Hey guys, I'm back again with another doubt about Lamictal. I tried to research about it but not helping. So anyway, I've been on Lamictal for 3 weeks, now I'm on 50mg, gonna up my dose to 75mg next week. No rash or any bad side effect so far.

For the past few days, I'm having a "mildly tolarable" soar throat with phlegm and a bit of coughing. It seems to be worse when I wake up, subsides throughout the day.
The problem is, I've read up the sign of Steven Johnson Syndrom stating that "If you have Stevens-Johnson syndrome, several days before the rash develops you may experience: Fever, Sore mouth and throat, Fatigue, Cough, Burning eyes."

I do not have fever(at least for now), eyes burn rarely, but I do feel fatigued due to feeling drowsy sometimes. So is this a cause for a concern? Am I having flu due to Lamictal or is this normal flu? I don't want to get to the ER(as advised by pdoc) whenever I'm in doubt about my symptom.

I'd also like to add that my family and I are susceptible to catching flu seldom. This time, my niece and nephews visited me when they were having flu. So it may have passed down from them. But the main problem is, How do we know Normal flu vs Lamictal flu(steven johnshon)? The side effect stated online is vague about telling us the difference so I thought I'd get some opinion on it beside my other questions.
