Nitrofurantoin 100mg

Nitrofurantoin 100mg Uses

Nitrofurantoin 100mg is prescribed to:

• Treat urinary tract infections (UTIs) caused by specific bacteria.
• Prevent recurrent UTIs in patients with a history of frequent infections.
• Provide symptomatic relief from UTI-related discomfort.

How Does Nitrofurantoin 100mg Work

Nitrofurantoin works by inhibiting bacterial enzymes involved in the synthesis of proteins, nucleic acids, and cell walls, effectively halting the growth of bacteria. By targeting the bacteria that cause urinary tract infections, Nitrofurantoin helps to clear the infection and reduce inflammation in the urinary system.

Nitrofurantoin specifically concentrates in the urine, where it is most effective in treating infections of the bladder and kidneys.

How to Use Nitrofurantoin 100mg

• Dosage: The usual dosage for the treatment of UTIs is one Nitrofurantoin 100mg capsule taken twice daily, as prescribed by your healthcare provider.
• Administration: Swallow the capsule whole with a glass of water. Do not chew or crush the capsule.
• Frequency: Take the medication at the same times each day for optimal effectiveness.
• Duration: The duration of treatment is typically 5 to 7 days, depending on the severity of the infection and your doctor’s recommendation. For long-term prevention, your doctor will determine the appropriate dosing schedule.

Important Notes

• Always complete the full course of treatment, even if symptoms improve before the prescribed end date.
• Nitrofurantoin is most effective when taken with food to enhance absorption and reduce the risk of gastrointestinal upset.
