Common side effects of Macrobid (Nitrofurantoin)

The medicine Macrobid is an antibiotic and therefore, a drug used to treat bacterial infections. It is used to treat urinary tract infections and infections of the bladder. Macrobid is the brand name used for the drug nitrofurantoin. It is able to fight against several types of bacteria such as E. Coli, Enterobacter cystitis, Enterococcus, Klebsiella, and Staphylococcus aureus.

Macrobid is an effective drug for preventing and treating acute cystitis which is a condition of an inflamed bladder due to the entrance of bacteria from the outside of the body and into the urinary tract through the urethra. It eventually begins to multiply and cause inflammation.

It is important; however that Nitrofurantoin is only used for bacterial infections as it would not work for other viral or fungal disease. 


How does Macrobid work?

It works by preventing bacterial growth. It does so by restricting and stopping the multiplication of bacteria. This keeps the bacteria from reproducing further as well as prevents the repair of their genetic material, i.e., DNA.

Macrobid should not be used to treat the common cold and flu and other similar viral infections because it will not be effective.

Using an antibiotic when not needed can reduce its effectiveness for future uses as the pathogen (disease-causing organism) may become resistant to it. As a result, they undergo mutations and introduce genes that will keep them unaffected by the action of the said antibiotic.
