What Should I Know About This Drug Safety Alert
After reviewing case reports and existing medical literature, observational studies, clinical trials, and animal studies, the FDA released a drug safety warning linking gabapentin and pregabalin to serious breathing problems.
Its important to know that this safety alert is not for all users of gabapentin and pregabalin. This drug warning is for people taking gabapentin or pregabalin who also have respiratory risk factors that include:
- Taking gabapentin or pregabalin with a central nerve system depressant or
- Having an existing respiratory condition, such as chronic obstructive pulmonary disease
The FDA also said that elderly users of these medications are at a higher risk of experiencing serious breathing problems.
are sometimes prescribed to treat insomnia, acute stress, anxiety, or muscle spasms. These medications work by slowing brain and nervous system activity. Central nervous system depressants include:
- Benzodiazepines are tranquilizers, such as diazepam , alprazolam , clonazepam , triazolam , estazolam
- Non-benzodiazepine sedative hypnotics help induce sleep, such as zolpidem , eszopiclone , zaleplon
- Barbituates treat seizure or anxiety, such as mephobarbital , phenobarbital , pentobarbital sodium
Rated For Epilepsy Report
Tried Gabapentin for generalized anxiety disorder. Initially the drug seemed like a miracle. I just felt great without side effects, but unfortunately after a few days I developed dizziness, nausea, and increased anxiety. I also didnt feel like my self. I started on 300mg at bedtime and after a few days lowered the dose, but the side effects didnt resolve until I stopped the drug. I will note that I am sensitive to medications and my wife and a friend take Gabapentin with no side effects and excellent results so I wouldnt be afraid to give it a try.

How Should This Medicine Be Used
Gabapentin comes as a capsule, a tablet, an extended-release tablet, and an oral solution to take by mouth. Gabapentin capsules, tablets, and oral solution are usually taken with a full glass of water , with or without food, three times a day.
These medications should be taken at evenly spaced times throughout the day and night no more than 12 hours should pass between doses. The extended-release tablet is taken with food once daily at about 5 PM. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take gabapentin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Gabapentin extended-release tablets cannot be substituted for another type of gabapentin product. Be sure that you receive only the type of gabapentin that was prescribed by your doctor. Ask your pharmacist if you have any questions about the type of gabapentin you were given.
Swallow the extended-release tablets whole do not cut, chew, or crush them.
If your doctor tells you to take one-half of a regular tablet as part of your dose, carefully split the tablet along the score mark. Use the other half-tablet as part of your next dose. Properly dispose of any half-tablets that you have not used within several days of breaking them.
How Does It Work
The studies clearly show that gabapentin works in certain patients. However, it is impossible to tell which patients will benefit and which ones will not. This is why the official recommendation is now to try the medication for a short period of time to determine whether the condition improves or not. The drug works on the central nervous system, essentially stabilizing the brains electrical activity.
In so doing, it affects the signals sent from the nerves to the brain. It is not quite understood how it does this, however, although it seems that there is an increase in GABA production after taking the drug, while at the same time there is a reduction in glutamate release.

Gabapentinoids are FDA-approved to treat a variety of conditions including partial seizures and nerve pain from spinal cord injury, shingles, and diabetes. Other approved uses include fibromyalgia and restless legs syndrome. Gabapentin was first approved in 1993 and pregabalin was first approved in 2004. Gabapentin is marketed under the brand names Neurontin and Gralise, and also as generics. Gabapentin enacarbil is marketed under the brand name Horizant. Pregabalin is marketed under the brand names Lyrica and Lyrica CR, and also as generics. Pregabalin is a Schedule V controlled substance, which means it has a lower potential for abuse among the drugs scheduled by the Drug Enforcement Administration , but may lead to some physical or psychological dependence.

- Confusion or disorientation
- Extreme sleepiness or lethargy
- Slowed, shallow, or difficult breathing

Where Gabapentin And Pregabalin Fit In The Spine Pain Treatment Plan
The FDA has approved gabapentin and pregabalin for several conditions, from seizures and restless leg syndrome to diabetes and fibromyalgia. Although not specifically approved to treat chronic back and neck pain, your doctor may also prescribe these drugs if you have nerve-related spine pain.
Gabapentin and pregabalin, which are sometimes called gabapentinoids, belong to a class of prescription drugs called anticonvulsants, which is why they are often prescribed for seizure management. These medications also have neuropathic propertiesthat is, they treat nerve pain.
If you experience chronic nerve pain in your spine, it might feel like weakness, shooting pain, burning, and/or tingling throughout your back and neck. Sometimes pain radiates into an extremity, such as an arm or leg . Gabapentinoids can help ease those sensory symptoms in some people. Gabapentin may even be prescribed to treat nerve pain after spinal cord injury.
Gapapentin For Neuropathic Pain
Introduction Gabapentin has FDA indication to treat postherpetic neuralgia and partial onset seizures. Controlled clinical trials in diabetic neuropathy and postherpetic neuralgia show that gabapentin at 2400-3600 mg/day has a similar efficacy to tricyclic antidepressants and carbamazepine. Consistent, though less compelling clinical evidence supports its use for neuropathic cancer pain, pain associated with HIV infection, chronic back pain and others . Due to this emerging evidence, it is widely used for the treatment of neuropathic pain. The exact mechanism and site of action of gabapentin is unknown. Gabapentin is generally well-tolerated, easily titrated, has few drug interactions, and does not require laboratory monitoring. However, cost may be a limiting factor for some patients. Patients suitable for gabapentin should have a clear neuropathic pain syndrome, characterized by sharp, shooting, lancinating and/or burning pain, in a nerve root or stocking/glove distribution. See Fast Fact #289 for a comparison of gabapentin with pregabalin a similar neuropathic analgesic.
Pediatric Use There is limited data available assessing its effectiveness in neuropathic pain in children. The American Pain Society recommends that gabapentin be considered for pediatric neuropathic pain especially when concurrent analgesics are found to be too sedating. Their recommended initial dose is 2 mg/kg/day with a usual dosage range of 8 to 35 mg/kg/day divided into 3 daily doses.

