GABA-300 (QMED)

# Gabapentin 300 mg ## SHORT DESCRIPTION **Gabapentin 300 mg** is a prescription medicine primarily used to treat **nerve pain (neuropathic pain)** and as an **add-on treatment for certain types of seizures**. It belongs to a group of medicines called **gabapentinoids/anticonvulsants**. Gabapentin may be prescribed for nerve pain associated with conditions such as diabetic neuropathy or shingles (postherpetic neuralgia). It is also used as adjunctive therapy for partial-onset seizures. ## KEY BENEFITS * Helps relieve neuropathic or nerve-related pain * May reduce burning, shooting, tingling, or electric-shock-like nerve pain * Used for postherpetic neuralgia (nerve pain following shingles) * May be used for diabetic peripheral neuropathy when clinically appropriate * Helps control certain partial-onset seizures when used with other anticonvulsant medicines * Can reduce abnormal nerve signalling involved in pain and seizures ## USES / INDICATIONS Gabapentin 300 mg may be prescribed for: * **Neuropathic pain** * Postherpetic neuralgia * Certain diabetic nerve pain conditions * Other forms of peripheral neuropathic pain when clinically appropriate * Adjunctive treatment of partial-onset seizures Gabapentin may also be prescribed for other conditions in some clinical settings, but such uses may be **off-label** and should only be undertaken under medical supervision. ## HOW IT WORKS Gabapentin is structurally related to the neurotransmitter GABA, but it **does not act directly on GABA receptors**. It primarily binds to the **alpha-2-delta subunit of voltage-gated calcium channels** in the nervous system. This reduces the release of certain excitatory neurotransmitters and helps decrease abnormal nerve signalling. This action can reduce neuropathic pain and help control abnormal electrical activity associated with certain seizures. ## DOSAGE & ADMINISTRATION * Take Gabapentin 300 mg exactly as prescribed. * The starting dose may be lower than 300 mg, with gradual dose adjustment depending on the condition and individual response. * Your doctor may divide the daily dose into multiple doses. * Swallow capsules or tablets with water. * Gabapentin may generally be taken **with or without food**. * Take doses at evenly spaced times when prescribed multiple times per day. * Do not increase the dose without medical advice. * Do not stop gabapentin suddenly, particularly if it is being used for seizure control. ### Kidney function Gabapentin is eliminated primarily through the kidneys. People with reduced kidney function may require a lower dose or different dosing schedule. ### Missed dose Take the missed dose when remembered unless it is nearly time for your next dose. Do not take two doses together to compensate for a missed dose. ## SIDE EFFECTS Common side effects may include: * Drowsiness * Dizziness * Fatigue * Headache * Blurred or double vision * Unsteadiness or difficulty coordinating movements * Swelling of the hands, feet, or ankles * Nausea * Weight gain * Dry mouth These effects may be more noticeable when treatment is first started or after the dose is increased. ### Serious side effects Seek urgent medical attention for: * Difficulty breathing * Severe allergic reaction * Significant swelling of the face, lips, tongue, or throat * Severe skin rash or blistering * Persistent or severe weakness * New or worsening depression or suicidal thoughts * Severe confusion or unusual changes in behaviour Gabapentin can rarely cause serious hypersensitivity reactions and respiratory depression, particularly when combined with other medicines that depress the central nervous system. ## PRECAUTIONS & WARNINGS ### Drowsiness and dizziness Gabapentin can cause dizziness, sleepiness, and impaired coordination. Avoid driving, operating machinery, or performing hazardous activities until you know how the medicine affects you. ### Respiratory depression Gabapentin can cause serious breathing problems in susceptible people, particularly when combined with **opioids or other central nervous system depressants**. Seek immediate medical help if you experience unusually slow, shallow, or difficult breathing, extreme sleepiness, or difficulty waking. ### Kidney disease Tell your doctor if you have kidney problems. Gabapentin is cleared through the kidneys, and the dose may need to be adjusted. ### Dependence and withdrawal Gabapentin can cause physical dependence in some people. Do not suddenly stop long-term treatment without medical advice. Your doctor may gradually reduce the dose. ### Mental health Some patients taking anticonvulsant medicines may experience mood changes, depression, agitation, or suicidal thoughts. Report significant changes in mood or behaviour promptly. ### Pregnancy and breastfeeding Tell your doctor if you are pregnant, planning pregnancy, or breastfeeding. Your doctor will weigh the potential benefits and risks before recommending treatment. ## DRUG INTERACTIONS Tell your doctor or pharmacist about all medicines and supplements you take. Important interactions include: * **Opioid pain medicines** — may increase sedation and the risk of respiratory depression. * **Sleeping medicines and sedatives** — may increase drowsiness and impaired coordination. * **Benzodiazepines** — may increase central nervous system depression. * **Alcohol** — may increase dizziness and sedation. * **Antacids containing aluminum or magnesium** — can reduce gabapentin absorption. If you use an aluminum- or magnesium-containing antacid, it is generally recommended to separate it from gabapentin by **at least 2 hours**. Do not combine gabapentin with other sedating medicines unless your healthcare professional is aware of all your medications. ## STORAGE INFORMATION * Store Gabapentin 300 mg according to the manufacturer's instructions. * Keep at room temperature. * Protect from excessive heat and moisture. * Keep the medicine in its original packaging. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use capsules or tablets if the packaging is damaged or the medicine appears abnormal. ## PRESCRIPTION STATUS **Gabapentin 300 mg is generally a prescription medicine.** Because gabapentin can cause significant drowsiness, has important interactions, and may require dose adjustment in kidney disease, it should be used under the supervision of a qualified healthcare professional.
