Levothyroxin Side Effects

I have been on Levothyroxin for 6 weeks, I have an underactive Thyroid. I have been taking the medication about 4-5am and go back to bed. I'm up at 7am and by 9am I'm so dizzy( weird dizzy feeling/hard to explain, can't focus, so tired, blurred vision). I have to lay down and sleep. By 4-5pm the dizziness is better(NOT gone completely) and I feel like I'm flushed, like i'm coming off a bad flu.....then it starts ALL over again the next day. I decided to try to take it at night about hour after eating(about 7pm) ...so dizzy in the night and by 7am still dizzy. By about 12-1pm I start feeling a little better. Wondering if this is all side effects? or is my dose TOO low(only on 23mg). SO Frustrating...see Neurologist and Dr. this week

That is very unusual and not typical of the side effects of this medication.

I mean, these can all be side effects to a certain degree, but they aren't usually so severe.

Have you contacted your doctor? It really seems your dosing may not be right and it may need to be adjusted.

Yes I agree, I think I have to be adjusted and also saw Neurologist today and is sending me to ENT as may be something else going on, I suffer from migraines and daily chronic headaches as well but this dizziness is just weird and awful weird dizzy(not like vertigo) feeling. I think regulated my thyroid will help. Thanks for your reply
