What is Clarityn Allergy Syrup?

Clarityn Allergy Syrup is a treatment for symptoms of hay fever and other allergies, including pet fur and dust allergies. It’s suitable for adults and children aged 2 and over and has a yummy peach flavour that will mean there are no complaints when it’s time for your kids to take their allergy medicine. If you’re looking for an allergy treatment that can be used by the whole family, Clarityn syrup could be the perfect choice for you and your kids.

What happens when my child has hay fever?

When your child has hay fever, it means that they’re allergic to the pollen that’s produced by plants and released into the air. When they come into contact with pollen, their body responds to the irritant by producing a natural substance called histamine, which causes allergy symptoms. Histamine is released into different parts of the body, such as the eyes and nose, to trigger symptoms such as:

  • Sneezing

  • Red, watery eyes

  • Itchy eyes, ears, nose, or throat

  • Coughing

  • A blocked or runny nose

  • An itchy skin rash

How will the loratadine in Clarityn Syrup relieve my allergy symptoms?

Each 1ml of Clarityn Syrup contains 1mg of an active ingredient called loratadine, which is an antihistamine. Loratadine works by blocking the histamine produced in your body so it can’t trigger your allergy symptoms. It works quickly to block those symptoms at their source, offering treatment and protection that lasts all day long.

Can I give this medicine to my child if they’re taking other medications?

If your child is taking any other medication, including herbal remedies or medicines obtained without a prescription. This especially applies if you are taking medicines that affect your liver, as these can increase the potential side effects of Clarityn. 

Can adults take this treatment?

Adults can take Clarityn Syrup, and it’s ideal for adults who don’t like to take tablets or prefer liquid medicine. However, liquid medicines are often created with children in mind, so you may find Clatiryn tablets easier to take or generally more suitable for you. If you’re unsure, ask your doctor or pharmacist about your options and they’ll be able to help you choose the right allergy remedy for you.

Will this medicine make my child drowsy?

Clarityn Allergy Syrup is a non-drowsy allergy medicine, which means that it usually won’t make your child sleepy when they’ve taken it. However, in rare cases some people can become drowsy after taking this medicine, so be sure to monitor children carefully at all times. If you’re an adult who has taken this medicine, do not attempt to drive or use any tools or machinery if it makes you feel drowsy.

How much Clarityn Syrup should I give to my child?

The amount of Clarityn Syrup you should give to your child will depend on their age and weight. Use the measuring cup included to measure out the right amount before giving the medicine to your child.

  • Children aged 2 - 12 who weigh less than 30kg (4st 7lbs): 5ml once a day

  • Children aged 2 - 12 who weigh more than 30kg (4st 7lbs): 10ml once a day

  • Adults and children over 12: 10ml once a day
