Gabapentin vs Lyrica: Key Differences, Effectiveness & Which Is Better?

Millions of people worldwide are bearing different types of pain due to damaged nerve cells in the brain. Neuropathic pain or nerve pain is unbearable and significantly impacts the quality of life. Two common medications, Gabapentin and Lyrica, are prescribed for those struggling to manage this type of pain. Both are members of the same drug class known as gabapentinoids, but differ in several key aspects, like effectiveness, dosages, and side effects. This article is all about Gabapentin Vs Lyrica, offering the information needed to make an informed decision in consultation with your healthcare provider.

Difference between Gabapentin and Lyrica

What are Gabapentin and Lyrica?

Gabapentin

Gabapentin is an FDA-approved anticonvulsant medication, marketed under the brand name Neurontin. It is an effective treatment for the conditions of postherpetic neuralgia, diabetic neuropathy, restless leg syndrome, partial seizures, and fibromyalgia. This drug works by altering pain signals in the brain and the central nervous system. 

Lyrica

Alternately, Lyrica is the brand name for Pregabalin, and is available in an extended-release version known as Lyrica CR. It is a medication used for diabetic nerve pain, fibromyalgia, epilepsy, nerve pain after shingles, and spinal cord injury nerve pain. In some cases, this drug is prescribed for generalized anxiety disorder and works by calming nerve activity in the brain to reduce pain. 

Similarities in Gabapentin and Lyrica

Though Lyrica and Gabapentin belong to the same drug class, some similarities exist. Both work by binding to voltage-gated calcium channels in the central nervous system to help reduce pain and prevent seizures.

The same side effects have been reported with both medications, such as fatigue, dizziness, and difficulty concentrating. Both drugs may cause withdrawal symptoms, especially with other sedatives, alcohol, or medications that affect the central nervous system.

Both Gabapentin and Lyrica are generally taken orally in the form of capsules or tablets. Primarily, they are initiated at low doses to minimize the side effects. Due to a higher dose or overdose, both drugs may lead to withdrawal symptoms, including anxiety, insomnia, nausea, and severe seizures.

Key Differences between Gabapentin & Lyrica

Although Gabapentin and Lyrica belong to the same drug family and are believed to work in similar ways, they have some differences. These differences affect your treatment experience. Let’s discuss the differences which are associated with the drugs.

• Compared to Gabapentin vs Lyrica, a major difference is that the Drug Enforcement Administration (DEA) has classified Lyrica as a Schedule V controlled substance due to the potential for abuse and dependence. In contrast, Gabapentin is not currently scheduled as a controlled substance. Hence, it indicates that Gabapentin has a lower risk of misuse.
• Lyrica absorbs faster into the bloodstream than Gabapentin. This means it starts working quicker within an hour. So, most of the time, Lyrica is prescribed when a quicker therapeutic effect is needed. On the other hand, Gabapentin works slowly and takes longer for effective results, requiring consistent dosing to maintain therapeutic levels.
• Generally, Gabapentin needs to be taken multiple times a day due to its slower absorption. As Lyrica, especially the extended-release version, is taken once or twice daily. Gabapentin’s peak time is between 3-4 hours and lasts for about 5-7 hours. Meanwhile, Lyrica’s peak time is about 1-1.5 hours, and its effects last between 8 to 12 hours.
• Lyrica is available in the following doses and dosage forms.
  • Capsules: 25 mg, 50 mg, 75 mg, 100 mg, 150 mg, 200 mg, 225 mg, 300 mg
  • Oral Liquid: 20 mg/ml
  • Extended-Release Tablets: 82.5 mg, 165 mg, 330 mg
• Comparably, Gabapentin is also available in different doses and dosage forms. But the extended-release tablet form may be given only once daily.
  • Capsules: 100 mg, 300 mg, 400 mg
  • Oral Solution: 250 mg/5 ml
  • Tablets: 100 mg, 300 mg, 400 mg, 600 mg, 800 mg
  • Extended-release Tablets: 300 mg, 600 mg

Which is better between Gabapentin and Lyrica

Both Gabapentin and Lyrica are effective for nerve pain. But choosing which is better is a complex decision because it depends on your overall health condition, medical history, and treatment goals. Many researchers reported, if you need stronger pain relief, have fibromyalgia, and require a faster-acting medication, Lyrica is better. But it has a higher risk of dependence. Alternately, Gabapentin is the right choice if you prefer a non-controlled medication, but it requires higher doses for the same effect. It is the best decision to seek medical advice from a physician to determine which drug best fits your needs.

