New-school antihistamines encompass drugs like:

Cetirizine (Zyrtec)Fexofenadine (Allegra)Loratadine (Claritin)

These drugs, unequal the old-school ones, room designed so that they can’tcross the obstacle that protects the brain from harmful chemicals in her blood.The result is they deserve to only block histamine receptors uncovered in the rest of yourbody, and not in the brain, and also so they develop allergy relief with lot lessdrowsiness and other next effects.

That said, this doesn’t median they can’tmake you drowsy, and taking castle with other antihistamines, alcohol, or drugsthat influence the central nervous mechanism (bupropion, benzodiazepines likealprazolam or clonazepam, and others) deserve to produce an extensive additive effectsthat can impair your capability to do decisions or operate a vehicle.
