Droxidopa: Treatment for Neurogenic Orthostatic Hypotension
Introduction: Key Points About Droxidopa
Droxidopa is a prescription medication primarily used to manage symptoms of low blood pressure upon standing, a condition known as neurogenic orthostatic hypotension (nOH). This medication works to improve blood flow, helping to alleviate dizziness and lightheadedness. It is often prescribed for individuals with neurological disorders such as Parkinson’s disease or multiple system atrophy. In the United States, Droxidopa is marketed under the brand name Northera.
Understanding Droxidopa and Its Drug Class
Northera (Droxidopa)
“Droxidopa” is the generic name of this medication, while “Northera” is its brand name. Both refer to the same active ingredient, which is specifically designed to manage the symptoms of neurogenic orthostatic hypotension effectively.
How Droxidopa Works: Mechanism of Action
Droxidopa functions by converting into norepinephrine, a vital chemical that helps regulate blood pressure. Norepinephrine works by causing blood vessels to constrict, which raises blood pressure and enhances blood flow to the brain and other parts of the body. This process helps relieve symptoms such as dizziness, lightheadedness, and fainting that occur when standing. Unlike some other treatments for orthostatic hypotension, Droxidopa directly addresses the underlying norepinephrine deficiency, making it particularly effective for individuals with neurological conditions that impair norepinephrine production.
Benefits of Droxidopa Treatment
Droxidopa is specifically formulated to treat neurogenic orthostatic hypotension (nOH), a condition that can significantly disrupt daily life by causing dizziness, fainting, and fatigue. It is especially beneficial for individuals with underlying neurological disorders such as Parkinson’s disease, multiple system atrophy, or pure autonomic failure. Droxidopa is often preferred because it targets the root cause of nOH—low norepinephrine levels—rather than merely addressing the symptoms. Many patients report an improved quality of life and a greater ability to carry out daily activities while taking this medication.

Potential Side Effects of Droxidopa
As with any medication, Droxidopa may cause side effects. While many patients tolerate it well, it is important to be aware of possible reactions and to discuss any concerns with your healthcare provider. Below is a list of potential side effects, categorized by frequency. If you experience severe or persistent symptoms, contact your doctor immediately. Our telemedicine providers are here to address any concerns promptly.
Common Side Effects (≥1%)
- Headache (13%): Headaches are the most frequently reported side effect. Staying hydrated and managing stress may help reduce this symptom.
- Dizziness (11%): Dizziness, particularly when standing quickly, is common due to the medication’s effect on blood pressure. Patients with a history of orthostatic hypotension may be more prone to this side effect.
- Nausea (8%): Some patients report mild to moderate nausea, which may improve over time or with food intake.
- Hypertension (7%): Elevated blood pressure can occur, especially in patients with pre-existing hypertension or those taking other medications that raise blood pressure. Regular monitoring is recommended.
- Fatigue (5%): Unusual tiredness is another reported side effect, which often subsides as the body adjusts to the medication.
- Urinary Tract Infection (4%): A slight increase in the risk of urinary tract infections has been observed in some patients.
- Falls (3%): Falls may occur due to dizziness or changes in blood pressure. Patients with mobility or balance issues should take extra precautions.
Less Common Side Effects (<1%)
Less common side effects include dry mouth, abdominal pain, insomnia, anxiety, palpitations, blurred vision, and rash. Although rare, these should still be reported to your healthcare provider if they occur.
Severe Side Effects
Severe side effects, though rare, may include significant increases in blood pressure (hypertensive crisis) or allergic reactions such as swelling, difficulty breathing, or severe rash. These require immediate medical attention. If you experience any of these symptoms, stop taking Droxidopa and contact your doctor or seek emergency care right away.
It is essential to consult a healthcare provider before starting Droxidopa, particularly if you have underlying health conditions or are taking other medications. Our telemedicine team is here to guide you through the process and ensure your treatment is both safe and effective.
Drug-to-Drug Interactions with Droxidopa
Droxidopa, a medication frequently prescribed for neurogenic orthostatic hypotension (NOH), can interact with other drugs, potentially affecting its efficacy or increasing the likelihood of side effects. Being aware of these interactions is crucial for ensuring safe and effective treatment. Below are some of the key drug-to-drug interactions associated with droxidopa:
Monoamine Oxidase Inhibitors (MAOIs): Combining droxidopa with MAOIs (e.g., phenelzine, tranylcypromine) can cause a significant rise in blood pressure, increasing the risk of a hypertensive crisis. This combination should be avoided unless explicitly recommended and closely monitored by a healthcare provider.
Sympathomimetic Agents: Over-the-counter decongestants containing pseudoephedrine or phenylephrine may amplify droxidopa’s blood pressure-raising effects. It is important to consult your doctor before using these medications to avoid potential complications.
Beta Blockers: Medications such as propranolol may counteract droxidopa’s ability to regulate blood pressure and heart rate, potentially reducing its therapeutic benefits. Your healthcare provider may need to adjust the dosage or explore alternative treatment options in such cases.
Dopamine Antagonists: Drugs like metoclopramide may interfere with droxidopa’s mechanism of action, potentially diminishing its effectiveness in managing symptoms of neurogenic orthostatic hypotension.
Other Antihypertensives: When droxidopa is combined with medications that lower blood pressure, careful monitoring is essential to prevent excessive fluctuations in blood pressure. Regular follow-ups with your healthcare provider are critical to ensure safe and effective treatment.
To reduce the risk of harmful interactions, always provide your healthcare provider with a complete list of all medications, supplements, and over-the-counter products you are taking. This proactive approach helps ensure the best possible outcomes for your droxidopa treatment.
