CETIRIZINE
About
CETIRIZINE belongs to a class of drugs called anti-histamine or anti-allergic. It contains cetirizine, primarily used to treat various kinds of allergies. An allergy is an immune system response to foreign elements typically not harmful to your body. These foreign elements are known as ‘allergens.’ Allergic condition varies from person to person. Some might be allergic to certain foods and seasonal allergies like hay fever. At the same time, others might be allergic to pollen or pet dander.
CETIRIZINE contains cetirizine (anti-histamine), which is used to treat allergies as it blocks the effects of a chemical messenger known as ‘histamine,’ which is naturally involved in allergic reactions. Additionally, CETIRIZINE also treats hay fever (seasonal allergic rhinitis), round-the-year dust or pet allergies (perennial allergic rhinitis), and urticaria (swelling, redness, and itchiness of the skin). In short, it helps to relieve the discomfort and unpleasant symptoms that occur due to allergic conditions, like blocked/runny/itchy nose, red/watery eyes, and skin rashes.
Always take CETIRIZINE exactly as your doctor has prescribed you. Like all medicines, CETIRIZINE can cause some side effects; however, not everybody gets them. If you observe tiredness symptoms, feeling sleepy, abdominal pain, headache, dizziness, dry mouth, sore throat, nausea, cold-like nose symptoms (in children), or diarrhoea (in children). In very rare cases, people might have thought about committing suicide. If you feel like this, stop the medicine and immediately contact your doctor.
You should not take the CETIRIZINE if you are allergic to cetirizine or have severe kidney failure (creatinine clearance less than 10 ml/min), urinary retention problem, and fructose intolerance. Do not give this medicine to children younger than six years of age. Check with your doctor if you are taking midodrine to treat low blood pressure and ritonavir for HIV infection. Let your doctor know if you are a pregnant woman or a nursing mother before taking CETIRIZINE; your doctor will decide whether breastfeeding mothers can take CETIRIZINE or not.

Hay fever is an allergy caused due to outdoor or indoor allergens, such as pollen, dust mites, or tiny flecks of skin and saliva shed by cats, dogs, and other animals with fur or feathers (pet dander). It leads to cold-like symptoms (running nose, watery eyes).
Depending upon the severity of allergic conditions due to allergens, CETIRIZINE can be safely taken daily until you get complete relief as long as your doctor has advised you to take it.
CETIRIZINE is an antihistamine providing instant relief from allergic conditions; however, in some people it may cause sleepiness and induce some drowsiness during the day. Hence, you are recommended to take it in the nighttime in case you are experiencing excessive drowsiness in the day.
