Acular is an ophthalmic solution that contains the active ingredient ketorolac trometamol. It belongs to the eye-care therapeutic class and is formulated as a clear, sterile 0.4 % solution packaged in a single-use bottle. In Hong Kong, Acular is available by prescription and is marketed for the temporary relief of ocular itching associated with seasonal allergic conjunctivitis, as well as for the control of inflammation and pain following certain eye surgeries. The same active ingredient is also supplied as a generic ketorolac ophthalmic solution.
Ketorolac trometamol is a non-steroidal anti-inflammatory drug (NSAID). When administered as eye drops, it:
The drug’s local action provides rapid symptom relief while minimizing systemic exposure. Effects typically begin within minutes, peak within an hour, and can last several hours after each dose.
These indications are approved by Hong Kong’s Department of Health and are supported by clinical studies that demonstrate the efficacy of topical ketorolac in reducing ocular inflammation and pruritus.
These effects are usually brief and resolve without intervention.
If any serious symptom occurs, discontinue the drops and seek ophthalmic care promptly.

Acular is formulated specifically for allergic conjunctivitis and postoperative inflammation. Using it for other types of eye irritation is considered off-label and should only be done after an eye-care professional evaluates the underlying cause.
A standard 5 mL bottle containing a 0.4 % solution provides approximately 100 drops. At the recommended dose of one drop twice daily, one bottle can last about 50 days, assuming proper storage and no waste.
Because the medication is applied topically to the eye, systemic absorption is minimal. Systemic side effects commonly associated with oral NSAIDs are therefore unlikely, though rare systemic reactions can occur in highly sensitive individuals.
It is advisable to remove contact lenses before instilling the drops and wait at least 15 minutes before reinserting them. This helps avoid dilution of the medication and reduces the chance of lens contamination.
Mild burning usually resolves within a few minutes. If the sensation lasts longer than 10 minutes, becomes severe, or is accompanied by redness or visual changes, rinse the eye with sterile saline and seek ophthalmic evaluation promptly.
Acular is generally approved for patients aged 12 years and older. Use in younger children should only occur under the direct supervision and prescription of a pediatric ophthalmologist.
Yes, but keep the bottle in its original packaging, include a copy of the prescription, and declare it at customs if required. Ensure the medication remains within the recommended temperature range during travel.
Artificial tears can be used alongside Acular, but it is best to administer them at least 5 minutes apart to avoid dilution of either product. Consult an eye-care professional for a personalized schedule.
The bottle design protects the solution from light and contamination while allowing patients to dispense exact drops. Once opened, the bottle maintains sterility for a limited period (usually 30 days).
Transient blurred vision may occur briefly after instillation. Patients should avoid driving or operating heavy machinery until vision clears, typically within a few minutes.
