Understanding Common MG Treatment Side Effects

MG treatment may include medications, such as pyridostigmine (Mestinon), immunosuppressants, and therapies like plasma exchange or intravenous immunoglobulin (IVIG). While these treatments can be highly effective, they may come with side effects:

  • Gastrointestinal Distress: Nausea, diarrhea, or abdominal discomfort can occur with some medications.
  • Muscle Cramps: Pyridostigmine can lead to muscle cramps or twitching.
  • Weight Gain: Some treatments may cause weight gain as a side effect.
  • Fatigue: MG itself can cause fatigue, and certain treatments may exacerbate this symptom.
  • Immunosuppression: Immunosuppressive drugs can increase the risk of infections.
  • Injection Site Reactions: For patients receiving IVIG or other injections, localized pain or redness at the injection site is possible.

Open Communication with Your Healthcare Team

Effective management of side effects requires open communication with your healthcare team. Inform your doctor about any side effects you experience, even if they seem minor. They can offer guidance, adjust your treatment plan if necessary, or recommend alternative therapies to minimize side effects.

Remember that everyone's MG journey is unique, and what works best for one person may differ for another. By staying informed, proactive, and working closely with your healthcare team, you can better manage common side effects and improve your overall quality of life while living with Myasthenia Gravis.
