Bilastine acts as a selective histamine H1 receptor antagonist for seasonal allergic rhinitis. Inhibition of receptor binding site activity prevents common manifestations like sneezing or itching.
Bilastine belongs to the second-generation antihistamine class, which is designed to reduce the effects of histamine-a chemical released during allergic reactions. By targeting histamine pathways, this compound helps manage symptoms such as itching, sneezing, and watery eyes. It is the active substance present in products marketed under the name Ilaxten.
In Singapore, bilastine is supplied mainly as oral tablets, commonly listed under the brand Ilaxten. Both the branded version and its generic equivalents are available in the same dosage strength, allowing patients to choose based on availability. Tablet form ensures convenient, once-daily dosing for most users.
Because bilastine does not readily cross the blood-brain barrier, it is less likely to cause drowsiness, making it a practical option for adults and older children who need to stay alert during daily activities.
When an allergen contacts the body, mast cells release histamine, which binds to receptors in the nose, skin, and eyes, producing typical allergy symptoms. Bilastine blocks these receptors, preventing histamine from attaching and thereby reducing the visible signs of an allergic response. The effect begins within an hour and can last for up to 24 hours with a single dose.
These experiences are usually brief and resolve without medical intervention.
If any of these occur, immediate medical attention is advised.
For a complete interaction list, refer to the specific medication’s information sheet.
Store tablets in a cool, dry place away from direct sunlight. The product remains stable at room temperature typical of Singapore’s climate. Treatment duration varies: some users take the drug seasonally, while others may need continuous use for chronic hives. Because strengths and packaging can differ between Ilaxten and its generic versions, always follow the instructions that accompany the exact product you have.
