What are Chlorphenamine 4mg Hayfever and Allergy Tablets?

These tablets are an antihistamine that can reduce the effects of symptoms caused by allergies such as hay fever. The active ingredient, chlorphenamine maleate, works to ease the effects of symptoms for several allergies, such as:

  • Hay fever
  • Rhinitis (nose irritation)
  • Urticaria (also known as hives or nettle rash)
  • Pruritus (itching)
  • Insect bites or stings
  • Food allergies
  • Pet allergies


Who are Chlorphenamine tablets suitable for?

Chlorphenamine tablets are perfect for those looking for an everyday way to relieve allergy symptoms. If you’re struggling with hay fever, or have a pet hair allergy that flares up whenever you see your friend’s dog, these tablets can help you to manage your symptoms whenever you need them most.


What symptoms will I experience if I have hay fever or an allergy?

If you have an allergy, such as hay fever, then there are some common symptoms you might notice when you’re having an allergic reaction. Some of the most recognisable allergy symptoms include:

  • Sneezing
  • Coughing
  • Itchy, red, or watery eyes
  • Itchy ears, mouth, throat, or nose
  • Runny or blocked nose


How will the Chlorphenamine Maleate 4mg in these tablets help to ease my hay fever or allergy symptoms?

These tablets contain the active ingredient Chlorphenamine Maleate, which is an antihistamine. When you come into contact with something you’re allergic to, like pollen, dust, or pet hair, then your body begins to create a substance called histamine. Histamine causes symptoms like sneezing and watery eyes as it tries to remove the allergen from your body. Antihistamines block histamine receptors, helping to prevent those symptoms from occurring right from the start.


Can I take these if I’m pregnant or breastfeeding?

If you are pregnant, think you may become pregnant, or are breastfeeding, you should speak to your doctor or pharmacist before taking this product. Do not take any medication before consulting a medical professional when you are pregnant or breastfeeding, just in case the product is not suitable for you or your baby.


Can I drive after taking these tablets?

These tablets can make you feel drowsy and may make your vision blurred after you’ve taken them. If you experience either of these side effects, do not attempt to drive, or operate any machinery or tools until this has completely passed and you are sure that you are safe to do so.


Can I take these tablets if I’m taking other medication?

If you’re taking any other medication, including herbal remedies or medicines obtained without a prescription, you should speak to your doctor or pharmacist before taking this product. This especially applies if you are already taking:

  • Phenytoin, which is used for epilepsy
  • Medications used to treat anxiety
  • Sedatives
  • Anticholinergic drugs, e.g. atropine, hyoscine
  • Betahistine, which is used to treat vertigo and hearing disturbances
  • Lopinavir, which is used to treat HIV


What is the usual dosage of this product?

Swallow your chlorphenamine tablet with a sip of water. The number of tablets you will need to take will change depending on your age:

  • Adults and children over the age of 12: One tablet every 4 – 6 hours. Do not take more than 6 tablets in 24 hours
  • Children aged 6 – 12 years: Half a tablet every 4 – 6 hours. Do not take more than 3 full tablets in 24 hours


When should this product not be used?

Chlorphenamine tablets are not suitable for use by children under the age of 6. Do not take this product if you are allergic to chlorphenamine or any of the other listed ingredients. Do not take this product if you:

  • Have taken monoamine oxidase inhibitors (MAOIs) within the past 14 days. These are used for depression and include Isocarboxazid (Marplan), Phenelzine (Nardil), and Selegiline (Emsam)
  • Have known brain damage or epilepsy
