) and population with rheumatoid arthritis or osteoarthritis (Study 2); NSAID users and non-users did not have a difference in risk for COVID-19 related deaths when adjusted for differences between them in the two study populations. The researchers concluded that “…people currently prescribed NSAIDs for their long-term conditions should continue their treatment as part of their routine care.”10
- PLOS Medicine, September 2020 — A Danish study concluded that there was no association between NSAID use up to 30 days before testing for COVID-19 and mortality within 30 days or adverse outcomes within 14 days, including hospitalization, ICU admission and ventilation, for COVID-19 patients, and that NSAIDs do not lead to more severe coronavirus disease11.
- American Journal of Therapeutics, July/August 2020–Researchers found no supporting evidence to discourage the use of ibuprofen although authors raised a concern regarding the safety of ibuprofen use because of its potential role in increasing ACE-2 receptor levels within the Renin–Angiotensin–Aldosterone system. However, available data from limited studies show administration of recombinant ACE2 improves lung damage caused by respiratory viruses, suggesting ibuprofen use may be beneficial in COVID-19 disease.12
- London School of Hygiene and Tropical Medicine, August 2020 — Authors found no evidence of a harmful effect of NSAIDs on COVID-19 related deaths. Risks from COVID-19 do not need to influence decisions about therapeutic use of NSAIDs13.
- Headache, July 2020–A study concluded that there is no specific evidence at this time against the use of NSAIDs in patients with or without COVID‐19. Authors recommend a patient should be assessed for any other chronic diseases, underlying or pre-existing illnesses or conditions (i.e., co-morbid medical conditions) that may limit the use of NSAIDs and recommend a discussion of risks and benefits with all patients prior to prescribing NSAIDs.14
- British Pharmacological Society, July 2020 — The authors noted that epidemiological studies have suggested potential benefits for NSAID use on reducing the risk of development of severe disease in COVID-19 patients while also raising warning for ibuprofen use in COVID-19 patients15.
- JAMA Network Open, July 2020 — Researchers found that the currently available data, including the primary endpoints in their study, do not seem to support strong recommendations against using NSAIDs in patients with viral pneumonia16.
- Clinical Infectious Disease, July 2020 — Authors of an observational study from South Korea, suggested that the harms associated with NSAID use may outweigh their benefits for patients with COVID-19 and therefore should be used with caution. Researchers looked only at patients hospitalized with COVID-19 who were prescribed prescription-strength, not OTC NSAIDs in the 7 days before and including their inpatient hospitalization, and it is unclear if the prescribed NSAIDs were part of their COVID-19 treatment courses or for one or more underlying serious health conditions17.
- Clinical Microbiology and Infection, June 2020 — A peer reviewed, retrospective cohort study of 403 patients with COVID-19 from Shamir Medical Centre, Israel concluded that in the studied cohort of COVID-19 patients, “ibuprofen use was not associated with worse clinical outcomes, compared with paracetamol (acetaminophen) or no antipyretic. In patients with fever, there was no difference in clinical outcomes between ibuprofen and paracetamol (acetaminophen) users”18.
When used as directed, ibuprofen can be used safely and effectively to relieve pain and reduce fever associated with COVID-19 based on general medical consensus.

“There is no scientific evidence that establishes a link between ibuprofen, or other non-steroidal anti-inflammatory drugs (NSAIDs), and the worsening of COVID-19 symptoms.” The Government of Canada is monitoring the situation closely, including reviewing new information and reports as they become available, and will take the appropriate action to help protect the health and safety of Canadians.19 When choosing a fever or pain relief medication for COVID-19, patients and healthcare professionals should consider all available treatment options, including acetaminophen and NSAIDs.19,20

"Based on currently available information,WHO does not recommend against the use of ibuprofen. We are also consulting with physicians treating COVID-19 patients and are not aware of reports of any negative effects of ibuprofen, beyond the usual known side effects that limit its use in certain populations. WHO is not aware of published clinical or population-based data on this topic" 21

The NIH COVID-19 Treatment Guidelines recommend the following for the use of NSAIDs in patients with COVID-1922:
- Persons with COVID-19 who are taking NSAIDs for a co-morbid condition should continue therapy as previously directed by their physician (AIII).
- The Panel recommends that there be no difference in the use of antipyretic strategies (e.g. with acetaminophen or NSAIDS) between patients with or without COVID-19 (AIII).

“There is insufficient evidence that NSAIDs negatively impact morbidity or mortality of COVID-19. Health Canada continues to recommend both ibuprofen and acetaminophen for treatment of fever due to COVID-19.”23

Guidance for COVID-19 in Children published on Mar 25, 2020 recommends that current data and best practice both support the use of either acetaminophen or ibuprofen for COVID-19 symptoms relief.24
The acute management of COVID-19 in paediatrics (spring 2021 update) outlines that “fever can be managed by administering either acetaminophen or ibuprofen. Early concerns about ibuprofen use increasing risk for COVID-19 morbidity and mortality are not supported by evidence.”25
A legacy of evidence-based safety26
Ibuprofen is a well-established medicine that when used as labeled is considered safe for fever reduction and providing pain relief.
- It has been used by millions of consumers across 40 countries for more than 3 decades
- It has been extensively studied and is strictly regulated to ensure its use complies with local healthcare authority requirements
- It has been used extensively to relieve some of the symptoms of influenza (pain and fever)
