Health Canada has completed a safety review confirming that the use of nonsteroidal anti-inflammatory drugs (NSAIDs) starting from approximately 20 weeks of pregnancy or later may cause rare but serious kidney problems in an unborn baby. This can lead to low levels of amniotic fluid and possible complications, such as impaired lung maturation and limb contractures in the newborn baby. Health Canada is advising that pregnant women not use NSAIDs from approximately 20 to 28 weeks of pregnancy unless advised to do so by their health care provider. If a health care provider decides the use of NSAIDs between 20 and 28 weeks of pregnancy is necessary, Health Canada recommends that they use the lowest effective dose for the shortest duration possible and consider monitoring amniotic fluid levels via ultrasound if treatment extends beyond 48 hours. The use of NSAIDs remains contraindicated in the last trimester of pregnancy. The recommendations do not apply to the use of low-dose (81 mg) aspirin, pediatric-only formulations (those indicated only for children younger than 12 years), or ophthalmic formulations. Prescription and nonprescription NSAID product labels will be updated with this new information.

Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction (MI), and stroke, which can be fatal. This risk may occur early in the treatment and may increase with duration of use.
Celecoxib is contraindicated in the setting of coronary artery bypass graft (CABG) surgery.
NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events, including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at higher risk for serious GI events.
Note: Use the lowest effective dose for the shortest duration of time. Avoid or use with caution in patients at risk for or with existing cardiovascular disease, GI disease, kidney impairment, chronic liver disease, or a bleeding diathesis due to greater risk for adverse events. Consider administering in combination with a proton pump inhibitor in patients at risk for GI bleeding (eg, taking dual antiplatelet therapy or an anticoagulant, ≥60 years of age, high celecoxib doses) (ACCF/ACG/AHA [Abraham 2010]; ACCF/ACG/AHA [Bhatt 2008]).
Anti-inflammatory (eg, for arthritis associated with inflammatory rheumatic disease): Oral: Initial: 200 mg once daily or 100 mg twice daily; may increase to a maximum of 200 mg twice daily for several weeks during a disease flare until the flare resolves.
Dysmenorrhea: Oral: Initial: 400 mg, followed by an additional 200 mg approximately 12 hours later, if needed, on day 1; maintenance dose: 200 mg twice daily as needed; maximum daily maintenance dose: 400 mg/day. Begin at menses onset or 1 to 2 days prior to onset of menses for severe symptoms; usual duration: 1 to 5 days (Daniels 2009; Marjoribanks 2015; manufacturer's labeling).
Gout, treatment (acute flares) (off-label use):
Note: Some experts reserve use for patients who are not candidates for intra-articular glucocorticoids or when intra-articular glucocorticoid administration is not feasible (Gaffo 2022).
Oral: Initial: 400 mg, followed by 200 mg approximately 12 hours later on day 1, then continue 200 mg twice daily thereafter; maximum daily maintenance dose: 400 mg/day (Schumacher 2012; manufacturer's labeling). Begin within 24 to 48 hours of flare onset; discontinue 2 to 3 days after resolution of clinical signs; usual duration: 5 to 7 days (Gaffo 2022).
Osteoarthritis: Oral: 200 mg once daily or 100 mg twice daily.
Pain, acute (monotherapy or as an adjunctive agent): Oral: Initial: 400 mg, followed by 200 mg approximately 12 hours later, if needed, on day 1; thereafter, 200 mg twice daily as needed or scheduled; maximum daily maintenance dose: 400 mg/day (manufacturer's labeling). In select patients (eg, advanced age, comorbidity), some experts may initiate at 100 mg twice daily (Portenoy 2021).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Altered kidney function:
CrCl ≥60 mL/minute: No dosage adjustment necessary (<1% of the drug excreted in the urine) (Davies 2000; expert opinion).
CrCl >30 to <60 mL/minute: No dosage adjustment necessary (<1% of the drug excreted in the urine) (Davies 2000; expert opinion). However, use the lowest effective dose for the shortest duration possible. Use of analgesics other than nonsteroidal anti-inflammatory drugs (NSAIDs) or topical NSAIDs may be preferred. Avoid use in patients at high risk for acute kidney injury (ie, volume depleted, hypotensive, elderly, or taking concurrent nephrotoxic medications) (Baker 2020; KDIGO 2013; expert opinion).
