Buy Desloratadine

Desloratadine tablets are a hay fever and allergy treatment that can help you to keep your symptoms under control when you come into contact with an allergen. These tablets work as non-drowsy antihistamines, ideal for those who find that other allergy medications make them sleepy and interfere with their day to day life. These tablets can be taken by those aged 12 and over, so if you’re an adult or the parent of a teen who has hay fever or allergies to pet fur, dust, foods, or anything else, you may find that desloratadine is right for you.

How does desloratadine treat my allergy symptoms?

Desloratadine is an antihistamine, which means it combats the histamine that is released in your body when you have an allergic reaction. It blocks histamine, keeping it from triggering allergy symptoms in your eyes, ears, nose, throat, skin, and more. This effectively helps you to manage your allergies, offering a reliable way to keep your symptoms under control.



Take one desloratadine 5mg tablet a day, swallowing it with a sip of water. You can take the tablet with or without food, depending on your personal preference. Do not take more than one tablet a day and be sure to follow any dosage instructions given to you by your doctor.

Like all medications, desloratadine can have side effects, although not everyone will experience them. If you experience any of the following side effects then you may be having a severe allergic reaction to this medication and should seek medical help right away:

  • An itchy skin rash

Pregnancy and Breastfeeding Warning

Desloratadine tablets are not recommended for those who are pregnant or breastfeeding. If you suffer from allergies and need treatments that can help you manage your symptoms during your pregnancy we’d recommend speaking to your doctor or pharmacist. They can recommend suitable treatments for you as well as lifestyle changes that can help you to keep your symptoms under control until you can take your regular allergy relief medication again.

Alcohol Warning

You should take care while drinking alcohol with desloratadine tablets, as it can make side effects more likely. For example, you are more likely to feel drowsy or dizzy if the two interact. We’d recommend avoiding alcohol as much as possible while you’re taking these tablets, as this is the only way to keep them from causing unwanted side effects.

Other Medication

There are currently no known interactions between desloratadine and any other medications, which means that you should be able to take your usual medication alongside this treatment. However, if you are taking any other medications, including herbal remedies or medicines you obtained without a prescription, you should tell your prescriber about them during your consultation. They will be able to assess the medications you’re taking and help you to decide which allergy treatment will be the best choice for you.

Frequently Asked Questions

As desloratadine is a non-drowsy antihistamine you will usually be able to drive after taking these allergy tablets.

However, there is always a chance that you may experience symptoms like drowsiness or dizziness when you take this medication, so if you’re taking them for the first time you should make sure you don’t need to drive right away.

This will give you the chance to assess how your body reacts to this medication and whether you will be safe to drive.

If you experience any symptoms that affect your concentration, make you drowsy, or would affect your ability to drive in any way, don’t attempt to drive or use any tools or machinery until the symptoms have passed and you’re sure that you’re safe to do so.

Desloratadine is a non-drowsy antihistamine, which means it’s less likely to make you feel drowsy after you take it than other similar medicines.

This is because it’s a newer formula, as older antihistamines tend to make people feel drowsy when you’ve used them, which can sometimes make them difficult to take effectively.

If you find that older antihistamines, such as chlorphenamine and promethazine make you feel sleepy after you’ve used them, trying a non-drowsy formula like this one could be the ideal alternative for you.

Desloratadine and loratadine are very similar medications, both being used as a non-drowsy antihistamine for hay fever and allergy relief.

Desloratadine is the primary metabolite of loratadine, which means that the two both work in the same way to relieve your hay fever and allergy symptoms.

Some people prefer one medication over the other, as some find that desloratadine is a more effective treatment for them, but this can depend on the person, their allergies, and the types of treatments that work best for them.

If you’re unsure whether one or the other would be better for you, we’d recommend asking your doctor or pharmacist for advice.

You do need a prescription for this medication in the UK.

Our healthcare professionals can provide prescriptions if they think this treatment would be right for you and your condition.

When you click the button which reads “Start Consultation” at the top of this page, you’ll see a short questionnaire set up by our healthcare team which is designed to help them understand your medical needs.

Just like an in-person consultation with your GP, our doctors will assess your answers to their questions and write a prescription for the treatment they think will be best for you.

You’ll then be able to pay for your medication and we’ll send it out to you quickly and in discreet packaging.

Hayfever is a common allergic condition that affects up to one in five people.

It usually affects people in the spring and summer when plants start to release pollen, a fine powder let out by plants as part of their reproductive cycle.

The proteins in pollen can cause your nose, throat, eyes and sinuses to become swollen and inflamed.

The main three types of pollen that can trigger allergic reactions are tree pollen, grass pollen and weed pollen.

Symptoms of hay fever include: 

  • Sneezing and coughing
  • A runny or blocked nose
  • Itchy, red or watery eyes
  • Itchy throat, mouth, nose and ears
  • Loss of smell
  • Pain around the temples and forehead
