More information

  • Usage

    Nitrofurantoin, along with the branded versions Macrobid and Macrodantin, is an antibacterial agent. Macrobid is largely used for UTI treatment, specifically acute uncomplicated urinary tract infections (acute cystitis) caused by susceptible strains of Escherichia coli and Staphylococcus saprophyticus. Nitrofurantoin should only be used in the treatment or prevention of infections that are strongly suspected or proven to be caused by bacteria. As Macrobid, nitrofurantoin is found as a hard gelatin capsule shell containing nitrofurantoin 100 mg (nitrofurantoin macrocrystals and nitrofurantoin monohydrate). After administration, some nitrofurantoin can be found unchanged in the urine over 24 hours. Nitrofurantoin works by inactivating specific molecules such as ribosomal proteins in the target bacteria, impairing a number of metabolic processes. Additionally, bacterial resistance to nitrofurantoin is low. Macrobid is often prescribed as one 100mg capsule every 12 hours for seven days.

  • Nitrofurantoin – Side Effects

    Use of generic nitrofurantoin as well as branded versions of nitrofurantoin such as Macrobid and Macrodantin can result in various side effects. Concerns about nitrofurantoin side effects should be discussed with one’s pharmacist and medical provider before use. Side effects from nitrofurantoin use include diarrhea, nausea, headache, flatulence abdominal pain and bloody stool. People with a hypersensitivity or allergy to nitrofurantoin should not use this medication. Nitrofurantoin should not be used in the treatment of pyelonephritis or in the setting of anuria, oliguria, or renal impairment.

  • Cost Information

    While nitrofurantoin is only moderately affordable at roughly $1 per pill at most pharmacies, most nitrofurantoin courses are short which limits the total cost of the antibiotic. Additionally, the cost of nitrofurantoin is sometimes covered by insurance plans that cover medication costs. Nitrofurantoin coupons may be available for people who cannot afford the medication and need nitrofurantoin treatment. Farmington Drugs & Medical Supplies takes pride in offering the most cost efficient services and prescriptions to our patients.

  • Dosage

    Macrobid is available as 100 mg opaque black and yellow capsules.
