Side effects range from mild to severe
Kenalog (triamcinolone) is a prescription injection used to treat inflammation-related conditions. It belongs to the corticosteroid drug class. Side effects of Kenalog range from mild to severe.
Some of the mild side effects of Kenalog include acne, allergic dermatitis, fluid retention (edema), increased appetite, weight gain, and trouble sleeping. These side effects are usually temporary and often go away within a few hours to days. However, if the symptoms persist or become bothersome, it is recommended to consult a doctor or pharmacist for advice.

Some of the severe side effects, which are less common but can occur, include osteoporosis, joint damage, changes in mood or personality, eye problems such as cataracts and glaucoma, and increased risk of infections. Long-term use of Kenalog can lead to adrenal insufficiency, where the adrenal glands stop producing sufficient cortisol, also known as the stress hormone.
In rare instances, Kenalog can cause long-term side effects, and in some rare cases, it has been associated with the development of Kaposi's sarcoma, a type of cancer, in patients taking corticosteroids for extended periods. Additionally, Kenalog contains benzyl alcohol, which may cause serious reactions in newborn or premature infants, including hypotension and metabolic acidosis.
It is important to closely monitor any side effects while taking Kenalog and to consult a healthcare provider if any symptoms occur that are ongoing, bothersome, or potentially life-threatening.
