What should you know about oral triamcinolone acetonide?

Taken by mouth, this medicine can calm an overactive inflammatory or immune response throughout the body. It may be prescribed for selected inflammatory conditions when a clinician considers a systemic steroid appropriate. The dose and schedule depend on the condition, other medicines, and your health history; do not treat it as interchangeable with a steroid cream or an injection into the skin.

Possible effects include indigestion, mood or sleep changes, increased appetite, and difficulty controlling blood glucose. Longer or repeated courses can reduce the body's response to infection and may affect bones, eyes, blood pressure, or the adrenal system. Risk depends on the treatment plan, so the prescriber should know about diabetes, ulcers, glaucoma, osteoporosis, infections, and recent vaccines.

Take it exactly as prescribed and follow any instruction about food or timing. Do not stop a longer course suddenly unless the prescribing clinician gives you a tapering plan. Keep a list of medicines and supplements, including other steroids, and ask before starting a new treatment. A medical alert note can help another clinician understand that you use or recently used a corticosteroid.

The related material page for [Triamcinolone Acetonide](/materials/triamcinolone-acetonide/) explains the medicine itself, while [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/) covers a different route of treatment.

Seek urgent medical help for trouble breathing, swelling of the face or throat, severe confusion, fainting, black stools, vomiting blood, sudden vision changes, or a serious allergic reaction. Contact your prescriber promptly for fever, a worsening infection, severe abdominal pain, marked weakness, or major mood changes. If you have been taking it regularly and feel unwell after missing doses, ask for advice rather than making up the dose yourself.

Ask what condition the medicine is treating, how long the course is expected to last, whether the dose needs tapering, and which symptoms should trigger a call. Also ask how it fits with diabetes care, vaccines, surgery, pregnancy or breastfeeding, and any steroid cream, inhaler, or injection you use.
