Does Lyrica (pregabalin) slow heart rate?
Lyrica (pregabalin) can affect heart rhythm and pulse in some people. The product information and safety references commonly note cardiovascular effects such as dizziness, bradycardia (slow heart rate), and rhythm changes, particularly in people with other risk factors or who take other medicines that also slow the heart.
What causes Lyrica to lower pulse or worsen heart rhythm?
Pregabalin works on the nervous system (it reduces the release of certain excitatory neurotransmitters). In some patients, that can translate into effects on autonomic control (the body’s “automatic” heart-rate regulation), which may show up as slower heart rate or palpitations. Risk also rises when Lyrica is combined with drugs that depress heart rate or slow conduction.
When should patients call a doctor?
Get medical advice promptly if Lyrica is associated with symptoms such as fainting, near-fainting, severe dizziness, shortness of breath, new chest discomfort, or a consistently very low heart rate. If these are severe or sudden, seek emergency care.
What other medications raise the risk of slow heart rate with Lyrica?
The risk can increase when Lyrica is used alongside other agents that can lower heart rate or affect cardiac conduction, for example:
- beta-blockers (like metoprolol, propranolol)
- calcium channel blockers that slow the heart (like verapamil, diltiazem)
- certain antiarrhythmics
- other sedating medicines that can worsen dizziness/falls (which can be mistaken for “heart” symptoms)
How to monitor heart rate while taking Lyrica
Patients who notice unusual symptoms should check their pulse and document:
- heart rate (how low it goes)
- timing relative to starting or changing the dose
- associated symptoms (dizziness, fainting, palpitations)
Share this with the prescriber so the dose can be adjusted or the medication changed if needed.
Is there a difference between “slow heart rate” and “heart rhythm problems”?
Yes. Bradycardia means the pulse is slow. Heart rhythm problems can involve irregular timing (arrhythmia) even if the pulse rate is not extremely low. Both can cause dizziness or faintness, so symptoms matter as much as the number on a monitor.
