What are Piriton tablets?

Piriton tablets and syrup are effective treatments for hay fever and allergies in both children and adults. Piriton contains the antihistamine chlorphenamine, which quickly alleviates the uncomfortable symptoms of hay fever and other allergic reactions. This formula is considered a drowsy antihistamine, which can also help promote restful sleep. Each pack contains 60 tablets suitable for children and adults over 6 years old, or you can opt for a 150ml bottle of syrup, which is safe for use in children as young as 1 year.

Piriton Tablets are used to alleviate allergic symptoms associated with hay fever and other allergies. The active ingredient, chlorphenamine maleate, is an antihistamine that helps relieve symptoms of various allergies and itchy skin rashes.

 

What is the active ingredient in Piriton tablets?

The active ingredient in Piriton is chlorepheniramine 4mg.    

What is Piriton used for?

Piriton is an antihistamine that effectively relieves allergy symptoms such as a runny nose, sneezing, and watery or itchy eyes. It is also highly effective in soothing itchy, irritated, or inflamed skin. You can use Piriton to alleviate symptoms from the following:
  • Hay fever
  • Skin allergies and dermatitis
  • Pet allergies
  • Insect bites and stings
  • House dust, mould, or dust mite allergies
  • Nettle rash and hives
  • Heat rash
  • Mild food allergies
  • The itchy rash of chickenpox

How does Piriton work?

Piriton contains an antihistamine called chlorphenamine, which works by blocking the histamine receptors in the body. Histamine is a chemical released during an allergic reaction, responsible for triggering symptoms like itching, swelling, runny nose, and watery eyes. By preventing histamine from binding to its receptors, chlorphenamine effectively reduces and alleviates these allergic symptoms, helping to control the body’s allergic response and providing relief from discomfort. This makes Piriton a reliable treatment for various allergic conditions, including hay fever, skin reactions, and other common allergies.  

How to take Piriton?

The tablet can be divided into equal doses. For adults and children aged 12 years and over: Take one tablet every 4 to 6 hours as needed. Do not exceed 6 tablets in 24 hours. For children aged 6 to 12 years: Administer ½ tablet every 4 to 6 hours as needed. Do not exceed 6 half-tablets in 24 hours. For the elderly: Consult your doctor or pharmacist before taking this medication, as you may be more prone to side effects, including confusion, and you may need to take a lower daily dose. The maximum daily dose is 3 tablets (12 mg) within any 24-hour period.
  • Do not exceed the recommended dose.
  • Allow a minimum of 4 hours between doses.
  • Do not use continuously for more than 14 days without consulting a doctor.
  • Not suitable for children under 6 years of age.
If you take too many tablets: Seek immediate medical advice by contacting your doctor or the nearest emergency department. Avoid driving if you have taken an overdose. If you forget to take a dose: Take the missed dose as soon as you remember, unless it’s almost time for your next dose. Never double up on doses to make up for the missed one. If your symptoms persist, consult your doctor.
