“Zyrtec can cause drowsiness,” Dr. Brooks says. “While not as frequent as for older antihistamines like Benadryl, I still see drowsiness with Zyrtec quite a bit. In fact, pilots are not ...
Doxylamine and other first-generation antihistamines are the most widely used sleep medications in the world. [6] Typical side effects of doxylamine (at recommended doses) include dizziness, drowsiness, grogginess, and dry mouth, among others. [7] [4] As an antihistamine, doxylamine is an inverse agonist of the histamine H 1 receptor.
Cetirizine is a second-generation antihistamine used to treat allergic rhinitis (hay fever), dermatitis, and urticaria (hives). [5] It is taken by mouth. [6] Effects generally begin within thirty minutes and last for about a day. [6] The degree of benefit is similar to other antihistamines such as diphenhydramine, which is a first-generation ...
Diphenhydramine tablets. Diphenhydramine is a first-generation antihistamine used to treat several conditions ... Its effects on central H 1 receptors cause drowsiness.
Antihistamines are drugs which treat allergic rhinitis, common cold, influenza, and other allergies. [1] Typically, people take antihistamines as an inexpensive, generic (not patented) drug that can be bought without a prescription and provides relief from nasal congestion, sneezing, or hives caused by pollen, dust mites, or animal allergy with few side effects.

Fexofenadine does not readily cross the blood–brain barrier, so is less likely to cause drowsiness in comparison to other antihistamines that readily cross that barrier (i.e., first-generation antihistamines such as diphenhydramine). In general, fexofenadine takes about an hour to take effect, though this may be affected by the choice of ...
Pheniramine (trade name Avil among others) is an antihistamine with anticholinergic properties used to treat allergic conditions such as hay fever or urticaria.It has relatively strong sedative effects, and may sometimes be used off-label as an over-the-counter sleeping pill in a similar manner to other sedating antihistamines such as diphenhydramine.
Ebastine is a H 1 antihistamine with low potential for causing drowsiness. It does not penetrate the blood–brain barrier to a significant amount and thus combines an effective block of the H 1 receptor in peripheral tissue with a low incidence of central side effects, i.e. seldom causing sedation or drowsiness.
