Maxidex (Dexamethasone)

Maxidex is a corticosteroid used to treat inflammatory conditions of the eye.

• Post‑operative ocular inflammation: reduces swelling and pain after eye surgery.
• Anterior uveitis: controls intra‑ocular inflammation and prevents tissue damage.
• Allergic conjunctivitis: alleviates redness, itching and swelling caused by allergens.
• Corneal graft rejection: suppresses immune response to improve graft survival.
• Ocular edema: decreases fluid accumulation in the anterior segment.

• Dexamethasone binds to intracellular glucocorticoid receptors, forming a complex that translocates to the nucleus and modulates gene transcription. This action inhibits the production of pro‑inflammatory cytokines, reduces leukocyte migration, and stabilises lysosomal membranes, leading to a marked decrease in ocular inflammation and edema.

Adverse reactions may occur with ocular dexamethasone use.

Common Side Effects

• Eye irritation or burning sensation.
• Blurred vision.
• Increased intra‑ocular pressure.
• Mild cataract formation with prolonged use.
• Temporary tearing.
• Conjunctival hyperemia.

Serious or Rare Side Effects

• Secondary ocular infection (bacterial, fungal, or viral).
• Glaucoma due to sustained pressure rise.
• Delayed wound healing after surgery.
• Systemic adrenal suppression with extensive use.
• Severe hypersensitivity reactions (e.g., angio‑edema).
• Corneal ulceration or melting.

Use Maxidex only under the supervision of an eye‑care professional and follow prescribed regimens.

• Monitor intra‑ocular pressure: regular checks are essential during therapy.
• Avoid in active ocular infections: steroids can worsen bacterial, fungal, or viral infections.
• Do not wear contact lenses: remove lenses while using the drops and until the eye is clear.
• Systemic steroid caution: inform the physician of any concurrent systemic corticosteroid therapy.
• Known hypersensitivity: discontinue if allergic reactions develop.
• Store at room temperature: keep in the original container, protect from light and moisture.

Dexamethasone eye drops can interact with other medications, affecting safety or efficacy.

Major Interactions (Avoid)

• Systemic CYP3A4 inhibitors (e.g., ketoconazole): may increase systemic steroid exposure.
• Concurrent ocular NSAIDs: heightened risk of corneal melting.
• Antiviral agents for herpetic eye disease: steroids may exacerbate viral replication.

Moderate Interactions (Monitor Closely)

• Other topical ocular steroids: additive intra‑ocular pressure effects.
• Systemic immunosuppressants: increased risk of infection.
• Antifungal eye drops: potential reduced antifungal efficacy.
