Neurontin Warnings and Precautions

An understanding of Neurontin warnings and precautions can help ensure a safe treatment process. This includes knowing what side effects to watch for (such as behavioral problems in children or dizziness) and that an increased risk of side effects is possible if the medication is combined with alcohol. Neurontin warnings and precautions also extend to those with kidney disease or certain allergies.

Neurontin: What Should I Tell My Healthcare Provider?

You should talk with your healthcare provider prior to taking Neurontin® (gabapentin) if you have:
  • Kidney disease, including kidney failure (renal failure)
  • Any allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
  • Pregnant or thinking of becoming pregnant
  • Breastfeeding.
Make sure to tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.

Specific Neurontin Warnings and Precautions

Warnings and precautions to be aware of prior to taking Neurontin include the following:
  • The medication can cause emotional or behavioral problems, particularly in children. This may include hostility, hyperactivity, concentration problems, and other behavioral problems. Let your healthcare provider know if you notice any such changes in your child that are possibly due to Neurontin.
  • As with most seizure medications, stopping Neurontin too quickly can increase your risk of seizures and other problems (see Neurontin Withdrawal).
  • The medication increases the risk of certain cancers in rats. It is not known if Neurontin increases the risk of cancer in humans.
  • Make sure that you know how Neurontin affects you before driving or operating any machinery, as it can cause drowsiness and dizziness. In general, you should avoid alcohol while taking Neurontin, due to the risk of increasing drowsiness.
  • Neurontin can cause vision problems, especially blurred vision or double vision. Let your healthcare provider know if you notice any vision problems while taking it.
  • Let your healthcare provider know if you have kidney disease, as you may need a lower Neurontin dosage.
  • Neurontin can interact with other medications (see Neurontin Drug Interactions).
  • Neurontin is considered a pregnancy Category C medication. This means that it may not be safe for pregnant women, although the full risks are not known. Talk to your healthcare provider about the risks and benefits of taking the drug while pregnant (see Neurontin and Pregnancy).
  • Neurontin passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Neurontin and Breastfeeding).


  • Early evidence suggests that seizure medications, including Neurontin, may increase the risk of suicidal thoughts or behaviors (see Seizure Medications and Suicide for more information).
