I have eczema on my face though it usually only flares up in

Hello from JustAnswer. Eczema can have a variety of triggers, but when the symptoms are worse when awakening, the most common reason is an allergy/sensitivity to something to which you are exposed during the night. For example, many people are sensitive to dust mites, and dust mites permeate bed linens, pillows, and mattresses, so that there is significant exposure during the night. You have already tried allergy tablets, which usually contain an antihistamine, and that is a reasonable approach. There are also many different antihistamines on the market, and different ones work better for different people, so it is reasonable to try different antihistamines to find which works best for you. Emollients and hydrating creams are also common interventions for eczema, and you do not say which creams you have tried, but it would be reasonable to try creams that contain lactic acid or alpha hydroxy acids. If symptoms do not respond to home interventions, then it may be necessary to use a short course of oral steroids, but these are only available by prescription, so it would be necessary to be seen by your doctor. If I can provide any additional information, please let me know.

Which allergy tablets have you tried?

There are a couple of options that you can try. It looks like the antihistamine in the Tesco own hayfever tablets is loratidine. Since you have tried loratidine and cetirizine, it would be reasonable to try a different antihistamine, such as Benadryl/diphenhydramine, and it may work better to take the medicine each night as you go to sleep to try to prevent the reaction during the night. It also would be reasonable to try a lactic acid cream, such as Amlactin Moisturizing Lotion.
