AERIUS 5mg Tablets/Film-coated

What is AERIUS 5mg

AERIUS 5mg is a pharmaceutical preparation containing Desloratadine as its active ingredient, formulated as film-coated tablets. It belongs to the class of second-generation antihistamines and is widely prescribed for the treatment of allergic conditions.

• Active ingredient: Desloratadine 5 mg per tablet.
• Therapeutic use: It is primarily used to alleviate symptoms of allergic rhinitis (both seasonal and perennial) such as sneezing, nasal congestion, itchy and runny nose, as well as ocular symptoms like itchy and watery eyes.
• Additional indications: Effective for chronic idiopathic urticaria (hives) to reduce itching and rash.
• Non-sedating: Unlike first-generation antihistamines, AERIUS 5mg has minimal sedative effects because it selectively blocks peripheral H₁ receptors without significant penetration into the central nervous system.
• Convenient dosing: Once daily oral dosing due to its long half-life, improving patient compliance.
• Packaging: Available in blister packs of 20 tablets (10 tablets per blister × 2), suitable for short to medium-term treatment courses.

In summary, AERIUS 5mg tablets are a reliable and effective choice for managing allergy symptoms with a favorable safety profile.

How to use AERIUS 5mg

Using AERIUS 5mg tablets correctly is essential to maximize benefits and minimize side effects. Here are the key guidelines for use:

• Administration: Take the tablet orally with a glass of water.
• Timing: It can be taken with or without food, though consistency in timing each day is recommended.
• Dosage frequency: Typically, one tablet (5 mg) once daily is sufficient due to its long-acting nature.
• Missed dose: If a dose is missed, take it as soon as you remember. If it is close to the time for the next dose, skip the missed dose and continue as usual. Do not double the dose.
• Duration: Use for the duration advised by your healthcare provider. For seasonal allergies, it may be taken during allergy season, while chronic urticaria may require longer-term use.
• Special populations: Use with caution in elderly patients or those with kidney or liver impairment—consult your doctor for dose adjustments if necessary.
• Consultation: Inform your healthcare provider about all other medications or health conditions before starting treatment.

Following these instructions helps ensure safe and effective relief from allergic symptoms.

Mode of Action AERIUS 5mg

The pharmacological action of AERIUS 5mg centers on its active component, desloratadine, which targets the body's allergic response mechanisms:

• Histamine H₁ receptor antagonist: Desloratadine selectively binds to peripheral H₁-receptors, blocking histamine—a chemical mediator released during allergic reactions—from attaching to these receptors.
• Reduction of allergic symptoms: By inhibiting histamine binding, it prevents and alleviates common allergy symptoms such as itching, sneezing, runny nose, and swelling of the mucous membranes.
• Minimal CNS penetration: Its limited ability to cross the blood-brain barrier reduces sedation and drowsiness, making it preferable over first-generation antihistamines.
• Anti-inflammatory effects: Desloratadine also reduces the release of other inflammatory mediators, contributing to its efficacy in controlling chronic urticaria and prolonged allergic conditions.
• Pharmacokinetics: After oral administration, desloratadine is rapidly absorbed with peak plasma levels reached in about 3 hours. Its half-life of approximately 27 hours supports once-daily dosing.

This mechanism ensures sustained symptom relief with a good safety and tolerability profile.

AERIUS 5mg Interactions AERIUS 5mg

While AERIUS 5mg is generally safe and has a low interaction potential, awareness of possible drug interactions is important:

• Cytochrome P450 enzymes: Desloratadine is metabolized by CYP3A4 and CYP2D6. Strong inhibitors of these enzymes (e.g., ketoconazole, erythromycin, ritonavir) may increase desloratadine plasma levels, though clinical significance is often limited.
• Other antihistamines: Concurrent use with other H₁-antihistamines is not recommended as it may increase the risk of additive side effects.
• Alcohol and CNS depressants: Although desloratadine is less sedating, combining with alcohol or sedatives may still increase drowsiness or impairment in some individuals.
• Ritonavir and antivirals: These may increase desloratadine levels; dose adjustments or monitoring might be necessary.
• Other medications: Inform your healthcare provider of all other drugs, supplements, or herbal products to avoid unforeseen interactions.

Proper consultation ensures safe use alongside other therapies.

Dosage of AERIUS 5mg

The dosing of AERIUS 5mg tablets is straightforward but should be individualized based on patient factors:

• Adults and adolescents (12 years and older): The usual dose is one 5 mg tablet once daily.
• Children under 12 years: AERIUS 5 mg tablets are typically not recommended; pediatric formulations or doses should be used instead.
• Elderly patients: Usually no dosage adjustment is needed but monitor for tolerance.
• Renal or hepatic impairment: No routine dose adjustments necessary for mild to moderate impairment. In severe impairment, use with caution.
• Duration of therapy: Follow your doctor’s advice—seasonal allergic rhinitis may require short-term use, while chronic urticaria may need longer-term management.
• Missed dose: If a dose is missed, take it as soon as possible unless it is close to the next dose time.

Adherence to prescribed dosing helps optimize symptom control and minimizes risk.

Possible side effects of AERIUS 5mg

AERIUS 5mg is generally well tolerated. However, some side effects may occur, mostly mild and temporary:

• Common side effects:
  • Headache
  • Fatigue or mild drowsiness
  • Dry mouth
  • Nausea
  • Sore throat
• Less common side effects:
  • Dizziness
  • Abdominal discomfort or pain
  • Weight changes (rare)
• Rare but serious side effects:
  • Allergic reactions such as rash, itching, swelling, or difficulty breathing
  • Palpitations or irregular heartbeat
  • Severe headache or neurological symptoms
• Actions if side effects occur: If serious side effects or signs of an allergic reaction appear, stop medication and seek medical help immediately.

Reporting side effects to your healthcare provider ensures safe ongoing treatment.

AERIUS 5mg Contraindications AERIUS 5mg

There are specific conditions and situations where AERIUS 5mg should not be used:

• Known hypersensitivity: Allergy to desloratadine, loratadine, or any excipients in the tablet formulation.
• Severe renal or hepatic impairment: Use caution or avoid if liver or kidney function is significantly compromised.
