What is Zyrtec (Cetirizine) used for?

Zyrtec (Cetirizine) is an oral antihistamine used to treat allergy symptoms such as sneezing or a runny nose. It operates by blocking the action of histamines in the body that cause redness, irritation, and swelling caused by allergens. This makes it useful for treating seasonal allergies or watering eyes and sneezing caused by hay fever or pollen. Your doctor may prescribe it for the treatment of other unlisted conditions, as well.

How should I use Zyrtec (Cetirizine)?

Zyrtec (Cetirizine) should be used according to your doctor`s instructions and those included with the packaging to get the most effective results from treatment. The normal regimen is one tablet taken daily, but your particular instructions will depend on your health condition and the severity of your symptoms. These should be swallowed with a large glass of water and may be taken on an empty stomach. A snack or meal is recommended prior to use if you experience nausea. Do not split or crush the tablets to avoid destroying or altering the effects of their contents.

What are the side effects of Zyrtec (Cetirizine)?

Some patients using Zyrtec (Cetirizine) may experience side effects such as:

  • Headaches
  • Drowsiness or dizziness
  • Dry mouth, sore throat, or coughing
  • Mild nausea, upset stomach, or constipation

Stop using the medication and contact your doctor as soon as possible if you experience serious side effects such as confusion, tremors, hyperactivity, vision problems, urinary retention, or irregular heartbeats. These conditions may require lower doses, reduced application frequency, or emergency medical attention in serious cases to prevent further health problems from occurring.

Please Note

Zyrtec (Cetirizine) should not be used to treat patients under two years of age, fructose intolerant, or who have severe kidney failure. Also inform your doctor if you have epilepsy or decreased kidney function as these conditions may cause unexpected health problems during treatment.

Strictly use Zyrtec (Cetirizine) as prescribed and follow all instructions provided by your doctor. Safe, suitable, and optimum dosage can vary and is dependent on the patient`s health and medical history, as well as the condition you are treating.

Zyrtec (Cetirizine) may not be safe or suitable for all patients. Always ensure your doctor is informed if you are pregnant or breastfeeding, using any other type of medication (including non-prescription medicine, vitamins, and supplements), as well as if you have any allergies, other illnesses, or pre-existing medication conditions.

Seek immediate medical attention or proceed to your nearest accident and emergency department if you suffer a hypersensitive or allergic reaction. Symptoms usually present during a reaction of this nature include difficulty breathing or swallowing, swelling of the limbs or face, tight chest, hives, and skin rashes.
