Itching after typhoid treatment may occur due to the infection itself or to the medicines. You should consult her doctor before changing any medication, so they can review her treatment, check for side effects, and suggest ways to relieve itching safely.

Frequent nose and throat infections during weather changes may be due to an allergy or low immunity. Allegra helps control allergy symptoms but may not prevent infections completely. Avoid cold exposure, maintain good hygiene, and support your immunity with a healthy lifestyle. Consult a doctor to review your condition and confirm the most suitable treatment.

Since fexofenadine (Allegra) hasn't helped, the symptoms might be caused by uncontrolled allergic rhinitis, post-nasal drip, or potentially cough-variant asthma. A pediatrician or pediatric allergist can help pinpoint the exact cause. They might recommend generic options like a nasal steroid spray or saline rinses to calm the inflammation, or evaluate him for asthma. I highly recommend scheduling a doctor's visit to help him finally get some restful sleep.

Since her oxygen saturation is dipping to 92% and her D-dimer is elevated at 900, she requires prompt medical evaluation. High D-dimer levels indicate a risk of blood clotting, and her doctor may need to consider blood thinners or adjust her treatment, which currently includes favipiravir (Fabiflu) and fexofenadine (Allegra). Please monitor her oxygen levels closely; if they stay below 94% or she develops breathlessness, seek hospital care immediately. Keep her well-hydrated, monitor her blood sugar, and consult her physician right away to safely guide her recovery.

Red rashes and itching that appear after a fever and body pain may indicate an infection, an allergic reaction, or a viral illness. You should consult a doctor immediately for proper evaluation and treatment to prevent complications.

It is very common for children to have a lingering cough and mild sore throat after recovering from COVID-19. Since your son is already taking Allegra (fexofenadine) and Zincovit, please continue these as prescribed by his doctor. To help soothe his airway and ease the nighttime cough, keep him well-hydrated with warm fluids and use a cool-mist humidifier in his room. Elevating his head slightly while sleeping can also provide comfort. If his cough worsens, or if he develops a high fever or breathing difficulties, please consult his pediatrician promptly.
