Rituximab and hyaluronidase human injection has caused severe, life-threatening skin and mouth reactions. If you experience any of the following symptoms, tell your doctor immediately: painful sores or ulcers on the skin, lips, or mouth; blisters; rash; or peeling skin.
You may already be infected with hepatitis B (a virus that infects the liver and may cause severe liver damage) but not have any symptoms of the disease. In this case, receiving rituximab and hyaluronidase human injection may increase the risk that your infection will become more serious or life-threatening and you will develop symptoms. Tell your doctor if you have or ever had a severe infection, including hepatitis B virus infection. Your doctor will order a blood test to see if you have an inactive hepatitis B infection. If necessary, your doctor may give you medication to treat this infection before and during your treatment with rituximab and hyaluronidase human injection. Your doctor will also monitor you for signs of hepatitis B infection during and for several months after your treatment. If you experience any of the following symptoms during or after your treatment, call your doctor immediately: excessive tiredness, yellowing of the skin or eyes, loss of appetite, nausea or vomiting, muscle aches, stomach pain, or dark urine.

If you experience any of the following symptoms, call your doctor immediately: new or sudden changes in thinking or confusion; difficulty talking or walking; loss of balance; loss of strength; new or sudden changes in vision; or any other unusual symptoms that develop suddenly.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to rituximab and hyaluronidase human injection.
