Medications That Can Cause Low Blood Pressure
Several medicines may cause low blood pressure, including some medications used to control high blood pressure.
Working with your doctor or other health care provider to change your medication or adjust your dosage can help control low blood pressure. You should never modify a dose or stop taking a medication without first consulting your health care provider.
Alpha and beta blockers, diuretics, erectile dysfunction drugs, Parkinsons disease drugs and some types of antidepressants can cause low blood pressure.
Medications that can cause low blood pressure include:
- Benicar a prescription blood pressure medication
- Cialis an erectile dysfunction drug risk is especially high when taken with nitroglycerin heart medication
- Cymbalta a serotonin and norepinephrine inhibitor antidepressant
- Hydrochlorothiazide a widely used generic diuretic
- Inderal, Innopran XL and other versions of propranolol beta blockers
- Lasix a diuretic
How Does Blood Pressure Work
During relaxation of the heart , the left ventricle of the heart fills with blood returning from the lungs. The left ventricle then contracts and pumps blood into the arteries . The blood pressure in the arteries during contraction of the ventricle is higher because blood is being actively ejected into the arteries. It is lower during relaxation of the ventricle when no blood is being ejected into the arteries. The pulse we feel when we place our fingers over an artery is caused by the contraction of the left ventricle and the ejection of blood.
Blood pressure is determined by two factors:
Generally, blood pressure tends to be higher if more blood is pumped into the arteries or if the arterioles are narrow and/or stiff. Narrow and/or stiff arterioles, by resisting the flow of blood, increase blood pressure. Arterioles may become narrower when the muscles surrounding them contract. Arterioles may become stiff and narrow when older patients develop atherosclerosis.
Blood pressure tends to be lower if less blood is being pumped into the arteries or if the arterioles are larger and more flexible and, therefore, have less resistance to the flow of blood.
The heart rate increases and the forcefulness of the heart’s contractions increase, pumping more blood through the heart.
Which Number Is More Important
Typically, more attention is given to systolic blood pressure as a major risk factor for cardiovascular disease for people over 50. In most people, systolic blood pressure rises steadily with age due to the increasing stiffness of large arteries, long-term buildup of plaque and an increased incidence of cardiac and vascular disease.
However, either an elevated systolic or an elevated diastolic blood pressure reading may be used to make a diagnosis of high blood pressure. According to recent studies, the risk of death from ischemic heart disease and stroke doubles with every 20 mm Hg systolic or 10 mm Hg diastolic increase among people from age 40 to 89.

How To Lower Blood Pressure In Minutes
Disclaimer: Results are not guaranteed*** and may vary from person to person***.
High blood pressure can hit at any time, and the results can be devastating. When an acute jump occurs, knowing how to lower blood pressure in minutes can be the difference between life and death.
This is especially true if youre one of the 75 million American adults suffering from hypertension , or one of the other 75 million with prehypertension. When a boost hits, its good to know how to make blood pressure go down quickly.
Your blood pressure rises and falls throughout the day, and this is completely normal. Stress, anxiety, exercise, and activity can all lead to increases, while relaxation, getting ready for bed, and sleep can all bring it back down.
But not all high blood pressure is safe, and the longer it stays at a high rate, the more health risks you assume. Risks include acute responses like sweating, fainting or shortness of breath, and more severe issues like heart disease and heart attack can arise. So when stress hits, knowing how to lower blood pressure quickly can be a great health benefit.
Things You Can Do To Manage Low Blood Pressure
If low blood pressure isnt causing any symptoms or interfering with your daily routineand depending on the underlying causeyour doctor may decide to just keep an eye on your readings and ask you to be on alert for any warning signs, Dr. Mehta says.
There are also a few things you can do on your own to prevent problems.
1. Switch to mocktailsor good old H20. Remember, alcohol is dehydrating and can lead to a drop in blood pressure. Water is the preferred thirst quencher, since it helps increase blood volume.
2. Order the spinach salad. Certain foods play a key role in keeping your blood pressure in a healthy range. Vitamins B12 and folate, for example, help your body produce enough red blood cells to prevent anemia.
Leafy greens, avocados, beans, and oranges can help you meet your folate quota, according to the Academy of Nutrition and Dietetics. Chicken, eggs, fish, milk, yogurt, and meat are good sources of vitamin B12.
3. Dont skip meals. In fact, consider divvying up your meals into four or five small ones spread throughout the day. This can help prevent your blood pressure from dropping sharply after you push away from the table.
4. Uncross your legs. This can be a tough habit to break, but sitting with your legs crossed can hamper your blood flow. Its also good to start taking your sweet time when changing positionssitting to standing, lying to sitting, and so on.

