Can Lyrica (pregabalin) change heart rate?
Lyrica (pregabalin) can affect how the body’s nervous system controls heart rhythm and heart-related sensations, but it is not primarily classified as a medication that commonly “drives” heart-rate changes in most patients. People sometimes notice palpitations or a faster heart rate after starting or changing the dose.
Because “heart rate” can mean different things (a temporary increase, a persistent fast rate, or irregular beats), the right next step depends on what you’re experiencing (for example, racing pulse vs. skipped beats).
What heart-related symptoms should trigger urgent care?
Seek urgent medical care if you have any of the following while taking Lyrica:
- Chest pain or pressure
- Fainting, near-fainting, or severe dizziness
- Shortness of breath
- A very fast heart rate that does not settle
- Palpitations with weakness or lightheadedness
- Signs of a serious allergic reaction (swelling of face/lips, hives, trouble breathing)
If symptoms are less severe but new or worsening, contact the prescriber promptly.
How does pregabalin theoretically affect pulse or palpitations?
Pregabalin acts on the nervous system (it reduces release of certain neurotransmitters by binding to the alpha-2-delta subunit of voltage-gated calcium channels). Through nervous system effects, that can sometimes translate into sensations like palpitations, though the exact mechanism for an individual person’s heart-rate symptoms varies.
Could it be from something else happening alongside Lyrica?
Heart-rate changes after starting Lyrica are sometimes due to factors that coincide with the prescription, such as:
- Dose increases or starting at too high a dose for your body
- Other meds that affect heart rhythm or blood pressure
- Caffeine, nicotine, stimulants, decongestants
- Anxiety or pain flares that improve later or worsen during titration
- Dehydration or illness
- Underlying heart conditions
Reviewing all medications and doses with a clinician can clarify the likely cause.
Does Lyrica raise or lower resting heart rate?
Patients report both directions (increased heart rate/palpitations in some cases, and less often a lower or more “settled” pulse as symptoms improve). The key pattern clinicians look for is whether the change is:
- New soon after starting or after a dose change,
- Persistent, and/or
- Accompanied by warning symptoms (chest pain, fainting, severe shortness of breath).
What should you do if your heart rate changes on Lyrica?
If you notice palpitations or a higher pulse:
- Check your pulse when symptoms occur and write down the rate and timing.
- Avoid changing the dose on your own, since abrupt changes can worsen other symptoms.
- Contact the prescriber for guidance, especially after a dose increase or if the symptoms are recurring.
If you have red-flag symptoms, go to urgent care or emergency care.
Which dose and timing changes are most likely to be linked?
If your heart-rate symptoms started right after:
- initiating Lyrica,
- increasing the dose,
- switching formulations,
then the temporal link makes it more likely pregabalin is involved. That’s still not certain, but it’s an important clue for your clinician.
What information to give your doctor
Bring or share:
- Your Lyrica dose and when you started or increased it
- Your usual heart rate vs. the heart rate during symptoms
- Whether the rhythm feels fast, skipped, or irregular
- Any symptoms (dizziness, chest discomfort, shortness of breath)
- A list of all other medications/supplements
This helps determine whether you need an ECG, labs, or a medication adjustment.
Is there a reference source for Lyrica’s heart-rate/palpitations risk?

If you tell me your Lyrica dose (mg), how long you’ve been on it, and the heart-rate number you’re seeing (and whether it feels regular or irregular), I can help you interpret what’s most consistent with medication-related palpitations versus other causes.
