What is Macrobid and when is it used?
Macrobid is one of the trade marks for the medicinal substance Nitrofurantoin. It is a broad-spectrum bactericidal, antibacterial medication, a synthetic antimicrobial derivative of nitrofuran.
The medication renders a bacteriostatic effect (stops the growth of bacteria), but can also act bactericidal (killing bacteria) depending on the concentration and sensitivity of microorganisms. It disrupts the synthesis of DNA, RNA and protein in bacterial cells. The resistance of microorganisms to the formulation is rare.
When can you use Macrobid?
You can buy Macrobid for primary or relapsing urinary tract (cystitis, urethritis, pyelitis, pyelonephritis,), including caused by enterococci and Staphylococcus aureus, Escherichia coli and some strains of Klebsiella, Enterobacter and Proteus. It can be also used as a prevention of infections during urological operations or invasive procedures, for instance, catheterization.

If you buy generic Macrobid without having the instructions from your doctor how to use it, you can follow the general guide:
The pills are taken by 50-100 mg 4 times a day; children are prescribed 5-7 mg/kg body weight per day taken in 4 divided doses. When prescribing a long course of therapy, the dose of nitrofurantoin must be reduced; adults are usually prescribed 50-100 mg once a day (in the evening), children - 1 mg / kg in 1-2 doses.

The medication must be cautiously used in impaired renal function, low hemoglobin, diabetes, electrolyte imbalance, vitamin B deficiency or severe chronic diseases due to the elevated risk of peripheral neuropathy; in the appearance of the first symptoms of neuropathy must be stopped immediately.

Can Macrobid be used with other medicines?
Be careful when you buy generic Nitrofurantoin if you already take any other medicines:
- Uricosuric agents, such as probenecid and sulfinpyrazone, can reduce the excretion of Nitrofurantoin in the urine, reducing its effective concentration in the urinary tract, and increase its concentration in blood plasma, increasing its toxicity.
- Magnesium trisilicate with simultaneous use reduces the speed and extent of absorption of nitrofurantoin.
