Allegra (fexofenadine) is a daily medication that typically wears off within 24 hours. Once the medicine leaves your system, the itching returns because the underlying cause of your reaction is still active. Since the itching is severe and keeps coming back, I highly recommend scheduling an appointment with your doctor or an allergist. They can help identify the root cause, safely adjust your daily dose of fexofenadine, or recommend other targeted treatments to give you lasting relief.

Since your symptoms haven't improved after five days of using fexofenadine (Allegra 180) and Calosoft-AF lotion, I recommend consulting a doctor for a physical examination. While these treatments are excellent for soothing mild irritation, your persistent rash?which could be hives or contact dermatitis?may require a different approach, such as a prescription-strength topical cream. Please avoid switching to new medications without medical guidance.

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.

I am so sorry you are dealing with these persistent, frustrating throat infections. Since strong antibiotics like moxifloxacin, amoxicillin-clavulanate, and linezolid haven't cleared this up, we should look beyond typical bacterial infections. I highly recommend seeing an Ear, Nose, and Throat (ENT) specialist. They can perform a detailed exam, possibly using a small camera to look closely at your throat, and take specialized cultures to check for fungal or resistant organisms. We should also investigate non-infectious causes like silent acid reflux, allergies, or immune system health. There are many effective management options, sometimes including tonsillectomy, and we will work to find you lasting relief.

While mild redness at the injection site is common after vaccines, a spreading rash across your body is not a typical reaction and should be evaluated by a doctor promptly. Using calamine lotion to soothe the skin and Allegra 120 (fexofenadine) to help reduce itching is generally safe and appropriate for temporary relief. However, because the rash is spreading, please consult a healthcare professional or visit an urgent care clinic to ensure you are safe. If you experience any difficulty breathing, swelling of your face or throat, or dizziness, please seek emergency medical care immediately.

Since Gamascab and Allegra (fexofenadine) haven't provided relief, it is possible you are experiencing 'post-scabetic itch,' which can frustratingly persist for several weeks even after successful treatment. Other possibilities include treatment resistance, re-exposure, or a different skin condition altogether, such as eczema or a fungal infection in the skin folds. I highly recommend consulting your doctor or a dermatologist.
