Hi I took my second dose of oxcarbazepine earlier today and noticed a few hours later that along with a killer headache my face was much puffier that normal. I think it may be too much stress and sodium, but wanted to double check before paging my on call doctor. I noticed after looking up side effects for the drug that my throat was feeling funny and swollen. I think that third symptom might be psychological. I took a mild antihistamine and figure I should just wait for any more pronounced symptoms...like trouble swallowing, etc. Mind you I am bipolar and have anxiety disorder so I am no stranger to false perception.
