Levocetirizine Dihydrochloride Mode of Action

Levocetirizine dihydrochloride is a second-generation antihistamine used to treat allergic conditions such as Hay-fever, urticaria, and allergic rhinitis.

The mechanism of action of levocetirizine dihydrochloride is to block histamine H1 receptors in the body, thereby reducing the effects of histamine.

Histamine is a substance produced by the body in response to an allergen or irritant, which causes various allergic symptoms such as itching, sneezing, runny nose, and watery eyes.

By blocking histamine receptors, levocetirizine dihydrochloride prevents histamine from binding to these receptors and causing allergic reactions.

This reduces symptoms such as itching, swelling, and inflammation.

Levocetirizine dihydrochloride is known for its high selectivity for H1 receptors. 

This means that it has minimal activity on other receptors in the body such as: B. Muscarinic, alpha-adrenergic, and serotonin receptors.

This makes it a safe and effective treatment for allergic symptoms with minimal side effects compared to first-generation antihistamines.


Levocetirizine Dihydrochloride Tablet Side Effects

Like all medications, levocetirizine dihydrochloride may cause side effects in some people. 

Here are some of the most common side effects of levocetirizine:



Dry mouth




Abdominal pain


Increased appetite

Muscle weakness

It’s important to talk to your doctor if you experience these side effects or other unusual symptoms after taking Levocetirizine Dihydrochloride.

In some cases, a serious allergic reaction may occur and immediate medical attention may be required.


What Drugs Should not be Taken with Levocetirizine Dihydrochloride

Levocetirizine Dihydrochloride can interact with other substances, including other drugs, supplements, and foods. Some potential interactions of levocetirizine are:

Central nervous system (CNS) depressants: Levocetirizine may enhance the effects of other CNS depressants, such as alcohol, sedatives, and tranquilizers, causing excessive sedation or drowsiness.

Cimetidine: Cimetidine, a medication used to treat ulcers, can increase the levels of levocetirizine in the blood, potentially leading to side effects.

Erythromycin and ketoconazole: These medications can also increase the levels of levocetirizine in the blood.

Rifampin: Rifampin, an antibiotic used to treat tuberculosis, can decrease the levels of levocetirizine in the blood, potentially reducing its effectiveness.

Fruit juices: Some fruit juices, such as grapefruit and orange juice, can inhibit the metabolism of levocetirizine, leading to increased blood levels and potentially causing side effects.


Is Levocetirizine Dihydrochloride Safe in Pregnancy

Levocetirizine Dihydrochloride is generally not recommended during pregnancy, especially in the first trimester, unless the potential benefits to the mother outweigh the potential risks to the fetus.

Although data on the safety of levocetirizine during pregnancy are limited, animal studies have shown adverse effects on fetal development and growth, including decreased fetal weight, delayed skeletal ossification, and increased risk of fetal abnormalities.

Therefore, if you are pregnant or plan to become pregnant, you should consult your doctor before taking levocetirizine or any other allergy medicine.

They will evaluate your individual case and recommend safer alternative treatment options during pregnancy, such as intranasal corticosteroids and saline nasal irrigation.

Is Levocetirizine Dihydrochloride Safe for Liver and Kidney Patients

Because Levocetirizine Dihydrochloride is primarily excreted by the kidneys, people with kidney disease may need dose adjustments and monitoring of kidney function while taking this drug.

In general, lower starting doses or longer dosing intervals may be recommended for patients with moderate to severe renal impairment.

Because Levocetirizine Dihydrochloride is partially metabolized in the liver, dose adjustments of levocetirizine may be necessary in patients with liver disease.

However, the degree of adjustment depends on the severity of the liver disease, and in some cases the drug may not be recommended at all.

Therefore, it is important to consult your doctor before taking levocetirizine if you have liver or kidney disease.


Why Do You Take Levocetirizine Dihydrochloride at Night

Taking Levocetirizine Dihydrochloride at night may be beneficial for several reasons:

Improved sleep: Levocetirizine can cause drowsiness as a side effect, especially when first starting it.

Taking the medication at night can help minimize this side effect and improve sleep quality.

Better control of morning allergy symptoms: By taking levocetirizine in the evening, it will have time to be most effective in the morning, when allergy symptoms are usually worst.

Convenient dosing: Taking levocetirizine at night may be more convenient for some people because they may take it along with other nighttime medications, such as sleeping pills or other medical conditions.

However, it’s important to note that levocetirizine can be taken at any time of day, depending on personal preference and when allergy symptoms appear.

Is Levocetirizine Dihydrochloride Good for Cold and Cough

Levocetirizine Dihydrochloride is mainly used to treat allergy symptoms, such as sneezing, runny nose, and itchy or watery eyes caused by an allergic reaction.

It works by blocking the action of histamine, a chemical released during an allergic reaction, thereby reducing or preventing allergy symptoms.

However, Levocetirizine Dihydrochloride  is not usually used to treat colds or coughs, as these conditions are more often caused by a viral infection than an allergic reaction.

In fact, using Levocetirizine Dihydrochloride to treat cold and cough symptoms may not be effective and may even be harmful because it can cause drowsiness, dry mouth, and other side effects.

If you have a cold or cough, it’s best to see your healthcare provider to determine the underlying cause of your symptoms and discuss appropriate treatment options.

They may also recommend home remedies, such as rest, rehydration, and steaming to help relieve your symptoms.

Which is Stronger Cetirizine or Levocetirizine

Both cetirizine and levocetirizine are second-generation antihistamines used to treat allergy symptoms, such as sneezing, runny nose, and itchy or watery eyes.

Both drugs work by blocking the action of histamine, a chemical released during an allergic reaction, thereby reducing or preventing allergy symptoms.

Levocetirizine is a stronger and more selective form of cetirizine.

This means that levocetirizine has a higher binding affinity for histamine receptors in the body, leading to a greater effectiveness in treating allergy symptoms and less risk of side effects such as drowsiness and safety.

In general, levocetirizine is considered to be slightly more effective than cetirizine in treating allergy symptoms, especially when it comes to relieving nasal congestion. 

However, both drugs are effective in treating allergy symptoms and have similar safety profiles.

It’s important to note that each individual’s response to the drug can vary, and some people may find cetirizine to work better for them than levocetirizine or vice versa.
