Can pregabalin raise heart rate in people taking it?
Yes. Pregabalin can increase heart rate in some people. In clinical use, it is associated with cardiovascular effects that can include tachycardia (a faster heart rate), particularly in susceptible patients or at higher doses.
What kinds of heart-rate changes are reported with pregabalin?
Reports include a faster pulse (tachycardia). People may also notice palpitations or a “racing heart,” which can be related to increased heart rate. If pregabalin causes or worsens symptoms like chest discomfort, fainting, or severe shortness of breath, it needs urgent medical evaluation.
Who is more likely to notice heart-rate changes?
The risk is harder to quantify from general information alone, but heart-rate effects are more concerning if you have:
- Existing heart rhythm problems
- Significant heart disease
- Dehydration or electrolyte issues
- Higher pregabalin doses or rapid dose increases
- Other medications that also affect heart rate
Could pregabalin interact with other drugs that affect pulse?
Yes. Pregabalin can be used alongside other medicines that influence cardiovascular status. If you take drugs that affect heart rhythm or heart rate (for example, stimulants, some antidepressants, or other central nervous system medications), the combined effects can make a pulse increase more noticeable.
When should someone contact a clinician?
Seek prompt medical advice if you notice:
- Persistent heart rate increase or recurrent palpitations after starting pregabalin or changing the dose
- Symptoms such as dizziness, chest pain, fainting, or significant shortness of breath
Are there alternatives if pregabalin is causing symptoms?
That depends on why you’re taking it (nerve pain, fibromyalgia, anxiety/other off-label uses) and your medical history. A clinician can adjust the dose, slow titration, or consider an alternative medication if pregabalin-linked tachycardia is suspected.

I don’t have specific citation links from the provided materials for pregabalin and heart-rate increase (tachycardia) in this chat. If you share the country you’re in and whether you want evidence from the drug label, clinical trials, or post-marketing reports, I can tailor the answer accordingly.
