Get Patanase Online

Patanase (olopatadine nasal spray) is a prescription antihistamine approved to treat the nasal symptoms of seasonal and perennial allergic rhinitis in adults and children 6 years and older. It relieves sneezing, nasal congestion, runny nose, and nasal itching.

Patanase works by blocking H1 histamine receptors in the nasal lining. When allergens like pollen or pet dander trigger an allergic response, histamine is released and causes nasal symptoms. By blocking this receptor, Patanase reduces sneezing, itching, and mucus production.

Many patients notice improvement in nasal symptoms within 30 minutes to a few hours of the first dose. For optimal results, it is typically used twice daily as directed by your physician.

The most commonly reported side effects include a bitter taste in the mouth, headache, nasal discomfort or burning, and somnolence (drowsiness). Because Patanase can cause drowsiness, use caution when driving or operating heavy machinery, especially when first starting the medication.

Your physician will review your current medications before prescribing Patanase. In some cases it may be combined with other allergy treatments, such as a nasal corticosteroid or an oral antihistamine, but combining it with other agents that cause sedation should be done carefully under medical supervision.

Patanase has been studied for seasonal and perennial allergic rhinitis and is generally well tolerated with extended use. Your prescribing physician will advise on the appropriate duration of treatment based on your symptom pattern and response to therapy.
