Norfloxacin is typically cleared from your body within 24 hours. However, the allergic immune response it triggered can sometimes persist for several days or even a couple of weeks, which is why you are still seeing hives. Your use of Avil (pheniramine) and levocetirizine is excellent for managing these symptoms, but it can take some time for the skin to fully calm down. Please continue to monitor your symptoms. If you experience any swelling of your lips or face, or have difficulty breathing, please seek medical attention immediately.

Because pheniramine (Avil) did not bring relief, this rash is likely not an allergic reaction. A painful, burning rash preceded by skin sensitivity on the neck and chest is highly suggestive of shingles (herpes zoster), which is a viral reactivation. It could also be a localized skin irritation. I highly recommend having a doctor evaluate this promptly. If it is shingles, starting generic prescription antivirals like acyclovir or valacyclovir early can greatly speed up your healing and relieve the pain. In the meantime, cool compresses may help soothe the area.

Yes, Avil 25 Tablet can be taken for rashes that appear after eating street food, as it is an antihistamine that helps reduce allergic reactions such as itching, redness, and skin rashes; however, it may cause drowsiness, so caution is needed if you have to drive or work, and if the reaction is severe with swelling of lips or tongue, difficulty in breathing, or dizziness, you should seek emergency medical care instead of relying only on Avil.

These symptoms?especially the skin spots, stomach pain, and vision changes?suggest a systemic issue like urticarial vasculitis or a severe allergic reaction. Because these symptoms affect multiple parts of your body and returned after antihistamines, it is very important that you seek emergency medical care immediately. Please go to the nearest emergency room. Doctors there can safely manage this, potentially using medications like epinephrine or corticosteroids to reduce the inflammation quickly.

Since the injections of Avil (pheniramine) and Deca (dexamethasone) have not fully resolved your reaction, I highly recommend consulting your doctor or visiting an urgent care clinic promptly for a re-evaluation. They can safely adjust your treatment. In the meantime, try applying cool compresses and wear loose clothing to soothe your skin. Please avoid scratching to prevent infection. Most importantly, if you develop any difficulty breathing, swelling of your face or throat, or dizziness, please seek emergency medical care immediately.

After a severe allergic reaction, your throat tissues and airways can remain highly sensitive and mildly inflamed, even after treatment with pheniramine (Avil) and cortisone injections has resolved the immediate danger. Because you are still experiencing mild breathing trouble, it is very important to have a healthcare professional evaluate your airways to ensure they are completely safe and open. Please seek prompt medical attention for a follow-up, and go to the nearest emergency room immediately if your breathing difficulty worsens.
