Kenalog® 40 (Triamcinolone acetonide) 40 mg/mL, 5 ampoules

What Is Kenalog 40 (Triamcinolone Acetonide) 40 mg/mL?

Kenalog 40 is a long-acting corticosteroid medication containing triamcinolone acetonide, a synthetic glucocorticoid with anti-inflammatory and immunosuppressive properties. Each 1 mL ampoule contains 40 mg of triamcinolone acetonide in an injectable suspension.

The package contains five ampoules, providing a total of 200 mg of the active ingredient.

Kenalog 40 is used to manage selected inflammatory, allergic, and autoimmune conditions when corticosteroid treatment is appropriate.

It works by reducing inflammatory responses and modifying immune system activity, helping relieve symptoms such as swelling, pain, stiffness, and irritation.

Depending on the condition being treated, the medication may be administered by deep intramuscular injection or injection into a joint or certain surrounding structures.

Its prolonged action allows therapeutic effects to continue beyond the time of administration.

What Is Kenalog 40 Used For?

Kenalog 40 is used in several medical specialties to control inflammation and symptoms associated with conditions that respond to corticosteroid therapy. Its applications depend on the injection route and the patient's clinical condition.

• Joint disorders: Relief of pain, swelling, and stiffness associated with rheumatoid arthritis and osteoarthritis with an inflammatory component.
• Soft tissue inflammation: Management of bursitis, epicondylitis, and tenosynovitis.
• Allergic conditions: Treatment of selected severe or persistent allergic disorders, including seasonal allergic rhinitis and bronchial asthma.
• Autoimmune disorders: Corticosteroid treatment for certain inflammatory connective tissue diseases, including systemic lupus erythematosus.
• Skin conditions: Management of selected severe inflammatory dermatological disorders.
• Other medical conditions: Specific endocrine, blood, kidney, respiratory, and gastrointestinal disorders requiring systemic corticosteroid therapy.

How Does Triamcinolone Acetonide Work?

Triamcinolone acetonide acts on glucocorticoid receptors to influence the body's inflammatory and immune responses. It reduces the activity of inflammatory substances and suppresses certain immune processes responsible for tissue swelling and irritation.

Kenalog 40 is formulated as a prolonged-action suspension. Its effects may persist for an extended period, although the duration varies according to the condition, administration route, and individual response. It is not intended for emergencies requiring immediate corticosteroid action.

How Is Kenalog 40 Administered?

Kenalog 40 is intended for administration by qualified healthcare professionals using appropriate sterile injection techniques. The approved routes described in the product instructions are deep intramuscular injection and injection into joints or certain associated structures.

The dosage and frequency depend on the medical condition, its severity, and the patient's response.

Repeat administration is assessed according to the return of symptoms rather than a fixed schedule.

Kenalog 40 must not be administered intravenously, subcutaneously, epidurally, intrathecally, or into the eye.

Incorrect administration can cause serious complications.

What Precautions Should Be Considered?

Corticosteroid treatment may increase susceptibility to infections, elevate blood glucose levels, affect blood pressure, and suppress normal adrenal function. Particular caution is necessary in patients with diabetes, osteoporosis, glaucoma, cardiovascular disorders, or active infections.

Kenalog 40 is contraindicated in children younger than six years and in patients with hypersensitivity to its ingredients. Use during pregnancy or breastfeeding requires careful assessment of potential benefits and risks.

Possible adverse effects include headache, injection-site reactions, fluid retention, mood changes, increased blood glucose, and changes in skin or muscle tissue. Serious allergic reactions and systemic corticosteroid complications can also occur.

How Should Kenalog 40 Be Stored?

Store Kenalog 40 between 8°C and 25°C (46.4°F and 77°F). Keep the ampoules upright, protect them from freezing, and store them out of children's reach. The stated shelf life is three years.

Do not use the medication after its expiration date.
