Fexofenadine and alcohol

Can you drink while taking Fexofenadine for hay fever?


Fexofenadine is a potent antihistamine, designed to help you control allergy symptoms. Alcohol is known to intensify the side effects created by antihistamines, so it is best to avoid drinking alcohol when taking Fexofenadine. The common side effects of nausea, diarrhoea, headaches and muscle pain, can become a lot worse if you consume alcohol.
