Gabapentin 300mg is often given to help with nerve pain. It works by soothing excessive nerve activity in the brain. Many people notice a big difference, especially those with neuropathy or pain from shingles. However, how well it works can differ from person to person. Some may have side effects like sleepiness, dizziness, or tiredness. It’s important to follow your doctor’s instructions when taking Gabapentin and talk about any worries, as the dose might need to be changed for the best results and fewer side effects.
