A Cardiologist Explains 5 Medications That May Increase Heart Risks in Older Adults

As people age, managing multiple health conditions often means taking several medications every day. While many of these medicines are essential and improve quality of life, some can have unintended effects on the heart—especially in older adults. Age-related changes in the body can alter how medications are absorbed, processed, and eliminated, making seniors more vulnerable to side effects and drug interactions.

It’s important to understand that medications should never be stopped without consulting a healthcare provider. In many cases, the benefits outweigh the risks when medicines are used appropriately. However, knowing which medications may affect heart health allows patients and caregivers to ask informed questions and monitor for warning signs.

Why Older Adults Are More Sensitive to Medications

As we age, several changes occur that can influence how the body responds to medication. Kidney and liver function may gradually decline, slowing the breakdown and removal of drugs. Changes in body composition, including reduced muscle mass and increased body fat, can also affect how medications are distributed throughout the body.

Older adults are also more likely to take multiple prescriptions, over-the-counter medicines, and dietary supplements at the same time. This increases the likelihood of drug interactions that may place extra stress on the heart.

Because of these factors, regular medication reviews with a healthcare provider are especially important.

1. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

NSAIDs are commonly used to relieve pain, inflammation, and fever. While they can be effective for arthritis, muscle pain, and other conditions, prolonged or frequent use may pose cardiovascular risks for some older adults.

Examples include:

• Ibuprofen
• Naproxen
• Diclofenac

Why They May Affect the Heart

NSAIDs can cause the body to retain sodium and water, leading to increased blood pressure and additional strain on the heart. In some individuals, especially those with existing cardiovascular disease or heart failure, these medications may increase the risk of heart attack, stroke, or worsening heart failure.

Safer Practices

• Use the lowest effective dose for the shortest possible time.
• Discuss alternative pain management options with your healthcare provider.
• Monitor blood pressure regularly if long-term NSAID use is necessary.

2. Certain Decongestants

Many over-the-counter cold and allergy medications contain decongestants that temporarily relieve nasal congestion.

Common ingredients include:

• Pseudoephedrine
• Phenylephrine

Why They May Affect the Heart

These medications narrow blood vessels to reduce nasal swelling, but they can also increase blood pressure and heart rate. For older adults with hypertension, coronary artery disease, or irregular heart rhythms, this may place additional stress on the cardiovascular system.

Safer Practices

• Read medication labels carefully.
• Consider saline nasal sprays or other non-medicated alternatives when appropriate.
• Consult a healthcare provider before using decongestants if you have heart disease or high blood pressure.

3. Some Diabetes Medications

Managing diabetes is essential for protecting long-term heart health. However, certain diabetes medications may require closer monitoring in older adults, particularly those with heart failure or kidney disease.

Why Monitoring Matters

Some medications may cause fluid retention or increase the risk of heart failure in susceptible individuals. Others may increase the likelihood of low blood sugar, which can place stress on the heart by triggering rapid heartbeat or other cardiovascular symptoms.

The choice of diabetes medication should always be individualized based on a person’s overall health, kidney function, and cardiovascular history.

Safer Practices

• Attend regular follow-up appointments.
• Monitor blood sugar as directed.
• Report swelling, shortness of breath, or unexplained weight gain to your healthcare provider promptly.

4. Certain Stimulant Medications

Some prescription medications used to treat attention disorders or excessive daytime sleepiness have stimulant effects.

Why They May Affect the Heart

Stimulants can increase heart rate and blood pressure. While many people tolerate these medications well, older adults with underlying cardiovascular disease may have a higher risk of complications.

Symptoms that deserve medical attention include:

• Chest pain
• Irregular heartbeat
• Severe shortness of breath
• Fainting

Healthcare providers usually evaluate cardiovascular history before prescribing stimulant medications.

5. Some Antibiotics

Most antibiotics are safe when prescribed appropriately, but a few have been associated with changes in the heart’s electrical activity.

Why They May Affect the Heart

Certain antibiotics may prolong the QT interval, an electrical measurement of heart rhythm. In susceptible individuals, especially those taking multiple medications or who already have heart rhythm disorders, this can increase the risk of serious arrhythmias.

The risk is generally low but may be higher in:

• Older adults
• Individuals with electrolyte imbalances
• People with existing heart disease
• Those taking several medications that affect heart rhythm

Healthcare providers carefully consider these factors when selecting an antibiotic.

Warning Signs You Should Never Ignore

Regardless of the medication you’re taking, seek prompt medical attention if you experience:

• Chest pain or pressure
• Sudden shortness of breath
• Rapid or irregular heartbeat
• Fainting or severe dizziness
• Swelling in the legs or ankles
• Sudden unexplained fatigue
• Difficulty breathing while lying flat

These symptoms may indicate a serious cardiovascular problem that requires immediate evaluation.

Tips for Taking Medications Safely

Older adults can reduce medication-related risks by following several simple habits.

Keep an Updated Medication List

Include:

• Prescription medications
• Over-the-counter medicines
• Vitamins
• Herbal supplements

Share this list during every medical appointment.

Avoid Self-Medicating

Even common pain relievers or cold medicines may interact with prescription medications or affect heart health.

Attend Regular Checkups

Routine medical visits allow healthcare providers to monitor blood pressure, kidney function, heart rhythm, and medication effectiveness.

Take Medications Exactly as Prescribed

Never change the dose or stop a medication without medical guidance. Suddenly discontinuing certain medications can be harmful.

Ask About Drug Interactions

Whenever a new medication is prescribed, ask whether it could interact with your current medications or affect your heart.

Frequently Asked Questions

Should older adults avoid NSAIDs completely?

Not necessarily. Many people use NSAIDs safely when taken for short periods and under medical supervision. Individuals with heart disease, kidney disease, or high blood pressure should discuss the risks with their healthcare provider.

Can over-the-counter medications affect heart health?

Yes. Some non-prescription products, including decongestants and certain pain relievers, can increase blood pressure or interact with prescription medications.

Is it dangerous to take several medications at once?

Taking multiple medications, known as polypharmacy, can increase the risk of drug interactions. Regular medication reviews help reduce unnecessary risks while ensuring that important treatments continue.

Should I stop a medication if I read about possible heart risks?

No. Never stop a prescribed medication without consulting your healthcare provider. Many medications have important benefits, and the risks often depend on your individual health history.

Final Thoughts

Medications play a vital role in helping older adults manage chronic conditions and maintain a good quality of life. However, age-related changes and the use of multiple medications can increase the likelihood of side effects that affect the heart. Certain pain relievers, decongestants, stimulant medications, some diabetes drugs, and a small number of antibiotics may require additional caution, particularly in individuals with existing cardiovascular disease.

The safest approach is to work closely with your healthcare provider, attend regular checkups, and review all medications periodically. Staying informed and communicating openly with your medical team can help reduce risks while ensuring you continue to receive the treatments that best support your overall health.
