π₯Fludrocortisone will increase β¬οΈ RAAS and can cause volume overload, so you should avoid it here
π₯ Caffeine and ibuprofen are last-line agents to manage orthostatic hypotension
π₯ Midodrine is probably your best bet here

3/8 You prescribe midodrine 2.5 mg PO q8h and end up titrating it up to 5 mg PO q8h over the course of a few weeks. The patient shows you their BP log and you notice that their nighttime supine BPs are elevated. What do you do next?
4/8 It is reasonable to change the timing of the nighttime dose! To avoid nighttime supine hypertension with midodrine use, administer it 3-4 hours before the patient goes to bed.
5/8
π₯ Supine hypertension can increase this patient's afterload and worsen heart failure.
π₯ There are even case reports of caudate hemorrhage being implicated in this type of hypertension. mayoclinicproceedings.org

6/8 The patient shows up a month later and continues to have nighttime supine hypertension. You decide to stop the midodrine. What might you consider giving?
7/8 Consider pyridostigmine! AChEIs are better at preventing supine hypertension because post-ganglionic sympathetic nerves are thought to be activated during orthostatic stress and NOT when supine.
π§ I would ask my neurologist colleagues if this is reasonable.
