About Zyrtec Syrup
Zyrtec Syrup 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.
Zyrtec Syrup 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, Zyrtec Syrup 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 Zyrtec Syrup exactly as your doctor has prescribed you. Like all medicines, Zyrtec Syrup 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 Zyrtec Syrup 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 Zyrtec Syrup; your doctor will decide whether breastfeeding mothers can take Zyrtec Syrup or not.
