Pataday® Eye Drops for Allergic Conjunctivitis

Pataday is an antihistamine eye drop used to relieve allergic eye itch. It blocks histamine at the eye surface, easing redness and watering. This page helps you compare strengths, understand use, and see access options with US delivery from Canada, including what it may cost without insurance.

What Pataday Is and How It Works

Pataday® contains olopatadine, an antihistamine that targets histamine H1 receptors in the eye. By reducing histamine’s effects on the conjunctiva, the drops can calm itch, tearing, and irritation triggered by seasonal or environmental allergens. The treatment may also reduce redness that accompanies allergic flares.

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

The class helps manage ocular allergy symptoms caused by pollen, pet dander, dust mites, and similar triggers. It is not a decongestant and does not treat infection. Use it only as directed by the label and your prescriber.

Who It’s For

These drops are used for allergic conjunctivitis in adults and children when a clinician recommends an antihistamine eye medicine. People with narrow-angle glaucoma or certain eye infections should avoid use unless a prescriber specifically advises it. Contact lens wearers should remove lenses before dosing and wait the labeled interval before reinsertion.

Pataday for itchy eyes is referenced for individuals whose primary symptom is persistent allergy itch. If dryness without itch is your main concern, a different approach such as prescription tear substitutes may be considered. Explore our Allergic Conjunctivitis page or browse the Ophthalmology category for related options.

Dosage and Usage

Follow the product label and your prescriber’s guidance. Wash hands before each dose. Tilt your head back slightly, pull down the lower eyelid to create a small pocket, and instill the directed number of drops. Avoid touching the dropper tip to any surface, including the eye or eyelid. If using other eye products, separate them by several minutes in the order advised by your clinician.

Pataday use should match the indicated frequency on the label you receive. Some presentations are used once daily, while others may be used twice daily. If symptoms persist or worsen, contact a healthcare professional for advice rather than increasing the amount on your own.

Strengths and Forms

Olopatadine allergy drops are available in multi-dose bottles with a sterile tip. The brand and comparable generics may come as once-daily or twice-daily options. Availability can vary by country and supplier.

• Liquid ophthalmic solution in preservative-containing bottles
• Extra strength option commonly labeled at 0.7%
• Standard antihistamine eye therapy presentation for allergic itch
• Packaging sizes vary; check the label for bottle volume

Generic Pataday eye drops may be available depending on supply and your prescription. Your prescriber can advise whether a generic is appropriate for your plan.

Missed Dose and Timing

If you miss a dose, use it when you remember unless it is close to the next scheduled time. Do not double up to catch up. Keep a consistent routine during allergy season for best results, and avoid allergen exposure when possible.

Storage and Travel Basics

Store the bottle closed, upright, and protected from contamination. Keep it at room temperature as directed on the label and away from moisture. Do not freeze the solution. Keep out of reach of children and pets. When traveling, carry the bottle in your personal item rather than checked luggage and keep the original label available. If you use other eye products, pack them together so you can maintain spacing between items during trips.

Benefits

This medicine can relieve allergen-triggered eye itch and irritation. Many people find once- or twice-daily schedules convenient compared to frequent dosing with lubricants alone. The therapy can be used seasonally or during specific periods when exposure is expected.

Some users notice less tearing and rubbing, which may help avoid additional irritation. If your main problem is dryness without clear allergy triggers, review options discussed in resources like Xiidra Eye Drops.

Side Effects and Safety

Common effects may include brief burning or stinging after instillation, dry eye sensation, headache, or a bitter taste. Mild redness or eyelid discomfort can occur. These reactions usually resolve quickly.

Serious or rare effects can include allergic reactions to components, eye pain, significant redness, changes in vision, or signs of infection. Stop use and seek medical help if severe symptoms occur. If you wear contact lenses, remove them before dosing and wait the labeled period before wearing them again. Preservatives in the bottle can interact with soft lenses if not spaced properly.

Drug Interactions and Cautions

Tell your clinician about all eye treatments and systemic medicines you use. Combining multiple eye products can require spacing to reduce washout. Use caution with contact lenses if the bottle contains preservatives. Do not use the drops to treat infection. Seek guidance if you have glaucoma, recent eye surgery, or significant dry eye disease, as plans may differ.

For background on steroid eye therapies sometimes used in more severe allergic inflammation, see What Is Alrex Used For. If you have other eye conditions that need pressure-lowering agents, your prescriber may choose different medicines than antihistamines; related reading includes Azopt Eye Drops.

What to Expect Over Time

Relief often begins shortly after dosing, with continued benefit during the labeled duration. Regular use during exposure periods can help keep symptoms controlled. Avoid rubbing your eyes, as that can worsen irritation. Track triggers like pollen counts and pet exposure to plan ahead. If response is incomplete, talk with your clinician about whether adjunct options are appropriate.

Some versions use olopatadine once daily. References to Olopatadine 0.2% eye drops appear on certain once-daily labels. Always follow the specific instructions that come with your bottle.

Compare With Alternatives

For mild, occasional symptoms, non-steroidal options may suffice. A mast-cell stabilizer and antihistamine combination class is common in allergy care. If symptoms escalate, a short course of a topical steroid may be considered by a prescriber.

You can discuss non-prescription options like Claritin® Allergy Eye Drops. For steroid-treated flares under clinician guidance, see Lotemax® Ophthalmic Drops. Dry-eye–predominant symptoms may point toward agents that improve tear film rather than antihistamines; see our resource on Xiidra Eye Drops for context.

Patient Suitability and Cost-Saving Tips

Good candidates include adults and children for whom an antihistamine eye drop is appropriate. Those with active eye infections, complex glaucoma histories, or recent surgical procedures should wait for clinician guidance before starting. If you use soft contact lenses, remove them before dosing and follow the labeled wait time before reinserting.
