Choosing Generic Vs Branded Piriteze Tablets


Generic medicines contain the same active ingredient and are equally effective and medically equivalent as the branded products but are available at a lower price. Generic manufacturers have to demonstrate that they are medically identical to the branded product - i.e. they offer the same quality, strength, stability and effectiveness.

Generic medicines are required meet the same standards of safety, quality and efficacy as the branded medication. To receive market approval from the European Medicines Agency and MHRA, a generic medicine must be 'bioequivalent' to the originator product.

What is Cetirizine?

Cetirizine  is an antihistamine. It helps to relieve the symptoms of allergies, such as hay fever, hives and eczema. 

How does Cetirizine work?

Cetirizine reduces the amount of histamine your body produces during an allergic reaction, which helps to relieve symptoms such as itching, swelling and sneezing.

Cetirizine  is a tablet that should be taken once daily to help manage hay fever symptoms. It can be taken with or without food. 

When can I expect to see results?

Cetirizine should get to work quickly, so you should expect to see results within the first day of taking it.

Hay Fever Information

What is Hay Fever?

Hay fever (seasonal allergic rhinitis) is an allergic reaction that causes inflammation of the inside of the nose. It's a very common condition, estimated to affect around 1 in every 5 people in the UK.

What causes Hay Fever?

Hay fever is caused by allergens such as pollen or dust, which leads to inflammation and symptoms such as sneezing, a runny nose or watering eyes. 

You may find you react to different pollens throughout spring and summer. Tree pollen affects people between March and May, and grass pollen between June and July. Weed pollen is less common, but can occur between July and September.

What treatments are available for Hay Fever?

There are several options to help treat hay fever. Daily antihistamine tablets will help to manage most symptoms, and nasal sprays and eye drop solutions can also be used to treat specific areas of irritation. 

During hay fever season, it’s important to take an antihistamine tablet daily to manage your symptoms during this time.

Side Effects

What side effects may I experience?

You might experience some drowsiness, nausea or a dry mouth. These are uncommon side effects, and normally happen in the first few days of taking Cetirizine.

Another rare side effect that can occur with Cetirizine is a fast heart rate. If this happens, you should stop taking this medicine and contact 111 or your GP for further advice.  

Is there anybody who should not use Cetirizine?

Cetirizine is not recommended for breastfeeding women to take. It is also unsuitable for patients with kidney problems.
