I would first like to find out if there is an inciting trigger, whether it be nuts, seafood, dust, etc. Based on the patients history, it seems that the urticaria was re triggered. Tab Atarax dose was also very low for the patients body weight.
Next Steps
Increase the dosing of Atarax to 25mg 3x/day. Some individuals may get drowsy with this type of antihistamine, if so in place take Tab. Allegra 180mg in the morning and afternoon. I would highly recommend to get a Serum IgE level done. De-worming yourself was a good idea, but as the lesions returned i feel this is the best option. Topically, nothing was given to you, so please use any brand of calamine lotion with liquid paraffin and aloe vera.
Health Tips
Look out for new lesions. If you are feeling too drowsy, then please dont take atarax during the day time.
