Question: do hayfever tablets help eczema?
Answer: How do antihistamines help with severe eczema? Antihistamines won't stop a flare-up, but they may be able to relieve itching. Diphenhydramine (Benadryl), which you can buy at the store, is a good choice. Your doctor can also prescribe hydroxyzine (Atarax) and cyproheptadine.
