Medical Therapy

Dietary Changes

  • Alcohol has been shown to drastically exacerbate all types of orthostatic intolerance due to its vasodilation and dehydration properties. It should be avoided whenever possible because of its adverse effects and its interactivity with many of the medications prescribed to POTS patients.
  • Caffeine helps some POTS patients due to its stimulative effects, however, other patients report a worsening of symptoms with caffeine intake. Each patient should experiment to determine whether caffeine helps or hurts his or her condition.
  • Diets high in carbohydrates have been connected to impaired vasoconstrictive action. Eating foods with lower carbohydrate levels can mildly improve POTS symptoms.
  • Eating frequent, small meals can reduce gastrointestinal symptoms associated with POTS by requiring the diversion of less blood to the abdomen.
  • Patients diagnosed with POTS will usually be advised to maintain a high sodium diet in order to augment the effects of their medication regimen, especially if that regimen includes fludrocortisone. Patients should also drink plenty of fluids, with a recommended intake of at least two liters per day and as much as 500 milliliters every two hours throughout the day.

Physical Therapy

POTS symptoms can be worsened by postural asymmetries, restrictions in mobility, and areas of adverse mechanical tension in the nervous system. These physical abnormalities can be relieved with gentle manual therapies including neural mobilization (or neural tension work), myofascial release, and cranio-sacral therapy.

External Body Pressure

Pressure garments can reduce symptoms associated with orthostatic intolerance by constricting blood pressures with external body pressure. Compression hose and anti-embolism stockings, both knee and thigh-high, provide relief for many patients. For especially severe cases, military anti-shock trousers and anti-gravity suits, or g-suits can be helpful but also limiting.


Exercise is very important for maintaining muscle strength and avoiding deconditioning. Though many POTS patients report difficulty exercising, some form of exercise is essential to controlling symptoms and eventually, improving the condition.


There is at this time only one drug approved by the FDA to treat orthostatic intolerance, however several classes of drugs often provide symptom control and relief. Treatments must be carefully tested due to medication sensitivity often associated with POTS patients, and each patient will respond to different therapies in different ways. Most patients will respond to some form of treatment.


The first line of treatment for POTS is usually fludrocortisone, or Florinef, a corticosteroid used to increase sodium retention and thus increase blood volume and blood pressure. An increase in sodium and water intake must coincide with fludrocortisone therapy for effective treatment. Dietary increases in sodium and sodium supplements are often used. Gatorade is also effective in providing both sodium and fluid.

Beta Blockers

Beta blockers such as atenolol and propanolol are often prescribed to treat POTS. These medications work by blocking the effects of epinephrine and norepinephrine released by the autonomic nervous system. Beta blockers also reduce sympathetic activity by blocking sympathetic impulses.


Midodrine (Proamatine), is approved by the U.S. FDA to treat orthostatic hypotension, a condition related to POTS. It is a stimulant that causes vasoconstriction and thereby increases blood pressure and allows more blood to return to the upper parts of the body. Use of midodrine is often discontinued due to intolerable side-effects, and it is known to cause supine hypertension (high blood pressure when lying down).


Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs) such as Prozac, Zoloft, Celexa, Lexapro, and Paxil, can be extremely effective in re-regulating the autonomic nervous system and raising blood pressure. Some studies indicate that serotonin-norepinephrine reuptake inhibitors (SNRIs) such as Effexor and Cymbalta are even more effective. Tricyclic antidepressants, tetracyclic antidepressants, and monoamine oxidase inhibitors are also occasionally, but rarely, prescribed. A combination of two antidepressants, usually an SSRI or SNRI with Wellbutrin or Remeron, is also shown to be very effective.


Medications used to treat ADD and ADHD such as Ritalin and Adderall are used to balance dopamine levels, increase vasoconstriction, and increase blood pressure.


Anti-anxiety medications, such as Xanax, Ativan, and Klonopin, can be used to combat imbalances of adrenaline usually seen with POTS patients.
