Does pregabalin affect heart rate?
Pregabalin can affect the heart rate, but most people do not experience a persistent increase or decrease. When heart-rate–related side effects happen, they tend to be reported as palpitations or a faster heartbeat (tachycardia), rather than as a clearly predictable change.
What heart-rate symptoms are associated with pregabalin?
People taking pregabalin sometimes report symptoms that can feel like changes in heart rate, such as:
- Palpitations (awareness of heartbeat)
- Feeling like the heart is racing
- Dizziness or lightheadedness that may accompany fast/irregular beats
If you are seeing measured changes on a pulse/heart-rate monitor, it is still safest to treat that as clinically meaningful—especially if it is new, worsening, or accompanied by chest pain, fainting, or shortness of breath.
When should you get urgent care?
Seek urgent medical attention if pregabalin is associated with any of the following:
- Chest pain or pressure
- Fainting or near-fainting
- Severe shortness of breath
- Sustained very fast heart rate, or a heart rhythm that feels irregular and does not settle
- Signs of an allergic reaction (swelling of face/lips, hives, trouble breathing)
What can make pregabalin-related heart-rate symptoms worse?
Heart-rate complaints with pregabalin are more likely to be noticed or can be amplified by factors such as:
- Dehydration or low blood pressure
- Other medicines that affect heart rhythm or blood pressure
- Electrolyte problems (for example, low potassium or magnesium)
- Underlying heart disease, thyroid disease, or anxiety/panic symptoms
- Dose increases or starting pregabalin at a higher-than-usual dose
How quickly can pregabalin change heart rate?
If pregabalin is going to cause noticeable palpitations or tachycardia-like symptoms, it often appears around the time of starting the medication or after a dose change. Persistent or progressive symptoms are a reason to contact a clinician promptly.
Can pregabalin be the cause if my heart rate is high?
It can be, but it’s not the only possibility. High heart rate can also come from pain, fever, infection, dehydration, caffeine/nicotine, stimulant medications, withdrawal from other sedatives, atrial arrhythmias, or anxiety. The most useful approach is to note timing (start/dose change), measure heart rate during symptoms, and tell a clinician what changed and when.
What should you do if you notice a faster heart rate on pregabalin?
- Check your pulse during symptoms and write down the readings and timing (resting vs. after activity).
- Do not stop pregabalin abruptly without medical advice, but contact the prescriber for guidance if symptoms are new or significant.
- Avoid adding other stimulants (extra caffeine, decongestants like pseudoephedrine) until you’ve spoken with a clinician.
