Which Allertec is better?

Allertec Fexo contains the active substance fexofenadine. Fexofenadine is a second-generation antihistamine, which means that it causes fewer side effects such as drowsiness. To a small extent, it penetrates into the central nervous system. With long-term use, its half-life is about 11-15 h (it has a long pharmacological activity). It is used, m.in, to treat the symptoms of hay fever: https://www.gdziepolek.pl/produkty/106968/allertec-fexo-tabletki-powlekane/ulotka/258382 While Allertec WZF contains cetirizine as the active substance. Cetirizine is also a second-generation antihistamine. The effect of the drug appears after about 1 hour after administration of the preparation and lasts about 24 hours. The half-life of cetirizine is 8-10 h (it has a shorter pharmacological activity). It is used, m.in, to treat the symptoms of hay fever: https://www.gdziepolek.pl/produkty/3539/allertec-wzf-tabletki-powlekane/ulotka/96560 Cetirizine causes more side effects than fexofenadine and is characterized by a shorter total duration of action. The tolerance of individual antihistamines is also determined individually. After trying both preparations, you can determine which preparation will be more suitable for you.
