Some people may experience reactivation of dormant viral infections like hepatitis B, which is why screening is done before treatment. Regarding effectiveness timeline:
- You may not notice improvements until 3 months or more after starting treatment
- Once working, improvements can last 6-12 months or longer
- Treatment involves two initial infusions given two weeks apart
- Each infusion takes 3-4 hours
- Your doctor may recommend repeating treatments every 6 months
Before each infusion, you'll receive corticosteroids to help prevent side effects.
