Neurontin (gabapentin) side effects:
Common side effects include: fatigue, tiredness, drowsiness, blurred or double vision, unusual eye movements, and shaking (tremors). If these effects persist or become worse talk to your pharmacist or doctor immediately.
Before prescribing Neurontin your doctor will determine if the potential side effects outweigh the possible benefits. Most people taking Neurontin (gabapentin) do not experience severe side effects.
Some patients are prescribed Neurontin for psychological conditions such as bipolar disorder. In a small number of patients this may cause increased depression or other mood disturbances, which may contribute to suicidal thoughts or actions. Tell your doctor immediately if you or a loved one notices any sudden changes in mood or behavior.
A very small percentage of people taking Neurontin may experience swelling of the hands, feet, ankles, or other extremity locations. Shallow or labored breathing may also occur. These are potentially life threatening reactions and medical help should be sought immediately.
In very rare cases patients may have a severe allergic reaction to Neurontin. Symptoms include a full-body rash, fever, swollen lymph nodes, and a swollen tongue and / or throat. Difficulty breathing may occur. If any of these occur seek emergency medical attention immediately.
