Side effects and cautions

Vasodilators are strong medications and are generally used only as a last resort, when other medications haven't adequately controlled your blood pressure.

These medications have a number of side effects, some of which require taking other medications to counter those effects.

Side effects include:

  • Chest pain
  • Rapid heartbeat (tachycardia)
  • Heart palpitations
  • Fluid retention (edema)
  • Nausea
  • Vomiting
  • Dizziness
  • Flushing
  • Headache
  • Nasal congestion
  • Excessive hair growth

In addition, some vasodilators can increase your risk of developing lupus, a connective tissue disease.
