I am a doula, so I cannot give medical advice, nor did I take the medication when I was pregnant, but I can say that if your physician ordered it, and knows that you are pregnant it is likely safe. That said, if you want to get a second opinion on the safety you might speak with your pharmacist. Lastly, you can go the the website and educate yourself on the safety. The Nitrofurantn, or more commonly known as Macrobid is easily found at www.rxlist.com/cgi/generic/nitro25m_wcp.htm You can then decide what is best for you. Do keep in mind that sometimes the risks associated with the problem is greater than the risks associated with the treatment, and sometimes it is visa versa.
