01Purpose and principlesWhat the treatment does and how it fits into care.
Glucocorticoids alter transcription through the intracellular glucocorticoid receptor and produce rapid anti-inflammatory and immunosuppressive effects. They also reduce osteoblast function, increase bone resorption, raise glucose, retain sodium, redistribute fat, weaken muscle and skin, alter mood and suppress the hypothalamic-pituitary-adrenal axis. Benefit can appear within hours while cumulative harm grows with dose, duration, repeat courses and patient vulnerability.
The prescription must answer five questions: what inflammatory process is being treated, what organ or function is threatened, why glucocorticoid is needed now, what steroid-sparing treatment is starting, and when the dose will stop or taper. A vague instruction such as use as directed is unsafe. Use one named preparation and express any conversion carefully because anti-inflammatory potency and mineralocorticoid activity differ.
Doses are indication-specific. Prednisolone 5–10 mg once each morning may be used as a brief bridge in some inflammatory-arthritis plans, whereas immediately sight-threatening giant-cell arteritis or severe vasculitis requires a specialist high-dose pathway. Methylprednisolone 250–1000 mg intravenously daily for one to three days is reserved for selected organ-threatening disease; pulses are not routine flare therapy and demand infection, cardiovascular, glucose and psychiatric safeguards.
Adrenal suppression is not equivalent to Cushingoid appearance. NICE identifies prednisolone 5 mg daily or more for four weeks or longer as a dose that can produce tertiary adrenal insufficiency, but repeated evening dosing, potent preparations, drug interactions and combined inhaled, topical, injected or oral exposure modify risk. Patients need a steroid emergency card and clear sick-day rules; vomiting that prevents oral absorption is an emergency.
If adrenal crisis is suspected, treatment precedes confirmation. Give hydrocortisone 100 mg IV or IM immediately, restore circulating volume with isotonic saline, correct glucose and electrolytes, identify the precipitant and continue stress hydrocortisone, commonly 200 mg over 24 hours by infusion or 50 mg IV or IM every six hours, under acute and endocrine care. A pre-treatment cortisol can be stored if this does not delay therapy.
Tapering protects both disease control and adrenal recovery. Above physiological range, dose reduction is mainly limited by inflammatory relapse; near prednisolone 3–5 mg daily, endogenous cortisol recovery becomes central. Morning dosing supports circadian rhythm. Distinguish disease flare from glucocorticoid withdrawal syndrome and adrenal insufficiency using symptoms, examination, inflammatory disease markers and, when appropriate, an 8–9 am cortisol or Synacthen pathway directed by endocrinology.
Bone protection starts with exposure planning. Record previous fragility fracture, age, menopause, falls, smoking, alcohol, calcium intake and other secondary causes; calculate fracture risk and obtain DXA when it will refine management. NOGG recommends prompt bone-protective treatment in high-risk people starting glucocorticoids because fracture probability rises quickly. Adequate calcium, vitamin D, weight-bearing activity and falls reduction complement, but do not replace, anti-osteoporosis medicine when indicated.
Key points
- Glucocorticoids are a bridge or rescue treatment, not a substitute for diagnosis and disease-modifying therapy; record the indication, dose, duration, taper and review date at initiation.
- In rheumatoid arthritis, NICE permits short-term glucocorticoid bridging when starting a new conventional DMARD and short-term treatment for flares; continuing longer requires discussion of long-term complications and alternatives.
- Use the lowest effective dose for the shortest period. A disease-specific regimen takes precedence over an improvised standard dose, particularly in giant-cell arteritis, vasculitis and organ-threatening connective-tissue disease.
- Prednisolone 5 mg daily or more for four weeks or longer can suppress the hypothalamic-pituitary-adrenal axis; provide a steroid emergency card and sick-day guidance when risk criteria are met.
- Never stop a prolonged systemic course abruptly. Tapering is faster above physiological range and slower near prednisolone 3–5 mg daily, with endocrine assessment if withdrawal symptoms, adrenal features or uncertain recovery develops.
