How is Kenalog-80 given?

Kenalog-80 is given through a needle and can be injected into different areas of the body: into a muscle, into the space around a joint or tendon, or into a lesion on the skin. A healthcare provider will give you this injection.

Common questions about triamcinolone

Where should you not use triamcinolone acetonide cream?
Do not use triamcinolone acetonide cream on your face, groin, genitals, under your breasts or in your armpits unless directed by your doctor. Use in these sensitive areas may cause skin thinning, acne, visible blood vessels, skin color changes or unwanted hair growth. Avoid applying it to the nipples while breastfeeding. Continue reading
Is triamcinolone acetonide an antifungal cream?
No, triamcinolone acetonide is not an antifungal cream. It is a prescription corticosteroid (steroid) that calms itching, redness and swelling from skin conditions like eczema and psoriasis. It does not kill fungus. Using it by itself on a fungal infection such as ringworm, athlete's foot or jock itch can make the infection spread and harder to diagnose. Continue reading
Is triamcinolone good for poison ivy?
Yes. Triamcinolone is a prescription steroid cream or ointment that can calm the itching, redness, and swelling of a poison ivy rash. It works best on small, mild-to-moderate rashes, especially when you start it early. It won't make the rash disappear overnight. If the rash covers a large part of your body or is on your face, hands, feet, or genitals, your doctor will usually prescribe oral steroid pills like prednisone instead. Continue reading
Clobetasol vs. triamcinolone - how do they compare?
Topical clobetasol (Clobex, Impoyz, generics) is considered a very high potency topical corticosteroid (“steroid”) used on the skin, while triamcinolone (Kenalog, Triderm, generics) is a medium-to-low potency medicine. These prescription products may be used to treat conditions such as eczema, dermatitis, psoriasis, skin allergies or rashes or serious insect bites. Continue reading
What are steroid injections (cortisone shots)?
Steroid injections (corticosteroid injections/cortisone shots) are injections given by a healthcare professional directly into joints or other areas of the body to relieve symptoms such as pain, inflammation, or restricted movement. They are commonly used to treat shoulder and other joint pain, tendonitis, bursitis, back pain, or arthritis or to manage conditions such as sciatica, inflammatory bowel disease, and skin conditions such as psoriasis. Examples include hydrocortisone, triamcinolone, and methylprednisolone. Continue reading
Halobetasol vs triamcinolone: Which steroid cream Is better?
Choosing the best topical corticosteroid depends on your skin condition, symptoms, and where the rash appears on your body. Factors like steroid strength, cost, insurance coverage, and safety also matter. Your doctor can recommend the most appropriate treatment after examining your skin and reviewing your symptoms.
