Levothyroxine And Dizziness (Page 2)
(Newest replies first)

I've been taking Levothyroxine 25mg for almost four months, first three months was fine, now seem to be having dizzy spells alot. (every day) also feeling bloated. Has anyone experienced this after 3 months of taking them? Another thing a couple of months ago my period was 13 days late!! its always been irregular but not normally that late. We are trying for a baby so i'm wondering if it could be pregnancy symtoms also.

@jane,

I definitely agree with you that Levo can mess up your whole system if it's not given right.

With Levo, dosing must be carefully controlled to achieve TSH levels within the normal reference range. Long-term suppression of TSH values below normal values will frequently cause cardiac related side-effects.

Overdose can result in heart palpitations, abdominal pain, nausea, anxiousness, confusion, agitation, insomnia, weight loss, and increased appetite.

Other side effects can be viewed in the link below:

I hope this info helps!

Hi. I was diagnosed with hypothyroidism. I just wanted to reply because you aren't alone! I started at 75mcg, then 88, then 100. I experienced a dizzy spell followed by tremors in both hands and legs and was rushed to the ER. They thought I was having a stroke. Gave me an MRI/MRA, heart ultrasound, EKG and found everything to be normal. They did find my thyroid elevated so now i'm on 112mcg (after 3 months was on 100) . I have experienced dizziness everyday since getting out of the ER and did spend a night. It's going on 2.5 weeks now and they are sudden. I'm being referred to an Endo to see what's going on. Not sure if it has to do with thyroid or something else, but I can't imagine what else it could be since the ER did thousands of dollars worth of tests! I know that a hormonal imbalance causes dizziness but who knows..could be adrenal fatigue. Also, I was on Synthroid for about a month and for some reason got my period twice in a month, so back to Levo. I'm only late maybe 6 days, yet another month 3 days early. I personally feel Levo just messes up your whole system if it's not given right. Make sure every 3 months you get a blood test and see the doc so they follow how your body reacts to it. Best bet is to see a Endo. Today is the FIRST day I didn't experience any dizziness and all I did was lay down, tilt my head back all the way to let some blood rush to my head. Don't know if that helped or what's going on. Good luck! Dizziness is NOT fun on a daily basis.
