Leveo citrizin 2
Quick fact
Levocetirizine is an antihistamine used to relieve allergy symptoms such as sneezing, runny nose, itching, and hives by blocking histamine.
Uses
What is Levocetirizine Tablet & Important Details
Levocetirizine is a second-generation antihistamine used to reduce symptoms caused by histamine during allergic reactions. It is commonly used for allergic rhinitis and chronic urticaria (hives). It can reduce itching, sneezing, a runny nose, and other allergy-related symptoms.
- Helps relieve sneezing and a runny or itchy nose caused by allergies.
- May reduce itching and watery eyes associated with allergic conditions.
- Used to control itching and hives associated with chronic urticaria.
- It is generally taken once daily when prescribed.
- Some people can experience sleepiness or tiredness after taking it.
How does Levocetirizine work (mechanism of action)?
Levocetirizine works mainly by blocking H1 histamine receptors. Histamine is one of the chemicals responsible for many allergy symptoms.
- An allergen triggers the release of histamine in the body.
- Histamine binds to H1 receptors in tissues.
- This contributes to symptoms such as itching, sneezing, runny nose, and hives.
- Levocetirizine blocks these H1 receptors.
- As a result, many histamine-related allergy symptoms become less noticeable.
Specialized or Off-Label Uses of Levocetirizine
Levocetirizine may sometimes be used by clinicians for allergy-related conditions beyond the specific indication listed on a particular product label. Such use should be based on the patient’s condition and medical advice.
- Allergic skin itching associated with certain allergic conditions.
- Other histamine-related symptoms when an antihistamine is considered appropriate.
- Allergic conditions where control of itching or sneezing is clinically required.
Conditions That Levocetirizine Will Not Treat
Levocetirizine controls histamine-related symptoms but does not treat every cause of similar symptoms.
- Bacterial infections such as bacterial pneumonia.
- Viral infections such as influenza or the common cold itself.
- Asthma attacks or severe breathing difficulty.
- Severe allergic reactions requiring emergency treatment.
- Fever caused by an infection.
- Underlying causes of non-allergic itching.
Benefits
What are the benefits of taking Levocetirizine Tablet
When appropriately used, levocetirizine can reduce several uncomfortable symptoms caused by histamine release.

- Reduces a runny or itchy nose.
- Helps control allergy-related itching.
- Can reduce symptoms of hives and skin itching.

