All allergy medicines are not the same. Many people who have allergies have both the indoor and outdoor kind. But not all allergy medicines are approved to treat the symptoms of both. Approval for a particular allergy does not necessarily indicate how well a product will work for you. So, ask your doctor if ZYRTEC is right for you.
