What is Loratadine?

Loratadine 10mg tablets belong to a group of medicines known as antihistamines. Antihistamines work to relieve the symptoms of allergies for conditions like:

  • Hay fever
  • Eczema
  • Urticaria
  • Conjunctivitis

Loratidine is a non-drowsy antihistamine, meaning it is much less likely to make you feel tired after administration when compared to other antihistamines.

Loratadine is a prescription-only medicine (POM) that can be taken by adults and children over 2 years of age, although doses differ depending on your age.

It works by blocking the histamine chemical in your body, helping to prevent the symptoms of allergies.

What is Loratadine used to treat?

Loratadine is an antihistamine medicine used to treat the symptoms of allergies associated with conditions like hay fever, conjunctivitis, eczema and hives. It can also be taken for certain food allergies and reactions to insect bites.

Allergies are reactions that your body has to certain substances or food. They can occur in both adults and children. This is a common problem that is believed to affect at least 1 in 4 adults at some point during their lives. However, they are particularly common in children; many allergies will go away as children get older and their body builds up a natural tolerance, but in some cases they are lifelong.

In adulthood, it is possible to develop allergies to things you were not previously allergic to. Common allergies can include hay fever, food allergies, dust, latex, animal fur and household chemicals.

The main symptoms of allergies can include:

  • Sneezing
  • Itchy, red or watery eyes
  • Wheezing or coughing
  • A blocked, itchy or runny nose
  • Skin rashes
  • Tight chest, wheezing and shortness of breath
  • Swollen eyes or face
  • nausea or vomiting
  • diarrhoea
  • Dry or itchy skin

In more severe cases, an allergy can lead to a sever allergic reaction that would require immediate medical assistance. This is called anaphylaxis.

How does Loratadine work?

Loratadine works quickly to provide all-day relief from allergies. This non-drowsy antihistamine allows you to get on with your daily life without feeling tired as a result of taking it. This is an added benefit as many antihistamines are classed as “drowsy” antihistamines, meaning they have a sedative effect.

This antihistamine works by blocking a substance called histamine, which is a naturally-produced chemical in the body that is released when the body comes into contact with an allergen.

Histamine works to protect you from infections and other harmful issues, and is released by your body naturally. In most cases, it is a beneficial chemical for your health. However, when you come into contact with an allergy trigger, histamine causes the symptoms that come with the allergy to occur.

How to use Loratadine

Adults and children should take one 10mg tablet once a day.

Swallow the tablet whole with a glass of water.

Always read the patient information leaflet for comprehensive instructions. Follow your doctor’s dosage instructions and speak to them if you have any questions.

Who can take Loratadine?

Loratadine alternatives

While there is no complete cure for allergies, there are many medicines available to keep the symptoms under control. If Loratadine is not suitable for you, we stock a number of other antihistamine medicines, including Cetirizine (available as tablets and a liquid solution), Levocetirizine and Desloratadine. These medicines also work to block histamine from causing a flare-up of allergy symptoms.

Alternatively, a nasal spray such as Flixonase or Beclometasone may be more suitable for you. These sprays contain corticosteroid medicines, which will work to reduce inflammation in the nasal passages and also alleviate other symptoms of hay fever and allergies. Antihistamine nasal sprays are also available.

View the Hay Fever page on our website to see the full list of products for this problem.

You can also combat hay fever symptoms by:

  • Keeping doors and windows closed on days with high pollen counts
  • Wearing wrap-around sunglasses to stop pollen particles irritating your eyes
  • Showering when you come home to wash out any particles from your hair and skin
  • Using a pollen filter in your car
