Safely Buy Zyrtec Syrup ( Cetirizine ) from Canada Prescriptions Plus.

Indications

Cetirizine is an antihistamine used to relieve allergy symptoms such as watery eyes, runny nose, itchy eyes/nose, sneezing, hives, and itching.

Cetirizine works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. Cetirizine does not prevent hives or prevent/treat a serious allergic reaction (such as anaphylaxis).

If your doctor has prescribed epinephrine to treat allergic reactions, always carry your epinephrine injector with you. Do not use cetirizine in place of your epinephrine.

Use and Dosage

If you are taking the over-the-counter product to self-treat, read all directions on the product package before taking this medication. If you have any questions, consult your pharmacist. If your doctor has prescribed this medication, take it as directed, usually once a day.

If you are using the chewable tablets, chew each tablet well and swallow. If you are using the rapidly-dissolving tablet, allow the tablet to dissolve on the tongue and then swallow, with or without water. If you are using the liquid form of this medication, measure the dose carefully using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

The dosage is based on your age, medical condition, and response to treatment. Do not increase your dose or take this medication more often than directed.

Tell your doctor if your allergy symptoms do not improve, if your hives do not improve after 3 days of treatment, or if your hives last more than 6 weeks. Get medical help right away if your condition worsens or if you think you have a serious medical problem (such as a very serious allergic reaction/anaphylaxis).
