Pregabalin (Lyrica) and gabapentin (Neurontin and others) are drugs used to prevent seizures and to treat nerve pain associated with various conditions (shingles, diabetic neuropathy). Lyrica and gabapentin both cause similar side effects, including tremors, blurred or double vision, memory or concentration problems, dizziness, and drowsiness. Use of gabapentin for central neuropathic pain is therefore off-label. However, gabapentin is recommended by NICE as a first-line treatment option for adults with all types of neuropathic pain (except trigeminal neuralgia). Interactions. There are no clinically relevant pharmacokinetic interactions between gabapentin and pregabalin. Gabapentin and pregabalin belong to the same class of medicines — gabapetinoids. So, there are a lot of similarities between them. They both work in a similar way, although Lyrica and gabapentin are two prescription drugs used to treat nerve pain and focal onset seizures. Find out how they’re alike and different. If you’re not in the same household, stay on Gabapentin is an anticonvulsant with pain-relieving effects that may be used to treat certain seizure disorders or relieve nerve pain. Common side effects include dizziness or drowsiness and it may more. Pregabalin is used in the treatment of nerve pain and also to prevent seizures. Gabapentin and pregabalin are antiepileptic drugs commonly used for neuropathic pain management and pain reduction in adults. Both medications are classified as antiepileptic medications, but they have differences in pharmacokinetics, safety profile, and clinical applications. Lyrica (pregabalin) is both chemically and structurally similar to gabapentin. It does however, have a unique way of being absorbed and has much better bioavailability than gabapentin does. Lyrica is almost totally absorbed (~90%) very quickly after taking by mouth. Gabapentin is not the same as pregabalin, even though they both belong to the same class of medicine, called gabapentinoids, and work similarly. Lyrica and Lyrica CR are the only brands of pregabalin. Neurontin is a brand name for gabapentin. Other brands of gabapentin include Gralise and Horizant. There are numerous reasons as to why gabapentin is currently, and has historically, been more popular than pregabalin, including: (1) its release ~11 years prior to that of pregabalin; (2) its status as the only “gabapentinoid” medication available (for ~11 years prior to gabapentin); (3) its ability to treat the same medical conditions as Lyrica and gabapentin generally aren't used together due to the similarity in how they work.Nevertheless, preliminary studies evaluating the combined use of low doses of both drugs have found that there may be improved tolerability and pain-relieving effects when compared to the use of a single agent alone. Gabapentin and pregabalin are similar drugs but differ in several distinct ways. The main differences are their indications—specific uses that the Food and Drug Administration (FDA) has approved them to treat—and their dosages. If your physician prescribes pregabalin, it will cost you more than the same dose-equivalent script for gabapentin. How much more you pay depends on your insurance. Most insurers place pregabalin in a higher tier or cost bracket than gabapentin, so you end up paying more for it. Given the added expense, is pregabalin worth it? Pregabalin and gabapentin can both provide relief from pain and be effective ways to manage seizure disorders. However, it’s important to consider the differences between them. Pregabalin is more rapidly absorbed compared to gabapentin, which has a slower absorption rate. Gabapentin and Lyrica (pregabalin) are two common drugs prescribed to treat several different medical conditions, including nerve pain. In 2019 alone, more than 47 million gabapentin prescriptions and more than nine million pregabalin prescriptions were filled in the U.S. But for all the similarities between the drugs, you should know some key differences if you take one of these [] One of the primary distinctions between gabapentin and pregabalin is that the Food and Drug Administration has approved both drugs for some of the same uses but also different ones. In the chart below, we have given the indications for which the FDA approves pregabalin and gabapentin [1]: While gabapentin (Neurontin) and pregabalin (Lyrica) share many similarities, there are a few things that set them apart. We’ll highlight seven key differences between these medications below. 1. Pregabalin is FDA approved for more uses than gabapentin, but both are often used off-label. Gabapentin contains the active ingredient gabapentin. Both Lyrica and gabapentin belong to a class of drugs known as anticonvulsants. The Food and Drug Administration (FDA) has approved Gabapentin and pregabalin are both used to treat partial-onset seizures and nerve pain from shingles (postherpetic neuralgia). Additionally, gabapentin and pregabalin are used off-label to treat a variety of mental health and pain disorders. Lyrica is the brand name for the drug pregabalin, and gabapentin is the name of the medication that is used in drugs such as Neurontin, Gralise, and Horizant. All of these drugs are prescribed as anticonvulsant or antiepileptic medications. Gabapentin is indicated as adjunct therapy for partial seizures and postherpetic neuralgia. 4 Pregabalin is indicated for the same uses as gabapentin, plus the management of fibromyalgia and neuropathic pain associated with diabetes, specifically diabetic neuropathy. 5
