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.

Since your symptoms returned after Avil (pheniramine) wore off, despite using Cetaphil and coconut oil, this might be due to nocturnal pruritus. At night, naturally occurring changes in body temperature and skin moisture can worsen itching. It could also suggest a condition like chronic hives or a localized nerve sensitivity. Because the itching is worsening, it is best to see a doctor. They can safely evaluate you and suggest longer-acting solutions to help you sleep comfortably.

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.

Please reassure yourself that this is highly treatable. While Avil helps temporarily ease the itching and Nevlon soap keeps your skin hydrated, they cannot cure the underlying cause. A contagious rash spreading among household members often suggests a condition like scabies. I strongly recommend that you and all family members consult a doctor together. You will likely need a prescription medicated cream, such as permethrin, applied simultaneously by everyone. Additionally, washing all clothes and bedding in hot water is essential to stop the spread.

Some allergy pills, like oral antihistamines, can take a few days to reach full effectiveness. Also, while they are great for sneezing, they are often less helpful for a stuffy nose. You might find better relief by adding a generic steroid nasal spray, such as fluticasone, which directly reduces nasal swelling. Please give your body a few more days to respond. If your symptoms don't improve or if you feel worse, please reach out to a doctor for a personalized evaluation.

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.
