Nitrofurantoin Macrocrystals are used to treat or prevent urinary tract infections (UTIs) in patients of all ages. The medication comes in tablets, typically taken 4 times per day.

Though a potent antibiotic, Nitrofurantoin Macrocrystals concentrate in the urine, meaning it's not particularly effective at fighting bacteria elsewhere in the body, including the kidneys. Patients should buy Nitrofurantoin Macrocrystals to treat bacterial infections of the bladder or urinary tract only.

Patients most commonly buy Nitrofurantoin Macrocrystals by the brand names Macrobid or Macrodantin. It is also widely available as a generic, with the active ingredient sometimes labelled Nitrofurantoin Macrocrystals and sometimes simply Nitrofurantoin.

Resistant Bacteria

There are some bacteria out there resistant to Nitrofurantoin Macrocrystals, but it's not nearly as widespread a problem as with other antibiotics used to treat UTIs. In fact resistance is such a problem among other antibiotics that in the USA and EU Nitrofurantoin Macrocrystals are often the first-line choice for UTIs, at least for the time being.

Patients who buy Nitrofurantoin Macrocrystals should be sure to fully complete each course of treatment to avoid contributing to resistant bacteria. Treatment should generally continue for three full days following the last symptoms of the condition; this ensures any lingering bacteria are destroyed.

Relief from UTIs

Patients most commonly buy Nitrofurantoin Macrocrystals to treat bacterial infections of the bladder or urinary tract. It is effective against all common bacteria that cause such infections, including E. coli and several Staphylococcus and Streptococcus species, provided the particular variety of bacteria has not developed resistance.

In otherwise healthy adults:

• 50 to 100 mg should be taken four times per day, spaced apart as evenly as possible.
• Food or milk should be consumed with each dose to aid with absorption.
• Treatment should continue for at least one week.
• Treatment should continue for three days after the infection has cleared up.

In younger patients dosage depends on weight; as a general rule, 5 mg of Nitrofurantoin Macrocrystals per kg of weight per day. As with adults, the total dose should be divided into four smaller doses, taken at evenly-spaced intervals throughout the day.

Dosage depends on both the severity of the infection and patient weight. Likewise duration of treatment may vary; one week is sufficient in most cases, but sometimes it will take longer. Some improvement is usually noticed within a day or two of starting treatment, with significant alleviation of pain, discomfort, and other UTI symptoms.

If there is little or no improvement after a week of taking Nitrofurantoin Macrocrystals a doctor should be consulted. It may not be a bacterial infection, or the bacteria may have developed resistance.

Preventing UTIs

Patients who are at high risk of acquiring a UTI or who are simply prone to them may also buy Nitrofurantoin Macrocrystals to prevent them from developing in the first place.

Treatment is simple:

• Adults should take 50 to 100 mg once per day, typically at bedtime.
• Children should be given 1 mg per kg of weight per day, at bedtime.
• Food or milk should be consumed with each dose to aid with absorption.
• Treatment may continue for as long as necessary, but there are risks associated with long-term use.

Though rare---about 1 in 5000 patients---some individuals experience pulmonary (lung) complications if taking Nitrofurantoin Macrocrystals long-term. The risk is slightly higher in women and slightly higher in elderly patients. Symptoms may not be noticeable until serious damage has been done. Patients using Nitrofurantoin Macrocrystals for more than a couple weeks should be alert for any change in lung function; unexplained frequent coughing, chest pain, difficulty breathing, or any other changes, and should attend regular doctor checkups to monitor for developing complications.
