Description

Triamcinolone Inj. — Corticosteroid for Keloid & Scar Treatment

Triamcinolone Inj. is a corticosteroid injection manufactured by Shin Poong Pharmaceutical Co., Ltd. in Seoul, South Korea. Triamcinolone acetonide has been the standard intralesional treatment for keloid and hypertrophic scars since the 1960s. International clinical guidelines continue to recommend it as a first-line therapy.

Beyond scar treatment, triamcinolone is a versatile corticosteroid. Practitioners also use it for inflammation, allergic reactions, certain types of arthritis, and other conditions requiring anti-inflammatory therapy in patients who can’t take oral medication.

How Triamcinolone Works

As a corticosteroid, triamcinolone suppresses the inflammatory processes that drive excess collagen production in keloids and hypertrophic scars. It inhibits fibroblast activation and proliferation, decreases glycosaminoglycan production, and promotes the breakdown of existing excess collagen within the scar tissue.

This combination of effects targets scar formation from several angles at once. Because of this, triamcinolone reduces both the volume of the scar and the inflammation driving its continued growth. This is part of why it remains the most commonly recommended corticosteroid for this purpose, whether used alone or alongside other treatments like laser therapy or cryotherapy.

Who Triamcinolone Suits

Practitioners recommend Triamcinolone Inj. for patients interested in:

• Keloid scars, including those that continue growing beyond the original wound
• Hypertrophic scars with associated pain or itching
• Post-surgical or post-injury scarring requiring intervention
• Broader corticosteroid-responsive conditions, including inflammation and allergic reactions

Treatment Areas

Keloid and hypertrophic scars anywhere on the body, including post-surgical scars (such as after cesarean section) and facial or smaller lesions requiring lower-strength dosing

Dosage & Technique

Smaller or facial lesions typically use lower concentrations, around 2.5 to 5mg/mL. Larger or thicker keloids, on the other hand, call for higher-strength 40mg/mL preparations. A practitioner generally delivers about 0.1 to 0.2mL per square centimeter of affected skin using a fine needle, sometimes preceded by cryotherapy or local anesthetic to reduce discomfort. Most patients require multiple sessions, spaced every 4 to 6 weeks, over several months.

Precautions

• For use by licensed medical professionals only
• Korea’s MFDS has prohibited epidural use of triamcinolone specifically, following similar action by the US FDA — this restriction doesn’t apply to standard intralesional or intradermal use for scars
• Immediate hypersensitivity reactions are rare but have been reported; discuss any known steroid sensitivity before treatment
• Not recommended during pregnancy or breastfeeding without physician guidance
• Disclose any concurrent medications, particularly those affecting drug metabolism

Storage & Handling

• Store at room temperature, away from direct light
• Single-use only — do not reuse or resterilize
• For professional use only, by qualified and trained practitioners

Frequently Asked Questions

What is Triamcinolone Inj. used for?
Triamcinolone Inj. is most commonly used for keloid and hypertrophic scar treatment, and more broadly as a corticosteroid for inflammation, allergic reactions, and certain arthritic conditions.

How does triamcinolone treat keloid scars?
It suppresses inflammation, inhibits fibroblast activity, and reduces collagen accumulation, working to shrink scar tissue and ease associated pain and itching.

How many sessions are needed for scar treatment?
Most patients need multiple sessions spaced every 4 to 6 weeks, often extending over several months depending on scar size and response to treatment.

Is triamcinolone used for epidural injections?
No. Korea’s MFDS has prohibited epidural use of triamcinolone specifically, consistent with similar restrictions from the US FDA. This doesn’t affect its standard use for intralesional scar treatment.
