Had a UTI and felt some pain in my kidneys, took macrobid. On the pill, had strange light period after. Negative preg. tests. What affected my period?

Antibiotics: I usually advise patient on the pill that if they take antibiotics, they should use back up birth control. Some anitbiotics lower the effectiveness of your pill.

Furadantin (nitrofurantoin): This should not be taken chronically in this manner. It has numerous potentially very severe side-effects including interstitial pneumonia and others. It is a close cousin of the drug Dilantin which has full texts written about the toxicities. Would stop this now and discuss with the doctor who ordered it. ...Read more

Safe to drink ensure on macrobid?

Safe to drink ensure on macrobid?

Ensure not that safe: It is as safe to drink Ensure while on Macrobid as at any time but I do not recommend Ensure; the first 3 ingredients are water, corn maltodextrin and sugar. It has canola and corn oil and soy that are almost certainly genetically modified and thus best avoided. If you want a nutritious drink I advise going to the health food store and getting a good quality non-gmo protein powder with vitamins. ...Read more
