What Are Cetirizine One a Day Tablets?
If you struggle with sneezing fits, a constantly runny nose, or itchy, watery eyes every time pollen season arrives, you are far from alone. Hay fever affects around 1 in 5 people in the UK at some point in their lives, according to the NHS. Cetirizine one a day tablets — sold here as Piriteze One A Day Tablets — offer a straightforward, once-daily solution to keep those symptoms under control. Each pack contains 30 tablets, giving you a full month's supply for just £8.99. You can browse our full range of allergy and hay fever treatments if you need additional support alongside your antihistamine.
Piriteze One A Day Tablets contain cetirizine hydrochloride 10mg as the active ingredient. Cetirizine is a second-generation antihistamine, which means it is far less likely to cause the heavy sedation associated with older antihistamines like chlorphenamine. It is licensed in the UK as a Pharmacy (P) medicine, available without a prescription for adults and children aged 6 and over.
How Do Piriteze One A Day Tablets Work?
When your body encounters an allergen — pollen, pet dander, dust mites, or mould spores — your immune system releases a chemical called histamine. Histamine binds to H1 receptors throughout the body, triggering the familiar cascade of allergy symptoms. Cetirizine works by selectively blocking those H1 receptors, stopping histamine from causing its effects.
- Cetirizine is rapidly absorbed after oral administration, reaching peak plasma concentration within one hour.
- It has a long half-life of approximately 10 hours, which is why a single daily dose is sufficient.
- Unlike first-generation antihistamines, cetirizine has limited penetration of the blood-brain barrier, reducing the risk of sedation.
- Symptom relief typically begins within 20–60 minutes of taking the tablet.
Who Should Use Piriteze One A Day Tablets?
These tablets are suitable for a wide range of people dealing with allergic conditions. They are particularly useful if you need reliable, all-day relief without the sedating effects of older antihistamines. That said, they are not appropriate for everyone — always read the label and check with your pharmacist if you are unsure.
- Adults and children aged 6 years and over with seasonal or perennial allergic rhinitis (hay fever).
- People experiencing chronic idiopathic urticaria (hives) or allergic skin reactions.
- Those who need to remain alert during the day — for example, drivers or people operating machinery (provided they are not affected by drowsiness).
- Individuals looking for a convenient once-daily antihistamine rather than multiple doses throughout the day.

Frequently Asked Questions
Where can I buy Piriteze One A Day Tablets online in the UK?
You can order Piriteze One A Day Tablets (30 tablets) directly from Cured Pharmacy for £8.99, with no prescription required. They are also available from high street pharmacies and supermarkets across the UK. Buying online is convenient if you want to stock up ahead of hay fever season without leaving home. Browse our full allergy and hay fever collection for additional options.
How do Piriteze One A Day Tablets work in the body?
Piriteze contains cetirizine hydrochloride, which selectively blocks H1 histamine receptors throughout the body. When you encounter an allergen, your immune system releases histamine — cetirizine prevents histamine from binding to those receptors and triggering symptoms. This is why it relieves sneezing, itching, runny nose, and watery eyes. Because it is a second-generation antihistamine, it is far less likely to cause sedation than older alternatives.
How do I use Piriteze One A Day Tablets step by step?
Take one tablet (10mg) once daily, swallowed whole with a glass of water. You can take it with or without food — it does not significantly affect how the medicine is absorbed. Try to take it at the same time each day to keep symptom relief consistent throughout the day.
What is the best time of day to take Piriteze One A Day Tablets?
There is no single "correct" time — the most important thing is consistency. However, if you find the tablets make you feel slightly drowsy, taking them in the evening may suit you better. If you need daytime allergy relief and do not experience drowsiness, a morning dose works well. Speak to your pharmacist if you are unsure what timing suits your lifestyle.
Are Piriteze One A Day Tablets non-drowsy?
Cetirizine is classified as a non-drowsy antihistamine because it has limited ability to cross the blood-brain barrier compared to first-generation antihistamines. That said, a small number of people do experience mild drowsiness. If you feel affected, avoid driving or operating heavy machinery until you know how the medicine affects you.
Can I take Piriteze One A Day Tablets every day long-term?
Cetirizine can be taken daily throughout the allergy season, and many people use it continuously for several months without problems. If you find you need it year-round, it is worth discussing this with your GP to rule out any underlying conditions. Long-term use is generally considered safe at the recommended dose, but medical review is advisable for extended courses.
What are the side effects of Piriteze One A Day Tablets and how do I manage them?
The most common side effects include drowsiness, dry mouth, headache, and fatigue — these are usually mild and often improve after the first few days. Staying well hydrated can help with dry mouth, and taking the tablet in the evening may reduce the impact of any drowsiness. If side effects persist or feel severe, stop taking the tablets and speak to your pharmacist or GP.
Who is eligible to take Piriteze One A Day Tablets?
These tablets are suitable for adults and children aged 6 years and over who have hay fever, allergic rhinitis, or chronic urticaria. They are not suitable for people with severe kidney impairment, those allergic to cetirizine or hydroxyzine, or children under 6. Pregnant or breastfeeding women should consult their GP before use.
What happens if I miss a dose of Piriteze One A Day Tablets?
If you forget to take your tablet, take it as soon as you remember — unless it is nearly time for your next dose. In that case, simply skip the missed dose and continue as normal. Never take two tablets at once to compensate for a missed dose, as this increases the risk of side effects without providing additional benefit.
Can I drink alcohol while taking Piriteze One A Day Tablets?
It is advisable to avoid alcohol while taking cetirizine, as alcohol can increase the risk of drowsiness and impair your ability to drive or concentrate. Even though cetirizine is classed as non-drowsy, combining it with alcohol may amplify any sedative effect. If you do choose to drink, do so in moderation and be aware of how you feel.
Can I take Piriteze One A Day Tablets during pregnancy?
The safety of cetirizine during pregnancy has not been fully established, so you should always consult your GP or midwife before taking it if you are pregnant or trying to conceive. The same applies if you are breastfeeding, as cetirizine may pass into breast milk. Your doctor can advise on the safest option for managing allergy symptoms during pregnancy.
What are the alternatives to Piriteze One A Day Tablets?
Common alternatives include loratadine (e.g. Clarityn), fexofenadine (e.g. Telfast), and acrivastine (e.g. Benadryl Allergy Relief). Each has a slightly different side effect profile and onset time — for example, loratadine is considered to have an even lower sedation risk than cetirizine. You can explore our ear, nose and throat range for nasal sprays and other allergy relief options.
How long does it take for Piriteze One A Day Tablets to start working?
Most people notice symptom relief within 20 to 60 minutes of taking a cetirizine tablet. The full effect builds over the first few hours, and because of its long half-life, a single daily dose provides relief for up to 24 hours. If you are taking it for hay fever, starting a few days before your expected exposure to pollen can help establish consistent protection.
Can children take Piriteze One A Day Tablets?
Yes — Piriteze One A Day Tablets are suitable for children aged 6 years and over at the same 10mg once-daily dose as adults. For children under 6, a different cetirizine formulation (such as an oral solution) at a lower dose may be more appropriate — always consult your pharmacist or GP. Do not give these tablets to children under 6 years of age.
What does the latest research say about cetirizine for hay fever?
Cetirizine remains one of the most widely studied second-generation antihistamines, with decades of clinical evidence supporting its efficacy and safety for allergic rhinitis and urticaria. Current NHS and NICE guidance continues to recommend it as a first-line treatment for hay fever alongside intranasal corticosteroids for moderate-to-severe symptoms. Research consistently shows it is well tolerated and effective for both seasonal and perennial allergic conditions.
