Propranolol, pyridostigmine, midodrine, fludrocortisone, ivabradine and others: how they work, the evidence behind each, side effects, and why none is FDA-approved for POTS.
Every medicine used for POTS is prescribed off-label. A check of FDA drug labels found that none of propranolol, midodrine, ivabradine, pyridostigmine, fludrocortisone, droxidopa or modafinil lists POTS as an indication. This page describes what trials found. It does not tell you what to take.

NO MEDICINE HAS FDA APPROVAL FOR POTS
Clinicians often match the drug to the pattern, as the grid shows. That matching comes from clinical practice and has not been tested head to head in large trials.
A 2025 systematic review of 21 randomized trials (750 patients) called for large trials before any drug can be called first line. A 2024 review found ivabradine and midodrine had the highest rates of symptom improvement and beta-blockers the largest drops in heart rate variability. Both carry real uncertainty.

WHAT TO WATCH FOR
Print the visit checklist, write down the symptom that bothers you most, and ask which option fits your blood pressure and history. Track the result with repeat stand tests.
This page informs and does not diagnose. Only a clinician who can examine you and see your whole history can interpret your numbers.
