Zyrtec
urticaria
"Hives is directly linked to autoimmune disorders such as Hashimoto's-  a thyroid disease. Chronic hives can't be treated with Zyrtec if this is the case. I give Zyrtec 8 stars BC it is a great otc fix for allergies. However if you are suffering from chronic hives and find nothing helping, perhaps you need to research ... I am experiencing this first hand. I have found oatmeal baths and coconut oil with essential oils to sooth my chronic hives- specifically lavender, lemon, Meleluca,  and peppermint. My next step is getting a full blood panel done to confirm Hashimoto's. ...Zyrtec can't fix that but is good for common allergies."
