Clarityne is an over-the-counter antihistamine medication that contains loratadine as its active ingredient. Each tablet typically contains 10 mg of loratadine and is used to relieve symptoms associated with allergies and hay fever.
Key Uses
Clarityne is indicated for the treatment of:
- Allergic Rhinitis: Relief from symptoms such as sneezing, runny or itchy nose, and itchy or watery eyes.
- Chronic Idiopathic Urticaria: Helps alleviate itching and hives.
Mechanism of Action
Loratadine works by selectively blocking peripheral H1 receptors, which prevents the action of histamine—a substance in the body that causes allergic symptoms. This makes Clarityne effective in reducing allergy-related symptoms without causing significant sedation.
Dosage and Administration
- Adults and Children (6 years and older): The usual dosage is 1 tablet (10 mg) once daily. It should not exceed this dosage within a 24-hour period.
- Children under 6 years: Not recommended; alternative formulations such as syrup may be more suitable.
Clarityne tablets can be taken with or without food. It is important to follow the prescribed dosage and not exceed the recommended amount.
Side Effects
Common side effects may include:
- Headache
- Drowsiness (though less likely compared to first-generation antihistamines)
- Dry mouth
- Fatigue
- Nervousness
Serious side effects are rare but can include:
- Allergic reactions (such as rash, hives, or difficulty breathing)
- Fast or uneven heart rate
Warnings and Precautions
- Contraindications: Not suitable for individuals with known hypersensitivity to loratadine or any of its components.
- Caution in Specific Populations: Use cautiously in patients with liver disease, as dosage adjustments may be necessary.
- Pregnancy and Breastfeeding: Consult a healthcare provider before use if pregnant or breastfeeding.
Storage
Store Clarityne tablets at room temperature (below 30°C), away from moisture and direct sunlight. Keep out of reach of children.
