This community-driven feedback is pivotal in shaping public perception and provides valuable insights for healthcare providers, enabling them to offer better patient counselling and support.

Community pharmacy feedback

Community pharmacists often observe that patients tend to underreport side effects associated with gabapentin, primarily due to fear of stigma or a lack of understanding regarding the drug's purpose. Pharmacists play an indispensable role by engaging in discussions with patients, addressing their concerns, and reinforcing proper usage. This interaction not only alleviates worries but also enhances the overall experience for those using gabapentin.
