Here’s a detailed, evidence-based overview.
Why older adults are more vulnerable
As people age:
- The heart pumps less efficiently.
- The kidneys and liver remove medications more slowly.
- Multiple medications (polypharmacy) increase the chance of interactions.
- Side effects can occur even with normal doses.
Because of this, medications should be reviewed regularly with a healthcare professional.
1. NSAID Pain Relievers
Examples:
- Advil (ibuprofen)
- Motrin
- Aleve
Why they can affect the heart
These medicines may:
- Raise blood pressure
- Cause the body to retain salt and water
- Worsen heart failure
- Increase the risk of heart attack and stroke, particularly with long-term or high-dose use
Older adults with:
- High blood pressure
- Heart failure
- Kidney disease
- Previous heart attack
are at higher risk.
Warning signs
- Swollen ankles
- Rapid weight gain
- Shortness of breath
- Chest pain
Safer approaches
Depending on the cause of pain, options may include:
- Acetaminophen (when appropriate and within recommended doses)
- Physical therapy
- Heat or cold therapy
- Exercise tailored to the individual
- Topical pain relievers
2. Certain Decongestants
Examples
- Pseudoephedrine
- Phenylephrine
These are common in many cold and sinus medicines.
Heart effects
They constrict blood vessels, which can:
- Increase blood pressure
- Increase heart rate
- Trigger irregular heart rhythms
- Worsen angina
People with heart disease should be especially cautious.
Safer options
- Saline nasal spray
- Humidified air
- Adequate hydration
- Other treatments recommended by a healthcare professional
3. Some Diabetes Medications
Most diabetes medications are safe and help reduce cardiovascular risk. However, certain medications may not be suitable for every older adult.
Examples include:
- Some sulfonylureas (which can increase the risk of low blood sugar)
- Certain older medications that may worsen fluid retention in susceptible individuals
Potential problems
- Fluid retention
- Weight gain
- Increased heart failure risk (for specific medications in susceptible people)
- Low blood sugar, which can stress the heart
Today, some newer diabetes medications have been shown to protect the heart rather than harm it.
4. Some Heart Rhythm Medications
Ironically, medications used to treat abnormal heart rhythms can sometimes cause new rhythm problems.
Examples include medications prescribed for:
- Atrial fibrillation
- Ventricular arrhythmias
Possible effects
- Slow heart rate
- New rhythm disturbances
- Dizziness
- Fainting
These medications require careful monitoring.
5. Certain Antibiotics
Some antibiotics can prolong the heart’s electrical recovery time (QT interval), increasing the risk of dangerous rhythm disturbances in susceptible people.
Examples include some:
- Macrolides
- Fluoroquinolones
Risk is higher if someone:
- Has existing heart disease
- Has low potassium or magnesium
- Takes multiple QT-prolonging medications
6. Some Antidepressants and Antipsychotics
Certain medications in these categories may:
- Affect heart rhythm
- Lower blood pressure when standing
- Increase fall risk
- Occasionally contribute to QT prolongation
These medications remain appropriate for many people when prescribed and monitored correctly.
7. Steroids (Corticosteroids)
Examples:
- Prednisone
- Dexamethasone
Long-term use may:
- Raise blood pressure
- Increase blood sugar
- Cause fluid retention
- Increase the workload on the heart
They are often necessary for treating serious inflammatory conditions, so they should not be stopped suddenly without medical guidance.
Symptoms that should never be ignored
Seek prompt medical evaluation if you develop:
- Chest pain
- Sudden shortness of breath
- Fainting
- Rapid or irregular heartbeat
- Severe swelling in the legs
- Sudden unexplained weight gain over a few days
How to protect your heart while taking medications
- Never stop a prescribed medication on your own. Some medicines—especially those for blood pressure, heart rhythm, or steroids—can be dangerous to stop abruptly.
- Keep an up-to-date medication list. Include prescription drugs, over-the-counter medicines, vitamins, and herbal supplements.
- Have regular medication reviews. Older adults benefit from periodic reviews with a doctor or pharmacist to identify unnecessary medications or potential interactions.
- Monitor blood pressure and pulse. Home monitoring can help detect changes early if recommended by your healthcare team.
- Stay hydrated. Dehydration can increase the risk of side effects from several medications.
- Limit unnecessary over-the-counter medications. Even common products for pain, allergies, or colds can interact with prescription drugs.
- Maintain a heart-healthy lifestyle. Regular physical activity, a balanced diet rich in fruits, vegetables, whole grains, and lean proteins, adequate sleep, and avoiding smoking all help support cardiovascular health.
Bottom line
No medication is universally “bad” for seniors’ hearts. Many drugs that can have cardiovascular side effects are also lifesaving when used appropriately. The key is using the right medication, at the right dose, for the right person, with regular monitoring for side effects and interactions. If you or a family member is concerned about a specific medication, discussing it with the prescribing clinician or pharmacist is the safest way to determine whether any changes are needed.
