How does pregabalin affect heart rate?
Pregabalin can increase heart rate in some people. Reports of palpitations and a faster pulse are consistent with known side effects seen across its safety profile, where cardiovascular symptoms like tachycardia have been described.
Who is more likely to notice a faster heart rate on pregabalin?
People may be more likely to notice heart-rate changes if they:
- start pregabalin at a dose that’s too high for them or increase the dose quickly
- already have a heart rhythm problem or significant cardiovascular disease
- take other medicines that can also raise heart rate (some antidepressants, stimulants, decongestants, and other drugs that affect the autonomic system)
- have dehydration, fever, anxiety, or stimulant/caffeine use at the same time
When is a higher heart rate on pregabalin a warning sign?
A faster heart rate becomes more concerning if it comes with symptoms such as chest pain, fainting, severe shortness of breath, or a very irregular heartbeat. In those situations, urgent medical evaluation is appropriate.
If the increase is mild (for example, a slight rise at rest) and happens soon after starting or after a dose change, it’s still worth contacting the prescriber promptly to discuss whether the dose should be adjusted or if an interaction or underlying issue should be checked.
What can you do if pregabalin raises your pulse?
Common next steps clinicians consider include:
- checking whether the symptom began after a dose increase
- reviewing all other medications and supplements for interactions
- assessing hydration, caffeine/stimulant intake, anxiety, and other triggers
- adjusting the dose or slowing titration if appropriate
- evaluating for rhythm problems (often with an exam and possibly an ECG) if symptoms are persistent or significant
Does pregabalin lower blood pressure or cause dizziness instead?
Yes—pregabalin can also cause dizziness and can affect blood pressure in some people. That means some patients may feel “racy” or unsteady even if the main change is not blood pressure. If you’re experiencing dizziness plus fast heart rate, it’s safer to get medical advice rather than assuming it’s harmless.
How to talk to your doctor about this symptom
Tell your clinician:
- when you started pregabalin and the current dose
- when the heart-rate increase started (and whether it correlates with a dose change)
- your typical resting heart rate vs what you’re seeing now
- any related symptoms (palpitations, chest discomfort, shortness of breath, fainting)
- all other medications (including over-the-counter decongestants and stimulants)

If you want, share the dose, your other medications, and what heart-rate range you’re seeing, and I can help interpret how urgent it may be and what to ask your prescriber.
