Understanding Delarex: Your Guide to Allergy Relief

If you’ve been prescribed Delarex, this guide is here to help you understand the medication and its benefits. Delarex, containing desloratadine, is commonly used to relieve symptoms associated with allergies. Let’s delve into the details to make this information accessible and clear for everyone.

What is Delarex?

Delarex is an antihistamine medication that contains desloratadine as its active ingredient. It belongs to a class of medicines known as tricyclic histamine antagonists, specifically targeting H1-receptors. This medication is long-acting and is particularly effective in alleviating the symptoms of allergies.


Delarex is prescribed for the following conditions:

  • Relief of nasal and non-nasal symptoms of seasonal and perennial allergic rhinitis in patients 6 months of age and older.
  • Symptomatic relief of pruritus (itching), reduction in the number and size of hives in patients with chronic idiopathic urticaria 6 months of age and older.
  • Symptoms of allergic conjunctivitis.

Positive Impact of Delarex

Desloratadine, the active ingredient in Delarex, is a metabolite of loratadine. It effectively blocks the action of histamine, a substance in the body that causes allergic symptoms. Unlike some antihistamines, desloratadine does not cross the blood-brain barrier, making it non-sedating and suitable for everyday use.

Recommended Dosage

For adults and children 12 years of age and over, Delarex is available in tablet and syrup forms. The usual dosage includes:

  • Delarex tablet: One tablet to be taken once daily.
  • Delarex syrup: Two teaspoonfuls (5mg in 10 ml) to be taken once daily.

Dosages for children vary based on age, ranging from one teaspoonful of syrup for children aged 6 to 11 years to 2 ml (1 mg) for children 6 to 11 months of age. Patients with hepatic or renal impairment may be given Delarex 5 mg on alternate days initially.

Dealing with Side Effects

While Delarex is generally well-tolerated, some individuals may experience side effects. Common side effects may include pharyngitis, dry mouth, myalgia, fatigue, somnolence, dysmenorrhea, and low antimuscarinic effects. It’s important to note that these side effects are generally mild and temporary.

Practical Tips and Guidance

  • Consistent Use: Take Delarex consistently as prescribed by your healthcare provider for optimal effectiveness.
  • Monitoring Side Effects: Pay attention to any side effects and report them to your healthcare provider. Most side effects are mild and temporary.
  • Storage: Store Delarex tablets in their original packaging in a dry place, and the syrup should be stored at a temperature not exceeding 30°C.
  • Keep Out of Reach of Children: Ensure that the medication is stored out of reach of children.

Essential Precautions

Before taking Delarex, inform your healthcare provider if you are hypersensitive to desloratadine or any of the product ingredients. While rare, side effects such as tachycardia, palpitations, arrhythmias, and hypersensitivity reactions may occur. In case of an overdose, a little increase in QT with no clinically relevant adverse events was reported.

Disease or Condition Information
