l have been on levothyoxine for underactive thyroid for many years now, slowly increasing in dose. However, a year ago l went from 50mg to 75mg
and suffered a bout of vertigo
and dizziness. 6 months ago, l was then increased to 100mg and once again suffered extreme vertigo, raised BP and dizziness. Beta blockers have now reduced my BP to normal. Problem is l am extremely disoriented, stumble around, blurred vision, suffer anxiety attacks to mention just a few symptoms. ls my dose too high?