Salt Water As A Instant Remedy For Low Blood Pressure:
Salt water helps to treat low blood pressure because the sodium content in the salt water enhances the blood pressure level. Drink a glass of salt water and blood pressure level will increase quickly. However, taking excess salt should be avoided because it may turn out to be unhealthy. Enhance the salt consumption in your daily diet and this is a wonderful home remedy for treating low blood pressure.
When Should You Call Your Doctor About Low Blood Pressure
If you have recurring dizziness or fainting, or other symptoms of low blood pressure, you should visit your doctor. Sudden drops in blood pressure can be dangerous. It is important for your doctor to determine why your blood pressure is dropping and treat the cause.

Postural Or Orthostatic Hypotension
Postural or orthostatic hypotension occurs when your blood pressure falls after a sudden movement. For example, you may feel dizzy or faint after changing posture, such as sitting up from a lying position, or standing up from a sitting position. This may cause you to lose your balance and fall over. You may also feel light-headed, have blurred vision, or lose consciousness.
The symptoms of postural or orthostatic hypotension should only last a few minutes as your blood pressure adjusts to your new position. This type of low blood pressure tends to affect people more as they get older when it can lead to more frequent falls. Similar symptoms may also occur after exercise.
Low Blood Pressure Definition And Facts
- Low blood pressure, also called hypotension, is blood pressure low enough that the flow of blood to the organs of the body is inadequate and symptoms and/or signs of low blood flow develop.
- Low pressure alone, without symptoms or signs, usually is not unhealthy.
- The symptoms of low blood pressure include lightheadedness, dizziness, and fainting. These symptoms are most prominent when individuals go from the lying or sitting position to the standing position .
- Low blood pressure that causes an inadequate flow of blood to the body’s organs can cause strokes, heart attacks, and kidney failure. The most severe form is shock.
- Common causes of low blood pressure include a reduced volume of blood, heart disease, and medications.
- The cause of low blood pressure can be determined with blood tests, radiologic studies, and cardiac testing to look for heart failure and arrhythmias.
- Treatment of low blood pressure is determined by the cause of the low pressure.

Signs And Symptoms Of High Blood Pressure
High blood pressure may not have any symptoms and so hypertension has been labeled “the silent killer.” Longstanding high blood pressure can lead to multiple complications including heart attack, kidney disease, or stroke.
Some people experience symptoms with their high blood pressure. These symptoms include:
- The Feeling of pulsations in the neck or head
What Is Low Blood Pressure
Hypotension is the medical term for low blood pressure .
A blood pressure reading appears as two numbers. The first and higher of the two is a measure of systolic pressure, or the pressure in the arteries when the heart beats and fills them with blood. The second number measures diastolic pressure, or the pressure in the arteries when the heart rests between beats.
Optimal blood pressure is less than 120/80 . In healthy people, low blood pressure without any symptoms is not usually a concern and does not need to be treated. But low blood pressure can be a sign of an underlying problem — especially in the elderly — where it may cause inadequate blood flow to the heart, brain, and other vital organs.
Chronic low blood pressure with no symptoms is almost never serious. But health problems can occur when blood pressure drops suddenly and the brain is deprived of an adequate blood supply. This can lead to dizziness or lightheadedness. Sudden drops in blood pressure most commonly occur in someone who’s rising from a lying down or sitting position to standing. This kind of low blood pressure is known as postural hypotension or orthostatic hypotension. Another type of low blood pressure can occur when someone stands for a long period of time. This is called neurally mediated hypotension.

Symptoms And Causes Of Low Blood Pressure
Many different conditions and situations can cause low blood pressure, from standing up too fast to being pregnant. Sometimes, low blood pressure is linked to an underlying problem. Thats why its important to see your doctor right away if you experience the signs of low blood pressure.
Symptoms of low blood pressure can include:
Low blood pressure can be a sign of serious heart, endocrine or neurological conditions. If left untreated, the brain and other vital organs do not get the oxygen and nutrients they need. In extreme cases, this can cause shock, a life-threatening condition.
If you show signs of low blood pressure, your doctor will conduct an exam and may perform tests to determine whats causing the condition. Low blood pressure can occur with many other conditions.
Some causes of low blood pressure are:

What Are The Different Blood Pressure Categories
Blood pressure can be categorized into five different types, namely:
Normal: Blood pressure below 120/80 mm Hg is considered to be normal.
Elevated: When blood pressure readings consistently range from 120 to 129 systolic and less than 80 mm Hg diastolic, it is known as elevated blood pressure. People with elevated blood pressure are at risk of high blood pressure unless steps are taken to control it.
Hypertension stage I: In this condition, blood pressure readings consistently range from 130 to 139 systolic or 80 to 89 mm Hg diastolic. Doctors may prescribe blood pressure medications and some lifestyle changes to reduce the risk of heart diseases and stroke.
Hypertension stage II: In this condition, blood pressure readings consistently range from 140/90 mm Hg or higher. The doctors may prescribe a combination of both medications and lifestyle changes.
Hypertensive crisis: This is the most critical condition and requires emergency medical attention. In this condition, the blood pressure suddenly exceeds 180/120 mm Hg. Contact the physician immediately if the following symptoms are experienced:
- Difficulty speaking
Your Blood Pressure Numbers And What They Mean
Your blood pressure is recorded as two numbers:
- Systolic blood pressure indicates how much pressure your blood is exerting against your artery walls when the heart beats.
- Diastolic blood pressure indicates how much pressure your blood is exerting against your artery walls while the heart is resting between beats.

