Classification: Urinary germicide

See Also: See also Anti-Infectives .

Action/Kinetics: Interferes with bacterial carbohydrate metabolism by inhibiting acetyl coenzyme A; also interferes with bacterial cell wall synthesis. Bacteriostatic at low concentrations and bactericidal at high concentrations. Tablets are readily absorbed from the GI tract; bioavailability is increased by food. t 1/2: 20 min (60 min in anephric clients). Urine levels: 50-250 mcg/mL. If the C CR is less than 40 mL/min, urine antibacterial levels are inadequate, with the subsequent higher blood levels increasing the possibility of toxicity. Antibacterial activity is best in an acid urine. From 30% to 50% excreted unchanged in the urine. Nitrofurantoin macrocrystals (Macrodantin) are available; this preparation maintains effectiveness while decreasing GI distress.

Uses: UTIs due to susceptible strains of Escherichia coli, Staphylococcus aureus (not for treatment of pyelonephritis or perinephric abscesses), enterococci, and certain strains of Enterobacter and Klebsiella.

Contraindications: Anuria, oliguria, and clients with impaired renal function (C CR below 40 mL/min); pregnant women, especially near term; infants less than 1 month of age; and lactation.

Special Concerns: Use with extreme caution in anemia, diabetes, electrolyte imbalance, avitaminosis B, or a debilitating disease. Safety during lactation has not been established.

Side Effects: Nitrofurantoin is a potentially toxic drug with many side effects. GI: N&V, anorexia, diarrhea, abdominal pain, parotitis, pancreatitis. CNS: Headache, dizziness, vertigo, drowsiness, nystagmus, confusion, depression, euphoria, psychotic reactions (rare). Hematologic: Leukopenia, thrombocytopenia, eosinophilia, megaloblastic anemia, agranulocytosis granulocytopenia, hemolytic anemia (especially in clients with G6PD deficiency). Allergic: Drug fever, skin rashes, pruritus, urticaria, angioedema, exfoliative dermatitis, erythema multiforme (rarely, Stevens-Johnson syndrome), anaphylaxis arthralgia, myalgia, chills, sialadenitis, asthma symptoms in susceptible clients; maculopapular, erythematous, or eczematous eruption. Pulmonary: Sudden onset of dyspnea, cough, chest pain, fever and chills; pulmonary infiltration with consolidation or pleural effusion on x-ray, elevated ESR, eosinophilia. After subacute or chronic use: dyspnea, nonproductive cough, malaise, interstitial pneumonitis. Permanent impairment of pulmonary function with chronic therapy. A lupus-like syndrome associated with pulmonary reactions. Hepatic: Hepatitis, cholestatic jaundice, chronic active hepatitis, hepatic necrosis (rare). CV: Benign intracranial hypertension, changes in ECG, collapse, cyanosis. Miscellaneous: Peripheral neuropathy, asthenia, alopecia, superinfections of the GU tract, muscle pain.

Laboratory Test Alterations: AST, ALT, serum phosphorus. Hemoglobin.

Overdose Management: Symptoms: Vomiting (most common). Treatment: Induce emesis. High fluid intake to promote urinary excretion. The drug is dialyzable.

Drug Interactions: Acetazolamide / Nitrofurantoin effect R/T urine alkalinity produced by acetazolamide Antacids, oral / Nitrofurantoin effect R/T GI tract absorption Anticholinergic drugs / Nitrofurantoin effect R/T stomach absorption Magnesium trisilicate / Nitrofurantoin absorption from GI tract Nalidixic acid / Effect of nalidixic acid Probenecid / High doses secretion of nitrofurantoin toxicity Sodium bicarbonate / Nitrofurantoin effect R/T urine alkalinity produced by sodium bicarbonate

How Supplied: Capsule: 25 mg, 50 mg, 100 mg; Suspension: 25 mg/5 mL (Nitrofurantoin)

Virtue evaluation is one other way that fundamental prices are frequently changed. The sort of virtue evaluation QuotesChimp are almost certainly to encounter is expertise evaluation. In expertise evaluation, variables which make someone a favourite, sub standard, or typical threat (e.g., an individual's driving report in vehicle insurance policy) are investigated along with the premium is fixed upwards, down, or never, as the underwriter deems suitable.

I had almost all the side effects of this drug. My doctor prescribed another antibiotic in addition to this one. It wasn't until I read this article that I realized that it was causing my symptoms for four days.
