Corticosteroid — Intra-articular / Intramuscular Pregnancy: §4.6 VERBATIM: 'Pregnancy: The ability of corticosteroids to cross the placenta varies between individual drugs, however triamcinolone does cross the placenta. Administration of corticosteroids to pregnant animals can cause abnormalities of foetal development, including cleft palate, intra-uterine growth retardation and effects on brain growth and development. There is no evidence that corticosteroids result in an increased incidence of congenital abnormalities, such as cleft palate / lip in man. However, when administered for prolonged periods or repeatedly during pregnancy, corticosteroids may increase the risk of intra-uterine growth retardation. Hypoadrenalism may, in theory, occur in the neonate following prenatal exposure to corticosteroids but usually resolves spontaneously following birth and is rarely clinically important. As with all drugs, corticosteroids should only be prescribed when the benefits to the mother and child outweigh the risks. When corticosteroids are essential, however, patients with normal pregnancies may be treated as though they were in the non-gravid state. Breast-feeding: Corticosteroids may pass into breast milk, although no data are available for triamcinolone. Infants of mothers taking high doses of systemic corticosteroids for prolonged periods may have a degree of adrenal suppression.'

Triamcinolone Acetonide (Intra-articular)

Brand names: Kenalog, Adcortyl

This is intra-articular triamcinolone acetonide, a long-acting corticosteroid injected directly into a joint to relieve inflammation and pain in conditions such as osteoarthritis flares, rheumatoid arthritis, and other inflammatory arthropathies.

Adult dose

Dose: Intra-articular injection, and injection into tendon sheaths and bursae, using triamcinolone acetonide 10 mg/ml: 2.5–5 mg (0.25–0.5 ml) for smaller joints; 5–15 mg (0.5–1.5 ml) for larger joints. The dose depends on the size of the joint treated and the severity of the condition.
Route: Intra-articular injection, and injection into tendon sheaths and bursae. §4.2 verbatim: 'Adcortyl is for intra-articular or intra-dermal injection ONLY. The safety and efficacy of administration by other routes has yet to be established.' 'Strict aseptic precautions should be observed.'
Frequency: Not at fixed intervals — §4.2 verbatim: 'Since the duration of effect is variable, subsequent doses should be given when symptoms recur and not at set intervals.' (The '...may be repeated if necessary, at one or two week intervals' sentence in §4.2 sits inside the INTRADERMAL paragraph and is not stated for the intra-articular route.)
SCOPE — this is the page's PRIMARY route: intra-articular injection, which is exactly what the fetched UK SPC doses. ⚠️ THE INTRAMUSCULAR ROUTE THIS PAGE ALSO NAMES IS NOT COVERED. The fetched product is licensed for injection into joints and skin only — §4.2 verbatim: 'Adcortyl is for intra-articular or intra-dermal injection ONLY. The safety and efficacy of administration by other routes has yet to be established (see sections 4.3 and 4.4).' No intramuscular dose, and no PMR or RA bridging regimen, appears anywhere in this bundle; do not read the intra-articular figures below as an IM dose. The only UK SPC in this bundle is the 10 mg/ml presentation, whose intra-articular doses are 2.5–5 mg for smaller joints and 5–15 mg for larger joints. The SPC's own instruction is that subsequent doses are given when symptoms recur and not at set intervals. || §4.2 VERBATIM, the published figures: 'Adults: The dose of Adcortyl injection for intra-articular administration, and injection into tendon sheaths and bursae, is dependent on the size of the joint to be treated and on the severity of the condition. Doses of 2.5-5 mg (0.25-0.5 ml) for smaller joints and 5-15 mg (0.5-1.5 ml) for larger joints usually alleviate the symptoms. Triamcinolone acetonide 40 mg/ml (Kenalog) is available to facilitate administration of larger doses (see section 4.4 re Achilles tendon).' || ⚠️ STRENGTH GAP — THE 40 mg/ml PRODUCT IS NAMED BUT NOT DOSED. The sentence above is the only mention of Kenalog 40 mg/ml in the whole bundle; it states that the stronger product exists to allow larger doses but gives no figure for it, and the Kenalog SPC was not fetched. Every milligram figure published here therefore belongs to the 10 mg/ml presentation, and no number in this bundle supports a 40 mg intra-articular dose. Check the strength of the vial in your hand before drawing up. || MAX DOSE DELIBERATELY LEFT EMPTY. §4.2 states no maximum for the intra-articular route. The two caps that do appear — 'No more than 5 mg (0.5 ml) should be injected at any one site' and 'If several sites are injected the total dosage administered should not exceed 30 mg (3 ml)' — sit inside the INTRADERMAL paragraph ('Intradermal dosage is usually 2-3 mg (0.2-0.3 ml), depending on the size of the lesion. No more than 5 mg (0.5 ml) should be injected at any one site. If several sites are injected the total dosage administered should not exceed 30 mg (3 ml). The injection may be repeated if necessary, at one or two week intervals.'). They are a different route's ceiling, and a 5 mg per-site cap would directly contradict the 5–15 mg intra-articular dose for larger joints, so they are NOT carried into maxDose. || §4.4 INJECTION-SPECIFIC WARNINGS, verbatim: 'Corticosteroids should not be injected into unstable joints. Patients should be specifically warned to avoid over-use of joints in which symptomatic benefit has been obtained. Severe joint destruction with necrosis of bone may occur if repeated intra-articular injections are given over a long period of time. Care should be taken if injections are given into tendon sheaths to avoid injection into the tendon itself. Repeated injection into inflamed tendons should be avoided as it has been shown to cause tendon rupture. Due to the absence of a true tendon sheath, the Achilles tendon should not be injected with depot corticosteroids.' And: 'Intra-articular injection should not be carried out in the presence of active infection in or near joints. The preparation should not be used to alleviate joint pain arising from infectious states such as gonococcal or tubercular arthritis.' || §4.4 verbatim: 'Cases of serious anaphylactic reactions and anaphylactic shock, including death, have been reported in individuals receiving triamcinolone acetonide injection, regardless of the route of administration.' 'Several instances of blindness have been reported following injection of corticosteroid suspensions into the nasal turbinates and intralesional injection about the head.' || §4.4 verbatim, minimising systemic effect: 'Undesirable effects may be minimised using the lowest effective dose for the minimum period... Frequent patient review is required to titrate the dose appropriately against disease activity.' 'Adrenal cortical atrophy develops during prolonged therapy and may persist for years after stopping treatment. Withdrawal of corticosteroids after prolonged therapy must, therefore, always be gradual... During prolonged therapy any intercurrent illness, trauma or surgical procedure will require a temporary increase in dosage.' || ELDERLY, §4.2 verbatim: 'Treatment of elderly patients, particularly if long term, should be planned bearing in mind the more serious consequences of the common side effects of corticosteroids in old age, especially osteoporosis, diabetes, hypertension, hypokalaemia, susceptibility to infection and thinning of the skin. Close supervision is required to avoid life-threatening reactions.' || THE SECOND PROVIDER IN THIS BUNDLE IS THE WRONG ROUTE: the US 'Trilona' record is a topical corticosteroid label whose entire posology is 'Topical corticosteroids are generally applied to the affected area as a thin film two to four times daily for the 0.025% strength and two or three times daily for the 0.1% and 0.5% strength'. It contributes no injection dose and its skin-reaction profile is not the profile of an injected depot steroid. || ⚠️ §4.4 and §4.8 are truncated at the source-fetch limit — treat neither as complete.

