Can pregabalin lower (slow) heart rate?
Pregabalin is known to affect the nervous system and can cause side effects such as dizziness, somnolence, and swelling. However, the provided information does not include specific evidence about whether pregabalin slows heart rate (bradycardia). Because of that, it’s not possible to confirm from the given sources that pregabalin reliably reduces heart rate.
What might people interpret as “slowed heart rate” on pregabalin?
Some people may feel like their pulse is slower or weaker while taking pregabalin due to common effects like dizziness or sedation, which can change how heartbeats feel—even if the medication does not directly slow the heart rate.
When to treat this as urgent (even if you’re on pregabalin)
If you are taking pregabalin and notice symptoms that can accompany an abnormally slow heart rate—such as fainting, severe dizziness, chest pain, confusion, or shortness of breath—seek urgent medical care. Also contact a clinician promptly if your measured heart rate is consistently low for you or you feel unwell.
Could pregabalin interact with other medicines?
Pregabalin can interact with other drugs that affect circulation, the nervous system, or breathing. If you take other medications (for example, those for heart rhythm or blood pressure), the combined effect could change heart rate—either directly or indirectly. The provided information does not cover specific interaction details here.
What to do if you think pregabalin is slowing your pulse
If you suspect pregabalin is lowering your heart rate:
- Check your pulse and note symptoms (time started, dose, other meds).
- Contact your prescribing clinician before changing the dose.
- Do not stop pregabalin abruptly without medical guidance.
