Before Using
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of gabapentin for treating partial seizures in children 3 years of age and older. However, safety and efficacy have not been established in children younger than 3 years of age.
Appropriate studies have not been performed on the relationship of age to the effects of gabapentin for treating postherpetic neuralgia in children. Safety and efficacy have not been established.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of gabapentin in the elderly. However, elderly patients are more likely to have unwanted effects (eg, problems with balance or walking, swelling in the feet or legs) and age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving gabapentin.
Breastfeeding
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Precautions of Taking Gabapentin
It is very important that your doctor check your or your child’s progress at regular visits to make sure this medicine is working properly. Blood tests are needed to check for unwanted effects.
Check with your doctor right away if you have a fever, rash, swollen, painful, or tender lymph glands in the neck, armpit, or groin, unusual bleeding or bruising, or yellow eyes or skin. These may be symptoms of a serious and life-threatening allergic reaction called drug reaction with eosinophilia and systemic symptoms (DRESS) or multiorgan hypersensitivity.
This medicine may cause serious allergic reactions, including anaphylaxis and angioedema, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.
Gabapentin may cause vision changes, clumsiness, unsteadiness, dizziness, drowsiness, sleepiness, or trouble with thinking. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert, well-coordinated, or able to think or see well. If these side effects are especially bothersome, check with your doctor.
This medicine may cause some people to be agitated, irritable, or display other abnormal behaviors, such as feeling sad or hopeless, getting upset easily, or feeling nervous, restless, or hostile. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed, even after stopping the medicine. If you, your child, or your caregiver notice any of these side effects, tell your doctor right away.
This medicine will add to the effects of alcohol and other CNS depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds, sedatives, tranquilizers, or sleeping medicines, prescription pain medicine or narcotics, other medicines for seizures (eg, barbiturates), muscle relaxants, or anesthetics, including some dental anesthetics. Check with your medical doctor or dentist before taking any of the above while you or your child are using gabapentin.
This medicine may cause respiratory depression, a serious breathing problem that can be life-threatening, when used together with narcotic pain medicines. Check with your doctor right away if you have pale or blue lips, fingernails, or skin, difficult or trouble breathing, or irregular, fast or slow, or shallow breathing.
Do not stop using gabapentin without checking with your doctor. Stopping the medicine suddenly may increase the risk for seizures. Your doctor may want you or your child to gradually reduce the amount you are taking before stopping it completely.
Make sure any doctor or dentist who treats you knows that you are using this medicine. This medicine may affect the results of certain medical tests.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
