Medication for Blood Pressure

Medication for Blood Pressure

Medication for blood pressure are used to treat high blood pressure (hypertension) because they help lower blood pressure and reduce the risk of serious health problems like heart attacks, strokes, and kidney disease. The specific medication(s) prescribed will depend on factors like age, race, and other medical conditions. It’s important to take blood pressure medications as directed and to discuss any side effects with your healthcare provider.

Medications for hypertension

There are several major classes of medications used to treat high blood pressure (hypertension):

  • Diuretics: By assisting the body in eliminating extra salt and water, these “water pills” lower blood pressure.
  • Common diuretics include furosemide (Lasix), hydrochlorothiazide (HCTZ), and chlorthalidone.
  • ACE inhibitors: These relax blood vessels by blocking the angiotensin-converting enzyme, such as lisinopril (Prinivil, Zestril) and enalapril (Vasotec).
  • Angiotensin II receptor blockers (ARBs): Similar to ACE inhibitors, ARBs like valsartan (Diovan) and candesartan block the effects of angiotensin II to relax blood vessels.
  • Calcium channel blockers: These medications, such as amlodipine (Norvasc) and nifedipine, work by preventing calcium from entering the muscle cells of the heart and blood vessels, causing them to relax.
  • Beta-blockers: Metoprolol and atenolol are two examples of medications that lower blood pressure by lowering heart rate and heart workload.

The choice of medication depends on factors like the patient’s age, ethnicity, and other medical conditions. Many patients require a combination of two or more blood pressure medications to achieve their target levels.

Medications for hypotension

There are several medications used to treat hypotension (low blood pressure):


  • Promotes sodium retention by the kidneys, causing fluid retention and improved blood pressure
  • However, sodium retention also causes potassium loss, so potassium supplementation is needed


  • Stimulates receptors on tiny arteries and veins to raise blood pressure
  • Used to increase standing blood pressure in people with postural hypotension due to nervous system problems
  • An FDA-approved drug for treating orthostatic hypotension that functions as an α-1 agonist

Droxidopa (Northera)

  • An expensive drug used to reduce dizziness, lightheadedness, or feeling like you’re about to black out due to a drop in blood pressure

Other medications

  • Norepinephrine (Levophed) – a catecholamine and vasopressor
  • Dihydroergotamine and ergotamine – affect the sympathetic nervous system
  • Dopamine agonists/antagonists
  • Ephedrine, norepinephrine, and fludrocortisone

The choice of medication depends on the underlying cause of hypotension. Adjunctive agents like NSAIDs, caffeine, and MAO inhibitors may also be used. Ongoing monitoring is crucial to identify and manage potential adverse effects or interactions.

High Blood Pressure Cold Medicine

It’s crucial to exercise caution when selecting over-the-counter cold remedies if you have high blood pressure. Many standard cold medicines contain decongestants like pseudoephedrine or phenylephrine that can raise blood pressure by constricting blood vessels. Decongestants work by narrowing the blood vessels in the nasal passages, but this effect can also occur in blood vessels throughout the body, potentially increasing blood pressure.

To safely treat cold symptoms if you have high blood pressure, look for decongestant-free cold medicines specifically formulated for people with hypertension. Some options include:

  • Vicks DayQuil High Blood Pressure Cold & Flu: a non-drowsy multi-symptom medication containing acetaminophen and dextromethorphan
  • Coricidin HBP: decongestant-free cold medicines recommended by pharmacists
  • Vicks NyQuil High Blood Pressure Cold & Flu: a nighttime cold medicine that temporarily relieves common cold and flu symptoms without decongestants

In addition to choosing the right cold medicine, monitor your blood pressure when starting a new medication. Avoid excess salt, which can raise blood pressure, and consult your doctor about any over-the-counter medications you plan to take. Making lifestyle changes like eating healthy, exercising, and quitting smoking can also help prevent and manage high blood pressure.

Are there any natural alternatives to BP medications?

There are several natural alternatives that may help lower blood pressure, but they should be used in addition to, not instead of, prescribed medications:

  • Coenzyme Q10 supplements have been shown to significantly reduce blood pressure in meta-analyses. Patients with hypertension tend to have lower levels of this enzyme.
  • Potassium-rich foods like leafy greens, beans, bananas and avocados may provide mild blood pressure lowering benefits similar to supplements.
  • Certain herbs like mistletoe extract, hawthorn, garlic, ginger, basil and celery seeds may help dilate blood vessels and lower blood pressure, but more research is needed. Consult a doctor before using herbs.
  • Relaxation techniques like meditation, deep breathing, yoga, tai chi and qi gong can activate the parasympathetic nervous system to slow heart rate and lower blood pressure.
  • Lifestyle changes like regular aerobic exercise, weight loss, limiting alcohol and sodium intake, and eating a diet high in fruits, vegetables, whole grains and low-fat dairy can significantly lower blood pressure.

However, it’s crucial to continue taking prescribed blood pressure medications as directed by your doctor. Natural alternatives should only be used in addition to, not instead of, medications. Consult your healthcare provider before making any major changes to your treatment plan.


1: What is the use of Xanax?

Xanax (alprazolam) can lower blood pressure, but it is not an approved treatment for high blood pressure. A 2011 study found that alprazolam was as effective as the blood pressure medication captopril at lowering blood pressure in people with elevated levels. However, long-term use of benzodiazepines like Xanax is generally not recommended due to the risk of dependence.

2: What is Tadalafil and Sildenafil used for?

The drugs Sildenafil (Viagra) and Tadalafil (Cialis) are used for the treatment of erectile dysfunction. While they do not directly lower blood pressure, they can interact with blood pressure medications. Tadalafil and Xanax have the potential for a moderately clinically significant interaction, so they should be used cautiously together. More than 300 medications, including some blood pressure medications, interact with sildenafil.

3: Where Mucinex and NyQuil are used?

Over-the-counter remedies for colds and flu include Mucinex (guaifenesin) and NyQuil (acetaminophen, dextromethorphan, doxylamine). They do not directly affect blood pressure, but some of their ingredients like doxylamine can interact with certain blood pressure drugs.
