Active substance: Gabapentin
However, pairing an opioid with any CNS depressant — a gabapentinoid, benzodiazepine, sedating antidepressant, sedating antipsychotic, antihistamine, or other product — will increase the risk of respiratory depression.
The gabapentinoid prescribing information already includes guidance for health care professionals to caution patients about dizziness, somnolence, and the potential for impaired ability to operate a car or complex machinery.
What did FDA find? We reviewed several sources of data, including case reports submitted to FDA or published in the medical literature, observational studies, clinical trials, and animal studies.
Reports submitted to FDA and data from the medical literature show that serious breathing difficulties can occur when gabapentinoids are taken by patients with pre-existing respiratory risk factors.
We also reviewed the results of two randomized, double-blind, placebo-controlled clinical trials in healthy people, three observational studies, and several studies in animals.
All medicines have side effects even when used correctly as prescribed, but in general the benefits of taking a medicine outweigh these risks.
It is important to know that people respond differently to all medicines depending on their health, other medicines they are taking, the diseases they have, genetics, and many other factors.
As a result, we cannot determine the likelihood that someone will experience these side effects when taking gabapentinoids.
Your personal health care professional knows you best, so always tell them about all other medicines you are taking and if you experience any side effects while taking your medicines.
How do I report side effects from gabapentinoids?
Facts about Gabapentinoids Gabapentinoids include gabapentin and pregabalin. They are FDA-approved to treat a variety of conditions including partial seizures; pain from damaged nerves that follows spinal cord injury, healing of shingles, or diabetes; fibromyalgia; and moderate to severe primary restless legs syndrome.
Gabapentin is marketed under the brand names Neurontin and Gralise, and as generics. Gabapentin enacarbil is a prodrug of gabapentin marketed under the brand name Horizant.
A human abuse liability evaluation was not conducted when gabapentin was developed in the 1980 s and early 1990 s. Gabapentin is available as a tablet, capsule, solution, and extended-release tablet.
Pregabalin is marketed under the brand names Lyrica and Lyrica CR, and as generics. Pregabalin is available as a capsule, solution, and extended-release tablet. Common side effects of gabapentinoids include drowsiness, dizziness, blurry or double vision, difficulty with coordination and concentration, and swelling of the hands, legs, and feet.
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.
Do not take more of the medicine or take it more often than prescribed because doing so can cause serious problems or death.
Always tell all your health care professionals about all the medicines you are taking, including prescription and over-the-counter OTC medicines.
It is helpful to keep a list of all your current medicines in your wallet or another location where it is easily retrieved. You can fill out and print a copy of My Medicine Record. First, myofascial pain represents a heterogeneous group of disorders, each characterized by its own unique pathophysiology.
There are considerable differences in the mechanisms underlying acute muscle injury such as occurs with muscle tears and succinylcholine-induced myalgia and those responsible for chronic conditions in which muscles play a role, such as MPS and TMD.
For example, in TMD, the primary source of pain is myogenous in some patients and arthrogenous in others.
Many clinical investigators have not or perhaps could not distinguish between different pain generators. For some agents, such as topical nonsteroidal antiinflammatory drugs NSAIDs and quinine, the indications for use are relatively narrow, but for drug classes that act on a broad range of systems, such as antidepressants, their antinociceptive effects are not limited to myofascial pain.
