Key points

  • Systemic and local dexamethasone formulations are not interchangeable.
  • Longer or intensive systemic treatment can suppress adrenal function and should not be stopped suddenly without a plan.
  • Severe infection symptoms, marked mood change, sudden vision loss or collapse needs urgent care.

What Dexamethasone is used for

Systemic dexamethasone has specialist uses in severe allergic states, cerebral oedema and other inflammatory conditions. Local formulations may be used for selected eye or ear inflammation, sometimes in combination products.

Important form differences

Systemic treatment affects the whole body. Eye and ear products act locally but can worsen some infections; combination ingredients must match the diagnosis.

Important safety checks

Active infection, diabetes, stomach-ulcer risk, severe mood disorder, osteoporosis, glaucoma, pregnancy and other steroids require review. Systemic treatment can mask infection and raise blood glucose. Follow clinician-directed tapering when adrenal suppression is possible.

When to seek urgent care

Seek urgent help for collapse, severe weakness with vomiting, fever with rapidly worsening illness, severe confusion or dangerous mood change, vomiting blood, black stools, sudden vision loss, severe eye pain or facial swelling with breathing difficulty.