- Before and during treatment assess infection, vaccination, blood pressure, weight, glucose, mood, sleep, eyes and bone risk; prophylaxis is determined by dose, duration and comorbidity.
- Glucocorticoid-induced fracture risk starts early and is partly independent of bone-mineral density; begin fracture assessment promptly when long-term exposure is expected, not after the first fracture.
- Intra-articular injection requires secure anatomy, asepsis, consent, infection exclusion and a rehabilitation plan; it can still cause hyperglycaemia and transient adrenal suppression.
- A normal temperature or CRP does not reliably exclude infection during higher-dose steroid treatment. Investigate the patient, not the inflammatory marker.
- During vomiting, severe illness, surgery or trauma, patients at adrenal risk need stress-dose instructions and must carry enough information for emergency teams to act.
02Indications, selection and cautionsWho may benefit, who needs urgent treatment and important alternatives.
Reduced swelling, stiffness, inflammatory pain and organ activity within the anticipated time supports effectiveness but does not prove the original diagnosis.
Weight gain, facial rounding, proximal weakness, thin bruised skin, striae, hypertension and hyperglycaemia indicate cumulative exposure and need for steroid-sparing action.
Fatigue, anorexia, nausea, abdominal pain, postural dizziness, hypotension, hyponatraemia or hypoglycaemia during taper or illness suggests inadequate endogenous cortisol.
New functional decline, delirium, focal pain, breathlessness, dysuria or shingles may be the main infection signal because fever and inflammatory markers can be attenuated.
Insomnia and activation may precede mood lability, mania, psychosis, depression or suicidality, often after initiation or dose escalation.
Height loss, vertebral pain, low-trauma fracture, hip or groin pain, proximal muscle weakness and falls should prompt fracture or osteonecrosis assessment.
03Assessment before treatmentTests and checks that guide safe selection.
Read from the initial assessment onwards. Tests may run in parallel in urgent care; first-line, preferred, confirmatory, definitive and gold-standard labels appear only when the chapter explicitly states them.
- 01
First-line baseline risk inventoryFirst stepFirst line - Why
- Define infection, metabolic, skeletal, psychiatric, ocular and adrenal vulnerability before a planned systemic course.
- Interpretation and limitations
- Record previous steroid exposure across routes, diabetes, pressure, weight, fracture, mood, glaucoma, ulcer risk, vaccinations, pregnancy and concurrent immunosuppression; urgency determines which tests can precede treatment.
- 02
Blood pressure, weight and glucose - Why
- Create measurable baselines for common early toxicities.
- Interpretation and limitations
- Use HbA1c or capillary glucose according to urgency and diabetes risk; high-dose treatment may require same-day monitoring because postprandial hyperglycaemia can precede fasting change.
- 03
Fracture-risk assessment and DXA - Why
- Identify people who need immediate bone-protective treatment during expected long-term exposure.
- Interpretation and limitations
- Previous fragility fracture or high FRAX probability can justify treatment without waiting for DXA; glucocorticoid dose adjustments and vertebral assessment refine risk.
- 04
Infection and vaccination assessment - Why
- Find active infection and plan prevention before immunosuppression intensifies.
- Interpretation and limitations
- Use symptom- and exposure-directed TB, hepatitis, HIV or varicella testing and update indicated inactivated vaccines; investigate suspected infection urgently even with modest CRP.
- 05
Morning cortisol or Synacthen testing - Why
- Assess recovery when a patient has tapered to a physiological range and safe withdrawal remains uncertain.
- Interpretation and limitations
- Do not delay adrenal-crisis treatment for testing. Interpretation depends on assay, timing and recent glucocorticoid; involve endocrinology for equivocal results or persistent symptoms.
- 06
Joint aspiration before local injection - Why
- Exclude septic or crystal arthritis when an effusion is hot, acute or diagnostically uncertain.
- Interpretation and limitations
- Send cell count, Gram stain, culture and crystal analysis; visible crystals do not exclude infection, and injection should wait when sepsis remains plausible.
