Since fexofenadine (Allegra) isn't helping, you might try switching to a generic corticosteroid nasal spray like fluticasone propionate, which is highly effective for a stuffed nose, sneezing, and itchy eyes. For your severe sore throat, generic pain relievers like ibuprofen or acetaminophen can help ease the pain. Simple remedies like warm saltwater gargles and honey can also bring great comfort. If your sore throat worsens, is accompanied by a high fever, or doesn't improve in a few days, please see a healthcare professional to ensure it isn't an infection.

While Allegra 120 (fexofenadine) is designed to treat allergies, antihistamines can sometimes cause mild dryness in the throat, which can feel like an itchy or 'stuck' sensation. Alternatively, this could simply be a symptom of your underlying allergies or mild reflux. I suggest sipping some warm water to see if it helps soothe your throat. However, if you ever experience difficulty breathing, swelling, or worsening symptoms, please seek medical attention immediately. I recommend sharing this with your doctor to ensure you stay comfortable and safe.

Regarding his medications, both Ibugesic Plus and Ibugesic contain ibuprofen. Giving both, alongside Allegra and T-Minic, risks an accidental overdose of similar active ingredients. I highly recommend consulting his pediatrician to safely review this drug combination and get the correct dosages tailored for his weight. For now, keep him comfortable and well-hydrated to help his body naturally fight off the virus.

The tiny red spots you noticed that fade or disappear when pressed (called blanching) are generally reassuring, as they often point to a mild, temporary skin reaction rather than anything serious. While it is possible to have a mild reaction to Allegra-M (fexofenadine and montelukast), it is relatively uncommon. Please monitor the spots to see if they spread or if you develop other symptoms like itching, swelling, or difficulty breathing. If you feel unwell or if the spots persist, it's best to stop the medication and consult your doctor or pediatrician for a quick check.

Since your antihistamines, like cetirizine and Allegra, are no longer helping, you might try a mild over-the-counter hydrocortisone cream applied sparingly to the itchy areas twice daily. For moisturizing, switch from Aqua lotion to a thick, fragrance-free emollient cream to help restore your skin barrier. Avoid hot water, harsh soaps, and tight clothing to prevent further irritation. Keep cool and try not to scratch. If you experience any swelling of your face or difficulty breathing, please seek immediate medical care. Otherwise, please consult your doctor in three days for a tailored treatment plan.

These symptoms suggest a potential systemic allergic reaction, especially given his history of using cetirizine, Allegra, or Relent. Because sudden swelling can sometimes affect the airway or indicate a vascular issue, please go to the nearest emergency department immediately for a proper evaluation. Once he is safe and stable, scheduling outpatient allergy testing is an excellent next step to identify his specific triggers. Please prioritize getting him evaluated by a doctor right away.
