Interactions between your drugs
Applies to: ampicillin and Folex PFS (methotrexate)
Talk to your doctor before using methotrexate together with ampicillin. Medications like ampicillin, 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.
Drug and food interactions
Applies to: ampicillin
You may experience reduced absorption of ampicillin in the presence of food. The effectiveness of the antibiotic may be reduced. Ampicillin should be administered one hour before or two hours after meals. This will make it easier for your body to absorb the medication. Penicillin V and amoxicillin are not affected by food and may be given without regard to meals.
Applies to: Folex PFS (methotrexate)
Caffeine may reduce the effectiveness of methotrexate in the treatment of arthritis.
