Formula Information

A small arrow pointing down

Nitrofurantoin 75 mg Oral Capsules are a solid dosage form designed for the treatment of specific bacterial infections. These capsules consist of two halves, either made from gelatin or a vegetarian substitute, which encapsulate the active pharmaceutical ingredient, Nitrofurantoin. This encapsulation ensures that patients receive an exact dose of the medication, which is crucial for the efficacy and safety of the treatment. The capsules are intended to be swallowed whole, making them a convenient option for patients who may have difficulty with other forms of medication.

Nitrofurantoin is an antibiotic that is primarily used to treat urinary tract infections (UTIs) caused by susceptible strains of bacteria. It works by inhibiting the synthesis of bacterial DNA, RNA, and cell wall proteins, leading to the elimination of the infection-causing bacteria. It is particularly effective against E. coli, Enterococci, and certain strains of Staphylococci, among others. Nitrofurantoin is not effective against most strains of Proteus, Serratia, and Pseudomonas aeruginosa, which are also common causes of UTIs.

For optimal results, it is important that Nitrofurantoin 75 mg Oral Capsules be taken at evenly spaced intervals, ideally with food to enhance absorption and reduce the risk of gastrointestinal upset. The duration of the treatment should be strictly adhered to, even if symptoms improve before the course of therapy is complete, to prevent the development of antibiotic resistance. It is also important to note that Nitrofurantoin is not indicated for the treatment of pyelonephritis or perinephric abscesses, and it should not be used in patients with decreased renal function due to the risk of accumulation and potential toxicity.

Patients should be aware of potential side effects, which may include gastrointestinal discomfort, allergic reactions, and, in rare cases, pulmonary reactions. Prescribers should evaluate the patient's medical history, including any history of liver or lung disease, before initiating therapy with Nitrofurantoin. Regular monitoring of the patient's renal function and signs of any adverse reactions is also recommended during the course of treatment.

Drug Interactions

A small arrow pointing down

Nitrofurantoin is an antibiotic commonly used to treat and prevent urinary tract infections (UTIs). It works by inhibiting the synthesis of bacterial DNA, RNA, and cell wall proteins, leading to bacterial cell death. When considering the use of nitrofurantoin 75 mg oral capsules, it is important to be aware of potential drug interactions that may affect the efficacy of the treatment or cause adverse effects.

One significant interaction is with antacids containing magnesium trisilicate, which can decrease the absorption of nitrofurantoin, leading to reduced effectiveness. Patients should avoid taking antacids within a couple of hours of their nitrofurantoin dose. Similarly, drugs that increase urine pH, such as proton pump inhibitors, may reduce the drug's solubility and effectiveness. It is advisable to monitor the patient's urine pH and adjust the treatment as necessary.

Concomitant use of nitrofurantoin with quinolone antibiotics should be avoided as they may antagonize each other's antibacterial effects. Additionally, the concurrent use of drugs that can cause peripheral neuropathy, such as phenytoin, may increase the risk of this side effect when taken with nitrofurantoin. Patients with renal impairment should be closely monitored, as nitrofurantoin is contraindicated in patients with a creatinine clearance below 60 mL/min due to the increased risk of toxicity.

Patients on nitrofurantoin should also be cautious about using medications that can cause hemolysis, especially in those with a deficiency in glucose-6-phosphate dehydrogenase (G6PD). This is because nitrofurantoin can induce hemolysis in G6PD-deficient individuals. It is important to screen patients for G6PD deficiency before initiating treatment.

Furthermore, nitrofurantoin may interfere with the results of certain laboratory tests, including urinary glucose tests using copper reduction methods and urinary estriol levels in pregnant women. It is important to inform the laboratory personnel that you are taking nitrofurantoin if you are undergoing such tests.

Lastly, nitrofurantoin should not be used in patients at the end of their pregnancy, during labor and delivery, or in infants under one month of age due to the potential risk of hemolytic anemia in the newborn.

