[Hay fever therapy with 2 non-sedating antihistaminics]

In a double blind study patients with hay fever were treated with Astemizole or Terfenadine for 3 to 4 weeks, 12 patients with Astemizole and 6 patients with Terfenadine. Doctors and patients judged Astemizole to be more effective than terfenadine. Statistical evaluation was not possible because of the small group. There was no sedation induced by either of the drugs.
