Triamcinolone acetonide (Kenalog) is a corticosteroid available by prescription as either an ointment, or in varying strengths of creams (USP 0.025%, 0.1%, 0.5%). Kenalog is applied topically, directly to the affected area of skin. Topical corticosteroids are synthetic steroids with anti-inflammatory and anti-pruritic properties. Kenalog has an FDA Category C pregnancy medication, which means that risk to a human fetus cannot be ruled out. Adequate, well-controlled human studies are lacking, and animal studies have shown a risk to the fetus or are lacking as well. There is a chance of fetal harm if the drug is administered during pregnancy; but the potential benefits may outweigh the potential risk. Notably, no common side effects have been reported with Kenalog Cream. However, severe adverse reactions have been reported, and can include severe allergic reactions (rash; hives; itching; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue); blurry vision; changes in menstrual cycle; easy bruising; excessive hair growth; impaired wound healing; itching, burning, redness, discoloration, or swelling of the skin not present before using Kenalog Cream; mental or mood changes; moon face; muscle weakness; rise in body temperature; skin thinning; tiredness. If you experience these consult your doctor immediately.
