Applies to: Methotrexate LPF Sodium (methotrexate) and Bicillin C-R 900 / 300 (penicillin g benzathine / procaine penicillin)

Talk to your doctor before using methotrexate together with procaine penicillin. Medications like procaine penicillin, especially when given at high dosages for serious infections, can sometimes increase the blood levels and effects of methotrexate. You may have increased side effects such as nausea, vomiting, mouth ulcers, and low blood cell counts, which can make you more likely to develop anemia, bleeding problems, and infections. Contact your doctor if you experience potential signs and symptoms of these conditions such as paleness, fatigue, dizziness, fainting, unusual bleeding or bruising, fever, chills, sore throat, body aches, or other flu-like symptoms. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
