Levocetirizine Tablets

Levocetirizine is a second-generation antihistamine tablet used to relieve the symptoms of allergies. It's closely related to cetirizine but is considered a more refined, potent version of it. It's used to treat hay fever, allergic rhinitis (a runny or blocked nose caused by an allergy), hives (urticaria), and itchy skin reactions. It works by blocking histamine — the chemical your body releases when it reacts to an allergen — helping to ease symptoms like sneezing, a runny or itchy nose, watery eyes, and itchy or blotchy skin. It's available as a prescription medicine in the UK and can be ordered conveniently through Access Doctor following a short online consultation.

The standard dose for adults and children aged 6 and over is one 5mg tablet once a day. Levocetirizine is best taken in the evening, as it can cause drowsiness in some people — taking it at night means this is less likely to affect your day. You can take it with or without food, and it should be swallowed whole with a glass of water. Try to take it at the same time each evening to keep it working consistently. If you miss a dose, take it as soon as you remember — but if it's nearly time for your next dose, just skip the missed one and carry on as normal. Never take a double dose.

Levocetirizine can cause drowsiness in some people, particularly in the first few hours after taking it — which is why it's recommended to take it in the evening. However, clinical tests have shown that at the standard recommended dose, it does not significantly impair mental alertness or the ability to drive in most people. That said, everyone responds differently to medication, so it's important to see how levocetirizine affects you personally before driving or operating machinery. You should also avoid alcohol while taking it, as this can increase the risk of drowsiness and reduce your alertness.

Most people take levocetirizine without any issues. The most commonly reported side effects are feeling drowsy or tired, headache, and a dry mouth — these are usually mild and often settle within a few days. In rare cases, some people experience difficulty passing urine, so if you notice any problems urinating, contact your doctor promptly. A serious allergic reaction to levocetirizine is very rare, but if you experience swelling of the face, lips, tongue or throat, difficulty breathing, or a severe rash, stop taking it immediately and call 999 or go to your nearest A&E.

For most people, stopping levocetirizine is straightforward and causes no problems. However, in rare cases, some people experience intense itching when they stop taking it after long-term daily use — even if they didn't have itching before. If this happens to you, the itching usually settles on its own, but in some cases it may be necessary to restart the medication and reduce the dose gradually. If you experience this, speak to your GP or one of our clinicians at Access Doctor for advice.

If you have kidney problems, you may need a lower or less frequent dose of levocetirizine, as the medication is primarily processed and eliminated by the kidneys. People with severe kidney disease or those on dialysis should not take levocetirizine at all. If you have any degree of kidney impairment, it's essential to speak to your doctor before taking this medication so they can advise on a safe and appropriate dose for you.

Levocetirizine is not recommended during pregnancy or breastfeeding unless specifically advised by your doctor. There is limited data available on its safety in pregnant women, and it is not known whether it passes into breast milk in significant amounts. If you are pregnant, planning a pregnancy, or currently breastfeeding, speak to your GP before taking levocetirizine — they can advise on the safest antihistamine option for your circumstances.
