Product Details

Description

Nitrofurantoin (Macrobid) is an antibiotic to treat and prevent urinary tract infections (UTIs), including acute uncomplicated infections, recurrent infections, cystitis, and urethritis. Available in 50 and 100 mg tablets, Nitrofurantoin targets bacteria in the urinary tract effectively while minimizing systemic side effects. It is commonly prescribed for a 7-day course of treatment. This medication is well-tolerated, with a low risk of developing antibiotic resistance. Patients with kidney issues should use it cautiously, and it requires a prescription. Always follow the doctor’s instructions and store the medication out of the reach of children.

Uses and Benefits

Nitrofurantoin is used to treat:

  • Acute uncomplicated urinary tract infections (UTIs)
  • Recurrent urinary tract infections (prevention and treatment)
  • Lower urinary tract infections, such as cystitis (bladder infection) and urethritis (urethral infection).

Benefits of Nitrofurantoin

  • Nitrofurantoin for UTI provides effective treatment for urinary tract infections caused by common bacteria such as Escherichia coli, Enterococcus, and Klebsiella.
  • Specifically targets the urinary tract, helping to minimize effects on other parts of the body and reducing the risk of systemic side effects.
  • Antibiotics for cystitis nitrofurantoin, tend to cause less antibiotic resistance than some broad-spectrum antibiotics.
  • Effective for long-term prevention of recurrent urinary tract infections in select patients.
Dosage

Initial Dose: Typically 50-100 mg orally, four times a day for 7 days.

Adjustment: If needed, the dose may be adjusted based on renal function & severity of infection.

Maximum Dose: Generally, 100 mg every 6 hours, under medical supervision.

Usage Guide

When you order Nitrofurantoin online, consider the following administration instructions:

  • Always take Nitrofurantoin with food or milk to improve absorption and minimize the chance of stomach upset.
  • Swallow the tablet whole—do not break, chew, or crush it.
  • Try to take your doses at the same time each day, spaced evenly, to keep a steady amount of the drug in your body.
  • Finish the entire prescribed course, even if symptoms improve before the medication is done, to prevent infection from returning or becoming resistant.
How It Works

Nitrofurantoin is activated inside bacterial cells, where it damages DNA and essential proteins. This disrupts bacterial growth and survival, leading to their elimination. It concentrates in the urine, making it especially effective against urinary tract infections with a lower risk of resistance.

Side Effects

Common side effects of Nitrofurantoin:

  • Nausea or vomiting
  • Loss of appetite
  • Diarrhea
  • Headache
  • Dizziness
  • Mild rash or itching

Serious side effects (rare) of Nitrofurantoin:

  • Nerve pain
  • Lung reactions
  • Liver problems
  • Severe allergic reactions
  • Blood disorders
  • Severe diarrhea

Note: Contact your healthcare provider or doctor if you experience any serious symptoms.

Warnings

When you buy Nitrofurantoin medication online, it is important to become aware of certain warnings to ensure safe use and avoid complications:

  • Kidney problems: Nitrofurantoin should not be used by patients with significantly reduced kidney function, as it may not reach effective levels in the urine and can increase the risk of toxicity.
  • Lung issues: Rarely, Nitrofurantoin can cause lung inflammation or damage. If you notice a persistent cough, chest pain, or shortness of breath, stop taking the medication and contact your doctor.

Liver health: Monitor for symptoms of liver problems such as jaundice, dark urine, or severe abdominal pain. Seek prompt medical attention if these occur.

Safety Guide

If you plan to order Nitrofurantoin from Canada, consider the following safety precautions:

  • Consult Your Doctor First: Always get a prescription and medical advice before starting Nitrofurantoin. Self-medication can be dangerous.
  • Monitor Your Health: Attend all recommended medical appointments and tests to check for side effects and ensure the medication is working safely.
  • Pregnancy and breastfeeding: Nitrofurantoin for pregnancy is generally considered safe during the early stages under medical supervision. However, always consult your healthcare provider before use to ensure it’s the right choice for you. Nitrofurantoin passes into breast milk and may affect the nursing infant.
Missed Dose

If you miss a dose of Nitrofurantoin, take it as soon as you remember unless it's close to your next dose—then skip it. Never take two doses at once; stick to your regular schedule.

Overdose

Taking too much Nitrofurantoin can lead to serious health issues. If an overdose of this medication is suspected, seek immediate medical assessment or contact a Poison Help line at 1-800-222-1222.
