Feeling fatigued is a common side effect of many heart medications, especially beta-blockers and ACE inhibitors. While these medications are crucial for managing conditions like high blood pressure, heart disease, and heart failure, the resulting tiredness can make it challenging to maintain an active lifestyle. Fortunately, there are ways to manage this fatigue and regain your energy levels.
In this blog, we’ll explore why heart medications can cause fatigue, provide practical tips for combating tiredness, and discuss when you should talk to your doctor about adjusting your treatment.
Why Do Heart Medications Cause Fatigue?
Heart medications work by altering the way your heart and blood vessels function to improve overall cardiovascular health. While these changes are beneficial, they can also affect your energy levels. For example, beta-blockers slow down your heart rate and reduce the force of each contraction, which can lead to a feeling of sluggishness or fatigue.
Fact: According to the American Heart Association (AHA), fatigue is one of the most frequently reported side effects of heart medications, affecting nearly 30% of people taking these drugs?source: AHA?.
Let’s look at some of the most common heart medications associated with fatigue and why they cause this side effect.
Heart Medications That Commonly Cause Fatigue
Certain types of heart medications are more likely to cause fatigue than others due to their effects on heart rate, blood pressure, and overall cardiovascular function. Here are the main culprits:
1. Beta-Blockers
Beta-blockers, also known as beta-adrenergic blocking agents, are often prescribed to treat high blood pressure, arrhythmias, and heart failure. They work by blocking the effects of adrenaline, slowing down your heart rate, and reducing the force of each contraction.
Why They Cause Fatigue: By slowing down the heart rate and reducing blood pressure, beta-blockers decrease the amount of oxygen your body receives. This can result in a feeling of tiredness or sluggishness, especially when you first start taking them.
Commonly Prescribed Beta-Blockers:
- Atenolol (Tenormin)
- Metoprolol (Lopressor, Toprol-XL)
- Propranolol (Inderal)
- Carvedilol (Coreg)
2. ACE Inhibitors
ACE inhibitors, or Angiotensin-Converting Enzyme inhibitors, are used to lower blood pressure and improve heart function. They work by relaxing blood vessels, reducing blood pressure, and making it easier for the heart to pump blood.
Why They Cause Fatigue: By lowering blood pressure, ACE inhibitors can sometimes reduce blood flow to muscles and organs, leading to tiredness or dizziness.
Commonly Prescribed ACE Inhibitors:
- Lisinopril (Prinivil, Zestril)
- Ramipril (Altace)
- Enalapril (Vasotec)
- Captopril (Capoten)
3. Calcium Channel Blockers
Calcium channel blockers help relax and widen blood vessels, reducing blood pressure and decreasing the heart’s workload. They are often prescribed for people with high blood pressure or angina.
Why They Cause Fatigue: By lowering blood pressure, calcium channel blockers can sometimes cause a drop in energy levels, leading to tiredness or fatigue.
Commonly Prescribed Calcium Channel Blockers:
- Amlodipine (Norvasc)
- Diltiazem (Cardizem)
- Nifedipine (Procardia)
Tips for Managing Fatigue from Heart Medications
If your heart medication is causing fatigue, there are several strategies you can try to boost your energy levels and reduce tiredness. Here are some practical tips to help you feel more energetic:
1. Take Your Medication at Night
If your medication causes daytime drowsiness, try taking it before bedtime (if recommended by your doctor). This can help minimize fatigue during the day and allow you to get a better night’s sleep.
What You Can Do:
- Talk to your doctor about adjusting your medication schedule.
- Take your medication at the same time every night to maintain consistency.
2. Stay Active with Gentle Exercises
While it may seem counterintuitive, light exercise can help combat fatigue by increasing your energy levels and improving blood circulation. Activities like walking, yoga, or stretching can make a big difference in how you feel.
What You Can Do:
- Start with low-impact exercises like walking, cycling, or yoga.
