Patients with moderate renal impairment had a 3-fold increase in half-life and 70 % decrease in clearance compared to healthy volunteers.

If your baby is not feeding as well as usual, seems unusually sleepy, or if you have any other concerns about your baby, talk to your doctor, pharmacist, health visitor or midwife. In addition to the adverse reactions reported during clinical studies and listed above, the following undesirable effects have been reported in post-marketing experience. Cetirizine, a human metabolite of hydroxyzine, is a potent and selective antagonist of peripheral H 1-receptors. In patients with hepatic impairment and renal impairment, adjustment of the dose is recommended (see renal impairment above).In most respects, Cetirizine and Loratadine are similar, however, some people may find they respond better to one over another. Paediatric population: The half-life of cetirizine was about 6 hours in children of 6-12 years and 5 hours in children 2-6 years. Due to the pharmacokinetic, pharmacodynamic and tolerance profile of cetirizine, no interactions are expected with this antihistamine.

It works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction and gets to work quickly within an hour so it is great as a reactive measure for when you start to present signs of hay fever.

In a 35-day study in children aged 5 to 12, no tolerance to the antihistaminic effect (suppression of wheal and flare) of cetirizine was found.

For example, if you have a reaction to an insect bite, you may only need to take cetirizine for a day or two.Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential, toxicity to reproduction and development 6. Cetirizine is an antihistamine medicine, most commonly found in hay fever and allergy tablets to help relieve symptoms of sneezing, coughing, runny or blocked noses as well as watery and itchy eyes.