CrCl ≤30 mL/minute: Avoid use due to increased risk of acute kidney injury (KDIGO 2013); Use of analgesics other than NSAIDs or topical NSAIDs are preferred. However, in select patients where alternatives are not effective, after careful assessment of risks versus benefits, use of celecoxib may be considered; use the lowest effective dose for the shortest duration possible with close monitoring of kidney function (expert opinion).
Hemodialysis, intermittent (thrice weekly): Unlikely to be significantly dialyzable (high protein binding, large Vd): Avoid use, as patients with end-stage kidney disease may be at increased risk for bleeding (eg, GI), cardiovascular adverse effects, and loss of residual kidney function (Kurella 2003; expert opinion). However, in select patients after careful assessment of risks versus benefits, use of celecoxib may be considered; use the lowest effective dose for the shortest duration possible (Koncicki 2017; expert opinion).
Peritoneal dialysis: Unlikely to be significantly dialyzable (high protein binding, large Vd): Avoid use, as patients with end-stage kidney disease may be at increased risk for bleeding (eg, GI), cardiovascular adverse effects, and loss of residual kidney function (Kurella 2003; expert opinion). However, in select patients after careful assessment of risks versus benefits, use of celecoxib may be considered; use the lowest effective dose for the shortest duration possible (Koncicki 2017; expert opinion).
CRRT: Avoid use (expert opinion).
PIRRT (eg, sustained, low-efficiency diafiltration): Avoid use (expert opinion).
Acute kidney injury while on celecoxib therapy: Discontinue use (expert opinion).
Mild impairment (Child-Pugh class A): No dosage adjustment necessary; AUC increased ~40% in mild hepatic impairment compared with healthy subjects.
Moderate impairment (Child-Pugh class B): Reduce dose by 50%.
Severe impairment (Child-Pugh class C): Use is not recommended.
Abnormal liver function tests (persistent or worsening): Discontinue use.
(For additional information see "Celecoxib: Pediatric drug information")
Juvenile idiopathic arthritis (JIA): Note: Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals.
Children ≥2 years and Adolescents:
≥10 kg to ≤25 kg: Oral: 50 mg twice daily
>25 kg: Oral: 100 mg twice daily
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Dosing adjustment in poor metabolizers of CYP2C9 substrates: Use with caution in patients who are known or suspected poor metabolizers of cytochrome P450 isoenzyme 2C9 substrates.
Children ≥2 years and Adolescents: Consider alternate therapy in JIA patients who are poor metabolizers; experience in adult patients suggests dosing adjustment.
Children ≥2 years and Adolescents:
Baseline:
Mild or moderate impairment: There are no dosage adjustments provided in the manufacturer's labeling; however, since <1% of the drug is excreted in the urine, dosage adjustment is not necessary (Davies 2000). Based on unpublished data, AUC was ~40% lower in adult patients with chronic renal insufficiency (GFR 35 to 60 mL/minute) compared with subjects with normal renal function due to a higher apparent clearance.
Severe impairment: Use is not recommended.
Advanced renal disease: Use is not recommended; however, if celecoxib treatment cannot be avoided, monitor renal function closely.
During therapy: Abnormal renal function tests (persistent or worsening): Discontinue use.
Children ≥2 years and Adolescents:
Moderate hepatic impatient (Child-Pugh Class B): Reduce dose by 50%; monitor closely
Severe hepatic impairment (Child-Pugh Class C): Use is not recommended; has not been studied
Initiate at the lowest recommended dose. The AUC in elderly patients (especially females and patients weighing <50 kg) may be increased by 50% compared with younger subjects.

Hypersensitivity to celecoxib, sulfonamides, aspirin, other NSAIDs, or any component of the formulation; patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs; use in the setting of CABG surgery.
Note: Although the FDA-approved product labeling states this medication is contraindicated in patients with hypersensitivity to sulfonamide-containing drugs, the scientific basis of this cross-sensitivity has been challenged. See “Warnings/Precautions” for more detail.
