Does pregabalin change heart rate?
Pregabalin can affect parts of the nervous system that also influence cardiovascular function, but it does not reliably cause a consistent, predictable increase or decrease in heart rate for everyone. In clinical experience and safety reporting, heart-rate–related effects are generally not the most common side effects, yet palpitations (a sensation of a faster or irregular heartbeat) and other cardiovascular symptoms can occur in some people.
What heart-related side effects are reported with pregabalin?
People taking pregabalin sometimes report symptoms that may be linked to heart rate changes, such as:
- Palpitations (feeling like the heart is racing or skipping)
- Dizziness or lightheadedness, which can be confused with heart-rate changes
- Peripheral edema (swelling), which can indirectly affect how someone feels their heartbeat
If you’re using pregabalin and you notice new palpitations, a sustained fast heart rate, chest pain, fainting, or shortness of breath, seek urgent medical care because these can signal problems beyond a medication effect.
Who is more likely to notice heart-rate effects?
Heart-rate sensations may be more noticeable if you:
- Have pre-existing heart rhythm problems (arrhythmias)
- Take other medications that affect heart rhythm or blood pressure
- Are dehydrated or have electrolyte issues
- Start pregabalin at a dose that’s too high for you or increase the dose quickly
Does pregabalin interact with other drugs that affect heart rate?
Pregabalin is often used alongside other medicines for nerve pain, anxiety, or seizures. Heart-rate symptoms can be harder to interpret when combined with drugs that also affect the heart (for example, certain antidepressants, beta-blockers, antiarrhythmics, stimulants) or drugs that lower blood pressure. A clinician or pharmacist can check your specific medication list for additive effects.
When should you contact a doctor about pregabalin and heart symptoms?
Contact a clinician promptly if you develop:
- New or worsening palpitations
- A sustained resting heart rate that’s higher than your normal
- Irregular heartbeat sensations that persist
- Dizziness that comes with near-fainting or fainting
Get emergency care for chest pain, severe shortness of breath, or fainting.
Can pregabalin be stopped safely if it seems to affect your heart?
Do not stop pregabalin abruptly without medical advice. Tapering is typically used to reduce withdrawal risk. If you suspect heart-rate effects, your prescriber can adjust the dose or switch therapies.
What should you do right now if your heart feels “off” on pregabalin?
If you can, check your pulse and note:
- How fast it is (resting rate)
- Whether it feels regular or irregular
- When it started and whether it followed a dose change
Share this information with a clinician, especially if symptoms are persistent or intense.
