Hi,
I have found that I'm sensitive to a change of brand and Aristo is now the only brand of levothyroixine at my local pharmacy. Since changing from Accord 2 1/2 months ago I've found that I've been having repeated headaches and weight gain. Also my blood pressure is scarily high. I'm aware this can be a symptom of an underactive thyroid. I've been monitoring my BP for nearly a week now and although I'm taking 2.5mg of Ramipril there isn't really any considerable change. I've been feeling quite unwell this week, sleepy during the day and struggling to swim my usual 50 lengths in 20m pool. I'm not sure whether this is related to an underlying virus or change in levo brand. If any one has any similar experiences I'd love to hear from you.
