Anticholinergic drugs and food: Increased absorption of nitrofurantoin. Magnesium salts: May reduce anti-infective action by decreasing absorption. Probenecid: May increase nitrofurantoin serum levels by reducing renal elimination.

Drug Assesment ::

 Assessment/Interventions

• Obtain patient history, including drug history and any known allergies.
• Obtain urine for culture and sensitivity prior to starting drug.
• Obtain results of CBC and other lab tests ordered by physician (ie, creatinine, electrolytes, alkaline phosphatase, bilirubin).
• Obtain vital signs. Monitor weight and I&O.
• Evaluate for signs of infection (ie, fever, chills, drainage, burning, frequency or hesitancy).
• Evaluate for dizziness, headaches, GI upset, skin changes, hearing, or vision changes.
• If patient exhibits shortness of breath, chest pain, continued fever, numbness, tingling, headache, dizziness, drowsiness, nystagmus, blood in urine, or signs of hemolysis, notify physician.

OVERDOSAGE: SIGNS & SYMPTOMS   Nausea, anorexia, vomiting, diarrhea
