Loratadine and Allegra (fexofenadine) are antihistamines used for allergies, so they won't help lower a fever. While these allergy medications are generally very safe, minor side effects can include mild drowsiness, a dry mouth, or a headache. Serious side effects, though very rare, include severe dizziness, a rapid heartbeat, or an allergic rash. Please rest well, stay hydrated, and feel free to reach out to a healthcare provider if your fever persists.

Since the antifungal cream and Allegra haven't helped, the rash may not be fungal; it could be eczema or contact dermatitis. To help soothe his hands, try applying a thick, fragrance-free moisturizer or petroleum jelly frequently, and use cool, damp compresses to ease the itching. Please consult his pediatrician before continuing the Allegra, as 120 mg is a very high dose for a five-year-old. His doctor can safely evaluate the rash and may recommend a mild topical corticosteroid to help his skin heal.

Since your symptoms return quickly after stopping deflazacort and fexofenadine, it is important to find a safer, long-term solution. Prolonged steroid use can have side effects. Under a specialist's guidance, next steps often involve increasing your daily non-drowsy antihistamine (like fexofenadine) up to four times the standard dose. If this is still ineffective, advanced therapies such as a targeted biologic injection (omalizumab) or other immunomodulating medications can be highly effective. Please consult an allergist or dermatologist to safely transition off the steroid and find a personalized treatment plan.

It is generally very safe to take Allegra (fexofenadine) 180 mg once daily for a month to manage your symptoms. This medication is a non-drowsy antihistamine designed for daily use and does not typically build up in your system or cause serious long-term side effects. However, if you find you still need it after a month, or if your symptoms aren't improving, it is a good idea to check in with your doctor to explore other options.

The white patches and burning may be chemical irritation or a localized infection, and harsh rinses like Betadine or Listerine might actually be irritating the raw tissue further. Please stop using those for now and stick to gentle, warm salt-water rinses. Because fexofenadine (Allegra) and anti-inflammatories have not helped the swelling, it is very important to have a healthcare professional examine your mouth. They can safely check for infection or severe burns without judgment. If you experience any difficulty breathing or swallowing, please seek emergency medical care immediately.

The burning red bumps and itching you describe sound like hives (urticaria). Since they improve with antihistamines, it suggests an allergic-type reaction. Interestingly, certain acid reflux medications, such as proton pump inhibitors (like omeprazole) or H2 blockers (like famotidine), can occasionally trigger delayed drug-induced skin reactions. This explains why the flare-ups happen a few days after taking them. I gently recommend discussing this with your doctor. They can help identify the exact trigger and safely transition you to an alternative reflux management plan.
