What happens when you take alcohol with pregabalin?
Pregabalin, sold as Lyrica and Lyrica CR, is used for nerve pain, fibromyalgia, and certain seizures, and off-label for anxiety. Alcohol is a central nervous system depressant, and so is pregabalin. When you combine them, their depressant effects add together. Here is the chain of events:
- Both reach the brain at once. Alcohol and pregabalin each dial down activity in the central nervous system. Taken together, the slowdown is greater than either one alone.
- Sedation and dizziness climb. Pregabalin already causes drowsiness and dizziness in a large share of people. Alcohol amplifies both, leaving you more sedated and unsteady than you would expect from your usual drink.
- Coordination and judgment slip. Blurred vision, slowed reaction time, and unsteadiness set in, raising the risk of falls and making driving genuinely unsafe.
- Breathing can slow. At the serious end, the combined depressant effect can suppress the drive to breathe. The FDA and MHRA both warn this can become life-threatening, especially when other sedatives are in the mix.
In December 2019 the FDA issued a Drug Safety Communication warning that pregabalin (and gabapentin) can cause serious, life-threatening, or fatal respiratory depression when combined with CNS depressants such as alcohol and opioids. The UK's MHRA issued a parallel warning the same year, and Lyrica's labeling was updated to reflect the risk.
Why is this important?
This is not a theoretical concern. The regulators' warnings are built on real reports of severe respiratory depression, and a pharmacovigilance review of the cases behind the FDA action found that the overwhelming majority of people who experienced respiratory depression either had a respiratory risk factor or were also taking another CNS depressant. Alcohol is exactly that kind of added depressant.
The people at highest risk for slowed breathing from this combination are:
- Older adults, whose respiratory reserve is lower and who often take several sedating medicines
- People with chronic lung disease such as COPD or severe asthma
- People with treated or untreated sleep apnea
- Anyone also taking opioids, benzodiazepines, muscle relaxants, sedating antihistamines, or sleep aids
- People with reduced kidney function, because pregabalin is cleared by the kidneys and can build up when clearance is impaired
- People with a history of substance misuse
Pregabalin also carries real misuse and dependence potential — it is a controlled substance in both the US and the UK. People who misuse it recreationally often combine it with alcohol and opioids, and those combinations account for a meaningful share of pregabalin-related deaths. Even short of that, the everyday combination of alcohol and pregabalin produces marked impairment: falls (particularly in older adults) and significant driving impairment.
What should you do?
Before any change: Talk to your doctor or pharmacist before drinking any alcohol on pregabalin. Be honest about how much you drink, any lung or kidney problems, any sleep apnea, and every other sedating medicine you take — including opioids, benzodiazepines, sleep aids, and cannabis. If you also take an opioid, ask whether take-home naloxone would be sensible as a rescue medicine.
Every day on pregabalin: The safest course is to avoid alcohol entirely, and that is the firm recommendation if you are older, have lung disease or sleep apnea, have reduced kidney function, or take any other depressant. Never stack pregabalin and alcohol with a second sedative. Be especially careful during the first weeks of treatment and any dose increase, before your body adjusts to the sedation.
After drinking, or if you slip: Do not drive or operate machinery — wait until you are fully clear-headed, which takes longer than usual on pregabalin. Have someone with you. Watch for warning signs that need immediate emergency care: severe drowsiness, slow or shallow breathing, blue lips or fingertips, confusion, or unresponsiveness. If any of these appear, call emergency services.
Which specific products are affected?
The warning applies to all pregabalin products: Lyrica capsules and oral solution, Lyrica CR (controlled-release) tablets, and all generic pregabalin. The closely related drug gabapentin (Neurontin, Gralise, Horizant) carries an essentially identical FDA warning.
