Gabapentin is a medication used to treat epilepsy and neuropathic pain. It is also used to manage postherpetic neuralgia, a condition that causes pain after shingles. While it is a useful medication, it can cause side effects such as suicidal thoughts, depression, clumsiness, dizziness, drowsiness, and abnormal behaviours. In rare cases, gabapentin can cause serious allergic reactions, including anaphylaxis and angioedema, which can be life-threatening. In addition, there have been reports of gabapentin causing myoclonus, a condition characterised by involuntary muscle jerks or spasms. This has been observed in patients with pre-existing myoclonus, mental retardation, chronic static encephalopathy, diffuse brain damage, impaired renal function, or end-stage renal disease.

What You'll Learn
Gabapentin can cause myoclonus, a type of muscle spasm
Gabapentin is a medication used to treat neuropathic pain, epilepsy, and postherpetic neuralgia (pain after shingles). It is an anticonvulsant and analgesic medication that works in the brain to prevent seizures and relieve pain for certain conditions in the nervous system. While gabapentin has a favourable safety profile, it can cause some side effects, including muscle spasms or myoclonus.
Myoclonus is a rare side effect of gabapentin, and it has been reported in patients with pre-existing myoclonus, mental retardation, chronic static encephalopathy, diffuse brain damage, impaired renal function, or end-stage renal disease. In one case, a 69-year-old female patient without any previous disorders developed myoclonus after being administered gabapentin post-surgery. The co-administration of tramadol, an opioid, and gabapentin may have mutually enhanced the myoclonic potential of each drug. The discontinuation of gabapentin led to the resolution of myoclonus symptoms within two days.
Another case report describes a 69-year-old man with a history of traumatic brain injury, peripheral neuropathy, amnesia, and post-traumatic stress disorder who experienced acute onset muscle spasms or myoclonus while taking a high dose of gabapentin (9600 mg per day). The physical examination revealed stimulus-sensitive myoclonus, painful muscle spasms in all extremities, and myokymia in his calves.
It is important to note that not everyone experiences side effects from taking gabapentin, and the common side effects are usually mild and go away on their own. However, if side effects do occur, they may need medical attention. Gabapentin may also cause serious allergic reactions, including anaphylaxis and angioedema, which can be life-threatening. Other possible side effects include vision changes, clumsiness, unsteadiness, dizziness, drowsiness, sleepiness, abnormal behaviours, and mood changes.

It can cause respiratory depression, a serious breathing problem
Gabapentin is a medication used to treat neuropathic pain, epilepsy, and postherpetic neuralgia. It is an anticonvulsant that works in the brain to prevent seizures and relieve pain for certain conditions in the nervous system. While it has a favourable safety profile, there are some side effects associated with its use.
One serious potential side effect of gabapentin is respiratory depression, a life-threatening breathing problem. This can occur when gabapentin is used in conjunction with narcotic pain medications or central nervous system (CNS) depressants, including opioids. The FDA has issued a warning about the risk of respiratory depression with gabapentin, as it can be fatal. People taking gabapentin should be aware of this risk and seek medical attention if they experience any breathing difficulties.
Respiratory depression is a condition in which breathing becomes slow and shallow, and can eventually stop altogether. It is a life-threatening emergency that requires immediate medical attention. Signs of respiratory depression include pale or blue lips, fingernails, or skin, difficulty breathing, and irregular, fast or slow, or shallow breathing. If you or someone you know is experiencing these symptoms, seek medical help right away.
In addition to respiratory depression, gabapentin has been associated with other serious side effects, including allergic reactions such as anaphylaxis and angioedema, which can also be life-threatening. It can also cause mood changes, abnormal behaviours, and suicidal thoughts. Some people may also experience muscle spasms, as evidenced by a case report of a 69-year-old man who presented to the hospital with acute onset muscle spasms after taking a prescribed dose of 9600 mg of gabapentin daily.
It is important to note that not everyone will experience side effects from taking gabapentin, and many of the side effects are usually mild and go away on their own. However, it is crucial to be aware of the potential risks and to consult a doctor if any concerning symptoms occur. Additionally, do not stop taking gabapentin without first checking with your doctor, as stopping suddenly can increase the risk of seizures.

