Kenalog-40 (triamcinolone acetonide) is a corticosteroid indicated for intramuscular or intraarticular use only in allergic states, dermatologic diseases, endocrine disorders, gastrointestinal diseases, hematologic disorders, renal diseases, respiratory diseases, rheumatic disorders, and nervous system disorders where oral therapy is not feasible. Kenalog-40 is available as a generic drug. Side effects of Kenalog-40 include:

  • allergic reactions,
  • sleep problems (insomnia),
  • mood swings,
  • headache,
  • euphoria,
  • spinning sensation (vertigo),
  • dizziness,
  • nausea,
  • bloating,
  • appetite changes,
  • stomach or side pain,
  • stomach upset,
  • acne,
  • scaling or other skin changes,
  • a wound that is slow to heal,
  • thinning hair,
  • bruising or swelling,
  • sweating more than usual,
  • irregular menstrual periods,
  • redness or pain at the injection site, or
  • weight gain.

The usual suggested initial dose of Kenalog-40 is 60 mg, injected deeply into the gluteal muscle. Dosage is usually adjusted within the range of 40 mg to 80 mg, depending upon patient response and duration of relief. However, some patients may be well controlled on doses as low as 20 mg or less. Many doses are based on the patient's response to the medication and can be quite variable. Kenalog-40 may interact with birth control pills or hormone replacement therapy, blood thinners, cyclosporine, digoxin, insulin or oral diabetes medications, isoniazid, rifampin, seizure medications, antibiotics, aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs), or "live" vaccines. Tell your doctor all medications and supplements you use and all vaccines you recently received. Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Caution should be exercised when corticosteroids are administered to a nursing woman. There are no adequate and well-controlled studies in pregnant women. Corticosteroids like Kenalog-40 should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Infants born to mothers who have received corticosteroids during pregnancy should be carefully observed for signs of hypoadrenalism. Because of potential toxicity, Kenalog-40 use in pediatrics is cautioned.