It is essential for patients and prescribers to be aware of these interactions to ensure the safe and effective use of nitrofurantoin. Always inform your healthcare provider about all the medications you are taking, including over-the-counter drugs, vitamins, and herbal supplements. If you have any questions or concerns about potential drug interactions with nitrofurantoin 75 mg oral capsules, please reach out to us at Bayview Pharmacy for further assistance.

How Does it Work

A small arrow pointing down

Nitrofurantoin is an antibiotic medication that is specifically used to treat and prevent urinary tract infections (UTIs) caused by certain bacteria. It is not effective against viral infections or most other types of bacterial infections. Nitrofurantoin works by entering the bacterial cells and damaging their genetic material (DNA). This damage inhibits the bacteria's ability to repair themselves or reproduce, ultimately leading to their death. The medication is particularly effective in the urinary tract because it is excreted primarily through the kidneys, which means it becomes concentrated in the urine and can act directly on the site of infection.

The 75 mg oral capsule formulation of nitrofurantoin provides a precise dosage of the active ingredient in a solid dosage form. The medication is enclosed within two gelatin or vegetarian shells, known as a capsule. These shells dissolve after the capsule is ingested, releasing the nitrofurantoin so it can be absorbed into the bloodstream and then filtered by the kidneys into the urine. The capsule form is designed to be easy to swallow and to ensure that the medication is delivered to the body in a controlled manner. This helps to maintain effective levels of the drug in the urine to combat the bacteria causing the infection.

For patients, it is important to take nitrofurantoin exactly as prescribed by their healthcare provider. The full course of the medication should be completed, even if symptoms improve before the medication is finished, to ensure that the infection is fully treated and to reduce the risk of developing antibiotic resistance. For prescribers, it is crucial to consider the patient's kidney function before prescribing nitrofurantoin, as impaired renal function can affect the drug's efficacy and safety. Additionally, nitrofurantoin should not be used for treating systemic infections or infections outside of the urinary tract.

If you have any questions about the nitrofurantoin 75 mg oral capsules or their use in treating urinary tract infections, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to provide you with the information and support you need to effectively manage UTIs with this formulation.

Other Uses

A small arrow pointing down

Nitrofurantoin 75 mg oral capsules are primarily used to treat and prevent urinary tract infections (UTIs) caused by susceptible strains of bacteria. They work by inhibiting the growth and multiplication of bacteria, helping to clear the infection. The formulation in solid dosage form ensures a consistent delivery of the active ingredient and facilitates adherence to the prescribed treatment regimen. However, beyond its use in UTIs, there are limited alternative applications for nitrofurantoin due to its specific mechanism of action and spectrum of activity.

While the primary indication of nitrofurantoin is for the management of UTIs, it is important to note that this medication is not effective for treating other types of infections, such as systemic or non-urinary tract infections, because its concentration levels in tissues other than the urine are quite low. Additionally, nitrofurantoin should not be used for the treatment of pyelonephritis or perinephric abscesses, as its penetration into renal tissues is suboptimal for these conditions. There are also special populations for whom nitrofurantoin may not be appropriate, such as patients with significant renal impairment, as its efficacy and safety have not been established in this group.

It is crucial for patients and prescribers to be aware of nitrofurantoin's limited scope of use and the potential for adverse reactions, such as gastrointestinal upset, pulmonary reactions, and hypersensitivity. Prescribers should ensure that their patients are thoroughly evaluated for any contraindications or potential drug interactions before beginning a course of nitrofurantoin. Also, patients should be informed about the importance of completing the prescribed duration to minimize resistance development and to fully eradicate the infection.

Before using nitrofurantoin 75 mg oral capsules for any off-label purpose, it is highly recommended that healthcare providers consult the most recent medical literature and clinical guidelines to ensure that the use is evidence-based and justified. Due to its narrow therapeutic window and the potential for serious side effects, any off-label use of nitrofurantoin should be considered cautiously. If you have any questions regarding the use of nitrofurantoin 75 mg oral capsules, or if you need information about treatment options for conditions other than UTIs, please reach out to us at Bayview Pharmacy. Our knowledgeable team of compounding pharmacists is always ready to provide guidance and information to support your healthcare decisions.
