While fexofenadine (Allegra) and hydroxyzine (Atarax) are excellent antihistamines, chronic hives can sometimes be stubborn and require a personalized approach. Since you recently married, if you are planning a pregnancy, it is very important to discuss this with your doctor, as hydroxyzine (Atarax) may not be safe during pregnancy. Please schedule an appointment with your doctor or an allergist. They can safely adjust your dosage, explore other treatments, and help find the root cause of your hives to finally bring you some relief.

Your doctor likely prescribed Allegra (fexofenadine) to help manage bothersome allergy symptoms, itching, or hives, which can sometimes be triggered or worsened by infections or hormonal shifts. Fexofenadine is a safe antihistamine that will not interfere with your infection or hormone treatments. I highly recommend reaching out to your doctor's office to confirm exactly which symptom they are targeting. You deserve to feel completely clear and comfortable with your treatment plan.

Your eosinophil count is mildly high, which usually happens due to allergies. Since you have sneezing and a runny nose and feel better with Allegra-M, this is likely allergic rhinitis. You can continue using Allegra-M when needed, and use a saline nasal spray to keep your nose clear. Avoiding dust, cold air, and strong smells also helps. If it does not improve, consult a doctor.

Since Allegra (fexofenadine) has not brought relief, the rash may not be allergic in nature. Rashes near the hairline are often caused by conditions like fungal irritation, seborrheic dermatitis, or clogged hair follicles, which antihistamines cannot cure. Additionally, 180 mg of Allegra is typically a once-daily dose. I gently suggest stopping the twice-daily dosing and consulting a healthcare provider or dermatologist. They can properly examine your scalp and prescribe a targeted treatment. For now, please keep the area clean and dry, and avoid using harsh hair products or scratching.

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.

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.
