The pharmacokinetics of cetirizine have been found to increase linearly with dose across a range of 5 to 60 mg. [9] Its C max following a single dose has been found to be 257 ng/mL for 10 mg and 580 ng/mL for 20 mg. [8] Food has no effect on the bioavailability of cetirizine but has been found to delay the T max by 1.7 hours (i.e., to ...
Progesterone has noticeable effects on respiratory physiology, increasing minute volume (the amount of air breathed in and out of the lungs in 1 minute) by 40% in the first trimester via an increase in tidal volume alone, as the respiratory rate does not change during pregnancy.

Use in pregnancy appears safe but has not been well studied and use when breastfeeding is of unclear safety. [5] It is classified as a second-generation antihistamine and works by blocking histamine H 1-receptors. [6] [3] Levocetirizine was approved for medical use in the United States in 2007, [3] and is available as a generic medication. [4]
