Cetirizine is one of the most effective hay fever medications. It belongs to a class of drugs called antihistamines. The drug stops the secretion of a naturally occurring chemical known as histamine, which helps relieve the symptoms of hay fever.
Exposure to allergens such as pollen, pet dander, house dust, pollutants and insect bites can make your body produce an allergic reaction. The cells in the lining of your nose, throat and eyes release histamines when they come in contact with the aforementioned allergens. This causes inflammation in your nose, throat and eyes, leading to hay fever symptoms such as sneezing, nasal congestion, runny nose, watery or itchy eyes and sore throat.
If the allergens come in contact with your skin, you will develop skin rash called urticaria. The rash usually triggers by an allergy to a substance such as a detergent or soap.
Your GP or pharmacist can recommend Cetirizine for you, or you can buy it without providing a prescription. Generally, tablet and capsule formations are suitable for adults and teenagers, whereas oral liquid syrups or formulations are advised for younger children. This hay fever medication is not suitable for kids below 2 years of age.
As the pharmacological name suggests, Cetirizine allows the body to stop the secretion of histamine by acting on the histamine receptors. Once histamine secretion is stopped, the inflammation subsides. This is how Cetirizine provides relief from hay fever symptoms.
Before using this antihistamine drug, make sure you read the patient information leaflet. The recommended dosage of Cetirizine for adults and children (6 to 12 years) is 10mg and 5mg once a day respectively. Do not take more than prescribed amount of dose, as overdose can make you drowsy.
Prior to using this hay fever medication, it is important that you speak to your GP/pharmacist if you are pregnant or breastfeeding, have any debilitating medical condition, or using any other medications.
