Opsta-D is a fixed-dose ophthalmic solution that combines levofloxacin (a broad-spectrum fluoroquinolone antibiotic) with dexamethasone (a corticosteroid). It is used to prevent and treat inflammation and bacterial infection of the eye, particularly in post-surgical settings (e.g., after cataract surgery). 

Yes — it is prescription-only . 

Combination anti-infective + anti-inflammatory ophthalmic agent (antibiotic + steroid). 

 Levofloxacin hemihydrate (typically ~ 5 mg/mL, i.e., 0.5%) 

– Dexamethasone sodium phosphate (typically ~ 1 mg/mL, i.e., 0.1%) 

– Preservative: Benzalkonium chloride (e.g., ~0.005%) in many formulations. 

Ophthalmic solution (eye-drop). Commonly in a 5 mL dropper bottle. 

Topical ocular use only (eye drops), not for ingestion.

Typical dosing: 1 drop into the conjunctival sac every 6 hours (i.e., 4 times daily) for ~7 days (depending on the indication). 

– Some regimens (especially post-surgery) may start more intensely, depending on the doctor’s instructions.

– Avoid touching the dropper tip to the eye or other surfaces to prevent contamination.

– Use for the full prescribed course; do not stop early without consulting your ophthalmologist.

Common Side Effects

Eye irritation, burning or stinging on application 

– Blurred vision temporarily, tearing, foreign-body sensation in eye 

– From steroid component: risk of increased intraocular pressure (IOP), possible glaucoma if used long term, risk of posterior subcapsular cataracts, corneal thinning or delayed healing in some cases. 

Typically a sterile plastic dropper bottle (often 5 mL) for ophthalmic solution. 

Storage Advice

Store at room temperature (check local label; often “store below 25–30 °C”) 

– Protect from light and moisture.

– Keep cap tightly closed when not in use.

– Discard bottle after a certain period once opened (as per local product insert).

Safety Advice

For external ocular use only.

– Do not use if you have a hypersensitivity to levofloxacin, dexamethasone, or any components of the formulation.

– Avoid in eyes with viral, fungal, or mycobacterial infections, because steroid may worsen such infections.

– Monitor intraocular pressure if used more than short-term.

– Long-term steroid use carries risk of glaucoma, cataracts, delayed wound healing, corneal thinning; use only under supervision.

– Avoid use in children (especially < 18) unless specifically indicated, due to lack of safety data in some cases.

– In pregnancy or breastfeeding: use only if benefit outweighs risk — discuss with your physician.

– Maintain good dropper hygiene to avoid contamination.

– If symptoms worsen (pain, vision changes, redness) or persist beyond recommended course, consult your ophthalmologist.

 Ducressa eye drops (levofloxacin + dexamethasone), a marketed equivalent. 

– Other antibiotic + steroid eye drop combinations, depending on local formulary (e.g., ofloxacin/dexamethasone, moxifloxacin/dexamethasone) — substitute only on medical advice.

According to Scab Pharmacy, the product is listed as Opsta-D. However, the exact manufacturer is not clearly disclosed on that listing. (No well-documented global brand “Opsta-D” found in major pharma databases.)

A very similar FDC is Ducressa by Santen (levofloxacin + dexamethasone).
