Can Lyrica (pregabalin) cause memory problems or “brain fog”?
Lyrica (pregabalin) can affect how some people think and feel, and that may include difficulties with concentration and memory. Reports and labeling commonly describe cognitive side effects such as confusion, trouble concentrating, or feeling mentally “foggy,” which can be experienced as short-term memory problems.
What might patients notice in day-to-day life?
People who feel cognitive effects from Lyrica often describe:
- Slower thinking or trouble focusing
- Feeling mentally dulled
- Forgetfulness or difficulty tracking conversations or tasks
These effects are more likely when the dose is higher, treatment is started recently, or another sedating medicine is used.
Why would Lyrica affect memory?
Lyrica works on the nervous system (it changes signaling involved in nerve pain). That same effect can also reduce neuronal activity in ways that lead to sedation or cognitive slowing in some patients, which can show up as impaired attention and memory.
When are memory issues most likely to show up?
Cognitive side effects often show up soon after starting or increasing the dose, then may improve as the body adjusts. If symptoms persist or worsen, it can be a sign the dose is too high for that person or that there’s an interaction with another medication.
What increases the risk?
Memory-related side effects are more likely if you:
- Take a higher dose or recently increased it
- Start Lyrica and have not yet adjusted
- Are older (cognitive sensitivity is higher)
- Use other sedating drugs (for example, opioids or benzodiazepines)
- Have kidney problems (pregabalin is cleared through the kidneys, so accumulation can increase side effects)
What should you do if you notice memory problems?
If you notice new forgetfulness, confusion, or significant difficulty concentrating after starting or raising Lyrica:
- Contact your prescriber promptly.
- Don’t stop abruptly without medical guidance.
- Ask whether your dose should be reduced or whether another medication is a better fit.
If you develop severe confusion, fainting, or dangerous sleepiness, seek urgent medical care.
Does stopping Lyrica improve memory?
In many cases, cognitive symptoms improve after the dose is adjusted or the medication is discontinued, but the timeline depends on the person, the dose, and any other contributing factors.
