Warnings & Precautions
Source: Lexicomp
Anaphylactoid reactions
Even in patients without prior exposure anaphylactoid reactions may occur; patients with "aspirin triad" (bronchial asthma, aspirin intolerance, rhinitis) may be at increased risk. Contraindicated in patients who experience bronchospasm, asthma, rhinitis, or urticaria with NSAID or aspirin therapy.
Cardiovascular events
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 serious cardiovascular thrombotic 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 ACE inhibitors, thiazide diuretics, or loop diuretics); may contribute to cardiovascular events; monitor blood pressure; 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. 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.
CNS effects
May cause drowsiness, dizziness, blurred vision, and other neurologic effects which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery or driving).
GI events
NSAIDs cause an increased risk of serious GI 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. In patients with a history of acute lower GI bleeding, avoid use of non-aspirin NSAIDs, especially if due to angioectasia or diverticulosis (Strate 2016). 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), advanced hepatic disease, coagulopathy, 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 GI complications (eg, ulcer) occurs; concomitant gastroprotective therapy (eg, proton pump inhibitors) is recommended (Bhatt 2008).
Hematologic effects
Platelet adhesion and aggregation may be decreased; may prolong bleeding time; patients with coagulation disorders or who are receiving anticoagulants should be monitored closely. Anemia may occur; patients on long-term NSAID therapy should be monitored for anemia. Rarely, NSAID use has been associated with potentially severe blood dyscrasias (eg, agranulocytosis, thrombocytopenia, aplastic anemia).
Hepatic effects
Transaminase elevations have been reported with use; closely monitor patients with any abnormal LFT. Rare (sometimes fatal) severe hepatic reactions (eg, fulminant hepatitis, liver necrosis, hepatic failure) have occurred with NSAID use; discontinue immediately if signs or symptoms of hepatic disease develop or if systemic manifestations occur.
Hyperkalemia
NSAID use may increase the risk of hyperkalemia, particularly in the elderly, diabetics, renal disease, and with concomitant use of other agents capable of inducing hyperkalemia (eg, angiotensin-converting enzyme [ACE] inhibitors). Monitor potassium closely.
Ophthalmic effects
Blurred and/or diminished vision has been reported; discontinue use and refer for ophthalmologic evaluation if such symptoms occur.
Renal effects
NSAID use may compromise existing renal function; dose-dependent decreases in prostaglandin synthesis may result from NSAID use, reducing renal blood flow, which may cause renal decompensation (usually reversible). Patients with impaired renal function, dehydration, hypovolemia, heart failure, hepatic impairment, those taking diuretics and ACE inhibitors or ARBs, and the elderly are at greater risk of renal toxicity. Rehydrate patient before starting therapy; monitor renal function closely. Long-term NSAID use may result in renal papillary necrosis and other renal injury.
Skin reactions
NSAIDs may cause potentially fatal serious skin adverse events including exfoliative dermatitis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN); may occur without warning; discontinue use at first appearance of skin rash (or any other sign of hypersensitivity). Disease-related concerns:
Asthma
Contraindicated in patients with aspirin-sensitive asthma; severe potentially fatal bronchospasm may occur. Use caution in patients with other forms of asthma.
Coronary artery bypass graft surgery
Use is contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Risk of MI and stroke may be increased with use within the first 10 to 14 days following CABG surgery.
Hepatic impairment
Use with caution in patients with hepatic impairment; patients with hepatic impairment may require reduced doses due to extensive hepatic metabolism. Patients with advanced hepatic disease are at an increased risk of GI bleeding with NSAIDs.
Renal impairment
Avoid use in patients with advanced renal disease unless benefits are expected to outweigh risk of worsening renal function; monitor closely if therapy must be initiated. Concurrent drug therapy issues:
Drug-drug interactions
Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information. Special populations:
Elderly
Elderly patients are at greater risk for serious GI, cardiovascular, and/or renal adverse events. Use with caution; initiate dose at the lower end of the dosing range. Dosage form specific issues:
Sorbitol
Oral suspension formulation may contain sorbitol. Concomitant use of sorbitol-containing products and sodium polystyrene sulfonate (Kayexalate) may cause intestinal necrosis (including fatal cases); combined use should be avoided. Other warnings/precautions:
Surgical/dental procedures
Withhold for at least 4 to 6 half-lives prior to surgical or dental procedures.
Pregnancy & Lactation
Pregnancy
Birth defects have been observed following in utero NSAID exposure in some studies; however, data is 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. In addition, non-closure of the ductus arteriosus postnatally may occur and be resistant to medical management (Bermas 2014; Bloor 2013). Because NSAIDs may cause premature closure of the ductus arteriosus, product labeling for meloxicam specifically states use should be avoided starting at 30-weeks gestation. Use of NSAIDs can be considered for the treatment of mild rheumatoid arthritis flares in pregnant women; however, use should be minimized or avoided early and late in pregnancy (Bermas 2014; Saavedra Salinas 2015). The chronic use of NSAIDs in wome
Lactation
It is not known if meloxicam is present in breast milk. In general, NSAIDs may be used in postpartum women who wish to breastfeed; however, agents other than meloxicam are preferred (Montgomery 2012) and use should be avoided in women breastfeeding infants with platelet dysfunction or thrombocytopenia (Bloor 2013; Sammaritano 2014). According to the manufacturer, the decision to continue or discontinue breastfeeding during therapy should consider the risk of infant exposure, the benefits of brea
Monitoring
| Efficacy | Pain and inflammation control (VAS/NRS scores, joint mobility, functional status); minimum effective dose |
|---|---|
| Toxicity | Blood pressure (raises BP, antagonises antihypertensives); renal function (SCr, eGFR — especially in elderly, heart failure, CKD, dehydrated); Hb/faecal occult blood (GI bleeding); LFTs; oedema |
| Clinical pearl | Use the lowest effective dose for the shortest duration. Consider co-prescribing a proton pump inhibitor if GI risk factors present. COX-2 selective agents reduce GI but not CV risk. |
| Counseling | Take with food or milk to reduce GI upset. Report black stools, blood in urine, or significant ankle swelling. Monitor blood pressure regularly if hypertensive. |