Canadian labeling: Additional contraindications (not in US labeling): Pregnancy (third trimester); women who are breast-feeding; severe, uncontrolled heart failure; active gastrointestinal ulcer (gastric, duodenal, peptic); active gastrointestinal bleeding; inflammatory bowel disease; cerebrovascular bleeding; severe liver impairment or active hepatic disease; severe renal impairment (CrCl <30 mL/minute) or deteriorating renal disease; known hyperkalemia; use in patients <18 years of age
Concerns related to adverse effects:
• Anaphylactoid reactions: Even in patients without prior exposure, anaphylactic reactions and angioedema may occur; patients with "aspirin triad" (bronchial asthma, aspirin intolerance, rhinitis) may be at increased risk. Contraindicated in patients who have experienced an anaphylactic reaction with nonsteroidal anti-inflammatory drugs (NSAIDs) or aspirin therapy.
• Cardiovascular events: [US Boxed Warning]: NSAIDs cause an increased risk of serious (and potentially fatal) adverse cardiovascular thrombotic events, including MI and stroke. Risk may occur early during treatment and may increase with duration of use. Relative risk appears to be similar in those with and without known cardiovascular disease or risk factors for cardiovascular disease; however, absolute incidence of cardiovascular events (which may occur early during treatment) was higher in patients with known cardiovascular disease or risk factors. New-onset hypertension or exacerbation of hypertension may occur (NSAIDs may also impair response to angiotensin-converting enzyme [ACE] inhibitors, thiazide diuretics, or loop diuretics) and contribute to cardiovascular events; monitor BP; use with caution in patients with hypertension. May cause sodium and fluid retention, use with caution in patients with edema. Avoid use in patients with heart failure (ACCF/AHA [Yancy 2013]). Avoid use in patients with recent MI unless benefits outweigh risk of cardiovascular thrombotic events. Long-term cardiovascular risk in children has not been evaluated. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of cardiovascular events; alternate therapies should be considered for patients at high risk.
• Drug reaction with eosinophilia and systemic symptoms: Potentially serious, sometimes fatal, drug reaction with eosinophilia and systemic symptoms (DRESS), also known as multiorgan hypersensitivity reactions, has been reported with NSAIDs. Monitor for signs and symptoms (eg, fever, rash, lymphadenopathy, eosinophilia) in association with other organ system involvement (eg, hepatitis, nephritis, hematological abnormalities, myocarditis, myositis). Early symptoms of hypersensitivity reaction (eg, lymphadenopathy, fever) may occur without rash; discontinue therapy and further evaluate if DRESS is suspected.
• GI events: [US Boxed Warning]: NSAIDs cause an increased risk of serious gastrointestinal inflammation, ulceration, bleeding, and perforation (may be fatal); elderly patients and patients with history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events. These events may occur at any time during therapy and without warning. Avoid use in patients with active GI bleeding. Use caution with a history of GI ulcers, concurrent therapy known to increase the risk of GI bleeding (eg, aspirin, anticoagulants and/or corticosteroids, selective serotonin reuptake inhibitors), smoking, use of alcohol, or in elderly or debilitated patients. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of GI adverse events; alternate therapies should be considered for patients at high risk. When used concomitantly with aspirin, a substantial increase in the risk of gastrointestinal complications (eg, ulcer) occurs; concomitant gastroprotective therapy (eg, proton pump inhibitors) is recommended (ACCF/ACG/AHA [Bhatt 2008]).
• Hematologic effects: Anemia may occur; monitor hemoglobin or hematocrit in patients on long-term treatment. Celecoxib does not usually affect PT, PTT or platelet counts; does not inhibit platelet aggregation at approved doses.
• Skin reactions: NSAIDs may cause serious skin adverse events, including exfoliative dermatitis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN); may occur without warning and in patients without prior known sulfa allergy; discontinue use at first sign of rash (or any other hypersensitivity).
