You can take gabapentin 100 mg with or without food, but it’s best to do the same each day.
Try to space your doses evenly through the day. For example, you could take it first thing in the morning, early afternoon and at bedtime.
If you or your child are taking a liquid, it will come with a plastic syringe or spoon to measure your dose. If you do not have a syringe or spoon, ask your pharmacist for one. Do not use a kitchen spoon, as it will not measure the right amount.
