If behaviour changes after starting, stopping or changing a medicine, record the medicine name, dose, timing, symptoms, sleep and appetite. Contact the prescribing clinician or pharmacist promptly; do not stop, restart or adjust a prescription without advice unless emergency services direct you. Some effects may be temporary, while others need urgent review or a different dose. Ask what the medicine targets, when benefits should appear, which side effects are expected and what requires immediate help. Bring all medicines, supplements and steroid details to appointments. Seek urgent care for breathing problems, facial swelling, fainting, severe rash, seizures, extreme sleepiness or thoughts of self-harm. Report suspected reactions through the appropriate national pharmacovigilance service.
