Claritin
Claritin (which contains the drug loratadine) is a type of over-the-counter medicine known as a non-drowsy antihistamine. It is used in adults and children aged 2 years and above to relieve the symptoms of allergies in a wide range of allergic conditions, including hay fever, insect bites, pet allergies, food allergies, contact dermatitis, and atopic eczema. Claritin helps relieve itching, sneezing, runny nose, skin rash, and red/itchy/watery eyes and is available in tablet, disintegrating tablet (they melt in your mouth), and oral liquid forms.
Even though Claritin is classed as a non-drowsy antihistamine, it can still cause drowsiness in some people. If you do experience drowsiness, it is advised that you avoid driving or drinking alcohol.
What can you find here?
How much should I take
Adults and children over 6 are recommended to take 10 mg once a day. Children aged 2 to 6 are recommended to take 5 mg once a day.
How does it work?
During an allergic reaction, your immune system releases a chemical called histamine, which is responsible for the symptoms of an allergy. Antihistamines work by opposing the actions of histamine by stopping histamine binding to its target sites in the body.
The chemical structure of non-drowsy antihistamines makes them less likely to enter the brain through what is known as the blood-brain barrier. This makes them less likely to cause drowsiness compared to other antihistamines.
Who should not take the medication?
Claritin is not suitable for everyone. You should not take Claritin if you have previously had an allergic reaction to loratadine, desloratadine (a similar medicine), or another ingredient listed in the medicine. Claritin should not be given to children under 2 years of age.
You should speak with your doctor before taking Claritin if you have liver or kidney problems, are pregnant or breastfeeding, have epilepsy or are at risk of having convulsions, have a metabolic disorder called porphyria, are due to have an allergy skin test or have problems absorbing or are intolerant to lactose or other sugars, as it may not be suitable for you.
Diabetics or people with phenylketonuria need to be careful when taking liquid and disintegrating tablet forms of Claritin as they may contain sugar or aspartame; it may be best for them to avoid these formulations.
Claritin can interact with other medicines, such as certain antidepressants and ritonavir. If you take any prescription, over-the-counter or herbal medicines, we recommend you should speak with your doctor or pharmacist to check if they are safe to take alongside Claritin.
Are there any side-effects?
Not everyone will experience side effects, but common ones include - nervousness (particularly in children), headache, drowsiness, increased appetite, and insomnia.
As with all medications, there is the potential for serious side effects, such as an allergic reaction. You should stop taking Claritin and seek urgent medical attention if you develop a skin rash, shortness of breath, wheezing, tightness in your chest or throat, or swelling of your tongue, mouth, lips, face, or throat.
