Cetirizine can be used in combination with pseudoephedrine, such as Sudafed or others.
Cetirizine, an antihistamine, works by blocking the activity of histamine. Histamine is a naturally occurring substance in the body that can cause allergic reactions. Cetirizine is also known as an antihistamine that does not cause sleepiness, unlike other medications.
Cetirizine is effective for approximately 24 hours in most people and has a half-life of about 10 hours. The kidneys slowly eliminate it and excrete it in the urine.
10mg tablets:
Children between 6 - 12 years old take half a tablet twice a day
