Piroxicam Side Effects

Medically reviewed by Last updated on Apr 26, 2023.

Applies to piroxicam: oral capsule.


Oral route (Capsule)

NSAIDs cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use. Piroxicam is contraindicated in the setting of coronary artery bypass graft 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 greater risk for serious GI events.

Serious side effects of Piroxicam

Along with its needed effects, piroxicam may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

Check with your doctor immediately if any of the following side effects occur while taking piroxicam:

For Healthcare Professionals

Applies to piroxicam: compounding powder, oral capsule.


The most commonly reported adverse effects are abdominal pain/discomfort, flatulence, nausea, epigastric distress, constipation, diarrhea, dizziness, and headache.[Ref]


Evidence from observational studies have shown administration of doses greater than 20 mg orally per day increases the risk for gastrointestinal (GI) side effects. This drug may be associated with a high risk of GI toxicity relative to other nonsteroidal anti-inflammatory drugs (NSAIDs). About 1 in 5 patients who develop serious upper GI adverse events due to NSAID therapy are symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occur in approximately 1% of patients whom are treated for 3 to 6 months and in 2% to 4% of patients treated for 1 year.[Ref]

Common (1% to 10%): Anorexia, indigestion, abdominal pain/discomfort, constipation, diarrhea, dyspepsia, flatulence, gross bleeding/perforation, heartburn, nausea, gastric and duodenal ulcers, vomiting, epigastric distress

Uncommon (0.1% to 1%): Dry mouth, esophagitis, gastritis, glossitis, hematemesis, melena, rectal bleeding, stomatitis

Rare (0.01% to 0.1%): Colic, eructation, pancreatitis

Frequency not reported: Peptic ulceration, gastrointestinal hemorrhage[Ref]


Common (1% to 10%): Abnormal renal function

Uncommon (0.1% to 1%): Renal papillary necrosis, glomerulonephritis, interstitial nephritis, nephrotic syndrome, renal failure[Ref]

Renal toxicity while using piroxicam has occurred in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of NSAIDs may cause a dose dependent reduction in prostaglandin formation and secondarily, renal blood flow, which may precipitate overt renal decompensation.[Ref]


Common (1% to 10%): Elevated liver enzymes

Uncommon (0.1% to 1%): Hepatitis, jaundice

Rare (0.01% to 0.1%): Liver failure[Ref]

Significant elevations of the liver enzymes AST and ALT (about 3 or more times the upper limit of normal) have occurred in approximately 1% of patients in clinical trials with nonsteroidal anti-inflammatory drugs (NSAIDs). Borderline elevations have occurred in up to 15% of patients taking NSAIDs, including this drug.[Ref]


Clinical trials of several COX-2 selective and nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) of up to 3 years duration have shown an increased risk of serious and sometimes fatal cardiovascular thrombotic events, myocardial infarction, and stroke.[Ref]

Common (1% to 10%): Edema

Uncommon (0.1% to 1%): Congestive heart failure, hypertension, tachycardia, syncope

Rare (0.01% to 0.1%): Arrhythmia, exacerbation of angina, hypotension, myocardial infarction, palpitations, vasculitis, chest pain

Frequency not reported: Arterial thrombotic events[Ref]


Common (1% to 10%): Pruritus, rash

Uncommon (0.1% to 1%): Alopecia, bruising, desquamation, erythema, photosensitivity,

Rare (0.01% to 0.1%): Toxic epidermal necrosis, erythema multiforme, exfoliative dermatitis, onycholysis, Stevens - Johnson syndrome, urticaria, vesiculobullous reaction, ecchymosis, petechial rash

Frequency not reported: Non-thrombocytopenic purpura (Henoch-Schonlein)[Ref]

Observational studies suggest that piroxicam may be associated with a higher risk of severe cutaneous adverse reactions than other non-oxicam NSAIDs. There is an increased risk early in the course of therapy, with the majority of cases occurring within the first month.[Ref]


Common (1% to 10%): Anemia, prolonged bleeding time

Uncommon (0.1% to 1%): Eosinophilia, leukopenia, purpura, thrombocytopenia

Rare (0.01% to 0.1%): Agranulocytosis, hemolytic anemia, aplastic anemia, lymphadenopathy, pancytopenia

Frequency not reported: Decreased hemoglobin and hematocrit[Ref]


Rare (0.01% to 0.1%): Anaphylaxis, angioedema

Frequency not reported: Serum sickness[Ref]

A combination of dermatological/allergic signs and symptoms suggestive of serum sickness have occasionally occurred while using this drug. These include arthralgias, pruritus, fever, fatigue and rash (e.g., vesiculobullous reactions and exfoliative dermatitis).[Ref]


Common (1% to 10%): Elevated BUN, elevated serum creatinine, anorexia

Uncommon (0.1% to 1%): Weight changes, hyperkalemia, fluid retention

Rare (0.01% to 0.1%): Appetite changes, hyperglycemia, hypoglycemia[Ref]

Nervous system

Common (1% to 10%): Dizziness, headache, sedation

Uncommon (0.1% to 1%): Asthenia, drowsiness, malaise, paresthesia, somnolence, tremors, vertigo, amnesia

Rare (0.01% to 0.1%): Akathisia, convulsions, coma, meningitis

Postmarketing experience: Aseptic meningitis[Ref]


Uncommon (0.1% to 1%): Asthma, dyspnea, epistaxis

Rare (0.01% to 0.1%): Respiratory depression, pneumonia

Common (1% to 10%): Tinnitus, deafness

Uncommon (0.1% to 1%): Fever

Rare (0.01% to 0.1%): Death, hearing impairment, thirst[Ref]


Rare (0.01% to 0.1%): Female fertility decreased[Ref]


Uncommon (0.1% to 1%): Infections, sepsis

Rare (0.01% to 0.1%): Positive ANA, flu-like syndrome[Ref]


Uncommon (0.1% to 1%): Cystitis, dysuria, hematuria, oliguria, polyuria, proteinuria, urinary frequency, menorrhagia[Ref]


Rare (0.01% to 0.1%): Sweating[Ref]


Uncommon (0.1% to 1%): Blurred vision

Rare (0.01% to 0.1%): Conjunctivitis, swollen eyes[Ref]


Uncommon (0.1% to 1%): Anxiety, confusion, depression, dream abnormalities, personality changes

Rare (0.01% to 0.1%): Hallucinations, mood alterations, nervousness
