I am currently on estradot, I've been trying different patches but unfortunately was allergic to them all, finally found estradot and was totally fine, I've been on it 2 months, I renewed my prescription and chemist gave me estramon and said they're the same after saying I can only use estradot. Put on Sunday night, small itching this morning and took antihistamines but as the evening is going on I'm getting burning itching on joints, face, lips I really need to take this off ? But the chemist isn't open until 9am can I go that long without a patch?
