Pregabalin: uses, dosing, side effects & brands

Lyrica (Pregabalin) is a medication used to treat Fibromyalgia, Seizures, Spinal Cord Injuries, Postherpetic Neuralgia.

The label states there are no adequate and well-controlled studies of pregabalin in pregnant women, so its risk in human pregnancy is not established. In animal reproduction studies, pregabalin caused developmental toxicity (skeletal malformations, retarded ossification, decreased fetal body weight, and reduced offspring growth/survival) at exposures well above the human dose. The label advises that pregnant women be told of the potential risk to a fetus, and points to a pregnancy exposure registry (the North American Antiepileptic Drug Pregnancy Registry, 1-888-233-2334) that patients can enroll in. Anyone who is pregnant or planning pregnancy should discuss it with their prescriber rather than starting or stopping the drug on their own. This is what pregabalin's FDA label says; whether to use it in pregnancy is your prescriber's decision.

The label reports weight gain as a genuine adverse reaction — it is one of the most common adverse reactions and has its own Warnings and Precautions section (Weight Gain), with rates that rose with dose. The gain was generally not associated with clinically important changes in blood pressure in short trials. Any weight change should be discussed with a prescriber.

The label addresses ethanol under Drug Interactions. When pregabalin was co-administered with ethanol (as well as oxycodone or lorazepam), additive effects on cognitive and gross motor functioning were seen, though no pharmacokinetic interaction and no clinically important effects on respiration were observed in those studies. Pregabalin is a CNS-active drug, and the Warnings section separately notes respiratory depression can occur when it is used with other CNS depressants. Combining pregabalin with alcohol can therefore compound impairment of thinking and coordination. This is what pregabalin's FDA label says; alcohol advice depends on your dose and health, so confirm with your pharmacist.

The label describes physical dependence and a discontinuation reaction. Following abrupt or rapid discontinuation of pregabalin, patients reported insomnia, nausea, headache, diarrhea, anxiety, and hyperhidrosis — the label lists these together in its discontinuation warning, consistent with physical dependence. In patients treated for seizures, rapid discontinuation may increase seizure frequency. To avoid this, the label directs that pregabalin be tapered gradually over a minimum of 1 week under prescriber management rather than stopped abruptly. Pregabalin is a Schedule V controlled substance, but there is no boxed warning. Do not stop pregabalin on your own — any change is a prescriber-managed decision.

The elimination half-life of pregabalin is about 6.3 hours (mean, in adults with normal kidney function) — that is how long the body takes to clear half of a dose. Pregabalin has no active metabolite of concern — it is excreted almost entirely unchanged in the urine and barely metabolized — but its half-life is prolonged in people with reduced kidney function, because elimination is nearly proportional to creatinine clearance. Half-life is not the same as how long a drug test can detect the drug, and it varies with age, kidney and liver function.

It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run pregabalin against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.

We track 3 pregabalin-containing products in the U.S.: Lyrica, Lyrica CR and Pregabalin. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.

Across the brands we track, pregabalin is currently marketed as capsule, solution and tablet, extended release, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.

Yes. Our catalog lists 1 generic pregabalin product alongside the brand versions. A generic has the same active ingredient and must meet the FDA's bioequivalence standard; it usually costs less. Ask your pharmacist which one your plan covers.

The FDA's Enforcement database lists 1 recall record whose product description mentions pregabalin. The most recent: Pregabalin Capsules 50mg (May 16, 2024). A recall applies to specific lots, not to the drug as a whole — check the record for the affected lot numbers.

Pregabalin can ease nerve pain relatively quickly for some people — sometimes within the first week — but the dose is usually increased gradually, so the full benefit may take a few weeks to reach. Do not stop it abruptly.

Alcohol: the FDA label flags alcohol as something to be careful with — see the alcohol section above for what it actually says. This is what the FDA label and our cited sources say — it is not a complete list. Your pharmacist can check your own combination.

Yes. Pregabalin is a federal DEA Schedule V controlled substance — the lowest-risk controlled schedule — because it has a potential for misuse and dependence. It is a gabapentinoid, not an opioid; do not stop it abruptly, as withdrawal can occur.

The most common side effects of Lyrica (pregabalin) are dizziness and drowsiness (somnolence) — in FDA trials, dizziness affected about 30% of adults and somnolence about 23%, versus roughly 8% each on placebo. Other frequent, usually mild effects from the label and MedlinePlus include dry mouth, swelling (edema) of the hands, feet, or ankles, blurred vision, weight gain, increased appetite, constipation, headache, trouble concentrating or 'foggy' thinking, and problems with balance or coordination. The dizziness and sleepiness are often worst when you start Lyrica or after a dose increase and tend to ease as your body adjusts, which is why prescribers usually start low and titrate up. This is not a complete list — check your medication guide and pharmacist for the full one.

Get emergency help right away for serious breathing problems. The FDA label warns Lyrica can cause 'serious, life-threatening, or fatal respiratory depression,' especially when combined with opioids or other CNS depressants (like benzodiazepines or alcohol) or in people with underlying lung disease (COPD) and the elderly — red flags are shortness of breath, wheezing, difficulty breathing, and bluish-tinged skin, lips, or fingernails. Also seek emergency care for signs of a severe allergic reaction (angioedema): MedlinePlus lists 'swelling of the eyes, face, throat, mouth, lips, gums, tongue, head or neck,' plus hives, blisters, or trouble swallowing/breathing — the label says to stop Lyrica immediately if these occur. Call your doctor urgently for unexplained muscle pain, tenderness, or weakness (especially with fever), chest pain, or confusion and extreme sleepiness. Because Lyrica is an antiepileptic drug, the label also warns it can increase suicidal thoughts or behavior; contact a doctor promptly for new or worsening depression, anxiety, panic, agitation, or thoughts of self-harm (call or text 988 in the US for the Suicide & Crisis Lifeline).

Yes. Lyrica (pregabalin) is a Schedule V (CV) controlled substance in the US because it has a potential for misuse and physical dependence, though lower than for many other scheduled drugs. The FDA label documents that some people — particularly those with a history of substance misuse — can develop dependence, and euphoria ('elevated mood') is a recognized effect. Physical dependence means your body adapts to the medication, so stopping suddenly can trigger withdrawal even when it has been taken exactly as prescribed. Take Lyrica only as directed, and tell your prescriber about any personal or family history of drug or alcohol misuse.

Do not stop Lyrica (pregabalin) abruptly on your own — it must be tapered under your prescriber's guidance. The FDA label directs doctors to 'withdraw LYRICA gradually over a minimum of 1 week.' MedlinePlus warns that stopping suddenly can cause withdrawal symptoms including trouble falling or staying asleep, nausea, diarrhea, headache, and — importantly — seizures. If Lyrica isn't working, is causing side effects, or you want to come off it, talk to your prescriber so they can lower the dose safely on a schedule rather than stopping all at once.

The most common side effects — dizziness and drowsiness — typically begin within the first few days of starting Lyrica (pregabalin) or after a dose increase, because blood levels rise quickly. For most people these early effects ease over days to a couple of weeks as the body adjusts, which is why doctors often start at a low dose and increase gradually. Some effects can persist while you keep taking the drug, such as fluid-related swelling (edema) of the hands and feet, weight gain, and blurred vision, and these are worth reporting to your prescriber if they bother you. Timelines vary by person and dose — the honest answer from the FDA label and MedlinePlus is that early dizziness/sleepiness usually improve, while a few effects may continue and should be managed with your doctor rather than by stopping on your own.
