Is Florinef Approved for Low Blood Pressure?
Florinef (fludrocortisone) is a synthetic mineralocorticoid used to treat orthostatic hypotension, a form of low blood pressure where standing causes dizziness or fainting due to blood pressure drops. It works by helping the body retain sodium and water, increasing blood volume and pressure.[1]
How Does Florinef Raise Blood Pressure?
Fludrocortisone mimics aldosterone, promoting sodium reabsorption in the kidneys. This expands plasma volume, stiffens blood vessels slightly, and boosts supine and standing blood pressure. Doses typically start at 0.1 mg daily, titrated based on response.[1][2]
What Conditions Is It Prescribed For?
Primarily for:
- Orthostatic hypotension from autonomic failure (e.g., Parkinson's, multiple system atrophy).
- Adrenal insufficiency (Addison's disease), where low blood pressure is a symptom.
Not first-line for essential hypertension or simple low blood pressure without volume depletion.[1][3]
Who Should Avoid Florinef for Low Blood Pressure?
Contraindicated in heart failure, hypertension, or edema due to risks of fluid overload. Common side effects include high blood pressure, swelling, low potassium, and headaches. Monitoring electrolytes and blood pressure is required.[1][2]
Alternatives to Florinef for Low Blood Pressure
- Midodrine: Alpha-agonist that constricts blood vessels for orthostatic hypotension.
- Droxidopa: Increases norepinephrine for neurogenic orthostatic hypotension.
- Non-drug options: Compression stockings, increased salt/fluid intake, or fludrocortisone combined with these.
Choice depends on cause—e.g., midodrine for pure vasomotor issues vs. Florinef for hypovolemia.[3][4]
Does Insurance Cover Florinef for This Use?
Often covered for FDA-approved indications like orthostatic hypotension. Generic fludrocortisone costs $10-50/month without insurance. Check DrugPatentWatch.com for pricing and patent status—no active patents block generics.[5]
