March/April OTC Product Roundup: Allergies

As allergy season kicks into high gear, pharmacists become the go-to heroes for itchy eyes and runny noses. With aisles full of OTC antihistamines, decongestants, and nasal sprays, helping patients pick the right product can be like a puzzle. This guide breaks down the best OTC allergy relief options so your patients can spend less time sneezing and more time enjoying the warmer weather.

FOR ITCHY EYES: Pataday Once Daily Relief Extra Strength Eye Drops

Olopatadine hydrochloride ophthalmic solution 0.7%

Manufactured by Alcon

Pataday Once Daily Relief Extra

Strength Eye Drops contain olopatadine, an antihistamine, which blocks histamine effects. The extra-strength formula offers long-lasting relief from symptoms such as itching, redness, and watery eyes with just 1 drop per eye, once a day for convenience.

Clinical Pearls

• For best results, use the drops at the same time each day. This ensures consistent 24-hour symptom relief and prevents flare-ups.
• Pataday can be used alongside lubricating eye drops. However, make sure to space them out by at least 5 minutes to avoid washing out the effects.
• Be sure to remove contact lenses before applying Pataday and wait at least 10 minutes before reinserting them to avoid potential irritation.

FOR NASAL CONGESTION: Flonase Sensimist

Fluticasone furoate 27.5 μg

Manufactured by Haleon

Flonase Sensimist works by delivering fluticasone furoate, a corticosteroid that reduces inflammation in the nasal passages. It targets allergic reactions by blocking histamine and other substances that cause symptoms such as congestion and runny nose. Regular use provides 24-hour relief for seasonal and year-round allergies.

Clinical Pearls

• Flonase Sensimist is FDA approved for use in children 2 years and older, making it a safe option for family-wide allergy treatment.
• Be sure to prime the spray before the first use by pumping it a few times until a fine mist appears. This ensures a proper dosage.
• Long-term use of nasal steroids can occasionally lead to nosebleeds, nasal irritation, or sore throat.

FOR SNEEZING: Zyrtec Liquid Gels

Cetirizine HCI 10 mg

Manufactured by Kenvue

Zyrtec Liquid Gels contain cetirizine, an antihistamine that works by blocking histamine receptors, preventing allergy symptoms such as sneezing, runny nose, and itching. The liquid gel form allows for fast absorption, providing relief within 1 hour. It offers 24-hour symptom control for seasonal and indoor allergies without causing significant drowsiness.

Clinical Pearls

• Alcohol can increase the sedative effects of cetirizine, so it is advisable to avoid drinking while using Zyrtec to prevent excessive drowsiness.
• Because cetirizine is primarily excreted through the kidneys, dosage adjustments may be necessary for patients with kidney issues.
• Zyrtec Liquid Gels are approved for children aged 6 and older, but liquid or chewable forms are recommended for younger children, who may have trouble swallowing gels.
