What are Cetirizine tablets?

Cetirizine is a non-drowsy antihistamine medicine. It is also avalable as a Cetirizine Oral Solution.

It is available on prescription, but you do not need a prescription to purchase these tablets; they are available to purchase over the counter.

You can buy Cetirizine 10mg tablets from Medicine Direct following an online consultation with one of our registered doctors, who will prescribe this medication if they deem it the most suitable treatment for your symptoms. From there, you can order it from our registered online pharmacy; order by 2pm and you will receive free next day delivery.

Cetirizine 10mg tablets come in packets of 7, 10 or 30 tablets.

Why it's used?

Cetirizine 10mg tablets contain the active ingredient cetirizine hydrochloride, which is an effective antihistamine used to relieve the symptoms associated with allergies.

In particular, it is used as a relief for the following common allergies:

  • Hay fever
  • Certain food allergies
  • Conjunctivitis
  • Eczema
  • Hives
  • Reactions to insect bites or stings

Because it is a non-drowsy antihistamine, you are far less likely to suffer from drowsiness while taking Cetirizine tablets compared to other antihistamine medication.

It is suitable for adults and children aged 6 and above.

How does Cetirizine treat hay fever?

Cetirizine belongs to a group of medicines known as antihistamines.

It contains the active ingredient cetirizine hydrochloride, which works by blocking the effects of a chemical called histamine.

Histamine is produced by your body when you come into contact with an allergy trigger, such as pollen, animal fur or dust. Histamine is useful for the body in most cases, but in an allergic reaction it causes unpleasant symptoms.

Cetirizine works to block this chemical's effects, thus lessening the symptoms and allowing you to get on with your life.

Do I need a prescription to order Cetirizine Tablets?

This medication is available to buy without a prescription and can be bought in pharmacies and supermarkets.

However, a doctor may prescribe Cetirizine 10mg tablets if you make an appointment to see them about your allergies.

At Medicine Direct, one of our registered health professionals will prescribe this medicine if they deem it the most appropriate treatment for your allergies.

When should Cetirizine Tablets not be used?

Cetirizine 10mg tablets provide effective relief for the symptoms of allergies and hay fever, but they are not suitable for everyone to use.

You should not use this medication if:

  • You are allergic to cetirizine hydrochloride or any of the other ingredients contained in this medicine (please refer to the Ingredients tab for full details)
  • You have a severe kidney disease
  • You are known to be allergic to hydroxyzine
  • You are known to be allergic to any drugs from the piperazine family of medicines, such as buclizine, meclozine, cyclizine or levocetirizine

This medicine is not suitable for children under the age of 6.

Always read the patient information leaflet for full details on who may not be suitable to use Cetirizine tablets.

Further precautions can be found under the Warnings and Drug Interactions tab on this page.

Can I use Cetirizine tablets if I am pregnant or breastfeeding?

Speak to your doctor before you use Cetirizine if you are currently pregnant, think you might be pregnant or are trying to get pregnant.

There may be a safer alternative medication for you to use to control allergy symptoms or hay fever.

Similarly, please speak to your doctor or pharmacist before taking this medicine if you are currently breastfeeding. This is especially important if your baby has any health problems, was born premature or with a low birth weight.

Only small amounts of the medicine will get into your breast milk, but you should still check to make sure it is safe to use.

Certirizine Dosage

For adults and children over 12 years old, the average dose for Cetirizine is 10mg, which should be taken as one tablet once a day. This is to relieve symptoms of allergies and the symptoms of hay fever.

If you suffer from kidney problems the dose is likely to be lower than this.

If a doctor has prescribed Cetirizine tablets for your child, they will base the dosage on their age or weight. The usual recommended dose for children aged 6 to 12 years old is 5mg, to be taken as half a tablet twice a day.

How should Cetirizine Tablets be used?

Always take Cetirizine tablets exactly as instructed by your doctor or pharmacist. Read the patient information leaflet thoroughly before you start taking the tablets; speak to your doctor or pharmacist for further advice if you are still unsure how to take them.

Cetirizine tablets can be taken with or without food.

Swallow the tablets whole with a drink of water, juice or milk. Do not crush or chew the tablets.

When should Cetirizine tablets be used?

In some circumstances, you might only need to take Cetirizine on days you are suffering from allergy symptoms, such as being exposed to an allergy trigger like dust or animal fur.

On the other hand, you may need to take the tablets on a regular basis to prevent the symptoms of allergies. For instance, you may need to take it regularly during the spring and summer months to stop hay fever symptoms.

What if I take more than I am supposed to?

This medicine is considered to be generally safe, so taking an extra dose is not likely to do you any harm.

Taking an extra dose may result in you or your child suffering from some of the common undesired effects associated with this medicine. If this happens, speak to your doctor or pharmacist for guidance.

What if I forget to take it?

If you forget to take a dose, just take it as soon as you remember. If it is almost time for your next dose, just skip the dose you missed and continue taking Cetirizine as normal.

Never take an extra dose of medicine to try and make up for missing a previous one.

If your child is taking this medicine and you forget to give them a dose, you can give them the missed dose if it is within 4 hours of when they should have originally taken it.

If you only remember more than 4 hours later, skip the dose they missed and wait until the next scheduled dose. Then, carry on as usual.

To ensure you do not forget to take your medication, try to take the tablets at the same time every day. Some people find it useful to set an alarm as a reminder.

How long does it take to work?

After taking Cetirizine, adults and children should start to feel better within one hour.

How long does it last?

The medicine should take effect for 24 hours. If required, you should take another tablet after 24 hours if your symptoms start to come back.

What if I take twice the dosage?

You should never take a higher dosage of a medicine than your doctor or pharmacist has instructed you to. Taking twice the dosage will not make the medicine any more effective and may increase your risk of side effects.