"Alcohol" means any ethanol-containing drink — beer, wine, hard seltzer, spirits, fortified wines, and cocktails. Other CNS depressants that compound the risk include opioids (such as oxycodone, hydrocodone, morphine, fentanyl, tramadol, codeine, methadone), benzodiazepines (such as alprazolam, lorazepam, clonazepam, diazepam), Z-drugs (such as zolpidem, eszopiclone), muscle relaxants (such as cyclobenzaprine, baclofen, tizanidine), sedating antihistamines (such as diphenhydramine, hydroxyzine), and cannabis. Combining three or more depressants — for example pregabalin plus an opioid plus alcohol — is particularly dangerous.
The science behind it
The core evidence comes from regulators acting on real-world safety reports:
- FDA Drug Safety Communication (December 19, 2019) required new warnings that gabapentin and pregabalin can cause serious breathing problems, with the risk highest in people using CNS depressants such as opioids, older adults, and those with underlying lung dysfunction. (fda.gov)
- MHRA Drug Safety Update — pregabalin (Lyrica): reports of severe respiratory depression advises avoiding alcohol and notes that CNS depressants have been associated with respiratory failure, coma, and deaths, with higher risk in older people and those with respiratory or kidney impairment. (gov.uk)
- A pharmacovigilance review of the respiratory concerns behind the 2019 FDA warning reported that the great majority of the respiratory-depression cases (roughly 9 in 10 of the 49 reviewed) involved either a respiratory risk factor or concurrent CNS depressant use — underscoring that the danger concentrates in exactly the situations alcohol creates or worsens (PMC7919607).
Taken together, these sources establish that the alcohol–pregabalin interaction is real and can be serious, while also showing that the worst outcomes cluster in identifiable higher-risk groups rather than affecting everyone equally.
Frequently Asked Questions
Is one drink on pregabalin dangerous?
For a healthy person on a low dose, a single drink is most likely to cause extra drowsiness and unsteadiness rather than a breathing emergency. But the safest answer is to avoid alcohol, and the danger rises sharply if you are older, take other sedatives, or have lung, kidney, or sleep-apnea issues. Check with your doctor or pharmacist about your own situation.
How long after taking pregabalin do I need to wait before drinking?
There is no proven "safe gap" that removes the interaction, because pregabalin stays active in your system across the day and you typically take it on an ongoing schedule. Rather than timing drinks around doses, the practical advice is to avoid alcohol while you are on pregabalin and discuss any exceptions with your prescriber.
What are the warning signs I should worry about?
Severe drowsiness, slow or shallow breathing, blue lips or fingertips, confusion, or unresponsiveness. Any of these means you need emergency medical care right away.
Does this apply to gabapentin too?
Yes. Gabapentin (Neurontin, Gralise, Horizant) carries an essentially identical FDA warning about serious breathing problems when combined with CNS depressants such as alcohol.
I take pregabalin with an opioid. What should I do?
This is a higher-risk combination, and adding alcohol makes it more dangerous still. Avoid alcohol, and ask your prescriber whether take-home naloxone is appropriate as a rescue medicine in case of an emergency.
Why is pregabalin riskier for people with kidney problems?
Pregabalin is cleared by the kidneys. If your kidney function is reduced, the drug can build up to higher levels, which increases sedation and the risk of slowed breathing — so the threshold for any alcohol is even lower. Review this with your doctor.
Key takeaways
- Pregabalin and alcohol are both CNS depressants; together they add up to more sedation, dizziness, and impaired coordination, and can slow breathing.
- The FDA (2019) and MHRA both warn that pregabalin plus CNS depressants such as alcohol can cause severe, sometimes fatal, respiratory depression.
- Risk is highest in older adults, people with lung disease or sleep apnea, those with reduced kidney function, and anyone also taking opioids or other sedatives.
- The safe default is to avoid alcohol on pregabalin, and to never stack multiple depressants.
- Know the emergency signs — severe drowsiness, slow or shallow breathing, blue lips, confusion, unresponsiveness — and call for help immediately.
- Review your alcohol use, other medicines, and any need for rescue medication with your doctor or pharmacist.
