Buy Levocetirizine

Levocetirizine is a treatment for hay fever and allergy symptoms, belonging to a group of medicines called antihistamines. This medication can be used to relieve the symptoms of allergic rhinitis caused by pollen, house dust mites, mould or animals. Levocetirizine can also be used to treat nettle rash (urticaria), also known as hives.

How does levocetirizine relieve allergy symptoms?

Levocetirizine dihydrochloride is a type of medicine called an antihistamine. Levocetirizine, and other antihistamines, work by blocking the release of histamine, a chemical that is released during an allergic reaction. Blocking this chemical helps to relieve symptoms such as a runny nose, itchy eyes and sneezing.



The recommended dosage for levocetirizine for adults and children over the age of 6 years old is one 5mg tablet per day. The dose for children over 6 may be lower depending on their body weight. The duration of treatment will be determined by your doctor or Chemist4U pharmacist. Levocetirizine can be taken with or without food, but caution should be taken when taking this medication with alcohol.


Side Effects

Like all medicines, there is a possibility that levocetirizine may cause side effects in some people. If you experience any allergic reaction symptoms (swollen face, tongue or throat, trouble swallowing, hives or shortness of breath) seek medical help immediately. Other side effects include: 

  • Dry mouth
  • Headache
  • Tiredness or drowsiness
  • Exhaustion
  • Abdominal pain

As with all medicines, mefenamic acid can cause side effects, but not everyone gets them. If you experience any symptoms of the following rare but severe side effects, stop taking mefenamic acid and seek medical attention immediately: 



Levocetirizine may not be suitable for some people with other health conditions. You shouldn’t use this medicine if: 

  • You are allergic to levocetirizine dihydrochloride, cetirizine, hydroxyzine or any of the other ingredients in this medicine
  • You have a severe impairment of kidney function (severe renal failure with creatinine clearance below 10ml/min)

Talk to your doctor or Chemist4U pharmacist before taking levocetirizine if: 

  • You suffer from a condition that means you’re unable to empty your bladder, such as a spinal cord injury or an enlarged prostate
  • You suffer from epilepsy or you’re at risk of convulsions (seizures)
  • You are scheduled for allergy testing
  • You have been told by your doctor that you have an intolerance to some sugars, as levocetirizine contains lactose
  • You are taking any other medicines or herbal remedies, including those obtained without a prescription 

Pregnancy and Breastfeeding Warning

If you are pregnant, think you may be pregnant, are trying to become pregnant, or if you are breastfeeding, speak to your doctor or Chemist4U pharmacist for expert advice before taking levocetirizine.

Age Restrictions

Levocetirizine is not recommended for children under the age of 6 years old. If your child is suffering from hayfever or other allergy symptoms, speak to a Chemist4U pharmacist for suitable alternatives or browse our wide range of allergy treatments.