It may cause allergic reactions, including anaphylaxis and angioedema
While gabapentin is a useful medication for treating seizures and relieving pain for certain nervous system conditions, it may cause allergic reactions, including anaphylaxis and angioedema. Anaphylaxis is a severe allergic reaction that involves the whole body and can be life-threatening. Symptoms of anaphylaxis may include hives, itching, swelling, difficulty breathing, a fast heartbeat, and confusion. It is important to seek immediate medical attention if you experience any of these symptoms while taking gabapentin.
Angioedema is another allergic reaction that can occur with gabapentin use. It involves swelling that typically occurs in the face, mouth, or throat, and can also be life-threatening. Angioedema may cause difficulty breathing and swallowing, and requires immediate medical attention. If you experience any signs of angioedema, such as swelling in the face, mouth, or throat, it is crucial to seek medical help right away.
In addition to anaphylaxis and angioedema, gabapentin can also cause Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome, a severe allergic reaction that can progress to damage major organs, including the liver, kidneys, or heart. DRESS syndrome typically begins with fever, rash, and swelling of the lymph nodes. As with anaphylaxis and angioedema, DRESS syndrome is a medical emergency that necessitates immediate medical treatment.
It is important to be aware of these potential allergic reactions and to seek medical advice if you experience any unusual or allergic reactions while taking gabapentin. The decision to use gabapentin involves weighing the risks against the benefits, and your doctor can help you make an informed choice.

Gabapentin can cause dizziness and drowsiness
Gabapentin is a prescription medicine used to control seizures in patients with epilepsy and to manage postherpetic neuralgia, or pain after shingles. It is an anticonvulsant that works in the brain to prevent seizures and relieve pain for certain conditions in the nervous system.
Gabapentin is considered to have a favourable safety profile with few drug interactions. However, it can cause side effects, especially if misused. The most common side effects of gabapentin are dizziness and drowsiness, occurring in 20% to 30% of patients. These side effects may improve over time, but they can make it difficult to perform activities that require alertness, such as driving or operating heavy machinery. It is important to know how you react to this medication before engaging in any potentially dangerous activities.
Other side effects of gabapentin include clumsiness, unsteadiness, vision changes, sleepiness, and trouble with thinking. In rare cases, gabapentin can cause fluid buildup (edema), weight gain, and vision problems. It can also lead to diarrhoea, mood changes, and suicidal thoughts or behaviour. Combining gabapentin with certain medications, such as opioids or benzodiazepines, can increase the risk of difficulty breathing and overdose.
Gabapentin may also cause serious or life-threatening allergic reactions, such as anaphylaxis and angioedema, which require immediate medical attention. Additionally, there is a risk of withdrawal symptoms when discontinuing the medication, so it is important to gradually reduce the dose under medical supervision.

It may cause abnormal behaviour, like nervousness and hostility
Gabapentin is a prescription medication that is used to prevent and control partial seizures, relieve nerve pain following shingles, and treat restless leg syndrome. It is also used as a muscle relaxant and an anti-spasmodic. The medicine is available in capsule, tablet, and liquid form and works by decreasing abnormal activity in the brain.
While gabapentin is a useful medication, it can cause some people to display abnormal behaviour. This includes nervousness, restlessness, and hostility. In studies of children aged 3 to 12, gabapentin was found to cause mood changes in some participants. Up to 8% of children between the ages of 3 and 12 may experience aggressive behaviour, such as hostility, when taking gabapentin. Other abnormal behaviours that have been observed in some patients taking gabapentin include agitation, irritability, sadness, and hopelessness.
In addition to these behavioural changes, gabapentin has been linked to an increased risk of suicidal thoughts or behaviours in both children and adults. If you or your child experience any changes in behaviour or mood while taking gabapentin, it is important to contact your doctor or prescriber immediately. It is also important to note that stopping gabapentin suddenly can be dangerous and may increase your risk of seizures. Therefore, it is recommended to gradually reduce the dosage under the supervision of a doctor.
