High blood pressure - medicine-related
Drug-induced hypertension is high blood pressure caused by a chemical substance or medicine.
Hypertension - medication related; Drug-induced hypertension
Blood pressure is determined by the:
- Amount of blood the heart pumps
- Condition of the heart valves
- Pulse rate
- Pumping power of the heart
- Size and condition of the arteries
There are several types of high blood pressure:
- Essential hypertension has no cause that can be found (many different genetic traits contribute to essential hypertension, each one having a relatively small effect).
- Secondary hypertension occurs because of another disorder.
- Drug-induced hypertension is a form of secondary hypertension caused by a response to a chemical substance or medicine.
- Pregnancy-induced hypertension.
Chemical substances and medicines that can cause high blood pressure include:
- Alcohol, amphetamines, ecstasy (MDMA and derivatives), and cocaine
- Angiogenesis inhibitors (including tyrosine kinase inhibitors and monoclonal antibodies)
- Antidepressants (including venlafaxine, bupropion, and desipramine)
- Black licorice
- Caffeine (including the caffeine in coffee and energy drinks)
- Corticosteroids and mineralocorticoids
- Ephedra and many other herbal products
- Estrogens (including birth control pills)
- Immunosuppressants (such as cyclosporine)
- Many over-the-counter medicines such as cough/cold and asthma medicines, particularly when the cough/cold medicine is taken with certain antidepressants, such as tranylcypromine or tricyclics
- Migraine medicines
- Nasal decongestants
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Phentermine (a weight loss medicine)
- Testosterone and other anabolic steroids and performance-enhancing drugs
- Thyroid hormone (when taken in excess)
- Yohimbine (and Yohimbe extract)
Rebound hypertension occurs when blood pressure rises after you stop taking or lower the dose of a drug (typically a medicine to lower high blood pressure).
- This is common for medicines that block the sympathetic nervous system like beta blockers and clonidine.
- Talk to your provider to see if your medicine needs to be gradually tapered before stopping.
Many other factors can also affect blood pressure, including:
- Condition of the kidneys, nervous system, or blood vessels
- Foods eaten, weight, and other body-related variables, including the amount of added sodium in processed foods
- Levels of various hormones in the body
- Volume of water in the body
