"Both the oral solution and tablets offer patients powerful and long-lasting allergy relief."

"Building upon our long history in the allergy treatment arena, this opportunity allows us to continue our leadership position in this field and demonstrates our commitment to providing new treatments for the millions of allergy sufferers in the U.S."
