From the Guidelines
For throat itchiness from oral allergy syndrome while already taking Claritin, try adding a steroid nasal spray like fluticasone (Flonase) or triamcinolone (Nasacort), which can reduce inflammation in the throat area. You can also use throat lozenges containing benzocaine or menthol for temporary relief. Consider avoiding raw fruits and vegetables that trigger your symptoms, or try peeling or cooking them, as this often destroys the allergens 1. Drinking cold liquids or eating ice chips may provide immediate soothing relief. If Claritin isn't effective enough, discuss with your doctor about switching to a different antihistamine like cetirizine (Zyrtec) or fexofenadine (Allegra), which some people find more effective for oral allergy syndrome 1. These approaches work because oral allergy syndrome occurs when proteins in certain foods cross-react with pollen allergies, causing local inflammation.
Some key points to consider:
- Second-generation antihistamines, such as loratadine, are generally preferred over first-generation antihistamines due to their lower risk of sedation and anticholinergic effects 1.
- Among the second-generation antihistamines, no single agent has been conclusively found to achieve superior overall response rates 1.
- Steroid nasal sprays, such as fluticasone or triamcinolone, can be effective in reducing inflammation and relieving symptoms of allergic rhinitis, including throat itchiness 1.
- Avoiding triggers and using throat lozenges or cold liquids can provide temporary relief and help manage symptoms.
It's essential to consult with your healthcare provider if symptoms persist or worsen despite these measures, as you may need prescription-strength medication or further evaluation.
From the FDA Drug Label
INDICATIONS AND USAGESeasonal Allergic RhinitisFexofenadine Hydrochloride Tablets are indicated for the relief of symptoms associated with seasonal allergic rhinitis in adults and children 6 years of age and older. Symptoms treated effectively were sneezing, rhinorrhea, itchy nose/palate/throat, itchy/watery/red eyes.
The FDA drug label does not answer the question about what to do for throat itchiness with oral allergy syndrome while already taking Claritin (loratadine) 2.
From the Research
Managing Throat Itchiness with Oral Allergy Syndrome
If you are experiencing throat itchiness due to oral allergy syndrome and are already taking Claritin (loratadine), consider the following options:
- Identify and avoid trigger foods that cause your oral allergy syndrome symptoms, as suggested by studies on oral allergy syndrome 3
- Consider alternative antihistamines, such as fexofenadine, which have been shown to be effective in managing seasonal allergic rhinitis and chronic idiopathic urticaria 4
- Be aware of the potential for anaphylaxis, especially if you have a history of severe reactions, as noted in a study on oral allergy syndrome and anaphylaxis risk 5
Antihistamine Options
When choosing an antihistamine, consider the following:
- Second-generation antihistamines, such as loratadine, desloratadine, cetirizine, and fexofenadine, are generally preferred over first-generation antihistamines due to their lower risk of sedation and impairment 6
- Fexofenadine has been shown to be effective in relieving symptoms of seasonal allergic rhinitis, including sneezing, rhinorrhoea, and itchy throat 4
- Desloratadine, a new selective histamine H(1)-receptor antagonist, has potent antihistaminic and anti-inflammatory activity and may be effective in treating systemic aspects of allergic disease 7
Important Considerations