- 07
Ophthalmic assessment - Why
- Investigate symptoms or prolonged exposure that raises cataract, glaucoma or ocular-infection concern.
- Interpretation and limitations
- Acute visual symptoms require urgent eye assessment; routine interval follows dose, duration, diabetes, previous pressure and ophthalmology advice.
04Treatment approachPreparation, options, escalation and aftercare.
01First prescribing stepDefine bridge, rescue and exitFirst stepActive inflammatory disease requires rapid control and glucocorticoid benefit is judged to outweigh immediate risk.+
- 1Name the diagnosis and target, exclude important infection, reconcile all steroid routes and document a baseline toxicity profile.
- 2Select the disease-specific preparation, dose, route and duration, and start or optimise the steroid-sparing treatment that will maintain control.
- 3Issue written taper or stop instructions, review date, sick-day advice and a steroid emergency card when adrenal-risk criteria are met.
02Risk-reduction bundlePrevent predictable cumulative harmTreatment will be repeated, exceed several weeks or use a dose likely to cause substantial immunosuppression.+
- 1Assess fracture probability promptly and start calcium, vitamin D and anti-osteoporosis treatment where indicated without delaying for a scan in clearly high-risk patients.
- 2Monitor pressure, weight and glucose, address infection and vaccine status, and screen mood, sleep, eyes and myopathy according to exposure.
- 3EscalationReview the dose at every encounter and make failure to taper a trigger to reconsider diagnosis, adherence, DMARD efficacy and specialist escalation.
03Taper and adrenal recoverySlow near physiological replacementDisease control permits dose reduction after a course long enough to suppress the adrenal axis.+
- 1Reduce more quickly while the dose remains clearly supraphysiological if the disease allows, then use smaller decrements near prednisolone 3–5 mg daily.
- 2Separate inflammatory relapse, withdrawal symptoms and adrenal insufficiency through timing, disease-specific findings, blood pressure, sodium and glucose.
- 3Use morning cortisol or dynamic testing under an endocrine pathway when recovery is uncertain; maintain emergency cover until competence is established.
04Adrenal emergencyTreat before the laboratory resultSevere illness, surgery, vomiting or steroid interruption produces collapse or features compatible with adrenal crisis.+
- 1Give hydrocortisone 100 mg IV or IM immediately and rapid isotonic saline, adding dextrose when hypoglycaemia is present.
- 2Continue hydrocortisone 200 mg over 24 hours or 50 mg every six hours, treat infection or other precipitant and monitor electrolytes, glucose and haemodynamics.
- 3After stabilisation, involve endocrinology for step-down, replacement, sick-day education and prevention of another missed-dose event.
05Local injection routeConfirm target and exclude infectionOne joint, bursa or tendon sheath remains symptomatic and an injection is clinically justified.+
- 1Confirm anatomy and diagnosis, check anticoagulation and diabetes, aspirate when sepsis or crystal disease is plausible and obtain informed consent.
- 2Use aseptic technique and an anatomical dose appropriate to the licensed product, avoiding tendon substance and repeated unscheduled injections.
- 3Give a graded post-injection activity plan and urgent safety-net for increasing pain, swelling, fever, neurological change or marked glucose disturbance.
05Regimens, contraindications and interactionsTreatment details and the circumstances that modify them.
Prednisolone
For a selected inflammatory-arthritis bridge, a common specialist regimen is 5–10 mg orally once each morning for the shortest feasible period with an explicit taper; organ-threatening diseases use diagnosis-specific higher regimens and must not be inferred from this example.Screen infection and monitor glucose, blood pressure, mood, eyes and bone. Courses causing adrenal suppression require taper, emergency card and sick-day cover; avoid abrupt withdrawal.
Methylprednisolone intravenous pulse
For selected organ-threatening autoimmune disease, specialist protocols use 250–1000 mg intravenously once daily for one to three days, followed by a diagnosis-specific oral and steroid-sparing plan.Exclude or treat infection, monitor rhythm, pressure, glucose, electrolytes, psychiatric effects and fluid status; the regimen is specialist-directed and not routine musculoskeletal flare treatment.
