Hypertension, also known as high blood pressure, is a chronic medical condition where the force of blood against the walls of arteries is consistently elevated. It is a major risk factor for heart disease, stroke, and kidney failure. Hypertension is often asymptomatic, which means people with the condition may not experience any noticeable symptoms. It is a prevalent health condition, affecting millions of people worldwide. The causes of hypertension are numerous, and one of the significant contributors is the use of certain medications.
Many drugs can cause hypertension as a side effect, and it is essential to be aware of these potential side effects when taking medication. In this article, we will explore the various medications that can cause hypertension as a side effect and how they do so.
Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
NSAIDs are commonly used to treat pain and inflammation. However, they can cause hypertension by decreasing the effectiveness of blood pressure-lowering medications such as diuretics, ACE inhibitors, and beta-blockers. NSAIDs also cause sodium and water retention, which increases blood volume and, subsequently, blood pressure.
Oral Contraceptives
Oral contraceptives, commonly known as birth control pills, contain hormones that can raise blood pressure in some women. The risk of hypertension is higher in women who are overweight, smoke, or have a family history of hypertension. The risk is also higher in women who take higher doses of estrogen.
Decongestants
Decongestants such as pseudoephedrine are commonly used to relieve nasal congestion. However, they can cause hypertension by constricting blood vessels and increasing blood pressure. Decongestants should be used cautiously by individuals with hypertension or those taking blood pressure-lowering medications.
Steroids
Steroids such as prednisone are commonly used to treat inflammatory conditions such as arthritis, asthma, and lupus. However, steroids can cause hypertension by increasing blood volume, constricting blood vessels, and interfering with the body's ability to regulate sodium and water balance.
Antidepressants
Antidepressants such as selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) can cause hypertension by increasing blood pressure through various mechanisms. SSRIs can increase levels of serotonin in the body, leading to vasoconstriction and increased blood pressure. TCAs can also cause vasoconstriction and increase blood pressure.
Immunosuppressants
Immunosuppressants such as cyclosporine and tacrolimus are commonly used to prevent rejection after organ transplant. However, they can cause hypertension by increasing blood volume, vasoconstriction, and interfering with the body's ability to regulate sodium and water balance.
Stimulants
Stimulants such as amphetamines and cocaine can cause hypertension by constricting blood vessels and increasing heart rate and blood pressure. These drugs should be avoided by individuals with hypertension or those at risk of developing hypertension.
Antipsychotics
Antipsychotics such as risperidone and olanzapine can cause hypertension by increasing blood pressure through various mechanisms. These drugs can cause weight gain, which can increase blood pressure. They can also cause vasoconstriction and interfere with the body's ability to regulate sodium and water balance.
Erythropoietin
Erythropoietin is a hormone that stimulates the production of red blood cells. It is commonly used to treat anaemia in individuals with chronic kidney disease. However, erythropoietin can cause hypertension by increasing blood volume and viscosity, leading to increased blood pressure.
Conclusion:
It is important to be aware of the potential side effects of drugs that can cause hypertension. Certain medications such as corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), and some antidepressants can increase blood pressure levels in some individuals. Patients who are at risk of hypertension or have a history of high blood pressure should be monitored closely by their healthcare provider when taking these medications. It is important to communicate any changes in blood pressure or any symptoms of hypertension to your doctor, as they may need to adjust your medication or treatment plan. By staying informed and proactive about your health, you can better manage the risks associated with medication-induced hypertension and maintain optimal blood pressure levels.