• Sulfonamide ("sulfa") allergy: The FDA-approved product labeling for many medications containing a sulfonamide chemical group includes a broad contraindication in patients with a prior allergic reaction to sulfonamides. There is a potential for cross-reactivity between members of a specific class (eg, two antibiotic sulfonamides). However, concerns for cross-reactivity have previously extended to all compounds containing the sulfonamide structure (SO2NH2). An expanded understanding of allergic mechanisms indicates cross-reactivity between antibiotic sulfonamides and nonantibiotic sulfonamides may not occur or at the very least this potential is extremely low (Brackett 2004; Johnson 2005; Slatore 2004; Tornero 2004). In particular, mechanisms of cross-reaction due to antibody production (anaphylaxis) are unlikely to occur with nonantibiotic sulfonamides. T-cell-mediated (type IV) reactions (eg, maculopapular rash) are less well understood and it is not possible to completely exclude this potential based on current insights. In cases where prior reactions were severe (SJS/TEN), some clinicians choose to avoid exposure to these classes.
Disease-related concerns:
• Asthma: The manufacturer’s labeling states to not administer to patients with aspirin-sensitive asthma due to severe and potentially fatal bronchospasm that has been reported in such patients having received aspirin and the potential for cross reactivity with other NSAIDs. The manufacturer also states to use with caution in patients with other forms of asthma. However, in patients with known aspirin-exacerbated respiratory disease (AERD), the use of celecoxib initiated at a low dose with gradual titration in patients with stable, mild to moderate persistent asthma has been used without incident (Morales 2013).
• Bariatric surgery: Gastric ulceration: Avoid chronic use of oral nonselective NSAIDs after bariatric surgery; development of anastomotic ulcerations/perforations may occur (Bhangu 2014; Mechanick 2013). Short-term use of celecoxib or IV ketorolac are recommended as part of a multimodal pain management strategy for postoperative pain (Chou 2016; Horsley 2019; Thorell 2016).
• Coronary artery bypass graft surgery: [US Boxed Warning]: Celecoxib is contraindicated in the setting of coronary artery bypass graft surgery (CABG). Risk of MI and stroke may be increased with use following CABG surgery.
• Cytochrome P450 isoenzyme 2C9 deficiency: Use with caution in patients with known or suspected deficiency of cytochrome P450 isoenzyme 2C9 (CYP 2C9*3/*3); poor metabolizers may have higher plasma levels due to reduced metabolism; consider reduced initial doses (initiate therapy with 25% to 50% of the lowest starting dose [eg, 50% to 75% dose reduction]) (CPIC [Theken 2020]). Alternate therapies should be considered in patients with juvenile idiopathic arthritis (JIA) who are poor metabolizers of CYP2C9.
• Hepatic impairment: Use with caution in patients with moderate hepatic impairment; dosage adjustment recommended. Not recommended for patients with severe hepatic impairment. Transaminase elevations have been reported with use; closely monitor patients with any abnormal LFT. Rare (sometimes fatal), severe hepatic reactions (eg, fulminant hepatitis, hepatic necrosis, hepatic failure) have occurred with NSAID use; discontinue if signs or symptoms of liver disease develop, if systemic manifestations occur, or with persistent or worsening abnormal hepatic function tests.
• Renal impairment: NSAID use may compromise existing renal function. Dose-dependent decreases in prostaglandin synthesis may result from NSAID use, causing a reduction in renal blood flow which may cause renal decompensation (usually reversible). Patients with impaired renal function, dehydration, hypovolemia, heart failure, liver dysfunction, those taking diuretics, ACE inhibitors, angiotensin II receptor blockers, and the elderly are at greater risk for renal toxicity. Rehydrate patient before starting therapy; monitor renal function closely. Avoid use in patients with advanced renal disease; discontinue use with persistent or worsening abnormal renal function tests. Long-term NSAID use may result in renal papillary necrosis.
Special populations:
• Pediatric: Use with caution in pediatric patients with systemic-onset JIA; serious adverse reactions, including disseminated intravascular coagulation, may occur.
Consider alternate therapy in JIA patients who are identified to be CYP2C9 poor metabolizers. In a small pediatric study (n=4), the AUC of celecoxib was ~10 times higher in a child who was homozygous for CYP2C9*3, compared to children who were homozygous for the *1 allele (n=2) or who had the CYP2C9*1/*2 genotype; further studies are needed to determine if carriers of the CYP2C9*3 allele are at increased risk for cardiovascular toxicity or dose related adverse effects of celecoxib, especially with long-term, high-dose use of the drug (Stempak 2005). Long-term (>6 months) cardiovascular toxicity in children and adolescents has not been studied.

