When a medicine interaction or adverse incident is suspected, it is important to act promptly and monitor the person closely for any worsening symptoms or unexpected changes. This may include monitoring for side effects such as dizziness, confusion, allergic reactions, breathing difficulties, stomach problems, seizures, changes in mood, or changes in blood pressure and heart rate, depending on the medicines involved. The medication should not usually be stopped abruptly unless advised by a healthcare professional, particularly with medicines such as anti-epileptic drugs, antidepressants, or steroids. Any concerns should be reported immediately to a pharmacist, GP, specialist, or emergency services if symptoms are severe. All incidents and actions taken should be accurately documented, including the medicines involved, symptoms observed, timing, advice received, and outcomes. Follow-up monitoring should continue until the person has stabilised and any necessary medication reviews or adjustments have been completed. The incident can then be formally closed once risks have been addressed, the person is safe, records are updated, and any lessons learned or preventative measures have been communicated to reduce the chance of recurrence.