- Gradually increase the intensity and duration of your workouts as your energy levels improve.
Tip: Aim for at least 30 minutes of moderate exercise most days of the week to reap the benefits.
3. Eat a Balanced Diet
A healthy diet can provide the nutrients your body needs to combat fatigue and support heart health. Focus on eating a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats.
What You Can Do:
- Include foods rich in iron and B vitamins, such as leafy greens, beans, and lean meats, to support energy levels.
- Avoid sugary foods and caffeine, which can cause energy crashes later in the day.
4. Stay Hydrated
Dehydration can worsen fatigue and make it harder for your body to process medications. Drink plenty of water throughout the day to stay hydrated and support overall health.
What You Can Do:
- Carry a water bottle with you and take small sips throughout the day.
- Limit your intake of dehydrating beverages like alcohol or caffeinated drinks.
5. Get Enough Sleep
Quality sleep is essential for managing medication-related fatigue. Aim for 7-9 hours of sleep each night to give your body the rest it needs.
What You Can Do:
- Establish a regular sleep schedule by going to bed and waking up at the same time every day.
- Create a relaxing bedtime routine, such as reading, meditating, or taking a warm bath, to help you wind down.
6. Monitor Your Symptoms and Talk to Your Doctor
If fatigue persists or worsens, or if it significantly impacts your quality of life, talk to your doctor. They may adjust your dosage, change your medication, or recommend other strategies to reduce fatigue.
What You Can Do:
- Keep a diary of your symptoms, including when they occur and how severe they are.
- Bring your diary to your doctor’s appointment to help guide the discussion.
When to Talk to Your Doctor About Fatigue
While mild fatigue is a common side effect of heart medications, severe or persistent tiredness should be addressed with your healthcare provider. Talk to your doctor if:
- Fatigue interferes with your daily activities: If you’re struggling to stay awake during the day or unable to perform routine tasks, it’s time to seek help.
- You notice other symptoms: If you experience symptoms like dizziness, shortness of breath, or chest pain along with fatigue, contact your doctor immediately.
- You’re considering stopping your medication: Never stop taking your medication suddenly without consulting your doctor, as this can lead to serious health complications.
Your doctor may adjust your dosage, switch you to a different medication, or suggest lifestyle changes to help reduce fatigue without compromising your heart health.
Can You Switch to a Different Medication?
If fatigue from your current heart medication is affecting your quality of life, your doctor may recommend switching to a different medication. For example:
- If you experience severe fatigue with beta-blockers, your doctor may switch you to a calcium channel blocker or ACE inhibitor.
- If you’re taking an ACE inhibitor and experience fatigue, your doctor may consider an ARB (Angiotensin II Receptor Blocker), which has a similar effect on blood pressure without causing as much fatigue.
Always discuss any changes in your medication with your healthcare provider, and never switch or stop your medication without medical guidance.
Additional Strategies to Boost Energy Levels
In addition to managing fatigue through diet, exercise, and sleep, consider these strategies to increase your energy levels:
1. Take Breaks Throughout the Day
Short breaks can help you recharge and prevent burnout. Take a few minutes to stretch, walk around, or practice deep breathing.
2. Engage in Relaxation Techniques
Stress can worsen fatigue, so consider incorporating relaxation techniques like meditation, deep breathing, or progressive muscle relaxation into your routine.
3. Connect with Others
Social interactions can boost your mood and energy levels. Spend time with family and friends or consider joining a support group for people with heart conditions.
In Conclusion
Fatigue from heart medications like beta-blockers and ACE inhibitors is a common side effect, but it doesn’t have to disrupt your life. By understanding why these medications cause fatigue and implementing strategies to manage tiredness, you can improve your energy levels and maintain your heart health.
If fatigue is affecting your daily activities or quality of life, don’t hesitate to talk to your doctor. With the right support and management, you can stay on track with your heart treatment and lead a healthier, more active life.
