Treatment depends almost entirely on the presence of symptoms and the underlying cause(s) of low blood pressure. In some cases, a physician may prescribe medication either to raise the blood pressure or to prevent the heart from slowing down. Sometimes, an increase in salt intake may be prescribed as well as avoiding dehydration. For patients with postprandial hypotension, avoiding large meals and large amounts of carbohydrates may help regulate their blood pressure. Patients may also be advised to avoid alcohol and standing suddenly, especially after eating. 

Medications that raise blood pressure by increasing sodium retention and absorption may be prescribed. Individuals with orthostatic hypotension may be prescribed fludrocortison, a medication that increases blood volume and is typically well-tolerated by patients. Other drugs that may be prescribed include ephedrine, midodrine, nonsteroidal anti-inflammatory drugs (NSAIDs) and caffeine. Patients with neurally mediated hypotension may be prescribed beta blockers. In addition, compression leg stockings may be used to improve blood return to the heart.

Sometimes treatment is not necessary because the kidneys can naturally balance low blood pressure by retaining salt and water, thereby increasing blood volume to allow the heart to work more effectively.

However, this self-regulating system is not foolproof – increasing the retention of salt and water may ultimately end up worsening the condition. People are encouraged to speak to their physicians if they have had low blood pressure readings or related symptoms.
