What are Rituximab Side Effects?

Rituximab’s common side effects include infusion reactions, infections, bruising and bleeding due to low platelet counts, and allergic reactions. Infusion reactions are among the most serious and common side effects, occurring in up to 90% of patients during the first infusion, and can range from mild to life-threatening symptoms such as fever, chills, and difficulty breathing. Additionally, infections can be severe and may include bacterial, viral, and fungal types; there’s also a significant risk of reactivating certain viruses like hepatitis B.

Common Rituximab Side Effects

• Infusion Reactions: Symptoms such as fever, chills, and breathing difficulties often occur during the first infusion. These reactions can be serious and require immediate medical attention.

• Infections: Rituximab can weaken the immune system, making patients more susceptible to various infections, including bacterial, viral, and fungal. Particular attention is needed to avoid reactivation of pre-existing infections, like hepatitis B.
