Other warnings you should know about:

Stopping your treatment: Do NOT suddenly stop taking NEURONTIN without talking to your healthcare professional first. If you do this, it may cause you to:

  • have more seizures; or

  • experience other withdrawal symptoms such as anxiety, sleeplessness, nausea, pain and/or sweating, shaking (tremor), headache, depression, dizziness, or feeling abnormal or unwell. Stopping your treatment must be a gradual process that you discuss with your healthcare professional.

Dependence/Tolerance: Even when NEURONTIN has been taken exactly as directed, there have been some cases of abuse, misuse, addiction, physical dependence and withdrawal. Your healthcare professional will monitor you while you are taking NEURONTIN. If you feel like you are craving NEURONTIN, or not using it as directed, talk to a healthcare professional right away.

Pregnancy: If you take NEURONTIN during the first trimester of your pregnancy, your baby may be at risk for serious birth defects. Do not take NEURONTIN if you are pregnant (or think you might be pregnant), unless advised by your healthcare professional. You must use an effective birth control method while taking NEURONTIN if you are able to get pregnant. If you are planning on becoming pregnant, talk to your healthcare professional before taking NEURONTIN.

Pregnancy registry: If you become pregnant while taking NEURONTIN, talk to your healthcare professional about registering with the North American Antiepileptic Drug Pregnancy Registry. You can enroll in this registry by calling 1-888-233-2334. The purpose of this registry is to collect information about the safety of antiepileptic medicines during pregnancy. Information on the registry can also be found at the following website: http://www.aedpregnancyregistry.org/.

This includes skin conditions such as Stevens-Johnson syndrome (SJS)/ toxic epidermal necrolysis (TEN), erythema multiforme (EM), and drug reaction with eosinophilia and systemic symptoms (DRESS). The following symptoms may be related to these skin reactions:

  • Fever

  • severe rash

  • swollen lymph glands

You may find it helpful to tell a relative or close friend how you are feeling and ask them to tell you if they notice any changes in your behaviour.

Driving and using machines: Do not drive at all if you have uncontrolled epilepsy. NEURONTIN may cause you to feel dizzy or drowsy. Avoid driving, using machinery, or doing dangerous activities until you know how NEURONTIN affects you.