Nonsteroidal anti-inflammatory drugs (NSAIDs) may delay or prevent rupture of ovarian follicles. This may be associated with infertility that is reversible upon discontinuation of the medication. Consider discontinuing use in patients having difficulty conceiving or those undergoing investigation of fertility.
Based on available information, NSAIDs can be continued in males with rheumatic and musculoskeletal diseases who are planning to father a child (ACR [Sammaritano 2020]).
The use of nonsteroidal anti-inflammatory drugs (NSAIDs) close to conception may be associated with an increased risk of miscarriage due to cyclooxygenase-2 inhibition interfering with implantation (Bermas 2014; Bloor 2013).
Birth defects have been observed following in utero NSAID exposure in some studies; however, data are conflicting (Bloor 2013). Nonteratogenic effects, including prenatal constriction of the ductus arteriosus, persistent pulmonary hypertension of the newborn, oligohydramnios, necrotizing enterocolitis, renal dysfunction or failure, and intracranial hemorrhage have been observed in the fetus/neonate following in utero NSAID exposure (Bermas 2014; Bloor 2013). Maternal NSAID use may cause fetal renal dysfunction leading to oligohydramnios. Although rare, this may occur as early as 20 weeks' gestation and is more likely to occur with prolonged maternal use. Oligohydramnios may be reversible following discontinuation of the NSAID (Dathe 2019; FDA 2020). In addition, nonclosure of the ductus arteriosus postnatally may occur and be resistant to medical management (Bermas 2014; Bloor 2013).
Maternal use of NSAIDs should be avoided beginning at 20 weeks' gestation. If NSAID use is necessary between 20 and 30 weeks' gestation, limit use to the lowest effective dose and shortest duration possible; consider ultrasound monitoring of amniotic fluid if treatment extends beyond 48 hours and discontinue the NSAID if oligohydramnios is found (FDA 2020). Because NSAIDs may cause premature closure of the ductus arteriosus, product labeling for celecoxib specifically states use should be avoided starting at 30 weeks' gestation.
Based on available information, NSAIDs can be continued during the first 2 trimesters of pregnancy in patients with rheumatic and musculoskeletal diseases; use in the third trimester is not recommended (ACR [Sammaritano 2020]).
NSAIDs may be used as part of a multimodal approach to pain relief following cesarean delivery (ACOG 2019).
Celecoxib is present in breast milk.
The relative infant dose (RID) of celecoxib is 1.7% when calculated using the highest breast milk concentration located and compared to a weight-adjusted maternal dose of 200 mg/day.
In general, breastfeeding is considered acceptable when the RID of a medication is <10% (Anderson 2016; Ito 2000).
The RID of celecoxib was calculated using a milk concentration of 330 ng/mL, providing an estimated infant dose via breast milk of 0.05 mg/kg/day. This milk concentration was obtained following maternal administration of celecoxib 200 mg as a single oral dose to 6 postpartum women (Gardiner 2006). In 1 study, the half-life of celecoxib in breast milk was calculated to be 4 to 6.5 hours (Knoppert 2003). Peak breast milk concentrations occurred between 2 and 4 hours after the maternal dose (Gardner 2006; Hale 2004).
Adverse events were not observed in 2 breastfeeding infants 17 and 22 months of age (Hale 2004).
Nonopioid analgesics, including nonsteroidal anti-inflammatory drugs (NSAIDs), are preferred for breastfeeding patients who require pain control peripartum or for surgery outside of the postpartum period (ABM [Martin 2018]; ABM [Reece-Stremtan 2017]) and short-term use of celecoxib is considered acceptable (ABM [Reece-Stremtan 2017]). NSAIDs are considered compatible for the treatment of rheumatic and musculoskeletal diseases in lactating patients; agents with a short half-life and established safety data in infants may be preferred (ACR [Sammaritano 2020]).
According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and benefits of treatment to the mother. Maternal use of NSAIDs should be avoided if the breastfeeding infant has platelet dysfunction, thrombocytopenia, or a ductal-dependent cardiac lesion (ABM [Martin 2018]; ABM [Reece-Stremtan 2017]; Bloor 2013).
