Is Pregabalin a Painkiller?

Pain management is a challenging and complex process involving identifying the source of pain—physical, psychological, or both—and treating it accordingly. In recent years, Pregabalin has become a popular option for those dealing with chronic and acute pain. But what exactly is Pregabalin, and how effective is it as a painkiller? Let’s take a look.

What is Pregabalin?

Pregabalin is an anti-epileptic medication, also known as an anticonvulsant. It is most commonly prescribed to treat neuropathic pain and epilepsy. However, it has also been used off-label to treat other types of chronic pain. Scientists believe that Pregabalin calms overactive nerves in the brain that are responsible for sending out signals of pain throughout the body.

How Does Pregabalin Work? 

Pregabalin works by binding to voltage-activated calcium channels in the brain and central nervous system, reducing the release of certain neurotransmitters like glutamate, norepinephrine, and serotonin.

This reduces pain signals sent to the brain, which helps people with neuropathic pain find relief. It also decreases anxiety by dampening fear responses in the brain. 

Pregabalin is similar to gabapentin (Neurontin), another anticonvulsant drug used to treat nerve pain and epilepsy. Both drugs bind to voltage-activated calcium channels, but Pregabalin binds more tightly than gabapentin. This makes Pregabalin more effective at treating neuropathic pain because it significantly impacts neurotransmitters like glutamate. As a result, Pregabalin also has fewer side effects than gabapentin since it does not need to be taken as frequently or in large doses for it to be effective. 

In addition to treating neuropathic pain and anxiety, Pregabalin can also be used as an adjunct treatment for partial-onset seizures in adults with epilepsy. When taken along with other medications for epilepsy, Pregabalin can help reduce seizure frequency by blocking calcium channels that are involved in sending electrical signals throughout the central nervous system. This helps keep seizure activity under control so that people with epilepsy can manage their condition effectively. 

How Effective Is Pregabalin as a Painkiller?

Pregabalin has proven to be very effective in treating certain types of chronic and acute pain. Studies conducted on patients suffering from neuropathic pain have indicated that Pregabalin significantly reduced their symptoms compared to placebo treatments. Additionally, some research suggests that Pregabalin may be more effective than traditional opioid medications at managing certain types of pain, such as diabetic peripheral neuropathy or fibromyalgia. However, there are some potential side effects associated with Pregabalin use, such as dizziness, fatigue, and weight gain, which may limit its effectiveness for some people.


Overall, Pregabalin can be an effective treatment for certain types of chronic and acute pain when prescribed appropriately by a doctor or healthcare provider. It has been shown to reduce symptoms more effectively than placebo treatments in studies on patients with neuropathic pain and could potentially be more effective than opioids in some cases. However, it is essential to note the potential side effects associated with Pregabalin so you can make an informed decision about whether this medication is proper for you. Ultimately, your doctor will know best when it comes to managing your specific type of pain, so always consult with them before starting any new treatment plan.
