Cetirizine
How much does Cetirizine cost?
What is Cetirizine?
Cetirizine is used to treat symptoms which are caused by allergies. It is an anti-histamine which can be used to treat hay fever, red eyes, itchy eyes, skin reactions (eczema, urticaria) and reactions to bites/stings. It can be used for other reactions such as food allergies but is most commonly used to treat hay fever.
It is classed as non-drowsy, which means it is less likely to make you feel sleepy after taking the tablet, however all anti-histamines have the potential to cause drowsiness.
It can be purchased as the generic drug or as well-known brands such as Zirtek or Piriteze.
Who can and cannot take Cetirizine?
Cetirizine is generally safe and can be taken by adults and children over the age of 6. Children over the age of 2 can also take cetirizine but this would be via the liquid preparation as the dose would require to be reduced.
If you have any of the following, then you shouldn't take Cetirizine:
- If you have a confirmed or suspected allergic reaction to Cetirizine or any of the tablet's ingredients.
- If you have a confirmed allergy to E218 & E216.
- If you are intolerant to certain sugars (e.g. lactose, sorbitol).
- If you have a confirmed diagnosis of renal impairment.
- If you have a medical condition which can result in fits, e.g. epilepsy.
- Capsules can contain soya oil - do not take if you are allergic to peanuts or soya.
Pregnancy & Breastfeeding
Cetirizine is not known to be harmful and therefore can be taken during pregnancy. However, most manufacturers would advise avoiding the use of Cetirizine during pregnancy because of the limited studies that have been conducted on pregnant females. Loratadine is usually preferred in pregnant females as there is more data available.
Cetirizine is safe to use in breastfeeding mothers as the amount present in breast milk is very small.
If you are pregnant, think you may be pregnant and/or are breastfeeding, you should check with your GP if it is safe to start any new medication.
How to take Cetirizine?
You should take Cetirizine exactly as prescribed by your clinician. The usual dose for adults is 10mg daily (one tablet). Doses may need calculating if taking a liquid preparation.
The medication can be taken daily to prevent the symptoms of hay fever appearing. Alternatively, it can be taken on a when required basis only when symptoms present themselves. Never take a double dose.
What are the side effects of Cetirizine?
Like with all medication Cetirizine has the potential to cause some unwanted side effects. Common side effects can include drowsiness, dizziness, tiredness, headache, gastrointestinal issues, dry mouth, sore throat or cold like symptoms of the nose, and skin rash.
It is rare to develop a serious allergic reaction to Cetirizine. A full list of side effects can be seen in the patient information leaflet.
