Can pregabalin make your heart race?
Yes. Pregabalin can cause cardiovascular side effects in some people, including an increased heart rate (palpitations or a “racing” feeling). People may notice this as faster-than-usual heartbeat, fluttering, or a pounding sensation.
What symptoms should you watch for?
If you feel your heart racing after starting pregabalin or after a dose change, pay attention to accompanying symptoms that can signal a more serious problem, such as:
- chest pain or pressure
- shortness of breath
- dizziness or fainting
- severe or persistent palpitations
If any of these occur, seek urgent medical care.
When is the timing more suspicious?
Heart-racing sensations are more concerning when they happen:
- soon after starting pregabalin
- after increasing the dose
- when combined with other medications or substances that can affect heart rate
Could pregabalin cause palpitations indirectly?
Pregabalin can also cause other effects that may make your heart feel like it’s racing, such as dizziness or changes in how you feel overall. Sometimes the sensation is palpitations rather than a truly dangerous rhythm, but you still need evaluation if it’s new, frequent, or intense.
What should you do if it happens?
- If the palpitations are mild and pass quickly, contact the prescribing clinician promptly for advice about whether to adjust the dose.
- Do not stop pregabalin abruptly without medical guidance, especially if you take it regularly for nerve pain, anxiety, or seizures.
- If you have red-flag symptoms (chest pain, fainting, severe shortness of breath), go to the emergency department.
Could something else be the real cause?
Yes. Heart-racing can also come from anxiety, caffeine/energy drinks, nicotine, dehydration, thyroid problems, anemia, infections, or interactions with other drugs. If this started after pregabalin, it’s still important to tell your clinician so they can sort out whether pregabalin is the trigger and whether you need an ECG or other checks.

Quick check so you can be more specific
If you want, tell me:
1) your pregabalin dose and when you started (or increased it), and
2) whether you have chest pain, dizziness, or shortness of breath,
and I can help you judge how urgently to seek care and what details to share with your clinician.
