Can Lyrica (pregabalin) cause a low heart rate?
Lyrica (pregabalin) can be associated with abnormal heart rhythms and slower heart rate in some people. If you’re seeing symptoms like dizziness, fainting, unusual fatigue, chest discomfort, or shortness of breath, treat it as potentially serious and seek urgent medical care—especially if the low heart rate is new after starting or increasing Lyrica.
What would “low heart rate” mean medically when taking Lyrica?
“Low heart rate” usually refers to bradycardia (a heart rate that’s slower than normal). Whether it’s dangerous depends on:
- The actual heart rate value
- Your age and baseline heart rate
- Symptoms (symptoms matter as much as the number)
- Other medications and medical conditions (for example, beta-blockers, some blood pressure meds, heart disease, thyroid problems)
Lyrica use can overlap with other factors that also affect heart rate, so clinicians typically look at the whole medication list and your heart rhythm (often with an ECG).
What symptoms should prompt immediate care?
Get urgent evaluation if low heart rate happens with:
- Fainting or near-fainting
- Severe dizziness
- Chest pain
- Trouble breathing
- Confusion or weakness that feels sudden or out of proportion
Could another medication be the real cause?
Yes. Many common drugs can lower heart rate, including beta-blockers (like metoprolol), certain calcium channel blockers (like verapamil/diltiazem), some antiarrhythmics, and some other agents that slow conduction. If Lyrica was added or the dose increased recently, a timing link can be helpful for your clinician, but interactions and underlying conditions can still be the dominant cause.
What should you do if your heart rate drops after starting or increasing Lyrica?
Practical steps:
- Check whether the low heart rate is persistent or only during sleep.
- Note when it started relative to the Lyrica dose change.
- Contact the prescriber promptly to report the bradycardia and symptoms.
- Avoid changing or stopping Lyrica on your own unless a clinician tells you to—especially if you need the medication for seizure control or severe nerve pain. Your prescriber may recommend a dose adjustment or an alternative.
Does Lyrica affect heart rhythm on an ECG?
Pregabalin has been linked to rhythm-related events reported in clinical practice. If you have bradycardia or symptoms, a clinician may order an ECG to see whether the rhythm is simply slow or if it’s a conduction problem (which changes the urgency and treatment).
Are there alternatives if Lyrica is causing bradycardia?
Your options depend on why you’re taking Lyrica (nerve pain, fibromyalgia, neuropathy, seizures, etc.) and your overall health. Clinicians often consider other treatments for the same condition, but the best switch depends on your diagnosis and other medications.

Quick check: what should you tell your doctor?
To speed up care, share:
- Your heart rate readings (and whether they’re at rest)
- Symptoms (dizziness, fainting, chest pain, shortness of breath)
- Lyrica dose and when it changed
- All other medications, including dose changes
- Any known heart conditions or thyroid issues
If you tell me your age, your Lyrica dose, the heart rate number you’re seeing, and whether you have symptoms, I can help you think through how urgent it is and what questions to ask your clinician.
