Inclusion Body Myositis (IBM)
- Dietary supplements or a gastrostomy feeding tube may be necessary.
- In combination with respiratory weakness, there is an increased risk of aspiration pneumonia.
- Swallowing difficulties may be temporarily worsened by intercurrent or systemic illness.
Medication and anaesthetic precautions
- Local anaesthetics and nitrous oxide are safe (for example, for minor dental procedures).
- Statins are usually well tolerated but caution should be exercised at high doses. There is a risk of side-effects in the muscles, which will exacerbate existing muscle weakness.
- Immunisations should be kept up-to-date, including flu vaccine.
- Immunosuppression does not help the majority of patients with IBM and should only be given under expert neuromuscular care.
