If you are among many Americans who have trouble sleeping due to the uncontrollable urge to move your legs in the evening or while resting, you are likely familiar with the term <\/span>restless legs syndrome<\/span><\/a> (RLS).\u00a0<\/span><\/p>\n

Your healthcare provider may have already diagnosed you with this condition and reviewed some available treatment options. The cause of <\/span>restless legs syndrome<\/span><\/a> is still unknown, but there has been some consensus that an imbalance of dopamine in the brain may contribute to the cause. No set diagnostic tests are available to diagnose this condition. Therefore, your healthcare provider needs to take a thorough history and perform a physical exam to make an accurate diagnosis.\u00a0<\/span><\/p>\n

Some risk factors or medical conditions are associated with developing restless legs syndrome. These include pregnancy or any conditions that cause hormonal changes, kidney problems, peripheral neuropathy, vitamin deficiencies, vascular disease, back injuries, sleeping disorders, and Parkinson\u2019s disease. The use of alcohol, caffeine, and nicotine is also linked to restless legs syndrome.\u00a0<\/span><\/p>\n

Although there is no cure for severe primary RLS, there is medical help available to improve symptoms associated with this nerve disorder.\u00a0<\/span><\/p>\n

Does gabapentin help with restless leg syndrome (RLS)?<\/span><\/h2>\n

Yes. <\/span>Gabapentin enacarbil<\/span><\/a> is a type of <\/span>anticonvulsant<\/span><\/a> approved by the U.S. Food and Drug Administration (FDA) for the treatment of moderate to severe primary RLS. It is known as a prodrug of gabapentin. The difference between gabapentin and gabapentin enacarbil is that gabapentin enacarbil is taken once daily, whereas gabapentin can be taken up to three times a day.\u00a0<\/span><\/p>\n

Gabapentin was initially developed for seizures and postherpetic neuralgia but has become a popular option for the management of symptoms associated with moderate to severe primary RLS with the prodrug option. How gabapentin works to improve nerve pain is still unknown. It is believed to target calcium channels in the brain, normalizing neurotransmitters. This then enhances the nerve signals in the legs, not the muscles.<\/span><\/p>\n

Typically, gabapentin is started at a <\/span>very low dose<\/span><\/a> and gradually increased to reach maximum effectiveness without symptoms. Since each person is different, different doses and frequencies may be needed individually to improve primary RLS. Therefore, it may take some time to find the optimal dose. However, once the appropriate dose has been found, typically, relief of symptoms can be seen in about 4 weeks after initiation of gabapentin. Because restless legs symptoms are usually more pronounced in the evening, gabapentin is generally recommended during this time. One of the most common side effects of use of gabapentin is drowsiness. Therefore, the medication is also better tolerated when taken in the evening.<\/span><\/p>\n

Gabapentin dosage for restless legs<\/span><\/h2>\n

When you and your medical doctor decide to use medications, the safety of gabapentin enacarbil will be discussed. To reduce the serious side effects of gabapentin, usually a very low dose is initiated. The <\/span>minimum dose<\/span><\/a> started while treating restless legs syndrome is 300 mg once daily. Patients typically report minimal to no improvement of symptoms at this dose. Still, a slower approach to prescribing this medication may be taken to ensure there are no serious adverse effects of gabapentin enacarbil.\u00a0<\/span><\/p>\n

The best results are seen with the recommended standard dose of 600 mg once daily. The maximum daily dosage of gabapentin enacarbil is 1800 mg. Higher doses than this may lead to less tolerance of gabapentin enacarbil. Caution should be taken if higher doses are needed for symptom relief.\u00a0<\/span><\/p>\n

Gabapentin is taken long-term and should be reevaluated by your physician every three months. If the symptoms of restless legs syndrome are mild or infrequent, as-needed options such as <\/span>benzodiazepines<\/span><\/a>, <\/span>muscle relaxants<\/span><\/a>, or <\/span>opioids<\/span><\/a> may be more appropriate. If symptoms are not improving with the initial dose, communication with your physician is key, as they will be able to adjust the dose to provide more symptom relief.<\/span><\/p>\n
