Claritin and Zyrtec are popular over-the-counter antihistamines. Doctors consider them safe and effective treatments for minor allergies. Both are second-generation antihistamines. These cause less drowsiness than first-generation antihistamines.
Allergy Medications
First generation antihistamines, while very effective at controlling symptoms, are often associated with symptoms in older adults such as anxiety, confusion, sedation, blurred vision, reduced mental alertness, urinary retention and constipation.
Second-generation antihistamines are effective in elderly patients with allergic rhinitis in drops and oral forms. Their safety is based on a relatively low rate of passage across the blood–brain barrier.
You should not use Zyrtec-D if you have narrow-angle glaucoma, severe high blood pressure (hypertension), severe coronary artery disease, if you are unable to urinate, or if you are allergic to hydroxyzine (Atarax, Vistaril). Do not use this medicine if you have taken an MAO inhibitor in the past 14 days.
Some elderly people may have higher risk of side effects because of poor kidney function. The drowsiness and fatigue which may occur in a small percentage of patients may be more of a problem for the elderly because of the increased risk of bone fracture if they fall.
Allergists recommend long-acting, non-sedating antihistamines — ones that won't make you sleepy — for everyday use. Though you may know them by their brand names, the generic versions tackle the same problems: Cetirizine (Zyrtec®, Aller-Tec®, Wall-Zyr®). Fexofenadine (Allegra®, Aller-ease®, Aller-Fex®, Wal-Fex®).
Claritin comes highly recommended by Dr. Fineman as an effective antihistamine. This medication comes in a wide variety of formats, including tablets, gel capsule pills, chewables and orally-disintegrating tablets (for those who have trouble swallowing pills).

Non-sedating antihistamines are used in the long-term control of allergy, as in hay fever, eczema, sinusitis, and chronic urticaria. No serious side effects have been reported.
“The most common side effects you tend to see are fatigue, headaches, and dry mouth,” says Shih. If you're someone for whom the benefits of regular antihistamine use far outweighs the occasional minor side effect, longterm use is safe for most adults and children, he adds.

Pharmacological action occurs after 30-60 minutes and persists for about 4-6 hours.
Drowsiness, tiredness, and dry mouth may occur. Stomach pain may also occur, especially in children. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
