Yes, cortisone (corticosteroids) can be bad for your heart, especially with high doses and long-term use, increasing risks for high blood pressure, irregular heart rhythms (arrhythmias), fluid retention, and plaque buildup (atherosclerosis) by affecting blood sugar, lipids, and blood pressure, but low doses for short periods have fewer risks, and benefits often outweigh risks in severe inflammatory conditions. Doctors carefully weigh these risks, managing them with monitoring and lifestyle changes.
Side effects can include:
You should not use cortisone if you are allergic to it, or if you have a fungal infection anywhere in your body. Steroids can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have.
Arrhythmias: Studies have shown that the use of corticosteroids, particularly in high doses, is associated with a greater risk of heart arrhythmia known as atrial fibrillation. In this abnormal heart pattern, the heart beats irregularly, and the blood flow to the brain can be impaired, increasing the risk of stroke.
Cardiac arrhythmias have been reported to occur in 1% to 82% of patients receiving high doses of corticosteroids. These adverse effects, which include atrial fibrillation/flutter, ventricular tachycardias and sinus bradycardia,5 are usually associated with the intravenous route of administration.
Corticosteroid treatment has been previously associated with risk factors for cardiovascular disease such as hypertension, hyperlipidaemia, and hyperglycaemia. Oral corticosteroid treatment may also be an independent risk factor for ischaemic events, particularly during treatment.
Medications such as asthma inhalers, beta-blockers you take for high blood pressure or heart disease, thyroid drugs and antiarrhythmic medicines. Some cough/cold medicines, including decongestants. Some herbal and nutritional supplements. Recreational drug use such as cocaine and amphetamines (speed).
Compared to cortisone injections, PRP therapy offers several advantages: Reduced risk of side effects: PRP is derived from the patient's own blood, minimizing the risk of allergic reactions or other adverse effects.
Prolonged elevations of another stress hormone, called cortisol, also increase blood pressure, as well as blood sugar, cholesterol, and triglycerides. For a person living with chronic stress, the result can be chest pain, irregular heartbeats, shortness of breath, and an increased risk of heart attack and stroke.
Similarly a transient increase in blood pressure can also occur after a cortisone injection although again this typically goes away within 5-7 days after the injection.
Some medicines that corticosteroids could interact with include:
The length of pain relief after a cortisone shot depends on the condition being treated, how long it has been present, and which part of the body is being injected. If a cortisone shot is working for the patient, it can last at least 3 to 6 months, and sometimes longer.
Corticosteroids have a short-term immunosuppressant effect and can make it harder for your body to fight an infection and heal itself. People who take blood-thinning medications (anticoagulants) or have a bleeding disorder (like hemophilia) may not be able to receive steroid injections.
The most painful places for a cortisone shot are typically small, sensitive areas with dense nerve endings, like the palm of the hand, sole of the foot (plantar fascia), fingers, toes, or ankle joints, because they have less space for the medicine and more surface nerves compared to larger joints like the shoulder or knee. Pain is also worse if the tissue is already severely inflamed, and the needle size can play a role.
Symptoms of corticosteroid overdose can include:
Strenuous activity or exercise should be avoided for at least 48 hours after a steroid injection. Returning to normal activities too quickly can reduce the effectiveness of the treatment. Activities to avoid: Running or jogging.
Earlier studies reported that supplementation with vitamin D lowers cortisol levels, particularly in populations with underlying health conditions [Demay et al., 2024].
“When stress hormones are elevated, your blood pressure may rise and you may feel heart palpitations, a racing heartbeat, shortness of breath, or even chest pain. In extreme cases, stress can also cause the heart to temporarily weaken, a condition called stress-induced cardiomyopathy.”
So, when cortisol rises at 2-3 a.m., it triggers the sympathetic nervous system, leading to an increased heart rate and blood pressure—factors that can make you wake up earlier than planned, and much harder to fall back asleep.
While there's no single "strongest," Omega-3 fatty acids (from fatty fish) and curcumin (from turmeric) are consistently cited as highly potent natural anti-inflammatories, alongside powerful antioxidants from fruits and vegetables like blueberries, plus herbs like ginger and garlic, all working to reduce inflammation pathways. A comprehensive anti-inflammatory diet emphasizes these foods, though Omega-3s and curcumin often stand out for their significant impact.
Long-Term Use Risks Long-term use of oral steroids can lead to more severe health complications, such as osteoporosis, adrenal insufficiency, or diabetes. In contrast, corticosteroid injections often have fewer long-term risks when used appropriately.
If the initial cortisone shot didn't work, your doctor may recommend trying steroid injections. Steroid injections use a different type of steroid than cortisone to reduce inflammation and pain. These injections are usually given directly into the joint or the surrounding tissue.
To calm heart palpitations, use relaxation techniques like deep breathing or meditation, avoid triggers like caffeine and nicotine, and try vagal maneuvers like splashing cold water on your face or bearing down, but see a doctor if you have chest pain, shortness of breath, or fainting, as these can signal a serious issue.
