Generic Furadantin Information

Introduction

Furadantin is an antibacterial medication used primarily to treat uncomplicated urinary‑tract infections (UTIs) caused by susceptible bacteria. The drug contains the active compound nitrofurantoin, which belongs to the nitrofuran class of antibiotics. In the United Kingdom, Furadantin (originally marketed by Pfizer) is prescribed when the causative organism is known to be sensitive, and when the infection is confined to the lower urinary tract. Its utility stems from high urinary concentrations and a low risk of promoting resistance in other body sites.

What is Furadantin?

Furadantin is a brand‑name formulation that delivers nitrofurantoin in immediate‑release tablets. Nitrofurantoin was first synthesised in the 195s and has been employed worldwide for the treatment of acute cystitis and uncomplicated pyelonephritis. The medication is classified as an antibacterial agent within the nitrofuran group. While Furadantin is the branded product, the same active compound is available under other well‑known names such as Macrobid, Macrodantin, and Nitrofurantoin‑macrocrystals. Our online pharmacy offers these generic alternatives at a cost comparable to the manufacturer’s price, providing a cost‑effective option for patients who need reliable therapy for urinary infections.

How Furadantin Works

Nitrofurantoin exerts its antibacterial effect through a multi‑step mechanism that targets bacterial metabolism. After oral administration, the drug is rapidly absorbed and concentrated in the urine, where it encounters pathogenic bacteria. Within the bacterial cell, nitrofurantoin undergoes enzymatic reduction by nitroreductases, producing reactive intermediates that damage DNA, ribosomal proteins, and other macromolecules. This damage impairs bacterial replication and leads to cell death. Because the drug is primarily excreted unchanged in the urine, therapeutic levels are achieved quickly—usually within 30 minutes—and are maintained throughout the dosing interval, providing effective eradication of susceptible organisms in the bladder and urethra.

Conditions Treated with Furadantin

• Uncomplicated cystitis (acute bladder infection) caused by Escherichia coli, Enterococcus faecalis, Staphylococcus saprophyticus and other nitrofurantoin‑susceptible strains. In the UK, cystitis accounts for up to 30 % of all primary‑care antibiotic prescriptions, highlighting the need for a reliable oral agent.
• Uncomplicated acute pyelonephritis in patients without renal impairment, when the infecting organism is known to be nitrofurantoin‑sensitive.
• Prophylaxis of recurrent urinary‑tract infections in adults who experience multiple episodes per year. Low‑dose nitrofurantoin taken once daily can reduce recurrence rates by 40–50 % in controlled studies.

Nitrofurantoin’s high urinary concentration, limited systemic exposure, and low propensity for cross‑resistance make it especially suited for these conditions. It is not indicated for complicated UTIs, prostatitis, or systemic infections that require broader tissue penetration.

Who is Furadantin For?

• Adults with an acute, uncomplicated bladder infection confirmed or strongly suspected to be caused by nitrofurantoin‑susceptible bacteria.
• Patients with normal renal function (creatinine clearance ≥ 60 mL/min). Adequate renal excretion is essential for achieving therapeutic urinary concentrations.
• Individuals seeking a short‑course oral therapy (typically 5–7 days) that minimizes disruption of gut flora and reduces the risk of Clostridioides difficile infection.
• Women of child‑bearing age who are not pregnant, as nitrofurantoin is contraindicated in the first trimester and near term due to potential fetal hemolysis.
• Patients requiring prophylactic treatment for recurrent UTIs, provided they have no history of nitrofurantoin hypersensitivity and maintain stable kidney function.

Furadantin is not appropriate for patients with severe renal impairment, known hypersensitivity to nitrofurans, or a history of pulmonary fibrosis related to nitrofurantoin use. Caution is also advised in individuals with glucose‑6‑phosphate dehydrogenase (G6PD) deficiency, as hemolytic anemia can occur.

Risks, Side Effects, and Interactions

Common

• Nausea, vomiting, or loss of appetite
• Diarrhoea or loose stools
• Headache or dizziness
• Mild urinary urgency or dysuria (usually transient)

Rare

• Peripheral neuropathy, presenting as tingling or numbness in the extremities, especially after prolonged use
• Hepatic enzyme elevation or transient hepatitis
• Pulmonary symptoms such as dry cough or mild shortness of breath without fever

Serious

• Acute or chronic pulmonary toxicity, which may manifest as interstitial pneumonitis, fibrosis, or severe dyspnoea; requires immediate medical attention
• Hemolytic anaemia, particularly in patients with G6PD deficiency, leading to jaundice, dark urine, and fatigue
• Severe allergic reactions, including anaphylaxis, characterised by rash, swelling, bronchospasm, or hypotension

Drug–Drug Interactions

• Antacids containing magnesium or aluminium can reduce nitrofurantoin absorption; separate dosing by at least two hours.
• Probenecid may increase nitrofurantoin plasma levels, raising the risk of toxicity.
• Vitamin C (ascorbic acid) in high doses can acidify urine and decrease drug efficacy.
• Warfarin: occasional reports of altered INR; monitor coagulation parameters when initiating or discontinuing nitrofurantoin.

