Since the redness, itching, and new swelling on your forehead have lasted a week and are not improving with cetirizine (Cetricip) or fexofenadine (Allegra), it is very important that you see a healthcare provider or dermatologist promptly. Even ammonia-free hair dyes can contain other sensitizing ingredients. The swelling suggests a stronger inflammatory response that typically requires a prescription treatment, like a topical or oral corticosteroid, which over-the-counter antihistamines cannot fully resolve. Please avoid scratching and do not apply any more hair products. A doctor can safely guide your recovery.

Yes, Allegra (fexofenadine) is generally very safe and effective for daily, long-term use to manage sneezing and allergy symptoms. As a non-drowsy antihistamine, it is well-tolerated by most people. However, it is always a good idea for her to consult her doctor or pharmacist to confirm it is safe alongside any other medications she might be taking or any health conditions she may have.

Her oxygen levels of 92-94% are borderline and require close monitoring. It is generally safe to continue Allegra M (fexofenadine and montelukast) and Reswas syrup (cloperastine) to help manage her cough. However, Defcort (deflazacort) is a steroid. While steroids are helpful in certain stages of COVID-19, they must be timed carefully. Because her oxygen is borderline, please consult her prescribing doctor immediately before administering Defcort. Monitor her oxygen levels every few hours, and seek urgent emergency medical care if her oxygen drops below 92% or if she experiences difficulty breathing.

Since fexofenadine (Allegra) hasn't provided relief, these symptoms?particularly worsening at night with blistering?highly suggest a skin condition like scabies, which can sometimes be linked to pet exposure. I recommend seeing a doctor or dermatologist for a physical exam and a quick skin scraping to confirm. If confirmed, the standard treatment involves prescription topical permethrin cream or oral medication, as antihistamines won't cure the underlying cause. It is also important that all household members are treated simultaneously, and bedding is washed in hot water.

Cold and sweet foods can trigger a reflex that temporarily narrows your airways and increases mucus, especially if you have sensitive lungs. Regarding your previous medicines, Allegra M (fexofenadine and montelukast) helps control allergies and airway swelling, while Aerodil syrup (containing terbutaline and mucolytics) works to relax airways and thin mucus. While these medications target your symptoms, wheezing and tight breathing can escalate quickly. It is safest to avoid reusing old prescriptions without a doctor's evaluation, as you may need a different preventive treatment. Please consult a healthcare professional to ensure you get the safest, most effective care.

Since the cold, dry air from your AC or fan triggers these symptoms, it likely points to nasal dryness and airway sensitivity rather than a bacterial infection. This explains why Azithromycin 500, Flozen AA, and Allegra M haven't provided relief. I recommend stopping the antibiotic unless specifically prescribed by your doctor. Instead, try using a generic saline nasal spray to restore moisture to your nasal passages and a generic cough suppressant like dextromethorphan for the dry cough. Using a room humidifier and avoiding direct airflow will also provide immense comfort.
