Droxidopa (brand name Northera) is an FDA-approved medication for neurogenic orthostatic hypotension (nOH) — a condition where blood pressure drops significantly when standing, causing dizziness, lightheadedness, or fainting. It is associated with Parkinson's disease, multiple system atrophy, and pure autonomic failure. Droxidopa was approved by the FDA in February 2014 and is manufactured by Lundbeck.
Droxidopa is a norepinephrine precursor — a synthetic amino acid that your body converts into norepinephrine using the enzyme DOPA decarboxylase. Norepinephrine causes blood vessels to constrict, raising blood pressure. In patients with nOH, nerve damage reduces natural norepinephrine production, and Droxidopa supplements this deficit.
Taken three times daily (morning, midday, late afternoon). Starting dose is 100mg TID, titrated up in 100mg increments every 24-48 hours to a maximum of 600mg TID.
Droxidopa scores 30 out of 100 on the Medfinder findability scale, making it one of the harder medications to locate. As a specialty drug for neurogenic orthostatic hypotension, it's not stocked at most retail pharmacies. Brand Northera is distributed primarily through specialty pharmacies, though generic Droxidopa has improved availability somewhat. Prior authorization requirements and high cost create additional access barriers.

Droxidopa is most commonly prescribed by neurologists, particularly those specializing in movement disorders or autonomic dysfunction. Cardiologists who treat syncope and autonomic specialists at academic medical centers may also prescribe it. Some primary care physicians will manage refills once a specialist initiates therapy.
No. Droxidopa is not classified as a controlled substance by the DEA. However, it is a prescription-only medication that typically requires prior authorization from insurance companies before coverage is approved.
Boxed Warning: Supine hypertension (high blood pressure when lying down). Patients should elevate the head of the bed and take the last dose at least 3 hours before bedtime.
Droxidopa is a uniquely targeted medication for patients with neurogenic orthostatic hypotension. While finding it can be challenging due to specialty distribution and prior authorization requirements, generic availability has dramatically reduced costs.
