Frequently Asked Questions

How does bilastine compare to cetirizine (Zyrtec) and loratadine (Claratyne)?

Bilastine is a newer (third-generation) antihistamine with greater H1 receptor selectivity and higher lipophilicity-matched blood-brain barrier impermeability than either cetirizine or loratadine. Clinical studies show bilastine has equivalent or superior efficacy to cetirizine and loratadine for hay fever symptom relief with a superior drowsiness profile — in placebo-controlled trials, bilastine showed no difference from placebo on sedation measures, whereas cetirizine showed mild sedation in some studies. It is also not metabolised by the liver, reducing drug interaction risk.

What is the important food interaction with bilastine?

Bilastine must be taken on an empty stomach — food (particularly fruit juices including orange, apple, and grapefruit juice) significantly reduces bilastine absorption by inhibiting the intestinal transporter OATP. Take Histaclear at least 1 hour before meals or 2 hours after eating, with water only. This is critical for full effectiveness — taking with food can reduce absorption by up to 30%.

Is Histaclear/bilastine safe to drive after taking?

Yes — bilastine is classified as non-sedating and is safe for driving at the recommended 10mg dose. Multiple studies confirm bilastine has no greater impairment on driving performance or psychomotor function than placebo. This distinguishes it from first-generation antihistamines (chlorphenamine, promethazine) and even some second-generation antihistamines at higher doses.

Can Histaclear be taken once daily?

Yes — bilastine 10mg is dosed once daily for adults and children over 12 years. The 24-hour duration of action makes once-daily dosing appropriate for continuous allergy control. Take consistently at the same time each day, on an empty stomach, for best results.

Is Histaclear available without prescription in NZ?

Yes — Histaclear bilastine 10mg 90 tablets is available as a Pharmacy Medicine (P medicine) from registered pharmacies without a prescription. Quantity restrictions may apply per purchase.
