Gabapentin is generally considered safe and well-tolerated, although it can cause side effects in some people. Less common side effects may include blurred vision, difficulty speaking, and mood changes. In rare cases, gabapentin can cause serious side effects such as allergic reactions, suicidal thoughts or actions, and respiratory failure.
As with any medication, it's important to take gabapentin exactly as prescribed by your doctor and to report any side effects or concerns promptly. Gabapentin may interact with other medications, so be sure to inform your doctor of all the medications you are taking, including over-the-counter drugs and supplements.