Medication Used To Treat Low Blood Pressure
In cases of more severe or recurrent symptoms of low blood pressure, doctors may prescribe drugs to stabilize the system. These may include:
Fludrocortisone: It is a steroid that is prescribed when the body is unable to produce enough by itself, and is often prescribed in conjunction with other steroids such as hydrocortisone. It reduces inflammation in the body and causes the body to retain more sodium. It may cause some water retention, but this is not a cause for concern since it is necessary to build blood pressure. To maintain the sodium-potassium balance, a doctor might recommend consumption of potassium-rich foods such as apricot, bananas, spinach and broccoli while on this prescription. Once the effects of low blood pressure are no longer witnessed, you may be asked to discontinue the steroid, while maintaining lifestyle and diet changes.
Midodrine: A counter to blood vessel dilation, midodrine is a what is called a vasopressor and constricts small blood vessels to increase blood pressure. It is usually prescribed in cases of postural hypotension and the dosage is gradually increased over time to prevent side effects.

What The Studies Found And What They Mean
In one of the observational studies, published Oct. 16, 2016, in the Journal of the American College of Cardiology, researchers analyzed the medical records of more than 11,000 adults collected over a period of three decades as part of the Atherosclerosis Risk in Communities Study. They found that people who had low diastolic blood pressure were twice as likely to have subtle evidence of heart damage compared with people whose diastolic blood pressure was 80 to 89 mm Hg. Low diastolic values were also linked with a higher risk of heart disease and death from any cause over 21 years.
For the second, published Oct. 29, 2016, in The Lancet, researchers analyzed data from CLARIFY, a registry of more than 22,600 people with heart disease from 45 countries. They determined that, compared with people who had systolic blood pressure of 120 to 139 mm Hg and diastolic pressure of 70 to 79, people with a systolic blood pressure of 140 mm Hg or higher were more likely to experience heart attacks or strokes, to be hospitalized with heart failure, or to die within a five-year period. But the same was true for heart attacks, heart failure, and death in people with low blood pressure .
What To Do When Your Blood Pressure Drops Too Low And How To Raise It
Falling down of blood pressure below the normal range is referred to as low blood pressure or hypotension. The normal blood pressure reading is 120/80mm Hg, and a person with low blood pressure shows a reading of 90/60mm Hg or low. Having a low blood pressure without any symptoms might not be much of a problem, but if the symptoms start showing up it means that the blood supply to the body is being affected. If this happens the doctor might diagnose the condition to get the cause.
It is important to know what to do if your blood pressure drops too low and how to raise it. But before that let us understand the causes of low blood pressure and understand why your blood pressure drops too low. Some of the conditions causing low blood pressure involve
- Chest pain or heart attack in a patient suffering from heart disease.
- Sitting and standing may lead to vertigo or dizziness in the patient with postural hypotension.
- Increase in urea and creatinine levels in the patient with kidney disease. This happens due to decreased blood supply to the kidney.
- Kidney failure, heart failure, lung failure, and brain failure.

Diastolic Blood Pressure: How Low Is Too Low
- May 17, 2015
Blood pressure consists of two numbers. Systolic pressure, the force exerted on blood vessels when the heart beats, is the upper number. Diastolic pressure, the force exerted when the heart is at rest, is on the bottom in more ways than one. Systolic pressure attracts the lions share of attention from physicians and patients, says UAB cardiologist Jason Guichard, M.D., Ph.D.
Physicians are busy people, and like it or not they often focus on a single number, Guichard said. Systolic blood pressure is the focus, and diastolic pressure is almost completely ignored. That is a mistake, he argues. The majority of your arteries feed your organs during systole. But your coronary arteries are different they are surrounding the aortic valve, so they get blood only when the aortic valve closes and that happens in diastole.
Diastolic pressure has been getting more attention lately, however, thanks in part to an influential paper in Hypertension, written in 2011 by Guichard and Ali Ahmed, M.D., then a professor of medicine in UABs Division of Gerontology, Geriatrics and Palliative Care and now the associate chief of staff for Health and Aging at the Veterans Affairs Medical Center in Washington, D.C.
