How long does bilastine take to work?

Could you please clarify for me how long it typically takes for bilastine to start working effectively? I'm interested in understanding the timeframe in which patients can expect to experience its intended effects. Is there a general range of time that's commonly observed, or does it vary significantly from person to person? Additionally, are there any factors that might influence the onset of its effectiveness, such as dosage, food intake, or individual physiology? Thank you for your insights.
