I am a 21-year-old girl. I get rashes on my hands and face due to allergy from certain foods. Since I live alone, it gets difficult for me to manage on my own whenever I get these allergy attacks. In fact, this thing has increased for the past two and a half years. I avoid eating brinjals and prawns altogether, but even then I keep on waking up with rashes on some days. I take Cetirizine on a daily basis, but I need to know whether this is okay for my health or not. Also, will I get the rashes the moment I stop taking the medicine? Please help me out with your advice.
