Northera Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Northera (droxidopa) is a synthetic amino acid precursor of norepinephrine used for the treatment of orthostatic dizziness, lightheadedness, or the "feeling that you are about to black out" in adult patients with symptomatic orthostatic hypotension (NOH) caused by primary autonomic failure [Parkinson's disease (PD), multiple system atrophy and pure autonomic failure], dopamine beta-hydroxylase deficiency, and non-diabetic autonomic neuropathy. Common side effects include headache, dizziness, nausea, and hypertension.
The recommended starting dose of Northera is 100 mg, taken orally three times daily: upon arising in the morning, at midday, and in the late afternoon at least 3 hours prior to bedtime (to reduce the potential for hypertension during sleep). Northera may interact with other drugs that increase blood pressure (e.g., norepinephrine, ephedrine, midodrine, and triptans), or Parkinson's medications. Tell your doctor all medications and supplements you use. During pregnancy, Northera should be used only if prescribed. This drug may pass into breast milk and could have undesirable effects on a nursing infant. Breastfeeding is not recommended while using Northera.

Northera FDA Prescribing Information: Side Effects
The following adverse reactions with NORTHERA are included in more detail in the WARNINGS AND PRECAUTIONS section of the label:
- Supine Hypertension [see WARNINGS AND PRECAUTIONS]
- Hyperpyrexia and Confusion [see WARNINGS AND PRECAUTIONS]
- May exacerbate existing ischemic heart disease, arrhythmias, and congestive heart failure [see WARNINGS AND PRECAUTIONS]
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety evaluation of NORTHERA is based on two placebo-controlled studies 1-2 weeks in duration (studies 301 and 302), one 8-week placebo-controlled study (study 306) and two long-term open label extension studies (studies 303 and 304). In the placebo-controlled studies, a total of 485 patients with Parkinson's disease, multiple system atrophy, pure autonomic failure, dopamine beta-hydroxylase deficiency, or non-diabetic autonomic neuropathy were randomized and treated, 245 with NORTHERA and 240 with placebo [see Clinical Trials].
The most commonly observed adverse reactions (those occurring at an incidence of greater than 5% in the NORTHERA group and with at least a 3% greater incidence in the NORTHERA group than in the placebo group ) in NORTHERA-treated patients during the three placebo-controlled trials were headache, dizziness, nausea, hypertension. The most common adverse reactions leading to discontinuation from NORTHERA were hypertension or increased blood pressure and nausea.

Long-Term, Open-Label Tr ials with NORTHERA
In the long-term open label extension studies, a total of 422 patients, mean age 65 years, were treated with NORTHERA for a mean total exposure of approximately one year. The commonly reported adverse events were falls (24%), urinary tract infections (15%), headache (13%), syncope (13%), and dizziness (10%).
