Top Generic choice
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Acular eye drops are a prescription allergic conjunctivitis treatment medication used for relief of itchy, watery, and reddened eyes caused seasonal allergies. In rarer instances it may also be prescribed to relieve swelling in the eye following cataract removal surgery. The active ingredient in the eye drops – Ketorolac – is an NSAID (non-steroidal anti-inflammatory drug) that blocks the production of histamines in the body that promote allergic conjunctivitis. You can buy Acular eye drops from Canpharm.
Allergic conjunctivitis is acute, intermittent, or chronic inflammation of the eyes caused by exposure to an allergen and resulting in redness and watering of the eye along with intense itching. Allergic conjunctivitis can also have nasal symptoms and for most people a standard OTC antihistamine provides sufficient relief from allergic conjunctivitis but for some people a stronger Rx one like Acular generic may be required.

What is Acular (Ketorolac) used for?
Acular (ketorolac tromethamine) eye drops are a nonsteroidal anti-inflammatory drug (NSAID) used to relieve eye pain, burning, stinging, and swelling. It is commonly prescribed for reducing inflammation after eye surgeries, such as cataract removal, and to manage seasonal allergic conjunctivitis symptoms.
How should I use Acular eye drops?
Use Acular as prescribed by your healthcare provider. Typically, it’s applied 1 drop in the affected eye(s) up to 4 times daily, often for a limited duration (usually not exceeding 2 weeks). Tilt your head back, pull down the lower eyelid, and apply the drop carefully without touching the bottle tip to avoid contamination. Close your eye gently after each drop and apply slight pressure to the inner corner of the eye.
What are the common side effects of Acular?
Common side effects may include temporary stinging, burning, or discomfort upon application. Less commonly, users may experience eye redness, blurred vision, dry eyes, or headache. If these effects persist or worsen, contact your healthcare provider.
Are there serious side effects associated with Acular?
Though rare, serious side effects may include corneal thinning or damage, eye infection, and vision changes. Seek medical attention if you experience severe eye pain, sensitivity to light, signs of eye infection, or significant vision changes.
Who should avoid using Acular eye drops?
Avoid Acular if you are allergic to ketorolac, other NSAIDs (like aspirin or ibuprofen), or any of the ingredients in the drops. It should also be used cautiously in people with a history of eye conditions affecting the cornea, those who have bleeding disorders, and those who are pregnant or breastfeeding (consult a healthcare provider for guidance).
Can Acular be used with contact lenses?
Avoid wearing contact lenses while using Acular eye drops unless advised otherwise by your doctor. The preservative in the drops can be absorbed by soft lenses, potentially causing irritation. If you must wear lenses, wait at least 15 minutes after applying the drops.
How should I store Acular eye drops?
Store Acular at room temperature, away from light and moisture. Keep the bottle tightly closed when not in use, and do not freeze. Ensure it is out of reach of children and properly dispose of expired or unused drops as directed by a pharmacist.
Can Acular eye drops interact with other medications?
Ketorolac eye drops typically have minimal systemic absorption, so interactions are rare. However, inform your healthcare provider of all medications, especially other eye drops, oral NSAIDs, or anticoagulants, as combining these may increase the risk of side effects.
What should I do if I miss a dose?
If you miss a dose, apply it as soon as you remember. However, if it’s close to your next scheduled dose, skip the missed dose—do not double up. Follow your regular dosing schedule.
Is it safe to use Acular long-term?
Acular is generally intended for short-term use. Extended use can increase the risk of side effects, such as corneal issues. Always follow your healthcare provider's guidance on the duration of use.
