What Is Kenalog? Uses, Dosage, and What You Need to Know in 2026

Kenalog is one of the most widely used injectable corticosteroids in the United States, yet many patients who receive it have questions about what exactly it is, why it works so well, and what to expect. This comprehensive guide covers everything patients need to know about Kenalog in 2026 — from its uses and dosage to safety information and how it differs from other steroids.

What Is Kenalog?

Kenalog is the brand name for triamcinolone acetonide, a synthetic corticosteroid manufactured by Bristol-Myers Squibb. It has been FDA-approved since 1965 and belongs to a class of drugs called glucocorticoids — hormones that powerfully reduce inflammation throughout the body. Unlike over-the-counter anti-inflammatory medications (like ibuprofen), Kenalog is a prescription-only drug that must be administered by a healthcare professional.

Kenalog comes in three injectable strengths (Kenalog-10, Kenalog-40, Kenalog-80) and topical formulations (creams, ointments, dental paste). The injectable forms are used in clinical settings; topical forms may be dispensed at pharmacies for home use.

What Does Kenalog Treat?

Kenalog is FDA-approved for a remarkably wide range of inflammatory and allergic conditions. It is also used off-label for several additional indications. Common uses include:

Joint conditions: Rheumatoid arthritis, osteoarthritis, acute gout flares, bursitis, tendinitis, epicondylitis (tennis/golfer's elbow)

Skin conditions: Eczema, atopic dermatitis, contact dermatitis, psoriasis plaques, lichen planus, alopecia areata, keloids, hypertrophic scars

Allergic and respiratory conditions: Severe seasonal allergies, asthma exacerbations, drug hypersensitivity reactions

Autoimmune and systemic conditions: Lupus, multiple sclerosis acute flares, inflammatory bowel disease, pemphigus, uveitis

Blood/immune disorders: Certain anemias, thrombocytopenic purpura

What Are the Different Forms of Kenalog?

Kenalog is available in multiple formulations:

Kenalog-10 (10 mg/mL): Used for intra-articular (joint) and intralesional (skin) injections only. NOT for intramuscular use.

Kenalog-40 (40 mg/mL): The most commonly used injectable form. Used for both intramuscular (IM) and intra-articular injections. Generic triamcinolone acetonide 40 mg/mL is available.

Kenalog-80 (80 mg/mL): Used for IM and intra-articular injections where higher doses are needed.

Topical cream/ointment (0.025%, 0.1%, 0.5%): Applied to the skin for eczema, dermatitis, and other inflammatory skin conditions.

Dental paste (0.1%): Applied to mouth ulcers and inflammatory lesions of the oral mucosa.

How Is Kenalog Injection Given?

Kenalog injection must be administered by a licensed healthcare professional. How it's given depends on the condition:

Intramuscular (IM): Injected into the gluteal muscle for systemic effects (allergies, MS flares, widespread inflammation). Typical dose: 40–80 mg. Effects can last 4–6+ weeks.

Intra-articular: Injected directly into a joint (knee, shoulder, hip, etc.) for arthritis, gout, or bursitis. Dose varies by joint size: 2.5–40 mg.

Intralesional: Injected directly into a skin lesion (keloid, alopecia patch, psoriasis plaque). Kenalog-10 is typically used. Dose: 1 mg per site, up to 30 mg/day.

Important: Kenalog injectable suspension should NEVER be given intravenously (IV) or intrathecally (into the spinal fluid). These routes can cause serious neurological events or death.

Is Kenalog a Controlled Substance?

No. Kenalog (triamcinolone acetonide) is not a controlled substance and has no DEA scheduling. It can be prescribed by any licensed prescriber and has no special federal prescription requirements beyond a standard written or electronic prescription.

Can I Self-Inject Kenalog at Home?

No. Kenalog injectable suspension is not intended for self-administration by patients. Intra-articular, intramuscular, and intralesional injections must be performed by trained healthcare professionals to ensure correct placement, sterile technique, and to monitor for immediate adverse reactions.
