Frequently Asked Questions
Common questions and answers about Gabapentin
General Questions
What is Gabapentin used for?
Gabapentin is primarily used to treat epilepsy (seizures) and certain types of nerve pain, including postherpetic neuralgia (pain after shingles). It's also sometimes prescribed off-label for other conditions like restless leg syndrome, anxiety, and chronic pain conditions.
How does Gabapentin work?
Gabapentin works by binding to calcium channels in nerve cells, which helps reduce the release of certain neurotransmitters. This action helps stabilize electrical activity in the brain and reduces abnormal nerve signals that cause seizures and pain.
Is Gabapentin a controlled substance?
In most states, Gabapentin is not federally controlled, but some states have classified it as a controlled substance due to concerns about misuse. It's important to take it exactly as prescribed by your healthcare provider.
How long does it take for Gabapentin to work?
For seizures, Gabapentin may start working within a few days. For nerve pain, it may take several weeks to feel the full benefits. Your doctor may gradually increase your dose over time to find the most effective amount for you.
Dosage & Administration
What should I do if I miss a dose?
If you miss a dose, take it as soon as you remember. However, if it's almost time for your next dose, skip the missed dose and continue with your regular schedule. Never take a double dose to make up for a missed one.
Can I take Gabapentin with food?
Yes, Gabapentin can be taken with or without food. Taking it with food may help reduce stomach upset in some people. Try to take it the same way each time to maintain consistent levels in your body.
What happens if I suddenly stop taking Gabapentin?
You should never stop taking Gabapentin suddenly as this can cause withdrawal symptoms and may lead to seizures. Your doctor will typically reduce your dose gradually over time when discontinuing the medication.
How should I store Gabapentin?
Store Gabapentin at room temperature (68-77°F) in a dry place away from light and moisture. Keep it in its original container and out of reach of children and pets.
Side Effects & Safety
What are the most common side effects?
The most common side effects include drowsiness, dizziness, fatigue, and coordination problems. These often improve as your body adjusts to the medication. Contact your doctor if side effects are severe or persistent.
Can Gabapentin cause weight gain?
Yes, weight gain is a possible side effect of Gabapentin. This may be due to increased appetite or fluid retention. Maintain a healthy diet and exercise routine, and discuss any significant weight changes with your doctor.
Is it safe to drive while taking Gabapentin?
Gabapentin can cause drowsiness and dizziness, which may impair your ability to drive safely. Avoid driving until you know how this medication affects you. If you experience these side effects, do not drive or operate machinery.
Can I drink alcohol while taking Gabapentin?
You should avoid or limit alcohol consumption while taking Gabapentin. Alcohol can increase the sedative effects of the medication, leading to increased drowsiness, dizziness, and impaired coordination.
Special Situations
Is Gabapentin safe during pregnancy?
Gabapentin should only be used during pregnancy if the potential benefits outweigh the risks. It's important to discuss this with your healthcare provider if you're pregnant, planning to become pregnant, or breastfeeding.
Can elderly patients take Gabapentin?
Yes, but elderly patients may be more sensitive to side effects, particularly drowsiness and coordination problems. Doctors typically start with lower doses and monitor more closely in older adults.
What if I have kidney problems?
If you have kidney problems, your doctor may need to adjust your Gabapentin dose since the medication is eliminated through the kidneys. Be sure to inform your healthcare provider about any kidney issues.