Hydrocortisone for adrenal crisis
Administer hydrocortisone 100 mg IV or IM without delay; continue 200 mg across each 24 hours by infusion, or 50 mg IV or IM every six hours, while acute illness persists.Do not await cortisol results. Give isotonic fluid, treat hypoglycaemia and the precipitant, and seek endocrine guidance for subsequent taper to replacement dosing.
Triamcinolone acetonide intra-articular injection
Use a product- and joint-specific dose; a common licensed range is 5–10 mg for small joints and up to 40 mg for a large joint, given once with repetition determined by response and specialist policy.Use asepsis, avoid tendon substance and unstable joints, and counsel on post-injection flare, infection, skin or fat atrophy, transient hyperglycaemia and systemic adrenal exposure.
Alendronic acid
When oral bisphosphonate treatment is indicated, give 70 mg orally once weekly on an empty stomach with plain water, remaining upright and taking no food, drink or other medicine for at least 30 minutes.Check renal function, calcium and vitamin D, swallowing or oesophageal disease and dental context; do not use in hypocalcaemia or if administration precautions cannot be followed.
06Complications, monitoring and follow-upAdverse effects, response and longer-term review.
- At every review record current and cumulative dose, flare control, the intended next reduction and whether the steroid-sparing treatment is working; unexplained dose persistence requires a new plan.
- Monitor weight, blood pressure and glucose early after initiation or dose escalation and at intervals determined by dose, duration and diabetes or cardiovascular risk.
- Ask directly about infection, shingles, sleep, mood, psychosis, weakness, falls, bruising, visual symptoms and gastrointestinal bleeding because laboratory surveillance alone misses major toxicity.
- Reassess fracture risk, adherence to bone protection, calcium and vitamin D status and new back or hip pain; repeat DXA according to risk and osteoporosis guidance rather than annually by default.
- Verify that patients at adrenal risk hold a current steroid emergency card, understand sick-day dose escalation, possess adequate tablets and know that vomiting or collapse needs injectable treatment.
- After an intra-articular injection, document clinical response and adverse effects before considering another; repeated failure should reopen diagnosis and rehabilitation rather than shorten the interval automatically.
07Special situationsVariants, exceptions and circumstances that change the usual approach.
Morning dosing respects physiology
Giving once-daily prednisolone in the morning generally reduces sleep disturbance and aligns exposure more closely with the normal cortisol rhythm.
Inflammation and adrenal symptoms overlap
Fatigue, pain and malaise during taper can represent disease relapse, withdrawal or cortisol deficiency, so a reflex dose increase can perpetuate harm.
Fractures occur before low BMD is obvious
Glucocorticoids impair bone quality and raise falls risk, meaning bone-mineral density alone underestimates early fracture probability.
Injection is systemic exposure
A local depot can transiently suppress the adrenal axis and raise glucose, especially after multiple sites or concurrent steroid routes.
Normal CRP can be false reassurance
Immunosuppression may attenuate inflammatory markers and fever; focal symptoms, physiology and cultures determine whether infection remains credible.
Stress dosing is replacement, not flare therapy
Extra hydrocortisone during severe illness prevents cortisol failure and should not be confused with escalation for rheumatic inflammation.
08Common pitfallsFrequent interpretation and management errors.
- 01
Starting prednisolone without recording a diagnosis, duration, taper, review date and the disease-modifying treatment expected to replace it.
- 02
Stopping a prolonged course abruptly because inflammatory symptoms are quiet while overlooking adrenal suppression.
- 03
Waiting for a cortisol result before treating a patient with shock and credible adrenal crisis.
- 04
Delaying bone-risk assessment until three months have elapsed even though fracture risk rises early after glucocorticoid initiation.
- 05
Calling an afebrile patient infection-free despite new focal symptoms during higher-dose or combined immunosuppression.
- 06
Injecting a hot swollen joint before aspiration or repeating local steroid when the anatomy, diagnosis and rehabilitation plan remain uncertain.
