Radiotherapy and its potential impact on MG symptoms is an important concern. While radiotherapy itself isn't directly listed as a known MG trigger, several related factors could increase risk during treatment.
Key concerns to be aware of include:
- Infection risk — Radiotherapy can weaken the immune system, and infections are one of the most common triggers of a myasthenic crisis
- Physical stress — The body stress of ongoing treatment can worsen MG symptoms
- Fatigue and heat — Both are known MG triggers and are common side effects of radiotherapy
- Medication interactions — Any additional medications given alongside radiotherapy should be checked for MG compatibility Given the current Mestinon dosage (60mg, six tablets every 2.5 hours), which is already at the higher end of typical dosing, it's especially important that all treating doctors — including the radiotherapy team — are fully aware of the MG diagnosis and current medications.
Some important precautions include:
- Inform every specialist involved in radiotherapy care about the MG diagnosis
- Watch for infection signs and report them immediately, as infections can trigger a myasthenic crisis
- Monitor breathing carefully, as any respiratory changes need urgent medical attention
- Discuss any new medications prescribed during radiotherapy with a neurologist first
A myasthenic crisis is a serious risk if symptoms worsen, so having a clear action plan with the neurology team before and during radiotherapy is strongly recommended.