Patients should disclose all concomitant medications, including over‑the‑counter supplements, to their healthcare provider before starting Furadantin.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing for acute cystitis: 100 mg nitrofurantoin macrocrystals taken twice daily (every 12 hours) for 5 days. Alternative immediate‑release 50 mg tablets are taken four times daily (every 6 hours).
• Prophylactic regimen: 50–100 mg once daily, preferably at bedtime, for a duration determined by the prescribing clinician.
• Renal adjustment: If creatinine clearance falls below 60 mL/min, the dose should be reduced or the drug avoided, as urinary concentrations become sub‑therapeutic.

Missed dose – Take the missed tablet as soon as remembered unless it is close to the time of the next scheduled dose; in that case, skip the missed dose and resume the regular schedule. Do not double‑dose.

Overdose – Symptoms may include nausea, vomiting, abdominal pain, and dizziness. If an overdose is suspected, seek immediate medical assistance or contact the UK National Poisons Information Service. Management is primarily supportive; activated charcoal may be considered if ingestion is recent.

Precautions – Take Furadantin with food or milk to lessen gastrointestinal irritation. Avoid alcohol, which can exacerbate nausea. Patients with chronic lung disease, diabetes, or a history of liver disease should be monitored closely for rare adverse events.

FAQ

• Is Furadantin available in both brand‑name and generic forms in the UK?
  Yes. The branded product is marketed as Furadantin, while the same active compound, nitrofurantoin, is widely available in generic tablets produced by several EU‑licensed manufacturers. Generic versions are typically less expensive and are therapeutically equivalent.

• Does Furadantin require any special storage conditions?
  The tablets should be stored at controlled room temperature (15‑30 °C), protected from moisture, direct sunlight, and excessive heat. No refrigeration is needed, but keep the container tightly closed to maintain stability.

• What does the packaging look like when ordered through an online service?
  Furadantin is supplied in blister packs of 10 or 20 tablets, each blister sealed with a foil backing. The outer box displays the product name, strength, batch number, expiry date, and a UK‑compliant safety label.

• Can I travel internationally with Furadantin tablets?
  Yes, provided you carry the medication in its original packaging, accompanied by a copy of the prescription or a doctor’s letter if requested by customs. Keeping the supply within personal use limits (typically a 30‑day supply) avoids import complications.

• Are there any differences in formulation between UK and US versions of nitrofurantoin?
  The UK market predominantly offers the macrocrystal formulation, whereas the US frequently uses the immediate‑release 50 mg tablet. Both contain the same active ingredient, but the macrocrystal version provides a longer urinary exposure, allowing twice‑daily dosing.

• What are the most common drug‑interaction warnings for nitrofurantoin?
  Antacids containing magnesium or aluminium, high‑dose vitamin C, and probenecid can interfere with absorption or increase plasma levels. Patients on warfarin should have their INR monitored when starting or stopping nitrofurantoin.

• Is nitrofurantoin safe for people with diabetes?
  Generally, yes, provided renal function is adequate. However, diabetic patients with reduced kidney filtration may require dose adjustment or an alternative antibiotic, as insufficient urinary concentrations can lead to treatment failure.

• How does nitrofurantoin compare to trimethoprim for uncomplicated cystitis?
  Nitrofurantoin achieves higher urinary concentrations and carries a lower risk of promoting resistance in gastrointestinal flora compared with trimethoprim. Clinical guidelines in the UK often recommend nitrofurantoin as first‑line therapy when the pathogen is susceptible.

• Can I use Furadantin as a long‑term preventive measure for recurrent UTIs?
  Low‑dose nitrofurantoin (50–100 mg once daily) is an established prophylactic regimen for patients with frequent recurrences, provided there is no history of pulmonary toxicity or renal impairment. Regular monitoring is advisable.

• What should I do if I experience a rash after taking Furadantin?
  A mild rash may be an allergic reaction; discontinue the medication and seek medical advice promptly. If the rash is accompanied by swelling, difficulty breathing, or fever, treat it as a potential anaphylactic reaction and obtain emergency care.

• Does personal import of Furadantin into the UK require a license?
  For a personal, non‑commercial supply of up to a three‑month quantity, a license is not required under UK law, provided the medication is for personal use and the import complies with the Medicines and Healthcare products Regulatory Agency (MHRA) guidelines.

• Are there any special considerations for elderly patients taking Furadantin?
  Elderly individuals often have reduced renal function; assessing creatinine clearance before prescribing is essential. Additionally, they may be more susceptible to peripheral neuropathy and pulmonary side effects, warranting closer clinical monitoring.
