Medications which may be effective include: CNS stimulants fludrocortisone, midodrine, SSRIs such as paroxetine or sertraline, disopyramide, and, in health-care settings where a syncope is anticipated, atropine or epinephrine (adrenaline). For people with the cardioinhibitory form of vasovagal syncope, implantation of a permanent pacemaker may be beneficial or even curative.Types of long-term therapy for vasovagal syncope include
Preload agents
Vasoconstrictors
Anticholinergic agents
Negative cardiac inotropes
Central agents
Mechanical device
Discontinuation of medications known to lower blood pressure may be helpful, but stopping antihypertensive drugs can also be dangerous in some people. Taking antihypertensive drugs may worsen the syncope, as the hypertension may have been the bodys way to compensate for the low blood pressure. Prognosis
Brief periods of unconsciousness usually cause no lasting harm to health. Reflex syncope can occur in otherwise healthy individuals, and has many possible causes, often trivial ones such as prolonged standing with the legs locked.The main danger of vasovagal syncope (or dizzy spells from vertigo) is the risk of injury by falling while unconscious. Medication therapy could possibly prevent future vasovagal responses; however, for some individuals medication is ineffective and they will continue to have fainting episodes. See also
