A sedating effect

While these newer antihistamines may still cause drowsiness or a dry mouth, they haven’t been shown to impair a person’s ability to operate a motor vehicle.

Allegra is the only antihistamine that is truly considered to be non-sedating.

Antihistamines for Hay Fever (Allergic Rhinitis)Newer oral antihistamines, such as Xyzal (levocetirizine), Zyrtec (cetirizine), Allegra (fexofenadine), Clarinex (desloratadine) and Clarinex (loratadine), are very effective therapies for the treatment of hay fever.

Older antihistamines, such as diphenhydramine (Benadryl), chlorpheniramine (Chlor-Trimeton), and hydroxyzine (Atarax), also work well but have many side effects.

Antihistamines are also available as nasal sprays for the treatment of allergic rhinitis (nasal allergies) and as eye drops for the treatment of allergic conjunctivitis (eye allergies).

Antihistamines for Hives (Urticaria)Oral antihistamines are the main treatment for hives.

These conditions may include: Antihistamines Available Over-the-Counter (OTC)Probably the most well-known oral antihistamine is Benadryl, which is an older, sedating antihistamine.

While Benadryl is a reasonable medication for the treatment of various allergic conditions, side effects limit its routine use, especially during the daytime.

This may be due to the similar chemical structure of antihistamines and certain psychiatric medications, such as anti-depressants, which are known to increase appetite and lead to weight gain.Placing topical antihistamines on the skin, such as Benadryl cream, can cause contact dermatitis due to the antihistamine.Other Uses for Antihistamines Antihistamines are frequently used for the treatment of other allergic conditions, although they may not be as effective as they are for hay fever and hives.Allegra will also be available OTC in the Spring of 2011.Antihistamines Available by Prescription Only While many older, sedating antihistamines are now available OTC, Atarax is still only available by prescription.
