2020 American College of Rheumatology guideline gout flare management colchicine NSAID glucocorticoid
For an acute gout attack, the usual anti-inflammatory options are colchicine, an NSAID, or a corticosteroid. The best choice depends mainly on kidney function, stomach-ulcer/bleeding risk, heart failure, diabetes, blood pressure, and other medicines. The ACR gout guideline supports all three as first-line flare treatments.
With telmisartan + cilnidipine:
- Do not stop telmisartan or cilnidipine on your own. Neither is a typical cause of gout. In fact, thiazide-type diuretics such as hydrochlorothiazide are much more likely to raise uric acid.
- Be cautious with NSAIDs such as ibuprofen, naproxen, diclofenac, or indomethacin. Combined with telmisartan, NSAIDs can reduce kidney blood flow, raise potassium, blunt blood-pressure control, and increase acute kidney-injury risk, especially if the patient is older, dehydrated, has CKD, diabetes, heart failure, or also takes a diuretic. They should be clinician-directed, at the lowest effective dose and for the shortest duration.
- Colchicine may be a reasonable option if started early, but its dose must be adjusted or avoided with significant kidney/liver disease and with certain interacting drugs, particularly strong CYP3A4 or P-glycoprotein inhibitors such as clarithromycin, erythromycin, ketoconazole, ritonavir/cobicistat, ciclosporin, or verapamil/diltiazem.
- A short course of oral steroid or an injection into the affected joint is often preferred when NSAIDs are risky due to kidney disease or telmisartan-related renal concerns. Steroids can temporarily worsen blood pressure and glucose, so monitoring is needed.
Immediate practical steps
- Arrange a same-day medical review to confirm it is gout and choose treatment safely.
- Rest, elevate, and apply ice for 15-20 minutes at a time.
- Maintain normal hydration unless on a fluid restriction.
- Avoid alcohol, binge eating, and dehydration during the flare.
- If already on allopurinol/febuxostat, do not stop it during the flare unless the treating clinician says otherwise. If attacks are recurrent, discuss long-term urate-lowering treatment and a serum urate target below 6 mg/dL.
Seek urgent care today if there is fever, chills, feeling unwell, a very hot swollen joint with inability to bear weight, a new first-ever attack, severe kidney disease, or concern for infection. Septic arthritis can resemble gout and needs urgent exclusion.
If you share the patient’s age, kidney function or creatinine/eGFR, other medicines including any diuretic, and whether this is a confirmed prior gout diagnosis, I can outline the safer option to discuss with their clinician.

acute monoarthritis differential diagnosis septic arthritis gout CPPD guideline synovial fluid crystals
Differential diagnosis of an acute gout-like attack
An abrupt, very painful, red, hot, swollen joint is often gout, but septic arthritis must always be excluded first, particularly in a first episode or when the patient is systemically unwell.
| Condition | Clinical clues that may help distinguish it |
|---|---|
| Septic arthritis | Acute hot swollen joint, often with fever or malaise, marked movement pain, recent surgery/injection, skin infection, prosthetic joint, immunosuppression, diabetes, or IV drug use. It can coexist with gout crystals, so crystals do not exclude infection. |
| CPP crystal arthritis (pseudogout) | Can look nearly identical to gout. More often affects knee, wrist, shoulder, ankle, or elbow and is common in older adults. Synovial fluid shows positively birefringent rhomboid CPP crystals rather than negatively birefringent needle-shaped monosodium urate crystals. |
| Trauma / intra-articular fracture / hemarthrosis | Clear injury, anticoagulant use, bleeding disorder, or bloody aspirate. Consider occult fracture if focal bony tenderness. |
| Cellulitis, erysipelas, abscess | Skin and soft-tissue tenderness/redness extends beyond the joint; pain with passive joint movement may be less prominent. It can accompany or mimic a gout flare. |
| Tendon or bursal inflammation | Bursitis, especially olecranon or prepatellar, and tenosynovitis may be focal around rather than within the joint. Can be septic or crystal-related. |
| Reactive arthritis | Often follows gastrointestinal or genitourinary infection; may involve several lower-limb joints, enthesitis, conjunctivitis, urethritis, or skin lesions. |
| Psoriatic arthritis / peripheral spondyloarthritis | Psoriasis, nail pitting, dactylitis, enthesitis, inflammatory back pain, or recurrent asymmetric joint involvement. |
| Rheumatoid arthritis or palindromic rheumatism | Usually multiple joints, often symmetric small-joint disease, morning stiffness, and recurrent short-lived attacks in palindromic rheumatism. Early RA can occasionally present as monoarthritis. |
| Osteoarthritis flare / internal derangement | Mechanical pain, prior OA, meniscal injury, locking/catching; synovial fluid is usually non-inflammatory. |
| Basic calcium phosphate crystal arthritis | Acute inflammatory attacks, typically shoulder or knee, often in older patients; routine polarized microscopy may not identify these crystals. |
| Charcot joint, avascular necrosis, tumor | Less common. Consider with neuropathy, chronic progressive destruction, atypical imaging, or persistent symptoms. |
Key diagnostic approach
Joint aspiration is the best test when there is significant uncertainty or any possibility of infection. Send synovial fluid for:
- Cell count and differential
- Crystal analysis under polarized light microscopy
- Gram stain and bacterial culture
Gout is confirmed by needle-shaped, negatively birefringent monosodium urate crystals. Pseudogout shows rhomboid-shaped, positively birefringent CPP crystals. Even when urate crystals are found, culture is still needed if septic arthritis is possible, because infection can coexist. This is consistent with acute monoarthritis guidance and Harrison's Principles of Internal Medicine, p. 161.
Serum uric acid alone cannot diagnose gout. It may be normal during an acute attack, and an elevated level does not prove that the red swollen joint is gout.
Red flags: urgent same-day assessment
- Fever, rigors, hypotension, confusion, or appearing unwell
- First-ever hot swollen joint
- Inability to bear weight or severe pain on passive movement
- Prosthetic joint or recent joint surgery/injection
- Immunosuppression, diabetes, advanced kidney disease, or IV drug use
- Overlying wound, spreading redness, or suspected cellulitis
Textbook differential includes bacterial infection, trauma, sarcoidosis, and calcium pyrophosphate arthropathy, with reactive arthritis, rheumatoid arthritis, and psoriatic arthritis as additional mimics in some contexts. Gout and pseudogout can also produce high inflammatory markers and fever.
