A clinical negligence solicitor can assess whether a prescribing, dispensing or administration error fell below the reasonable standard of care and caused you injury or worsened your condition. They may obtain medical records, seek an independent medical opinion and calculate losses such as treatment costs, lost earnings and care needs. In England and Wales, the usual limitation period is three years from the incident or the date you first knew, or ought reasonably to have known, about the injury, although exceptions apply. Keep prescriptions, medication packaging, appointment notes and details of what happened, and consider speaking to a solicitor regulated by the SRA promptly.
