Furadantin is the brand name for a medication called Nitrofurantoin. It is an antibiotic primarily used to treat urinary tract infections (UTIs).

Nitrofurantoin is specifically effective against certain types of bacteria that commonly cause UTIs, such as Escherichia coli. It works by inhibiting the growth and reproduction of these bacteria, helping to clear the infection.

Medicine is available in the form of capsules and is typically taken orally. The dosage and duration of treatment will depend on the specific type and severity of the UTI, as well as individual factors such as the patient's age and kidney function.

It's important to note that Furadantin is primarily used to treat lower urinary tract infections and is not generally recommended for infections that have spread to the kidneys or bloodstream.

Typically, the recommended adult dosage of Furadantin for treating uncomplicated urinary tract infections is 50 to 100 milligrams (mg) four times a day, with the total daily dose not exceeding 400 mg.

For children, the dosage of this drug is usually based on their weight. The typical recommended dose for children is 5 to 7 milligrams per kilogram of body weight per day, divided into four equal doses.

It's essential to take Furadantin with food to improve its absorption and reduce the risk of stomach upset. It is also important to complete the full course of treatment, even if symptoms improve before the medication is finished.

There are also signs of contraindications as some websites list down. These include signs like Anuria, oliguria and some impairment to the renal function. Since renal functions are disturbed, such patients possess increase risk of toxicity flowing their blood and would require additional treatments.

Furadantin can interact with certain medications, substances, and conditions. Here are some potential interactions to be aware of:

  1. Antacids containing magnesium trisilicate: These antacids can reduce the absorption of Nitrofurantoin. It is recommended to avoid taking them at the same time as Furadantin.
  2. Probenecid: Probenecid, a medication used to treat gout, can increase the levels of Furadantin in the body.
  3. Oral contraceptives: Nitrofurantoin may reduce the effectiveness of oral contraceptives (birth control pills). It is important to use an additional form of contraception, such as condoms, while taking Furadantin and for a short period afterward.
  4. Other antibiotics: Concurrent use of Furadantin with certain antibiotics, such as sulfa drugs or quinolones, may increase the risk of side effects.
  5. Diabetes medications: Nitrofurantoin can affect blood sugar levels and may require adjustments in the dosage of diabetes medications.
  6. Other medical conditions: It is important to disclose any medical conditions you have, such as kidney disease, liver disease, or a history of lung problems. Furadantin may require dosage adjustments or additional monitoring in these cases.


Here are some important warnings associated with the use of Furadantin:

  1. Allergic reactions: Some individuals may experience allergic reactions to Furadantin. If you develop symptoms like rash, itching, swelling, severe dizziness, or difficulty breathing, seek immediate medical attention.
  2. Lung problems: Furadantin has been associated with a rare but serious lung condition called pulmonary fibrosis.
  3. Liver problems: Furadantin can rarely cause liver damage. If you notice symptoms such as yellowing of the skin or eyes (jaundice), dark urine, persistent nausea or vomiting, or abdominal pain, these may indicate liver problems.
  4. Peripheral neuropathy: Furadantin may rarely cause peripheral neuropathy, a condition characterized by numbness, tingling, or pain in the hands or feet.
  5. G6PD deficiency: Individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency should exercise caution while taking Furadantin, as it can trigger hemolysis (breakdown of red blood cells) in these individuals.
  6. Kidney function: Furadantin is primarily eliminated through the kidneys.
  7. Pregnancy and breastfeeding: Nitrofurantoin should be used with caution during pregnancy, especially near term (38 to 42 weeks), as it may cause a certain blood disorder called hemolytic anemia in newborns. It is generally not recommended during breastfeeding, as small amounts may be excreted in breast milk.
  8. Resistance and effectiveness: Like all antibiotics, the inappropriate use of Furadantin can contribute to the development of bacterial resistance. It is important to take the medication exactly as prescribed and complete the full course of treatment to maximize its effectiveness.

Furadantin and Alcohol

It is generally recommended to avoid consuming alcohol while taking Nitrofurantoin. Drinking alcohol while on Furadantin can increase the risk of certain side effects and may reduce the effectiveness of the medication.

Alcohol can potentially worsen the side effects associated with Furadantin, such as dizziness, drowsiness, and nausea. It can also put additional strain on the liver, which is responsible for metabolizing both alcohol and the medication. Combining alcohol with Furadantin may increase the risk of liver damage or other adverse effects on the body.

Moreover, alcohol can interfere with the body's immune response, potentially reducing the body's ability to fight off the infection being treated with Furadantin.

To ensure the best possible outcomes and minimize potential risks, it is advisable to refrain from consuming alcohol while taking Furadantin.
