Aetiology

DMARDs

  • If patient who is on a DMARD presents with rash, oral ulceration, nausea/vomiting, diarrhoea, dry cough, or new onset/increasing dyspnea should have treatment withheld and specialised advice taken
  • In the event of a severe sore throat or abnormal bruising, treatment should be withheld, an urgent FBC taken and any blood test abnormalities discussed with specialist team
    • Provide symptomatic relief
    • Consider prescribing an antibiotic, taking into account potential interactions with DMARDs
