Monitoring recommendations: Baseline investigations: Full blood count, B12 level, folate, and intrinsic factor antibodies (if pernicious anaemia suspected) During initial treatment: Potassium monitoring in severe deficiency (risk of hypokalaemia) Follow-up: Repeat full blood count after 8 weeks to confirm haematological response Long-term: Annual review to ensure compliance with maintenance injections
