Does Pregabalin (Lyrica) cause weight gain?
The honest answer from the FDA-approved label for Pregabalin (Lyrica)— what the trials actually reported, not the “every drug makes you gain weight” folklore.
What the label reports
The label reports weight gain as a genuine adverse reaction — it is one of the most common adverse reactions and has its own Warnings and Precautions section (Weight Gain), with rates that rose with dose. The gain was generally not associated with clinically important changes in blood pressure in short trials. Any weight change should be discussed with a prescriber.
Frequently asked questions
Does Pregabalin cause weight gain?
Yes — the label reports weight gain for Pregabalin (details above). How much varies between people and is not the same for everyone; it is a known, monitored effect, not a reason to stop on your own. Diet, activity, and a conversation with your prescriber about alternatives are the levers.
How much weight can Pregabalin cause?
The label reports what the trials found (above) and does not hand out a single number that applies to everyone — weight change depends on dose, duration, your starting point, and why you are taking the drug. If your weight is changing in a way that bothers you, that is a specific, fixable conversation with your prescriber, not a reason to quit abruptly.
Does the weight come off after stopping Pregabalin?
Often at least partly, when the drug's effect on appetite or metabolism was the cause — but that is individual, and some weight tracks lifestyle rather than the drug. Never stop a medication just to lose weight without talking to the prescriber first; for several of these drugs abrupt stopping has its own risks.

The weight information is what the drug’s FDA-approved label reports from its trials. This is general reference information, not medical advice, and weight change is individual — do not start or stop a medication to change your weight without your prescriber.
