How should pregabalin be tapered to avoid severe withdrawal symptoms?

The short version: no controlled taper trial exists in these records, but the case evidence shows that abrupt cessation can trigger seizures and that a slow, daily dose reduction resolves withdrawal.

The retrieved evidence contains no randomized taper trial, no guideline from a major body, and no head-to-head comparison of taper speeds. What it does contain is a 2026 case report of a 24-year-old man who had been taking 4,200 mg/day of pregabalin (14 times the typical maximum dose) and had a generalized tonic-clonic seizure three days after stopping abruptly [1]. All tests were normal, and the seizure did not recur once he was restarted on 300 mg/day and tapered by 25 mg/day [1]. A 2024 commentary advises that doses should be tapered rather than stopped suddenly, even in patients on standard doses [2].

The practical lesson from these records is that the taper should be gradual and individualized. The case that worked used a 25 mg/day reduction from a starting dose of 300 mg/day [1]. For someone on a lower dose, a slower reduction—cutting by 10–15% of the current dose every 5–7 days—is the common clinical approach, though no study here tests that rate. The key principle is that the central nervous system adapts to pregabalin’s presence, and removing it too quickly can cause rebound anxiety, insomnia, agitation, and, in extreme cases, seizures [1, 2].

My call: the evidence supports a slow, daily or every-other-day dose reduction, but no specific schedule has been tested in a controlled trial. The safest approach is to work with a clinician who will adjust the taper to your symptoms. Confidence: moderate—the principle is sound, but the optimal rate is not established in these records.
