Hi there, I have Waldenstroms, or what is a slow growing form of non Hodgkins B cell lymphoma. I received 4 Rituxan infusions, one week apart, in 2022. The only side effect I had was extreme fatigue for 3 months, tiredness for 3 more, and it slowly abated. I had such a messed up immune system prior to this! It truly saved my life! I pray you have a great oncologist you trust and can take the leap of faith to give it a try. Blessings and peace! Sue Hanna
