What Are Loratadine Tablets and How Do They Relieve Allergies?
If sneezing fits, itchy eyes, and a constantly runny nose are making your day miserable, you are not alone. Hayfever affects around one in five people in the UK, and allergic reactions to dust mites, pet dander, and mould can cause similar misery year-round. Loratadine tablets offer once-daily, non-drowsy relief from these symptoms, making them one of the most widely used antihistamines available over the counter. You can browse the full range of treatments in our allergy and hay fever collection if you want to compare your options.
Each tablet contains 10mg of loratadine as the active ingredient. Loratadine is a second-generation antihistamine, which means it was specifically developed to reduce the sedating effects associated with older antihistamines like chlorphenamine. It is licensed in the UK for the relief of symptoms associated with allergic rhinitis — including hayfever — and chronic idiopathic urticaria (hives).
How Do Loratadine Tablets Work to Block Allergy Symptoms?
When your body encounters an allergen — pollen, dust, or animal fur, for example — your immune system releases a chemical called histamine. Histamine binds to H1 receptors throughout the body, triggering the familiar cascade of allergy symptoms. Loratadine works by selectively blocking those H1 receptors, preventing histamine from binding and stopping the reaction before it starts.
- Loratadine is absorbed quickly after oral ingestion, with peak plasma concentrations typically reached within 1–2 hours.
- It has a long half-life, allowing a single 10mg dose to provide up to 24 hours of symptom relief.
- Because loratadine does not readily cross the blood-brain barrier, it causes significantly less sedation than first-generation antihistamines.
- It does not impair psychomotor performance at standard doses, meaning most people can drive and operate machinery normally.
Who Is Suitable for Loratadine Tablets?
Loratadine tablets are suitable for a wide range of people. They are appropriate for adults and children aged 2 years and over, though the dosage differs by age and weight in younger children. They are particularly useful for people who need to remain alert during the day — students, drivers, and those in work environments where concentration matters.
- Adults and adolescents aged 12 and over experiencing hayfever or allergic rhinitis.
- Children aged 2–11 years (dose adjusted by weight — see dosage section).
- People with chronic idiopathic urticaria (persistent hives without a known cause).
- Those who have experienced drowsiness with older antihistamines and want a non-sedating alternative.

Frequently Asked Questions
Where can I buy loratadine tablets online in the UK?
You can buy loratadine tablets online in the UK from Cured Pharmacy, a GPhC-registered online pharmacy, without a prescription. They are classified as a General Sale List (GSL) medicine, meaning they are available over the counter. Browse our full allergy and hay fever collection for more options.
How do loratadine tablets work in the body?
Loratadine works by selectively blocking peripheral H1 histamine receptors, which prevents histamine from triggering allergy symptoms such as sneezing, itching, and a runny nose. It is a second-generation antihistamine, so it does not readily cross the blood-brain barrier. This means it causes far less drowsiness than older antihistamines like chlorphenamine.
How do I take loratadine tablets step by step?
Adults and children aged 12 and over should take one 10mg tablet once daily, swallowed whole with a glass of water. You can take it with or without food, at any time of day that suits your routine. Do not take more than one tablet in any 24-hour period.
What is the best time of day to take loratadine tablets?
Because loratadine is non-drowsy, it can be taken at any time of day — morning, afternoon, or evening. Many people prefer to take it in the morning so that it provides protection throughout the day during hayfever season. Consistency matters more than timing, so try to take it at the same time each day.
What are the common side effects of loratadine tablets?
The most commonly reported side effects of loratadine include headache and dry mouth. Some people may also experience mild fatigue, though this is less frequent than with older antihistamines. If you notice any unusual or severe symptoms, stop taking the tablets and speak to your pharmacist or GP.
How do I manage side effects of loratadine tablets?
Dry mouth can be managed by drinking plenty of water and staying hydrated throughout the day. Headaches are usually mild and can be relieved with standard over-the-counter pain relief if needed — you can find suitable options in our pain relief collection. If side effects persist or worsen, consult your pharmacist.
Who is eligible to take loratadine tablets?
Loratadine tablets are suitable for adults and children aged 2 years and over. They are particularly well suited to people who need to remain alert during the day, such as drivers, students, and those in active work roles. People with severe liver impairment, or those who are pregnant or breastfeeding, should consult a pharmacist or GP before use.
What happens if I miss a dose of loratadine?
If you forget to take a dose, take it as soon as you remember — unless it is nearly time for your next scheduled dose. In that case, skip the missed dose and continue as normal. Never take two doses at the same time to make up for a missed one, as this increases the risk of side effects.
How does loratadine compare to cetirizine for hayfever?
Both loratadine and cetirizine are second-generation antihistamines that provide once-daily hayfever relief. Loratadine is generally considered to have a lower risk of drowsiness, while cetirizine may cause mild sedation in some individuals. The choice between them often comes down to personal response, so it is worth trying both under pharmacist guidance if one does not suit you.
Can I take loratadine tablets every day long term?
Loratadine can be taken daily throughout the hayfever season or for as long as allergy symptoms persist. For chronic conditions such as perennial allergic rhinitis or chronic idiopathic urticaria, longer-term daily use may be appropriate under pharmacist or GP guidance. If you have been taking it for more than a few weeks without improvement, seek medical advice.
Can I take loratadine tablets if I am pregnant?
The safety of loratadine during pregnancy has not been fully established, so it is important to speak to your GP or midwife before taking it if you are pregnant or trying to conceive. Your healthcare provider can weigh up the benefits and risks for your individual situation. Do not self-medicate during pregnancy without professional advice.
Can children take loratadine tablets?
Yes, loratadine is suitable for children aged 2 years and over, but the dose depends on the child's weight. Children aged 2–11 weighing 30kg or under should take 5mg once daily, while those over 30kg can take the full 10mg adult dose. Always check with your pharmacist if you are unsure about the correct dose for your child.
Does loratadine cause drowsiness?
Loratadine is classified as a non-drowsy antihistamine because it does not readily cross the blood-brain barrier at standard doses. However, a small number of people may still experience mild tiredness, particularly at higher doses. If you do feel drowsy after taking loratadine, avoid driving or operating heavy machinery until you know how it affects you.
What are the latest findings on loratadine for allergy relief?
Loratadine has been extensively studied since its introduction and remains one of the most widely recommended non-drowsy antihistamines in UK clinical guidelines. Current NHS guidance continues to support its use as a first-line treatment for allergic rhinitis and hayfever. No significant new safety concerns have emerged from recent post-marketing surveillance data.
What are the alternatives to loratadine tablets for hayfever?
Alternatives to loratadine include other second-generation antihistamines such as cetirizine and fexofenadine, as well as nasal corticosteroid sprays like beclometasone for more persistent nasal symptoms. Eye drops containing sodium cromoglicate can help with allergic eye symptoms. You can explore a range of options in our allergy and hay fever collection.
