Alavert: Fast-Acting, Non-Drowsy 24-Hour Allergy Relief
Alavert
Alavert (loratadine) is a second-generation antihistamine specifically formulated to provide effective, 24-hour relief from seasonal and perennial allergy symptoms without the sedative effects commonly associated with older antihistamines. As an over-the-counter medication, it offers a convenient and reliable solution for managing allergic rhinitis and chronic idiopathic urticaria. Its active metabolite, desloratadine, works by selectively antagonizing peripheral H1 receptors, minimizing central nervous system penetration. This profile makes it a first-line recommendation for patients seeking to maintain alertness and cognitive function while controlling allergic responses.
Features
- Contains 10 mg of loratadine, a potent second-generation antihistamine.
- Formulated for rapid disintegration and absorption (orally disintegrating tablets available).
- Provides full 24-hour symptom control with a single daily dose.
- Non-drowsy formula is designed to minimize central nervous system effects.
- Available in various OTC forms, including standard tablets and syrup for pediatric use.
- Sugar-free and dye-free options are available for specific patient needs.
Benefits
- Sustained Symptom Relief: Effectively reduces sneezing, rhinorrhea, itchy/watery eyes, and nasal pruritus for a full day, improving quality of life.
- Cognitive Clarity: The non-sedating property allows for unimpaired daytime alertness and performance, making it suitable for drivers, students, and professionals.
- Rapid Onset of Action: Clinical effects are often noticeable within the first 1-3 hours post-administration, providing relatively quick relief.
- Convenient Dosing: A single daily dose enhances adherence and simplifies allergy management regimens.
- Minimal Anticholinergic Effects: Unlike first-generation antihistamines, it has a low affinity for muscarinic receptors, reducing side effects like dry mouth and urinary retention.
- Pediatric Formulations: Availability of a grape-flavored syrup allows for accurate weight-based dosing in children aged 2 years and older.
Common use
Alavert is indicated for the relief of symptoms associated with seasonal allergic rhinitis (hay fever), such as sneezing, rhinorrhea, pruritus of the nose/palate/throat, and ocular itching and burning. It is also indicated for the management of perennial allergic rhinitis and for the treatment of uncomplicated skin manifestations of chronic idiopathic urticaria (hives), reducing the size and number of wheals and relieving pruritus. It is not indicated for the treatment of asthma, anaphylaxis, or other systemic allergic reactions.
Dosage and direction
- Adults and children 6 years and older: The recommended dose is 10 mg (one tablet or two teaspoonfuls [10 mL] of syrup) once daily.
- Children 2 to under 6 years: The recommended dose is 5 mg (one teaspoonful [5 mL] of syrup) once daily. Tablet formulations are not recommended for this age group.
- Children under 2 years: A dosing recommendation has not been established. Consult a physician.
- Administration: Standard tablets can be taken with or without water. Orally disintegrating tablets should be placed on the tongue and will disintegrate within seconds, after which they may be swallowed with or without water. They should be taken on an empty stomach for optimal absorption.
- Dosing may be adjusted in patients with severe hepatic impairment; a reduced dose of 10 mg every other day is recommended.
Precautions
- Patients with liver or kidney impairment should use Alavert with caution and may require dosage adjustment; consult a healthcare provider.
- While classified as non-drowsy, individual responses can vary. Patients should observe their response to the medication before engaging in activities requiring full alertness, such as driving or operating machinery.
- The orally disintegrating tablets contain phenylalanine (a component of aspartame); caution is advised in patients with phenylketonuria (PKU).
- Use during pregnancy or breastfeeding should only be undertaken if the potential benefit justifies the potential risk to the fetus or infant. Loratadine is excreted in breast milk.
- Do not use Alavert for the self-treatment of a persistent cough, such as that associated with smoking, asthma, chronic bronchitis, or emphysema, or where cough is accompanied by excessive phlegm (mucus), without consulting a doctor.
Contraindications
Alavert is contraindicated in patients with a known hypersensitivity to loratadine, desloratadine, or any of the inactive ingredients in its formulations (e.g., lactose, magnesium stearate, corn starch, aspartame).
Possible side effect
While generally well-tolerated, the following side effects have been reported. In most cases, they are transient and mild.
- Common (>1/100): Headache, somnolence (though significantly less than with first-generation agents), fatigue, dry mouth.
- Uncommon (1/100 to 1/1000): Nervousness, dizziness, increased appetite, nausea, gastritis, palpitations, tachycardia, rash, alopecia.
- Rare (<1/1000): Hypersensitivity reactions (including anaphylaxis, angioedema, bronchospasm, urticaria, pruritus), seizures, hepatic dysfunction (including hepatitis and jaundice).
Drug interaction
Loratadine is primarily metabolized by the cytochrome P450 3A4 and 2D6 enzyme systems. Concomitant use with potent inhibitors of these enzymes may increase plasma concentrations of loratadine, potentially increasing the risk of side effects.
- Potent CYP3A4 Inhibitors: Ketoconazole, erythromycin, clarithromycin, cimetidine, ritonavir, grapefruit juice. Co-administration is not recommended.
- CNS Depressants: While the sedative potential is low, a theoretical additive effect with alcohol or other CNS depressants (e.g., benzodiazepines, opioids) exists.
- No clinically significant interactions have been demonstrated with warfarin, cimetidine (a weak inhibitor), or erythromycin (at standard doses).
Missed dose
If a dose is missed, it should be taken as soon as remembered. However, if it is almost time for the next scheduled dose, the missed dose should be skipped, and the regular dosing schedule resumed. Do not take a double dose to make up for a missed one.
Overdose
Symptoms of overdose may be an exaggeration of known side effects, including drowsiness, tachycardia, and headache. In the event of a suspected overdose, seek immediate medical attention or contact a Poison Control Center. General supportive and symptomatic measures are recommended. Gastric lavage may be considered shortly after ingestion. Loratadine is not effectively removed by hemodialysis.
Storage
Store Alavert at room temperature, between 20°C to 25°C (68°F to 77°F). Keep the medication in its original blister pack or bottle to protect it from light and moisture. Keep all medications out of the reach of children and pets. Do not use after the expiration date printed on the packaging.

Reviews
- “As an allergist, I frequently recommend loratadine as a first-line OTC option for my patients with mild to moderate allergic rhinitis. Its efficacy and safety profile are well-established, and the lack of sedation is a significant advantage for most.” – Dr. E. Vance, MD
- “I’ve suffered from severe hay fever for years. First-generation antihistamines made me too tired to function. Switching to Alavert was a game-changer; I get relief all day long without any drowsiness. It’s a staple in my medicine cabinet from spring through fall.” – Michael T.
- “The pediatric syrup is a lifesaver for my 4-year-old during allergy season. It’s easy to administer, and he doesn’t fight the grape flavor. Most importantly, it stops his constant sneezing and itchy eyes without making him sleepy or irritable.” – Sarah L.
- “Clinical trial data consistently shows loratadine’s superiority over placebo and its non-inferiority to other second-generation antihistamines for core allergy symptoms. Its OTC status and favorable side effect profile make it a cornerstone of allergic disease management.” – Clinical Pharmacologist Review
