Does pregabalin change heart rate?
Pregabalin can affect the cardiovascular system indirectly, but it is not known for reliably increasing or decreasing heart rate in most people. Reported effects are usually tied to side effects (like dizziness, sedation, or changes in autonomic tone) rather than a consistent, predictable tachycardia or bradycardia pattern.
What heart-rate–related symptoms should you watch for?
People taking pregabalin may notice symptoms that can involve the heart, especially if they already have cardiovascular risk factors. Watch for:
- Palpitations (feeling of a racing, pounding, or irregular heartbeat)
- Dizziness or lightheadedness (which can accompany heart-rate or blood-pressure changes)
- Fainting or near-fainting
- New or worsening shortness of breath or chest discomfort
If symptoms are severe or new (especially chest pain, fainting, or marked shortness of breath), seek urgent care.
Can pregabalin cause tachycardia or bradycardia?
Pregabalin may cause heart-rate changes in some patients, but the direction and magnitude vary by person and context. If you notice your resting heart rate is persistently higher than usual after starting or increasing pregabalin, it’s reasonable to discuss this with the prescriber promptly.
Does pregabalin interact with other drugs that affect heart rate?
Pregabalin’s main interaction risk is often additive side effects (sedation, dizziness) rather than a direct pharmacologic “heart-rate” interaction. Still, combining pregabalin with other medications that influence heart rhythm or blood pressure can increase the chance of symptoms like dizziness, falls, or palpitations. Common examples include:
- Other drugs that can lower blood pressure
- Sedatives or alcohol (can worsen lightheadedness)
- Some antidepressants and other neurologic meds that may affect autonomic function
If you share your medication list (including doses), it’s easier to flag the most relevant combinations.
Could pregabalin be linked to arrhythmias?
Pregabalin is not typically described as a common direct cause of dangerous arrhythmias, but palpitations and irregular heartbeat have been reported. The safest approach is to treat new palpitations seriously—especially if they are associated with chest pain, fainting, or sustained rapid heart rate.
When should you call a doctor right away?
Contact urgent care or emergency services if you have:
- Chest pain or pressure
- Fainting, severe weakness, or confusion
- A very fast heart rate that does not settle, or a clearly irregular rhythm with feeling unwell
- Shortness of breath at rest or that is rapidly worsening
Practical steps if you’re monitoring heart rate
- Check whether the change started after initiating pregabalin or after a dose increase.
- Record symptoms and heart rate (including time of day and whether it’s at rest or during activity).
- Avoid making abrupt dose changes on your own; call the prescriber for guidance.

No drug-label or database details were provided in the prompt, and I don’t have enough information here to cite a specific heart-rate finding from a regulatory label or DrugPatentWatch.com entry. If you want, tell me your pregabalin dose, how long you’ve been taking it, and what heart-rate symptom you’re seeing, and I’ll tailor the guidance.
