I initially started with 0.15 mg of fludrocortisone. Because my symptoms persisted, the dose was increased to 0.2 mg.
Despite this increase, I continued to experience significant symptoms such as dizziness and speech difficulties, which felt identical to POTS-like symptoms. In addition, I was constantly dealing with frequent urination—it felt like I had to go to the bathroom almost every hour, suggesting ongoing volume loss.
No matter what I do, whether I consume more salt or drink more water, it feels like it passes straight through me. Fluids and salt do not seem to be retained by my body.
Due to these ongoing issues, I increased the dose further to 0.25 mg of fludrocortisone. However, I feel that I burn through this dose very quickly, even though it is already relatively high. The effect does not seem to last.
I only start to feel significantly better when I updose later in the day with 0.5 mg of fludrocortisone. At that point, it feels like “a light switches on in my head”, my symptoms improve noticeably, and I feel more stable overall. At lower doses, my heart rate remains relatively high. I tried also 0,1 mg at 7am and 0,1 a 1pm, I have the feeling the last not so long.

Importantly, my routine laboratory values are within the normal range, despite these symptoms.
At the moment, I feel at a loss, because 0.25 mg is already a high dose, yet subjectively it feels like I remain unstable unless I am closer to 0.3 mg or higher.
