Can pregablin (pregabalin) change heart rate?
Pregablin (pregabalin) can affect how the body feels overall, and it may be associated with cardiovascular symptoms in some people, including changes in heart rate. Reports and prescribing information commonly note side effects such as dizziness and palpitations, which can be perceived as a faster or more irregular heartbeat.
What heart-rate symptoms might people notice?
People sometimes describe:
- Palpitations (a noticeable heartbeat)
- Dizziness or lightheadedness that can come with feeling “off” or tachycardic
- Shortness of breath in some situations (which should be taken seriously if it’s new or worsening)
Because pregabalin can also lower blood pressure in some users, the combination of lower BP and dizziness can feel like the heart is racing, even if the actual rhythm hasn’t changed.
When should a heart-rate change be treated as urgent?
Seek urgent care or emergency help if a heart-rate change comes with any of the following:
- Chest pain or pressure
- Fainting or near-fainting
- Severe shortness of breath
- A very fast heart rate that doesn’t settle
- Signs of an allergic reaction (swelling of face/lips, hives, wheezing)
Could other causes explain the change in heart rate?
Yes. Heart rate changes while taking pregablin can also be due to:
- Anxiety or panic symptoms (which can increase heart rate)
- Dehydration or low blood pressure
- Other medicines (including stimulants, antidepressants, decongestants, and some heart or lung medications)
- An underlying heart or rhythm condition that becomes noticeable around the same time
Should you stop pregablin if your heart rate changes?
Do not stop suddenly without medical advice. Pregabalin is usually adjusted gradually to avoid withdrawal symptoms. If your heart-rate symptoms are new, persistent, or getting worse, contact your prescriber promptly so they can check your vital signs and consider dose changes or an alternative.
What information would help your clinician judge it?
If you can, note:
- Your current dose and when you started or changed it
- The heart-rate symptoms (fast, irregular, pounding) and how long they last
- Your blood pressure (if you have it) and any dizziness or fainting
- Any other medications or supplements you take

If you share your country/brand and dose (and whether you’re on any other meds), I can help you narrow what to look for in the official label and discuss likely next steps.
