Treatments Your Physician May Prescribe
  • Oral medications, including nifedipine (a blood pressure medication), epoprostenol (a prostaglandin), or a drug that affects the nerves (selective serotonin reuptake inhibitor), such as fluoxetine. 
  • Topical nitroglycerin paste, which helps to dilate blood vessels, may be used as needed to treat or prevent active Raynaud's disease. Apply the paste carefully as it can lead to low blood pressure (hypotension) if used on large areas.
  • Biofeedback, which is a treatment technique in which people are trained to improve their health by using signals from their own bodies, is another therapy for Raynaud's disease.
