Triamcinolone Dosing Guidelines
Triamcinolone dosing varies significantly by route of administration and clinical indication, ranging from 5-10 mg/mL for intralesional dermatologic injections to 40-60 mg for intra-articular injections, 110-220 mcg/day for intranasal use, and 400-800 mcg/day for inhaled asthma therapy.
Intralesional/Dermatologic Injections
Standard Dermatologic Conditions
- For nodular acne: Use triamcinolone acetonide 10 mg/mL, which may be diluted with sterile normal saline to 5 or 3.3 mg/mL 1
- For acne keloidalis: Use triamcinolone acetonide 10 mg/mL for inflammatory follicular lesions 1
- For hypertrophic scars and keloids: Use triamcinolone acetonide 40 mg/mL 1
- For psoriasis: Use triamcinolone acetonide up to 20 mg/mL every 3-4 weeks, with injection volume varying based on lesion size 1
- For nail psoriasis affecting the nail matrix: Use intralesional triamcinolone acetonide 5-10 mg/mL 1
Small Lesions and Palm Injections
- For smaller lesions or dermatologic conditions in the palm: Use triamcinolone acetonide 5-10 mg/mL, with 0.05-0.1 mL per injection site (translating to 0.25-1 mg per injection site) 1
- For alopecia areata: Use a concentration of 5-10 mg/mL with multiple injection sites 1
Administration Frequency
- For most dermatologic conditions: Administer every 3-4 weeks as needed 1
- Monitor for local adverse effects including skin atrophy, pigmentary changes, telangiectasias, and hypertrichosis, which are dose-dependent and typically occur with repeated injections at higher concentrations 1
Intra-articular Injections
Joint-Specific Dosing
- For acute gout involving 1-2 large joints: A single injection of 60 mg intramuscularly is often sufficient 2
- For shoulder pain (subacromial or glenohumeral): Use 40 mg of triamcinolone acetonide 1
- For juvenile idiopathic arthritis: Triamcinolone hexacetonide is the preferred agent for intra-articular glucocorticoid injections 1
Gastrointestinal Indications
Esophageal Strictures
- Dosing protocol: Inject 0.5 mL aliquots of triamcinolone 40 mg/mL into four quadrants immediately before bougie dilatation 1
- Administration technique: Use a 4 mm-long, 23-gauge needle and leave it in place for at least 1 minute to minimize leakage 1
- Frequency: Administer as needed based on symptom recurrence (typically lasts up to 1 year) 1
Intranasal Administration
Allergic Rhinitis
- Initial dosing: Use 110 to 220 mcg once daily, which reduces symptoms within the first day of administration 3
- Maintenance dosing: Once symptoms are controlled, reduce from 220 to 110 mcg/day without loss of effect 3
- The medication is not significantly absorbed systemically and does not suppress HPA axis function at therapeutic dosages 3
Inhaled Administration for Asthma
Mild-to-Moderate Asthma
- Standard dosing: Use 400 mcg twice daily (800 mcg/day total) 4, 5
- Therapeutic benefit is evident within 1 week and increases throughout treatment 5
- This dosing improves FEV1 by 17%, reduces albuterol use by 44%, and decreases asthma symptoms by 36-39% 4
Moderate Asthma (Uncontrolled on Beta-Agonists)
- Initial dosing: Use 400 mcg twice daily during run-in periods 2
- Maintenance dosing: May reduce to 200 mcg twice daily in combination with long-acting beta-agonists, though complete elimination of inhaled corticosteroids leads to significantly higher treatment failure rates (46.3% vs 13.7%) 2
Intramuscular Administration for Severe Asthma
Life-Threatening, Steroid-Dependent Asthma
- High-dose protocol: Administer 360 mg intramuscularly as a single injection or divided over the first three days 6, 7
- This regimen produces marked functional improvement, with peak expiratory flow rates rising 25-93% and response durations ranging from 3 to 24 months 6
- Compared to low-dose oral prednisone, this approach significantly reduces emergency room visits and hospitalizations (21 vs 0 emergency visits, 10 vs 0 hospitalizations) 7
- Important caveat: Steroidal side effects are more pronounced with this high-dose approach, including transient weakness and diabetes 6, 7
Critical Safety Considerations
Absolute Contraindications
- Avoid injection at sites of active infection (impetigo, herpes) 1
- Do not use in patients with previous hypersensitivity to triamcinolone 1
- Avoid large injections in patients with active tuberculosis or systemic fungal infections 1
Relative Contraindications and Monitoring
- Exercise caution in patients with uncontrolled diabetes, heart failure, or severe hypertension 1
- Be aware that repeated injections can suppress the hypothalamic-pituitary-adrenal axis 1
- Facial and intertriginous areas are at higher risk for developing adverse effects 1
Maximum Dosing Limits
- The maximum dose per injection site should not exceed 150 mg 1
