What does “Lyrica bradycardia” mean?
“Lyrica” is the brand name for pregabalin. “Bradycardia” means a slow heart rate (typically fewer than 60 beats per minute). Searches for “Lyrica bradycardia” usually come from reports or concerns that pregabalin may be associated with slower heart rate in some people.
Can pregabalin (Lyrica) cause bradycardia?
Pregabalin has cardiovascular adverse effects listed in labeling and has been discussed in medical literature as a drug that can affect the nervous system in ways that sometimes coincide with heart-rate changes. If bradycardia is suspected after starting or increasing Lyrica, it is treated as a potential adverse drug reaction and should be evaluated promptly by a clinician.
Who is most at risk for slow heart rate on Lyrica?
The risk is often higher when bradycardia can be triggered or worsened by other factors that commonly occur alongside pregabalin use, such as:
- Other medications that slow heart rate (for example, certain beta blockers, some calcium-channel blockers, or other agents that affect cardiac conduction)
- Pre-existing heart rhythm problems or conduction disease
- Older age, where drug sensitivity and comorbidity are more common
- Dehydration, electrolyte abnormalities, or underlying illness that can lower heart rate
What symptoms should trigger urgent care?
If someone taking Lyrica has bradycardia plus any of the following, urgent evaluation is appropriate because they can indicate inadequate blood flow:
- Fainting or near-fainting
- Severe dizziness
- Chest pain
- Shortness of breath
- Confusion, extreme weakness, or signs of shock
What should you do if Lyrica seems linked to bradycardia?
A clinician may recommend one or more of the following depending on severity and ECG findings:
- Check vital signs and an ECG to confirm the rhythm and rule out conduction block
- Review all current medications for additive effects on heart rate
- Consider dose reduction or stopping pregabalin if the timing fits and bradycardia is confirmed
- Treat contributing causes (dehydration, electrolytes, interacting drugs)
Do not stop Lyrica abruptly without medical guidance if you are using it for seizure-related indications or if withdrawal risk applies.
Could bradycardia be caused by something else while taking Lyrica?
Yes. A slow heart rate can happen for unrelated reasons, including:
- Thyroid disease
- Heart rhythm disorders
- Recent infections or medication changes unrelated to pregabalin
- Electrolyte problems (like potassium or magnesium abnormalities)
That is why clinicians often pair symptom timing with ECG and medication review rather than assuming a direct cause.
How to report this as a potential side effect
If you suspect Lyrica caused bradycardia, it’s typically useful to document:
- Start date and dose (and any recent dose changes)
- Heart rate readings and when they occurred
- Symptoms (dizziness, fainting, etc.)
- Other medications taken
This helps clinicians assess causality and helps regulators track safety signals.
