⚠ Medical warning

Don’t stop gabapentin suddenly. The FDA label warns abrupt or rapid discontinuation may increase the risk of seizures, and withdrawal symptoms and suicidal thoughts have been reported after stopping. Talk to your prescriber about a gradual taper. Call 911 for a seizure, and call or text 988 for suicidal thoughts.

Quick answer

The FDA label says gabapentin withdrawal symptoms may occur shortly after stopping, usually within 48 hours. Reported symptoms include anxiety, insomnia, nausea, pain, sweating, tremor, headache, dizziness and malaise, and more serious ones like seizures, depression, suicidal thoughts, confusion and psychotic symptoms. Abrupt or rapid stops may increase seizure risk. The Gralise label says to taper over at least 1 week; your prescriber may go slower.

Symptoms, phase by phase

The gabapentin label says withdrawal symptoms have been seen in some patients after both short-term and long-term treatment, usually within 48 hours. Postmarketing reports include seizures, depression, suicidal ideation and behavior, agitation, confusion, disorientation, psychotic symptoms, anxiety, insomnia, nausea, pain, sweating, tremor, headache, dizziness and malaise. The label doesn’t say how long withdrawal lasts, and we haven’t found a reliable primary source that does, so we don’t give a firm end date.

Onset: Usually within 48 hours of stopping

Anxiety, agitation
Insomnia
Sweating
Nausea
Pain

Acute withdrawal: The following days (duration not well defined in the label)

What makes withdrawal longer or shorter

Speed of stopping. Abrupt or rapid stops carry more risk, including seizures.
Why you take it. If you take it for epilepsy, talk to your neurologist before any change.
Dose and duration. Higher doses and longer use may mean more dependence.
Other sedatives. Opioids, alcohol and benzos add risk; the label warns of breathing problems with other CNS depressants.

When to see a doctor or get help now

Before stopping or reducing gabapentin.
Call 911 for a seizure, confusion or hallucinations.
Call or text 988 for suicidal thoughts.
If you’ve been taking non-prescribed gabapentin, especially with opioids, get medical advice.