Levocetirizine Dosage Guidelines
Overview
The appropriate dose depends on age, the condition being treated, and kidney function. Levocetirizine tablets may be available as 5 mg scored tablets, allowing a 2.5 mg dose where appropriate. :contentReference[oaicite:0]{index=0}
Adults
5 mg once daily in the evening; some patients may be adequately controlled with 2.5 mg once daily.
Children 6–11 years
2.5 mg once daily in the evening for applicable tablet dosing.
Older adults
Dose selection should consider kidney function because levocetirizine is mainly eliminated through the kidneys.
- The prescribed dose should not be exceeded.
- Age and the condition being treated affect dosing.
- Kidney function can require a lower dose or less frequent dosing.
- Other medicines and medical conditions may affect safe use.
- Children should receive only the dose appropriate for their age and formulation.
Do not calculate a child’s dose yourself. Follow the pediatrician’s instructions and the product-specific dosing information.
Dosage Adjustments for Kidney, Liver, or Other Health Problems
Because levocetirizine is substantially eliminated by the kidneys, reduced kidney function can increase exposure to the medicine and requires dose adjustment.
- Normal kidney function: Standard age-appropriate dosing may be used.
- Reduced kidney function: A lower dose or longer dosing interval may be required.
- Severe kidney impairment: Dosing must be substantially reduced according to creatinine clearance.
- Dialysis: Patients receiving hemodialysis should not receive levocetirizine under the cited U.S. tablet labeling.
- Liver disease: No adjustment is generally required for liver impairment alone, but combined kidney and liver disease requires careful assessment.
- Other conditions: Tell your doctor about urinary problems, seizure disorders, or other significant medical conditions.
Do not change the dose yourself when kidney function is reduced. :contentReference[oaicite:1]{index=1}
How Often and How Long to Take Levocetirizine?
Many patients take levocetirizine once daily, often in the evening. The duration depends on whether symptoms are occasional, seasonal, or persistent.
- Take it at the prescribed time each day.
- Do not take extra doses to obtain faster relief.
- Follow your doctor’s instructions about treatment duration.
- If symptoms continue despite treatment, discuss them with a healthcare professional.
How should I take Levocetirizine?
Taking Levocetirizine With or Without Food
Levocetirizine tablets can generally be taken with or without food. Take the medicine according to the directions on your prescription or product label. :contentReference[oaicite:2]{index=2}
How to Take Specific Forms (Tablets, Chewables, Liquid Suspension)
Tablets and capsules
Swallow the tablet with water. Do not take more than the prescribed amount. If your tablet is scored and your prescribed dose is 2.5 mg, use the product as directed rather than estimating a partial dose.
Chewable tablets
If a chewable formulation is prescribed, follow its specific product instructions and chew it as directed.
Liquid suspension
If you are using a liquid formulation, measure each dose with the supplied measuring device rather than a household spoon. Shake the product if its label instructs you to do so.
Overdose/Missed Dose
What should I do if I accidentally use too much Levocetirizine?
Taking too much levocetirizine may increase drowsiness and other adverse effects. Contact a healthcare professional or poison-control service for advice, particularly after a large or accidental overdose.
What should I do if I miss a dose of Levocetirizine?
Take the missed dose when you remember unless it is nearly time for your next dose. If the next dose is close, skip the missed dose and return to your regular schedule. Do not double the dose.
Interactions
Does Levocetirizine interact with foods or drinks?
Levocetirizine tablets can generally be taken with or without food. Alcohol is important to consider because it may increase sleepiness or impairment in some people.
Does Levocetirizine interact with other medicines (drug interactions)
Tell your doctor or pharmacist about all medicines you use. Medicines that cause drowsiness may increase the sedating effects of levocetirizine.
- Other antihistamines that cause drowsiness

- Medicines that depress the central nervous system
- Other medicines that may impair alertness
Levocetirizine and Blood Thinners
- Levocetirizine is not generally considered a blood thinner.

- Tell your healthcare professional about anticoagulants and all other medicines you take.
Levocetirizine and Birth Control (if applicable)
Levocetirizine is not known to reduce the effectiveness of hormonal birth control. However, patients should discuss pregnancy or contraception questions with their healthcare professional when other medicines are also being used.
Interactions with Supplements, Vitamins, and Herbal Products
Information about interactions between levocetirizine and many supplements or herbal products is limited.
- Tell your pharmacist about herbal sleep products.
- Report use of supplements that may cause drowsiness.
- Do not assume that “natural” products cannot interact with medicines.
- Alcohol-containing products may increase sedation.
- Ask before combining several products used for allergy or sleep symptoms.

Heart disease
Tell your doctor about significant heart disease and all medicines you use before starting treatment.
Safe Usage & Best Practices
Why You Must Complete the Full Prescription
Levocetirizine is not an antibiotic, so a fixed “full course” is not required in the same way as with antibiotics. Use it for the duration recommended for your allergy condition and do not continue unnecessarily without medical advice.
Consequences of Skipping Doses or Sharing Medication
Skipping a prescribed dose may allow allergy symptoms to return, while sharing medicine can expose another person to an inappropriate drug or dose.
- The other person may have a different medical condition.
- Kidney function and age can change the appropriate dose.

- Do not take extra doses when symptoms return.
- Ask if ongoing daily treatment is necessary.
- Discuss persistent or worsening symptoms with a healthcare professional.
Levocetirizine and Alcohol