How To Switch To A Gabapentin Alternative
If you have not been experiencing the relief you had hoped for with gabapentin, there are several natural and pharmaceutical options available to you. Before any changes are made, discussions on how to properly begin new treatments should be reviewed with your healthcare provider. The following steps should be taken first before any changes to your medications occur:
- Review all side effects currently experienced while taking gabapentin with your provider.
- Discuss the amount of pain relief not being achieved while taking the medication.
- If there are any difficulties with taking the medication during its recommended times, this should also be disclosed.
- Study other treatment options that you may be interested in so an open discussion can be had with your provider.
- Review costs associated with the alternatives to ensure they are viable financial options.
When an alternative is found for the replacement of gabapentin, it is important that gabapentin is slowly tapered off. If being used for the treatment of seizures, gabapentin cannot be abruptly stopped as it can cause increased episodes of seizures. Withdrawal symptoms have also been linked with suddenly discontinuing gabapentin. When a gradual transition plan is made with your healthcare provider, this reduces the potential of complications when stopping gabapentin. Gradual reduction of this medication is important so that the new alternative treatment can be started safely.
How To Take It
You should take it with a tall glass of water, with or without food. You should never increase your intake of gabapentin without your medical practitioners knowledge and approval. You may notice the benefits of taking gabapentin after a few days or two months, as it differs from person to person.
Others may need to increase the dosage of gabapentin, if required, for it to be effective. In the event you forget or miss your daily dose, you need to take it as soon as you remember. The only time that you should not take it immediately is if it is time for you to take your next dose. If that is the case, you need to skip the missed dose and take the next dose as you would normally do. You should never take two capsules at the same time.
However, gabapentin does not work for everyone. If you do not notice a difference in the severity of your pain after 6 to 8 weeks, you need to stop talk to your medical practitioner before you stop taking gabapentin.
You should never stop taking gabapentin or any other medication for that matter abruptly. If you suddenly stop taking it, you will experience withdrawal symptoms. Your medical practitioner will gradually wean you off them.

Why It Is Important To Do This Review
Some, but not all, antiepileptics can reduce neuropathic pain . Gabapentin is an antiepileptic widely prescribed for neuropathic pain, and it is common practice in some countries to aim for the maximum tolerated dose. There is growing controversy over whether this practice is justified by experimental evidence from doubleblind randomised trials. Guidance on prescribing typically puts gabapentin amongst the firstline agents . Despite this guidance based on good evidence, prescribing for neuropathic pain often involves paracetamol or paracetamol combined with opioids , for which there is no evidence of efficacy .
The standards used to assess evidence in chronic pain trials have evolved substantially in recent years, with particular attention being paid to trial duration, withdrawals, and statistical imputation following withdrawal, all of which can substantially alter estimates of efficacy . The most important change is the move from using mean pain scores, or mean change in pain scores, to the number of people who have a large decrease in pain and who continue in treatment, ideally in trials of 8 to 12 weeks’ duration or longer. Pain intensity reduction of 50% or more correlates with improvements in comorbid symptoms, function, and quality of life. These standards are set out in the PaPaS Author and Referee Guidance for pain studies of Cochrane Pain, Palliative and Supportive Care .

Serious breathing problems can happen if you take gabapentin with drugs that cause severe sleepiness or decreased awareness. Some examples include narcotic opioids, anti-anxiety medicines, antidepressants, and antihistamines. If you are 65 years of age or older and/or have a condition that affects your lungs, such as chronic obstructive pulmonary disease , there is an increased risk for breathing problems. Watch for increased sleepiness or decreased breathing when you start taking gabapentin or when the dose is increased. Get help right away if you develop breathing problems.
Seek immediate medical attention if these symptoms develop:
- Slowed, shallow or trouble breathing.
- Unresponsiveness .
- Bluish-colored or tinted skin, especially on lips, fingers or toes.

Additional Information For Patients And Caregivers
- FDA is warning that serious breathing difficulties may occur when gabapentin or pregabalin is taken with other medicines that depress the central nervous system such as opioids, in those patients who have underlying respiratory problems, or in the elderly. There is less evidence supporting the risk of serious breathing difficulties with gabapentinoids alone in otherwise healthy individuals, and we will continue to monitor this population for additional evidence.
- Respiratory problems can be life-threatening, so seek medical attention immediately if you or someone you are caring for experiences the following symptoms:
- Confusion or disorientation
- Extreme sleepiness
- Slowed, shallow, or difficult breathing
- Unresponsiveness, which means the person doesnât answer or react normally or you canât wake them up
