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.

Given that the severe itching is on your hands and worsens significantly at night, one strong possibility to consider is scabies, a very common and highly treatable skin condition. Other possibilities include dyshidrotic eczema or contact dermatitis. Because over-the-counter options haven't helped, I highly recommend seeing a healthcare provider for a proper diagnosis. If it is scabies, they can prescribe a generic permethrin cream. If it is eczema, a topical corticosteroid may be recommended.

It sounds like you are experiencing an allergic reaction, possibly triggered by something in the hotel food. While Avil (pheniramine) provides temporary relief, the allergen may still be affecting your system, or you might be encountering ongoing triggers. I gently recommend consulting a doctor or allergist who can help identify the exact cause through allergy testing and prescribe a safe, daily non-drowsy antihistamine. Please seek immediate medical care if you ever experience any difficulty breathing, swallowing, or swelling of your lips and throat.

Since these antihistamines haven't helped after two days, I highly recommend consulting a doctor or dermatologist for a professional evaluation. They can identify specific triggers and may suggest stronger treatments, such as a brief course of oral corticosteroids or prescription topical steroid creams to quickly calm the inflammation. In the meantime, cool compresses can provide some soothing relief. Please seek immediate emergency care if you experience any swelling of your face or difficulty breathing.

Avil 25 Tablet (Pheniramine maleate) is an antihistamine that helps relieve symptoms of the common cold, such as runny nose, sneezing, watery eyes, and itching, but it does not cure the cold itself. The dose of Avil 25 Tablet varies depending on age, medical condition, and doctor’s advice; adults are usually prescribed one tablet 2–3 times a day, while children require lower doses, and since it is a Schedule G medication, it should only be used under strict medical supervision and never without a doctor’s prescription.

It sounds like you are experiencing hives, medically known as urticaria. When you scratch, it releases more histamine, causing the rash to expand?a common reaction called dermatographism. The quick relief you get from antihistamines also points to this. Hives can certainly be triggered by food allergies, infections, or stress. However, a mineral deficiency is a very unlikely cause for this type of rapid, reactive rash. I suggest keeping a food diary to track potential triggers and speaking with a doctor or allergist for a personalized evaluation.
