How long does it take to take nitrofurantoin?

Nitrofurantoin is only available as an oral medication. Nitrofurantoin’s optimal dosing remains unknown since its use was approved before modern requirements for rigorous methods for drug development. Current Infectious Disease Society of America guidelines recommend nitrofurantoin monohydrate/macrocrystals dosage to be 100 mg twice daily for 5 days for the treatment of lower urinary tract infections. A 7-day course of 100 mg twice daily is also considered acceptable. Courses of less than 5 days are shown to be less effective and are no longer recommended. Dosing for long-term prophylaxis of urinary tract infections is 50 mg to 100 mg once daily at bedtime. There are no dosing adjustments for renal impairment as the drug is contraindicated in renal impaired patients.

How does Nitrofurantoin work?

Nitrofurantoin uses several mechanisms to achieve an antimicrobial effect. Nitrofurantoin is taken up by bacterial intracellular nitroreductases to produce the active form of the drug via reduction of the nitro group. Intermediate metabolites that result from this reduction then bind to bacterial ribosomes and inhibit bacterial enzymes involved in the synthesis of DNA, RNA, cell wall protein synthesis, and other metabolic enzymes.

What are the effects of nitrofurantoin?

More severe reactions to nitrofurantoin exist. The most well known severe reaction is pulmonary toxicity. Pulmonary toxicity caused by nitrofurantoin can be categorized into acute, subacute, and chronic pulmonary reactions. The acute pulmonary reaction syndrome is characterized by sudden onset of fever, chills, cough, myalgia, and dyspnea. Sub-acute pulmonary reactions also occur and are characterized by persistent dry cough, dyspnea, and fever. This chronic, pulmonary reaction is associated with the insidious onset of persistent dry cough and dyspnea. Acute, subacute, and chronic pulmonary toxicity are reversible with immediate cessation of the drug. This effect remains uncommon, with one study showing the calculated frequency for all pulmonary reactions were only present in 0.001% of nitrofurantoin courses. Other rare adverse effects include hepatic reactions such as cholestatic jaundice, hepatitis, and hepatic necrosis. The drug should be ceased immediately in these cases. Peripheral neuropathy is another known rare adverse effect, and is mostly associated with prolonged use in patients with poor renal function.

Is nitrofurantoin absorbed in the gastrointestinal tract?

Bioavailability of nitrofurantoin is considered to be 80% in healthy patients. Nitrofurantoin is well absorbed in the gastrointestinal tract with most absorption occurring in the proximal small bowel. Studies have shown that therapeutic urinary concentrations of the drug are increased if nitrofurantoin is taken with food. Serum concentrations are typically undetectable, although may increase in patients with severe renal failure. Nitrofurantoin only achieves therapeutically active concentrations in the lower urinary tract.

Is nitrofurantoin safe for oral use?

The drug has been around for decades and is relatively safe. Its lung toxicity is overstated and is infact very rare. The drug is only available for oral use.

Can you take nitrofurantoin with anuria?

Patients with anuria, oliguria, or significant impairment of renal function (defined as creatinine clearance [CrCl] of less than 60 mL/min or clinically significant raised serum creatinine) should not take nitrofurantoin. Of noted, the limit of CrCl less than 60 mL/minute has been challenged in the literature as there is limited data for this cutoff; some studies show that an alternative creatinine clearance threshold may be considered. A retrospective chart review suggests that a cutoff of CrCl less than 40 ml/min would be more appropriate.
