When determining the correct Pataday dosage, it is essential to identify your specific allergy triggers. If you are currently dealing with red, swollen, and itchy eyes due to pollen, pet dander, or grass, Pataday (Olopatadine) remains the clinical gold standard for relief. Furthermore, while it was formerly available only by prescription, it has now become the #1 pharmacist-recommended OTC eye drop in the USA for allergic conjunctivitis.
However, patients must be aware that there are three distinct formulations of Pataday available on the shelf. Consequently, understanding the difference between these concentrations is crucial to getting the right relief for your specific symptoms.
The 3 Types of Pataday: Which One is Right for You?
- Pataday Once Daily Relief (0.2%): Provides up to 24 hours of relief with a single drop. It is the balanced option for daily convenience.
- Pataday Once Daily Extra Strength (0.7%): It is designed for those with acute allergies who need maximum concentration to last all day.
- Pataday Twice Daily Relief (0.1%): Designed to be applied every 6 to 8 hours. It is ideal for those who prefer repeated applications throughout the day.
Pataday Dosage Chart
| Product | Concentration | Dosage (Adults & Kids 2+) | Relief Duration |
| Once Daily | Olopatadine 0.2% | 1 drop per eye, once daily | Up to 24 hours |
| Extra Strength | Olopatadine 0.7% | 1 drop per eye, once daily | 24 Hours (Max Strength) |
| Twice Daily | Olopatadine 0.1% | 1 drop per eye, twice daily | 6-8 hours per dose |
Pharmacist Note: If you wear contact lenses, remove them before applying Pataday and wait at least 10 minutes before reinserting. This prevents the preservatives in the drops from being absorbed by the lens.
The original long-lasting OTC formula. With 0.2% Olopatadine, it provides up to 16 hours of relief. This is the go-to clinical choice for pet dander and grass allergies, offering a full day of comfort with a single morning application.

The ultimate value for severe allergy sufferers. This twin pack contains the maximum 0.7% Olopatadine concentration. As a pharmacist, I recommend this for 24-hour relief from intense itching caused by ragweed and pollen. One drop, once a day, for both eyes.

Perfect for those who prefer an eye-wash effect throughout the day. This 0.1% formulation is applied twice daily (every 6-8 hours). It is a great clinical option for maintaining consistent antihistamine levels in the eyes during peak allergy hours.

Pharmacist Tip: Pataday vs. Decongestant Eye Drops
Many patients make the mistake of using decongestant eye drops (those marketed to “get the red out” instantly) for long periods. These products can cause a “rebound effect”—once you stop, your eyes become even redder.
Pataday treats the cause (histamine), not just the symptom. If you feel you can’t live without your redness-relief drops, you might be in a rebound cycle. Read my full article: Are You Addicted to Decongestant Eye Drops? How to Stop the Rebound Cycle.
Conjunctivitis: Allergic vs. Bacterial?
It is vital to distinguish between the two before starting treatment:
- Allergic: Intense itching, watery discharge, usually affects both eyes. Responds to Pataday.
- Bacterial: Eyes feel “stuck shut” in the morning, thick yellow/green discharge. This requires prescription antibiotic drops and a doctor’s visit.
If your eye allergies are accompanied by sneezing and a runny nose, you need systemic support. In these cases, I recommend pairing your eye drops with an oral antihistamine like Xyzal. Follow my: Xyzal Dosage Guide for correct administration.
Original prescription strength Levocetirizine. Xyzal provides fast-acting, 24-hour relief from sneezing, runny nose, and itchy throat. As a pharmacist, I recommend taking this 5mg dose in the evening for maximum effectiveness against morning allergy peaks.

Prevention & Hydration
For chronic allergy sufferers, prevention is everything. Supplementing your diet with Black Currant Oil (rich in GLA) and a Quercetin & Bromelain complex helps stabilize mast cells, reducing the allergic reaction before it starts.
The primary natural alternative for seasonal support. Rich in Gamma-Linolenic Acid (GLA), black currant oil helps modulate the body’s inflammatory response. It is an excellent clinical addition for those looking to support ocular moisture and reduce systemic allergy sensitivity naturally.

A potent natural supplement for histamine support. Quercetin acts as a natural antioxidant to help stabilize mast cells, while Bromelain enhances its absorption and provides sinus comfort. This combination is a staple in my pharmacist-verified natural allergy relief protocol.

Furthermore, allergic eyes are often dry and irritated. Using lubricant drops like Systane helps physically “wash away” allergens while keeping the ocular surface hydrated and protected.
The ideal companion for allergy sufferers. This preservative-free formula provides long-lasting hydration without irritating sensitive eyes. As a pharmacist, I recommend these single-use vials to flush out allergens and soothe dryness throughout the day, especially when using antihistamine drops like Pataday.
