I am on Levathyroxine, and have now had a second 3 day spell of very high blood pressure, palpitations, irritability and shortness of breath. Previously I ended up visiting the emergency dept. at hospital, who said my dose had been increased too rapidly. It stabilised, and I increased the dose (over 3 months) gradually to 0.50mg, then latterly to 0.75mg. After having the same (albeit not as severe) symptoms I reduced back down to 0.50mg, then later this week I continued to feel unwell, so this weekend Ive reduced to 0.25mg. After 2 days of high blood pressure (155/109), I feel ok now. But Im worried about the damage this is doing to my heart/increased risk of stroke? Been to various doctors and they are not listening?
I can understand your worries. As your blood pressure was high only for few days, it is less likely to having significant damage to your heart or brain. Your high blood pressure is likely due to inappropriate thyroxine dose. So consult your family physician or endocrinologist. They will range TSH /T3/T4 for you. According to results they will decide appropriate thyroxine dose for you. When you're taking that appropriate thyroxine dose your blood pressure will come down to normal values.
