Potential Side Effects of Taking Gabapentin
Gabapentin is taken by mouth and available as a capsule, tablet, or liquid. Dosages range from 300 to 3600 milligrams (mg) a day, though they are often adjusted for children, older people, and those with kidney disease.
The medication is available as an immediate-release oral tablet, an extended-release oral tablet, and an oral solution. It can be taken with or without food.
If you forget to take your dose, take it as soon as you remember. Never try to catch up by taking two capsules at once. Never stop taking gabapentin without your healthcare provider’s approval. You will need to wean yourself off it slowly to avoid potentially serious side effects.
Potential Side Effects
Like all drugs, gabapentin does have potential adverse effects, with the most common ones being dizziness and drowsiness. Less common but serious side effects include:
- Loss of coordination
- Blurred/double vision
- Unusual eye movements (nystagmus) or shaking (tremor)
- Swelling of the hands, ankles, or feet
Tell your healthcare provider right away if any of these side effects occur.
A small number of people who take anticonvulsants for any condition may experience depression, suicidal thoughts/attempts, or other mental/mood problems. Tell your healthcare provider right away if you or a loved one notice any unusual or sudden changes in your mood, thoughts, or behavior including signs of depression, suicidal thoughts, or thoughts about harming yourself.
A very serious allergic reaction to gabapentin is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including fever, swollen lymph nodes, rash, itching/swelling (especially of the face, tongue, or throat), severe dizziness, or trouble breathing.