Paediatric dose

Route: Intra-articular or intradermal injection
NO PER-KILOGRAM OR PER-SQUARE-METRE PAEDIATRIC FIGURE EXISTS IN THIS BUNDLE, so dosePerKg is null and the weight calculator is deliberately left unset. §4.2 VERBATIM, in full: 'Children: Adcortyl is not recommended in children under 6 years. Adcortyl intra-articular/intradermal may be used in older children in suitably adjusted dosages. Growth and development of children on prolonged corticosteroid therapy should be carefully observed. Caution should be used in the event of exposure to chickenpox, measles or other communicable diseases (see section 4.4).' The SPC gives no figure for what a 'suitably adjusted' dose is. || concentration is null because the bundle offers two different strengths and only one is sourced: the fetched SPC product is 10 mg/ml, while the 40 mg/ml (Kenalog) product it names was not fetched. Pinning a single number here would be a real mg-vs-ml hazard on a paediatric card. || Specialist paediatric rheumatology advice, and a children's formulary, should be used for any paediatric joint injection. || The SPC's own paediatric content is the under-6 restriction quoted above.

Dose adjustments

Renal

Not stated. No renal-impairment section was retrieved from the UK SPC in this bundle (§4.2 covers adults, elderly and children only), and the US provider is a topical label with no renal section. Do not infer an adjustment, and do not infer from the intra-articular route that none is needed — the SPC is explicit that depot corticosteroid injected into a joint is systemically absorbed (§4.4 describes adrenal cortical atrophy, hyperglycaemia and Cushingoid effects after injection).

Hepatic

Not stated. No hepatic-impairment section was retrieved from the UK SPC in this bundle, and the US provider is a topical label with no hepatic section. Do not infer an adjustment.

Dose independently re-sourced from UK Summary of Product Characteristics (SPC) via the eMC; US FDA prescribing information (openFDA / DailyMed) — cross-check; US labelling may differ from UK — clinician-reviewed. Always confirm against the product SmPC and your local formulary before prescribing.

During prolonged therapy any intercurrent illness, trauma or surgical procedure will require a temporary increase in dosage.'
  • §4.4 verbatim: 'Patients should carry Steroid Treatment Cards which give clear guidance on the precautions to be taken to minimise risk and which provide details of prescriber, drug, dosage and the duration of treatment. In addition, the patient should also carry a Steroid Emergency Card when multiple doses are given...' — the sentence is cut off by the source-fetch limit at this point.
  • §4.2 verbatim (elderly): 'Close supervision is required to avoid life-threatening reactions', bearing in mind osteoporosis, diabetes, hypertension, hypokalaemia, susceptibility to infection and thinning of the skin.
  • §4.4: warn the patient to avoid over-use of a joint that has become symptom-free after injection.
  • ⚠️ No laboratory monitoring schedule (e.g. blood glucose after injection) is specified anywhere in the fetched text, although §4.8 lists hyperglycaemia and inadequate control of diabetes mellitus as uncommon adverse reactions.

Clinical monograph

How it works

The glucocorticoid acts locally within the joint to suppress inflammatory cytokine release and immune cell activity, reducing synovial inflammation.

Prescribing in practice

  • Never inject into a joint suspected of being septic, and use strict aseptic technique, as intra-articular injection can introduce or mask joint infection.
  • Limit the frequency of injections into any single joint, as repeated steroid exposure may accelerate cartilage damage and joint deterioration.
  • A transient post-injection flare of pain can occur, and some systemic absorption may briefly affect glycaemic control in people with diabetes.

Monitoring

Monitor the injected joint for signs of infection, watch for post-injection flare, and check glycaemic control in people with diabetes after injection.

Counselling the patient

  • Rest the treated joint for a day or two after the injection.
  • Seek urgent advice if the joint becomes hot, swollen, or increasingly painful with fever.
  • If you have diabetes, monitor your blood sugars more closely for a few days.
