Pregabalin: A Schedule V Medicine Used Off-Label for Anxiety

What pregabalin is

MedlinePlus places pregabalin in a class of medicines called anticonvulsants. It comes as capsules, a liquid and extended-release tablets. Lyrica and Lyrica CR are the current brand names on DailyMed, and generics are available. The two brands have different approved uses.

What is approved, and what is off-label

The Lyrica label lists nerve pain from diabetic peripheral neuropathy, postherpetic neuralgia (nerve pain after shingles), add-on treatment of partial onset seizures in people 1 month and older, fibromyalgia, and nerve pain from spinal cord injury. Lyrica CR is approved only for the diabetic nerve pain and postherpetic neuralgia, and its label says effectiveness has not been established for fibromyalgia or as an add-on for partial onset seizures.

Use for anxiety is off-label. A 2020 review in Frontiers in Psychiatry says pregabalin is not approved for anxiety in the United States and is prescribed off-label for it. A StatPearls chapter on NCBI Bookshelf lists generalized anxiety disorder and social anxiety disorder among off-label uses, and notes significant controversy about how well it works for off-label uses overall.

The 2020 review also says research on this class of medicines for anxiety disorders is scant, with the strongest evidence being for pregabalin in generalized anxiety disorder. Evidence of that kind does not change its status: the FDA label still does not list anxiety.

How it is thought to work

The label says pregabalin binds strongly to the alpha-2-delta site, a part of voltage-gated calcium channels in the central nervous system, and that its mechanism has not been fully worked out. MedlinePlus describes how it reduces pain signals from damaged nerves. The label does not describe how it would act on anxiety, since that is not an approved use.

What taking it can be like

The label says dizziness and sleepiness generally begin shortly after starting and happen more often at higher amounts. They can affect driving and machinery, so it advises waiting until you know how pregabalin affects you. Weight gain and swelling in the hands or feet can also occur. MedlinePlus lists feeling "high" or elevated mood, trouble concentrating and forgetfulness among its side effects, which are worth reporting honestly.

Side effects and warnings

Pregabalin has no boxed warning on the Lyrica label, but the warnings section includes life-threatening risks.

• Swelling and allergy: swelling of the face, mouth or neck can be life-threatening and affect breathing, and hives, wheezing and shortness of breath have occurred. The label says these signs need emergency help right away. Tell your prescriber if you have had this swelling before or take an ACE inhibitor.
• Suicidal thoughts: antiepileptic medicines, including pregabalin, increase the risk of suicidal thoughts or behavior for any use. Watch for new or worse depression or unusual mood or behavior changes. If you have thoughts of harming yourself, call or text 988, or call 911.
• Breathing: the label links pregabalin to serious, life-threatening or fatal respiratory depression when taken with opioids or other sedating medicines, or in people with breathing problems. Call 911 for trouble breathing, bluish lips or skin, confusion or extreme sleepiness.
• Common effects in adults: dizziness, sleepiness, dry mouth, swelling, blurred vision, weight gain and trouble with concentration or attention.
• Also on the label: caution with swelling in people with serious heart failure or on certain diabetes medicines, muscle problems with raised creatine kinase, lower platelet counts and a heart tracing change called PR interval prolongation. Report muscle pain or weakness, especially with fever, and any vision changes.

Controlled status, misuse and stopping

The label calls pregabalin a Schedule V controlled substance and tells prescribers to evaluate any history of drug misuse and to watch for signs such as dose escalation and drug-seeking. It reports that in a study of people who used sedatives recreationally, pregabalin received ratings for "good drug effect," "high" and "liking" similar to diazepam, and that euphoria was reported in clinical studies. MedlinePlus says it may be habit forming.

Do not stop pregabalin suddenly. The label says abrupt or rapid discontinuation may raise seizure risk and has been followed by insomnia, nausea, headache, anxiety, sweating and diarrhea, and it describes these symptoms as consistent with physical dependence. Suicidal thoughts have also been reported after discontinuation. The label says to reduce it gradually, on your prescriber's plan. If you or your partner are pregnant or planning a pregnancy, or you are breastfeeding, tell your prescriber.

Can pregabalin be managed online in Pennsylvania and New York

As of November 2026, a temporary federal rule (Federal Register, Fourth Temporary Extension) allows DEA-registered practitioners to prescribe Schedule II to V medicines by audio-video telemedicine without a prior in-person evaluation, under set conditions, through December 31, 2026. Rules may change after that date.

That rule describes what is allowed in general. It does not mean any particular clinician prescribes this medicine or that a visit will end in a prescription. Whether it is an option for you is a decision for you and your prescriber. Ask us whether our psychiatrist can help, using our medication inquiry form.
