While a hot bath feels temporarily soothing, hot water actually dries out your skin and can worsen itching. Please switch to lukewarm baths and apply a thick, fragrance-free moisturizer immediately afterward. Since pheniramine (Avil) and calamine are not providing relief, please consult a doctor to identify the underlying cause. You may need a different class of antihistamine or a prescription topical treatment. Avoid scratching to prevent infection, and seek immediate medical attention if you experience any swelling, hives, or difficulty breathing.

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.

The rashes you describe, which respond to Avil (pheniramine), are likely hives (urticaria). The hot and cold flashes could indeed be linked, as histamine release can affect your body's temperature regulation, or they might point to an underlying systemic cause. While there isn't always a quick 'permanent cure,' these symptoms are highly manageable. I gently encourage you to see an allergist or dermatologist. They can help identify specific triggers, run basic blood tests, and create a safe, long-term treatment plan to bring you lasting relief.

Since Avil, Tetmosol soap, and the lotion have not provided relief, I highly recommend consulting a dermatologist. The itching could be due to resistant scabies, an allergic reaction, or post-treatment skin sensitivity. In the meantime, try using a gentle, fragrance-free moisturizer to soothe your skin, and avoid hot showers, which can worsen itching. A doctor can safely prescribe targeted treatments, like stronger generic antihistamines or topical creams, to help you find relief and heal.

While mild headaches can occasionally occur with pheniramine (the active ingredient in your allergy medication), a severe headache followed by vomiting is not a typical side effect and could point to another cause, such as a migraine. To help relieve the current mild headache, you may take a standard dose of paracetamol or ibuprofen, provided you have no allergies to them. I recommend reducing your pheniramine intake, as three tablets daily is a high dose that can cause significant drowsiness. Please consult a doctor to properly evaluate this headache and explore safer, non-drowsy allergy alternatives.

Avil 25 (pheniramine) is an antihistamine, not a steroid. It is commonly used to treat allergies. Regarding your concern about your eyes, high doses of antihistamines can sometimes cause temporary vision changes, like mild blurring or dry eyes, due to their drying effects. While it is very rare for pheniramine to cause glaucoma in a young, healthy individual, high doses can increase pressure in the eyes of those who are already prone to a specific type called angle-closure glaucoma. I highly recommend discussing your dosage with a doctor to ensure you are using it safely.
