People taking gabapentin may need to call 999 in certain emergencies relating to the drug, according to NHS guidance. Gabapentin, while not strictly classified as a painkiller, is sometimes prescribed to help treat nerve pain, especially following an injury.
It may also be prescribed to treat pain relating to conditions such as shingles and diabetes. It is thought to help nerve pain by blocking signals relating to pain going through the brain and down the spine.
However, the medication is also regularly prescribed to treat epilepsy and is classed as an anticonvulsant. Typically, gabapentin is taken as capsules, tablets, or a liquid to be swallowed and is taken around three times a day.
NHS guidance highlights that most people who take gabapentin will not experience any side effects. And even those who do experience side effects will only have them mildly, and they should go away by themselves.
However, there may be some situations where you will experience serious side effects relating to gabapentin that may require a call to 999. Minor side effects relating to gabapentin use can include nausea, dry mouth, weight gain, and problems with memory.
However, some people may also experience more severe side effects such as suicidal thoughts or thoughts relating to self-harm, unexpected muscle pain or weakness, and hallucinations. Despite this, the NHS recommends that symptoms of these usually only warrant an urgent call to a doctor or 111.
Like many medications, it is possible to experience a severe allergic reaction to gabapentin, known as anaphylaxis, which can present a wide range of symptoms such as swelling in the throat and difficulty breathing. The NHS recommends calling 999 if you're taking gabapentin and experience any of the following:
There is also the risk of becoming addicted to gabapentin, especially if you take it over a longer period. If you experience withdrawal symptoms from stopping the medication, your doctor may advise slowly reducing your dose in order to avoid withdrawal.
The NHS states:"Do not stop taking gabapentin without talking to your doctor. Talk to your doctor if you're concerned about becoming physically dependent on gabapentin."
Keep in mind that the above-mentioned is not a complete list of side effects and full information should be available on the leaflet included in your medicine packet. Further guidance on side effects associated with gabapentin can be found on the NHS website here.
