Actavis Gabapentin 300mg Capsules: Nerve Pain & Epilepsy UK Guide
Actavis Gabapentin 300mg Capsules contain 300 mg of gabapentin, an anticonvulsant medicine with neuropathic pain-relieving and anticonvulsant properties. Gabapentin may be prescribed for the treatment of peripheral neuropathic pain and as therapy for certain types of epilepsy, including partial seizures with or without secondary generalisation.
For adults prescribed Gabapentin 300mg, the appropriate dose depends on the medical condition, severity of symptoms, age, kidney function, individual response and other medicines being taken. Treatment is generally started at a lower dose and increased gradually according to response and tolerability. Gabapentin should not normally be stopped suddenly because abrupt discontinuation can cause withdrawal symptoms and, in people with epilepsy, may increase the risk of seizures.
What Is Actavis Gabapentin 300mg Used For?
- Peripheral Neuropathic Pain: Gabapentin may be prescribed for peripheral nerve pain in adults, including neuropathic pain associated with conditions such as painful diabetic neuropathy and post-herpetic neuralgia.
- Partial Seizures: Gabapentin is used for certain partial seizures with or without secondary generalisation and may be prescribed as adjunctive therapy where clinically appropriate.
- Epilepsy Treatment: In adults and adolescents aged 12 years and above, gabapentin may be used as monotherapy for certain partial seizure disorders.
- Nerve Pain Management: Gabapentin modifies abnormal nerve signalling involved in neuropathic pain and works differently from conventional opioid painkillers.
- Prescription Treatment: Gabapentin is a prescription-only medicine and should be taken according to an individual treatment plan provided by a healthcare professional.
- Individualised Treatment: The appropriate dose depends on the indication, age, kidney function, treatment response, tolerability and other medicines being taken.
Gabapentin treatment requires consistent dosing and medical monitoring. Dose adjustment may be necessary when kidney function is reduced, while missed doses or sudden discontinuation can affect seizure control in people being treated for epilepsy.
How Does Actavis Gabapentin 300mg Work?
Gabapentin acts on the nervous system and is structurally related to the neurotransmitter GABA, although it does not act directly on GABA receptors. It binds to the alpha-2-delta subunit of voltage-gated calcium channels and reduces the release of certain excitatory neurotransmitters. This modifies abnormal neuronal activity involved in seizures and decreases abnormal pain signalling associated with neuropathic pain. Through these effects, gabapentin can help reduce nerve pain and control certain partial seizures when used as prescribed.
How to Take Actavis Gabapentin 300mg Capsules
- Oral Administration: Take Gabapentin 300mg Capsules by mouth exactly as prescribed by your doctor or pharmacist.
- Initial Treatment: Gabapentin treatment is generally started at a lower dose and increased gradually according to individual response and tolerability.
- Nerve Pain: The usual adult dose for neuropathic pain may be within a total daily range of 900 mg to 3,600 mg, divided into three doses, with treatment generally introduced gradually.
- Epilepsy: For adults and adolescents aged 12 years and over, the usual total daily dose may be within the range of 900 mg to 3,600 mg divided into three doses, according to the individual treatment plan.
- Special Patient Groups: Older patients may require dose adjustment because kidney function can decline with age.
- Kidney Problems: Gabapentin is eliminated primarily through the kidneys, so patients with impaired kidney function require appropriate dose adjustment.
- With or Without Food: Gabapentin capsules can generally be taken with or without food and should be swallowed whole with water or another suitable drink.
- Consistent Treatment: Doses should be spaced evenly throughout the day where possible. Do not take two doses together to compensate for a missed dose unless specifically advised by a healthcare professional.
Treatment duration depends on whether gabapentin is being used for neuropathic pain or epilepsy. Some patients may require longer-term treatment, but the need for continued therapy should be regularly reviewed. When treatment needs to be stopped, the dose should normally be reduced gradually rather than discontinued suddenly.

Important Warnings and Precautions
- Antacids: Aluminium- or magnesium-containing antacids can reduce gabapentin absorption and should generally be taken at least 2 hours apart from gabapentin.
- Opioids: Combining gabapentin with opioid medicines can increase the risk of sedation and respiratory depression.
- CNS Depressants: Other medicines that cause drowsiness or central nervous system depression may increase sedation and impairment.
- Morphine: Morphine can increase gabapentin exposure, and the combination may increase central nervous system depression and require appropriate monitoring.
- Dependence and Addiction: Gabapentin can cause dependence and addiction, particularly with prolonged use or in patients with certain risk factors.
- Withdrawal Symptoms: Abrupt discontinuation can cause anxiety, difficulty sleeping, nausea, pain, sweating and other withdrawal effects.
- Seizure Risk: Patients taking gabapentin for epilepsy may experience seizures or worsening seizure control if treatment is stopped suddenly.
- Gradual Discontinuation: Regular gabapentin treatment should normally be tapered gradually under medical supervision rather than stopped abruptly.
- Driving and Machinery: Gabapentin can cause drowsiness, dizziness, reduced concentration and impaired coordination. Do not drive or operate machinery if you feel affected.
- Severe Allergic Reactions: Swelling of the face, lips, mouth or throat, breathing difficulties or other signs of severe allergy require urgent medical attention.
- Severe Skin Reactions: Serious skin reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis and DRESS have been reported and require urgent medical assessment.
Gabapentin should be used exactly as prescribed. Extra caution is required when treatment is started, the dose is changed or gabapentin is combined with opioids or other medicines that cause sedation. New or worsening suicidal thoughts, severe mood changes or unusual behaviour should be reported promptly to a healthcare professional.
Stopping Actavis Gabapentin 300mg Treatment
Gabapentin should not normally be stopped suddenly after regular treatment. Abrupt discontinuation can cause withdrawal symptoms and may increase the risk of seizures in people being treated for epilepsy. A healthcare professional can gradually reduce the dose where appropriate to minimise withdrawal effects and maintain control of the underlying condition.

Yes. Gabapentin capsules can generally be taken with or without food. They should be swallowed whole and taken according to the prescribed dosing schedule.
Can Gabapentin 300mg be used for epilepsy?

Can Gabapentin 300mg cause dependence?
Yes. Gabapentin can cause dependence and addiction, particularly with prolonged use or in people with certain risk factors. It should be taken exactly as prescribed and should not be shared with other people.
