Question explored with the scientific record
Is Pregabalin addicitive
Yes, pregabalin is addictive. The evidence shows it causes a diagnosable use disorder, is misused recreationally, and produces withdrawal symptoms.
The strongest evidence comes from case reports and a systematic review. A 2024 case report describes a patient who escalated to 3000 mg/day and met criteria for pregabalin use disorder [1]. A 2023 report of two migrants in a detention center diagnosed them with moderate pregabalin use disorder, noting tolerance, craving, and withdrawal [2]. That same paper cites a 2021 systematic review that found 19 cases of pregabalin abuse, with 16 showing tolerance and withdrawal [2].
A 2020 review in the British Journal of Pain confirms that pregabalin has more abuse potential than gabapentin, and both were reclassified as class C controlled substances in the UK in 2019 [3]. A 2020 Australian poison center study of 488 pregabalin overdose presentations found that 121 (25%) were recreational exposures, and 107 patients had a history of substance use disorder [4]. A 2025 Libyan cross-sectional study of 80 pregabalin users found that 57.5% reported non-medical use [5].
The mechanism is straightforward. Pregabalin binds to the alpha-2-delta subunit of voltage-gated calcium channels, reducing neurotransmitter release. This produces euphoria, sedation, and a calming effect that people with a history of substance abuse find rewarding. Withdrawal symptoms include anxiety, insomnia, agitation, and in severe cases, seizures [2][3].
The risk is not equal for everyone. People with a history of substance use disorder, especially opioid or benzodiazepine dependence, are at much higher risk of misusing pregabalin [2][3][4]. But the drug can produce dependence even in people who start it for a legitimate medical reason like nerve pain or fibromyalgia.
My call: pregabalin is addictive, with documented cases of use disorder, recreational misuse, and withdrawal. The risk is highest in people with a history of substance abuse, but anyone taking it long-term can develop physical dependence. Confidence: high.
