2nd A: Allegra is the only NonSedating antihistamine. The FDA allows pnly Allegra to promote as NONsedating. In fact Allegra is the only antihistamine a pilot can take and fly, all others they have to stay grounded until the medicine wears off.

Allegra has more formulations and when it comes to pediatric use or school age children use, there is no way you could convince me to use Zyrtec, for my child. They have a hard enough time staying awake and focusing in class, I will not allow my kids to be hampered by their allergy medicine.

For most adults, daily (every 24 hour) dosing is recommended for Zyrtec. Zyrtec is probably better as a "preventative" antihistamine, and you must keep a certain amount in your bloodstream for it to be most effective. It is not indicated specifically for excess sweating, but may help in some instances.
Have you tried older (but more sedating) antihistamines such as Benadryl (diphenhydramine)? If Zyrtec works, Benadryl would likely work better.
There are other therapies available for excess sweating. Ask your doctor about beta-blockers such as propranolol (Inderal) or perhaps prescription-strength antiperspirants, or other alternatives.
