A number of factors will affect the amount of Furadantin your healthcare provider prescribes, including your age and whether you are taking the antibiotic to treat or prevent a bladder infection. For treatment in adults, the recommended dosage of Furadantin is 50 to 100 mg four times daily, continued for at least three days after the infection has cleared. For children, dosing is determined by weight.
An Introduction to Dosing With FuradantinThe dose of Furadantin® (nitrofurantoin suspension) your healthcare provider recommends will vary, depending on various factors, such as:
- Your weight (for children)
- Your age
- Whether you are taking this medication to treat or to prevent bladder infections.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Furadantin Dosage for Children
The recommended dosage of Furadantin for treating urinary tract infections (UTIs) in children (age one month and older) is based on body weight. As a result, it is best if your child's healthcare provider weighs your child in order to determine an accurate dose, especially if your child has not been weighed recently.
When treating bladder infections, Furadantin is usually given four times a day. To prevent bladder infections in children, the medication is usually given once or twice a day.
Dose of Furadantin for AdultsThe recommended Furadantin dose for treating urinary tract infections in adults is 50 to 100 mg four times daily, continued for at least three days after the infection has cleared. For uncomplicated infections, the lower amount is usually recommended. For long-term treatment to prevent UTIs in adults, often just 50 or 100 mg once daily at bedtime is sufficient.