Gabapentin Vs Lyrica Side Effects

Both Gabapentin and Lyrica are prescribed to treat nerve pain as well as partial-onset seizures that occur after shingles. So, most of the time, they have similar side effects. But some studies specify that Lyrica has a comparatively lower risk of adverse effects. Some of the effects are given in the table that can happen for both Lyrica and Gabapentin.

Comparison of Their Clinical Uses

Both medications are widely prescribed to help manage nerve pain, anxiety, seizures, and back pain. Here, we discuss some important clinical uses of both drugs and their benefits.

For Neuropathy

As we compared Gabapentin vs Lyrica, both are the first-line treatments for neuropathy. But Lyrica has consistently expressed higher efficacy compared to Gabapentin in managing neuropathy pain. After many studies, it is concluded that Lyrica continues to improve pain relief up to 450 mg/day, while Gabapentin is better at 3600 mg/day. So, Lyrica is more potent and fast-acting at lower doses, where Gabapentin is also effective but requires higher doses to reach the same levels of pain relief. It is advisable, always consult with a medical professional to choose the best option for your needs for pain relief.

For Anxiety

For anxiety treatment, both Gabapentin and Lyrica are prescribed. But here is one thing to remember: Lyrica is officially approved for anxiety disorders, particularly generalized anxiety disorder (GAD), whereas Gabapentin is not FDA-approved but used to treat off-label anxiety. Both medications work by improving the activity of neurotransmitters to reduce lower anxiety symptoms. Lyrica is more preferable than Gabapentin for its effectiveness in managing both short-term and long-term anxiety symptoms. If stopped suddenly from both medications, they show withdrawal symptoms. So, always start or stop any medications under close medical supervision.

For Seizure

It is approved, and many doctors recommend Gabapentin, as well as Lyrica, to manage partial seizures. It is a fact that Lyrica requires lower doses for similar effects, so it is more potent and works faster. Gabapentin pills are also effective, but need higher doses and take a long time to achieve full effectiveness. In severe cases of patients, physicians may recommend Lyrica for fast-acting relief. Always visit a skilled health expert to choose whether Gabapentin or Lyrica is the best treatment for your condition.

Withdrawal Symptoms

Withdrawal may occur when an individual suddenly stops using the drug or reduces the drug dosage without a doctor’s approval. On the other hand, if one has misused either of these drugs, one may face a high risk of complicated withdrawals that are not well-controlled. In this situation, immediately seek emergency medical help to recover. Here, we provide some withdrawal symptoms that are related to each of the drugs.

Gabapentin Withdrawal Symptoms

• Muscle Pain
• Sweating
• Anxiety
• Nausea
• Insomnia
• Increased Heart Rate

Lyrica Withdrawal Symptoms

• Anxiety
• Headache
• Sleep Problem
• Diarrhea

Frequently Asked Questions (FAQs)

Can I Take Gabapentin and Lyrica Together?

Most people avoid using Pregabalin and Gabapentin concurrently, as both work similarly by affecting voltage-gated calcium channels in the nervous system. As they believed in working uniformly, this led to duplication, which enhanced the adverse effects like dizziness, confusion, and drowsiness. If you use Gabapentin, at that time, the doctor thinks to switch you to Lyrica or vice versa. But rarely, in treatment-resistant cases of severe neuropathic pain, a specialist may try low doses of both. Hence, before using the medication, first visit with a primary care provider.

Are Gabapentin and Lyrica the Same?

Lyrica and Gabapentin are related, but not the same. They both are known to work on calcium channels in the brain, but to date, experts are suspicious of how these drugs perform. Because they are structurally similar to the gamma-aminobutyric acid (GABA) neurotransmitter, however, they don’t act on the GABA receptors. Some research indicates that, basically, Lyrica is the higher version of Gabapentin with strong effectiveness.

Can I Use Lyrica or Gabapentin During Pregnancy?

Neither Lyrica nor Gabapentin is considered for use during pregnancy. If you are using it, it requires awareness and can only be done under the close supervision of a skilled health expert. Using this drug during pregnancy delays the bone development of the fetus. Also increased the risk of birth defects and growth restriction. So, consult your physician before starting or continuing either drug while pregnant or planning pregnancy.

Conclusion

For the effective treatment of nerve pain and seizure, Gabapentin and Lyrica are the best options. Lyrica’s faster absorption, onset of action, and greater potency make it more popular for many patients. When considering your treatment option, it is advisable
