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 ...
Cannabis use during pregnancy should be avoided. [80] There is no known safe dose of cannabis while pregnant and use of cannabis may lead to birth defects, pre-term birth, or low birth weight. [80] Tetrahydrocannabinol (THC), an active ingredient in cannabis, can both cross the placenta and accumulates in high concentrations in breast milk. [81]
Every drug has specific information listed in its product literature. The British National Formulary used to provide a table of drugs to be avoided or used with caution in pregnancy, and did so using a limited number of key phrases, but now Appendix 4 (which was the Pregnancy table) has been removed. Appendix 4 is now titled "Intravenous ...
A woman's breasts grow during pregnancy, typically 1 to 2 cup sizes. [10] A woman who wore a C cup bra prior to her pregnancy may need to buy an F cup or larger bra while nursing. [11] A woman's torso also grows and her bra band size may increase one or two sizes. [12]
Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
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]
H 1 antagonists, also called H 1 blockers, are a class of medications that block the action of histamine at the H 1 receptor, helping to relieve allergic reactions. Agents where the main therapeutic effect is mediated by negative modulation of histamine receptors are termed antihistamines ; other agents may have antihistaminergic action but are ...
