- › You are at higher risk of having toxic symptoms because of too much Otrexup (Methotrexate) in your blood if you have kidney disease, or if you have fluid in the abdomen (ascites) or in the lungs (pleural effusion). Your doctor will monitor your body's reaction to Otrexup (Methotrexate) very closely if they decide you need to be on Otrexup (Methotrexate).
- › Tumor lysis syndrome happens when cancer cells are broken down very quickly and damage the kidneys. The damage can be so bad that people need dialysis. If you're taking Otrexup (Methotrexate) to treat cancer, your doctor can give you medicines and take measures to prevent this reaction.
