Can Lyrica (pregabalin) cause heart problems?
Lyrica (pregabalin) can affect the cardiovascular system in some people, so heart-related side effects are possible. Documented concerns include new or worsening swelling (edema) and, in some cases, effects that can overlap with heart-failure symptoms. Because pregabalin can also cause dizziness and low blood pressure in some patients, it may worsen conditions that already strain the heart.
If you have a history of heart disease, heart failure, or rhythm problems, it’s important to discuss Lyrica with your clinician and report any new symptoms promptly.
What heart-related side effects should people watch for?
People taking Lyrica should seek medical advice quickly if they develop signs that could point to a cardiovascular problem, including:
- New or worsening shortness of breath, especially when lying down
- Swelling in the legs, ankles, or feet
- Rapid weight gain over a short period (from fluid retention)
- Chest pain or pressure
- Fainting, severe dizziness, or feeling like the heart is racing/irregular
These symptoms can signal fluid buildup or other complications that may require stopping or adjusting the medication under medical supervision.
Who is at higher risk?
Risk can be higher for people who already have conditions that affect fluid balance or heart function, such as heart failure, significant kidney problems (which can affect drug clearance), or older age. Using Lyrica together with other medicines that can lower blood pressure or affect fluid retention may also increase the chance of problematic cardiovascular effects.
What should you do if symptoms start?
If you develop severe symptoms like chest pain, fainting, or trouble breathing, seek emergency care. For less urgent but concerning symptoms (for example, noticeable swelling or rapid weight gain), contact the prescribing clinician as soon as possible. Do not stop Lyrica abruptly without medical guidance, since it can worsen underlying pain or other conditions for which it was prescribed.
How to reduce risk while taking Lyrica
Clinicians often manage risk by:
- Starting with the lowest effective dose and adjusting slowly
- Monitoring for swelling, weight changes, and blood pressure effects
- Reviewing kidney function (pregabalin is cleared through the kidneys)
- Reassessing the plan if heart-failure-like symptoms appear
If you share your dose, age, kidney history, and any heart conditions you have, I can help you think through what symptoms to prioritize and what questions to ask your prescriber.
