How does gabapentin work?
Gabapentin reduces the activity of overactive nerve signals, helping to relieve nerve pain, prevent seizures, and in some cases, reduce migraines.
What is gabapentin used to treat?
Gabapentin is commonly prescribed for:
- Nerve pain (e.g., sciatica, diabetic neuropathy, post-shingles pain)
- Epilepsy (to prevent seizures, usually alongside other medicines)
- Migraine prevention (in some cases)
- Restless legs syndrome (RLS) (occasionally prescribed off-label)
Who can take gabapentin?
Gabapentin is usually prescribed for adults and children over 6 years old for epilepsy and for adults only for nerve pain.
Who might not be able to take gabapentin?
Gabapentin may not be suitable if you:
- Have kidney disease (your dose may need adjusting)
- Have had a history of drug or alcohol dependence
- Are taking other medicines that cause drowsiness or dizziness
- Have breathing problems
Can I take gabapentin if I’m pregnant or breastfeeding?
Gabapentin is not usually recommended during pregnancy unless advised by a doctor. If you are breastfeeding, gabapentin may pass into breast milk, so consult your doctor for advice.
What if I miss a dose?
If you forget a dose, take it as soon as you remember. If it’s nearly time for your next dose, skip the missed one—don’t take two doses at once.
How effective is gabapentin?
Gabapentin can significantly reduce nerve pain, prevent seizures, and in some cases, help with migraines, but it may take a few weeks to feel the full effects.
What should I do if I take too much?
Taking too much gabapentin can cause severe drowsiness, confusion, difficulty breathing, or even loss of consciousness. If you think you’ve taken too much, seek medical help immediately.
What dose of gabapentin is usually taken?
Doses vary depending on the condition:
- Nerve pain: 300mg once daily, increasing to 900mg to 3600mg per day
- Epilepsy: 900mg to 3600mg per day, divided into three doses
Your doctor will start you on a low dose and increase it gradually if needed.
