Cetirizine

Cetirizine is a popular antihistamine that’s used to treat allergies such as hay fever and animal dander allergies. It can also help to control other allergic conditions such as conjunctivitis, eczema, hives, and others. It works by blocking the effect that histamine has on your body, relieving the symptoms associated with many allergic reactions.


Cetirizine is effective for many people, and is popular between the months of March – September to help relieve symptoms such as:


  • Runny nose
  • Watery eyes
  • Itchy eyes
  • Sneezing
  • Coughing

It’s widely available online, in pharmacies, and even in some supermarkets, but you should still take caution when using the treatment as it’s still a drug that affects how your body works. If you have any concerns, speak to your local pharmacist and ask their advice.



Prices start from £0.72 for 30 tablets

What is Cetirizine?

Cetirizine is an antihistamine medicine that treats different types of allergies including:

  • Hay fever
  • Conjunctivitis
  • Eczema
  • Hives
  • Insect bites and stings
  • Some food allergies

Cetirizine is an effective treatment for both seasonal allergies, and allergies that occur year-round.

Cetirizine is a non-drowsy antihistamine, so it shouldn’t affect your ability to drive. However, fatigue is listed as a side effect, so always make sure you know how the medication affects you before driving.

How does Cetirizine work?

Cetirizine is an antihistamine. Histamine is produced by your body as a response to an allergen or perceived threat, causing many symptoms that are associated with allergies, such as a runny nose, puffy eyes, itching and sneezing, to name a few. Whilst this is your body trying to protect you, it can cause some unpleasant symptoms and be quite uncomfortable to live with.

Cetirizine helps to relieve these symptoms by blocking the effect that histamine has on the body, meaning that you should experience fewer or less-severe reactions to allergens.

Can I take cetirizine?

Luckily, this is a medication that’s generally well-tolerated, and only those with certain allergies or severe disorders should avoid or take extreme care. Examples of conditions that might mean the medicine is unsafe to use are:

  • Severe kidney disease
  • Allergy to cetirizine
  • Allergy to hydroxyzine
  • Allergy to drugs in the piperazine family
  • Epilepsy
  • At risk of urinary retention

If any of the above complaints or conditions apply to you, you should speak to your GP or pharmacist and ask their advice before starting treatment with cetirizine. There may be other medications available to you that are more suitable, or you might just be advised to take extreme caution with it. Never take a medication if you have any concerns that it might affect your health.

Whilst no severe interactions with other medications are reported, you should also inform your pharmacist if you’re taking any other drugs at all, whether these are on prescription, bought over the counter, or are herbal remedies. Always read the patient information leaflet that comes with your medicine to make sure you know what you can and can’t take with it.

What are the side effects of cetirizine?

Although most side effects are mild, some people do experience symptoms associated with taking cetirizine. However, most people that experience them find that they would rather live with the side effects than the condition that cetirizine treats. We’re going to list some of the most common side effects associated with the medicine, though you should always read the patient information leaflet to familiarise yourself with all of the possibile symptoms. Most commonly reported are:

  • Fatigue
  • Dizziness
  • Headache
  • Dry mouth
  • Nausea
  • Pharyngitis
  • Rhinitis
  • Pruritis
  • Abdominal pain
  • Agitation
  • Feeling weak
  • Feeling generally unwell

Whilst fatigue is listed as a side effect, cetirizine is generally a non-drowsy medication, unlike some other antihistamines used to relieve symptoms of allergies.

How do you take cetirizine?

Cetirizine most commonly comes as 10mg tablets and can be bought online, from your GP, and from supermarkets and pharmacies in this form.

Cetirizine is most often a once-a-day tablet and can be taken with or without food. Depending on your allergy, there are two ways of taking the medication:

  • Daily: if your allergy is seasonal (for example, hay fever), you might want to take cetirizine daily during times that pollen counts are high. This will help to protect you throughout the time that you’re at risk.
  • On-demand: if your allergy isn’t specific to a season (for example, animal dander), you can choose to take cetirizine only when you know you’ll be around an allergen.

Tablets should be swallowed whole with a glass of water and can be taken with or without food.

Can I drive while taking cetirizine?

Cetirizine is generally a non-drowsy antihistamine, meaning that you should be safe to drive whilst taking it. However, as fatigue is listed as a side effect in the patient information leaflet, you should always wait to see how it affects you before driving. If you feel tired, dizzy, confused or generally unwell, you should avoid driving until you feel better.

Can I still use my epi-pen if I use cetirizine?

Yes. If you have hay fever but also find that you need to use your epi-pen for another allergy, you should do so without hesitation. There are no known serious interactions with other medicines, and cetirizine must not be used as a substitute for epinephrine/adrenaline. Cetirizine will not save you from anaphylactic shock. Always use your epi-pen if you start to feel as though you’re experiencing anaphylaxis.

What if cetirizine doesn’t help me?

There are other options available for those struggling with allergies if cetirizine tablets don’t help with your symptoms. Examples include:

  • Loratadine (another type of antihistamine)
  • Nasal corticosteroid sprays
  • Decongestant medications

Depending on your allergy, you may also be able to avoid triggers wherever possible to avoid experiencing troublesome symptoms. However, this isn’t always possible in cases such as hay-fever.

If you find that cetirizine doesn’t improve your symptoms, please visit your local pharmacy to discuss other options that might be available to you.

If you don’t know the cause of your allergy, you should make an appointment with your GP and ask to be referred to an allergy clinic to find the cause of your symptoms. This should help you avoid any triggers.
