Maxidex®
dexamethasone ophthalmic suspension 0.1%
Clinical Snapshot
Dexamethasone is a potent corticosteroid with broad anti-inflammatory efficacy and good anterior chamber penetration. Maxidex (suspension) and dexamethasone sodium phosphate (solution) are used across a range of anterior segment inflammatory conditions.
Mechanism of Action
Dexamethasone is a synthetic glucocorticoid with high receptor binding affinity. It inhibits phospholipase A2 and suppresses the full inflammatory cascade. Good corneal penetration supports use in anterior segment disease.
Common Clinical Applications
- Anterior segment inflammation
- Postoperative inflammation
- Allergic and inflammatory conjunctivitis
- Uveitis (adjunctive or when prednisolone is unavailable)
Typical Dosing Principles
One to two drops four to six times daily initially, tapering based on clinical response. Shake well before use.
Dosing information is provided for educational purposes. Always consult current prescribing information for specific dosing protocols.
Important Precautions
- Significant IOP elevation risk — monitor IOP with any extended course.
- Posterior subcapsular cataract risk with prolonged use.
- Contraindicated in viral, fungal, and mycobacterial infections.
Clinical Pearls
- Good anterior chamber penetration makes dexamethasone appropriate for anterior segment inflammation.
- Available in combination products (e.g., with tobramycin) for combined anti-infective and anti-inflammatory use.
- IOP monitoring is essential — dexamethasone has a higher IOP-elevating potential than fluorometholone.
- Shake well before use; the suspension vehicle requires thorough mixing.
Commonly Associated Disease States
Select any disease state to explore its full entry in the Disease State Library.
Anterior Uveitis
HLA-B27 association is present in a significant proportion of cases; recurrent anterior uveitis warrants systemic evaluation for associated conditions including ankylosing spondylitis, reactive arthritis, and inflammatory bowel disease.
Allergic Conjunctivitis
Blepharitis
An extremely common condition that frequently coexists with dry eye disease and MGD; a significant contributor to chronic ocular surface symptoms and a risk factor for recurrent hordeola and chalazia.
