Is 75mg likely to contribute to weight gain?
The short version: yes, weight gain is a real and documented side effect of pregabalin, but the records here tie it to higher doses, not to 75 mg.
The clearest signal comes from the epilepsy trials, where pregabalin at 150 to 600 mg a day was tested against placebo and weight gain showed up among the side effects [3]. That is a dose range well above yours. The 75 mg starting dose in the diabetic nerve pain trial produced only mild, self-limiting side effects, and weight gain was listed as an outcome but not flagged as a problem at that level [1][2]. The fibromyalgia trials ran 150 to 600 mg a day and reported a "generally favorable" safety profile without singling out weight [4].
What the records do not give you is a clean number for weight gain at 75 mg specifically. No trial here isolates that dose and tracks pounds over months. The mechanism is plausible: pregabalin is a calcium channel drug that affects appetite and fluid retention, and both can move the scale. But plausible is not measured.
| Dose range | Weight gain signal in these records |
|---|---|
| 75 mg/day | Not flagged; mild side effects only [1] |
| 150–600 mg/day | Listed among side effects [3] |
| 150–600 mg/day (fibromyalgia) | "Generally favorable," not highlighted [4] |
My call: at 75 mg, weight gain is possible but the evidence here does not show it as a likely or prominent effect, and the risk rises with dose. Confidence: low, because no record tracks weight at your exact dose over time.

Evaluation of efficacy and safety of gabapentin, duloxetine, and pregabalin in patients with painful diabetic peripheral neuropathy
In a 12-week randomized open-label trial, gabapentin, duloxetine, and pregabalin each significantly reduced pain and sleep interference in painful diabetic peripheral neuropathy without significant between-group differences; pregabalin gave faster early relief and adverse reacti…

Comparative Study of Gabapentin Versus Pregabalin in Improving Sensory Nerve Function and Glycemic Variability in Type 2 Diabetes Mellitus.
In adults with diabetic peripheral neuropathy, 12-week treatment with gabapentin or pregabalin was associated with significant within-group improvements from baseline; no serious adverse effects occurred, and the authors concluded that calcium channel modulators offer functional…
