Macrobid: Macrobid is the drug Nitrofurantoin in a special matrix so that the active drug is released over an extended period. This allows twice a day dosing for a drug that is normally given 4 times a day. Opening the tablet will destroy the time-release system. This will cause an overdose of the drug to enter the circulation and then there will be a period when no drug is released.Don't open the tablet. ...Read more

All at same time: It is safe to take a probiotic pill and a multivitamin during your course of treatment with Macrobid.

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. The odd bleeding could be implantation bleeding for a pregnancy or breakthrough bleeding from the effect of birth control on the pill. ...Read more

Furadantin (nitrofurantoin): This should not be taken chronically in this manner. It has numerous potentially very severe side-effects including interstitial pneumonia and others.

Not at all...: The usual dose of this med is 100mg 2x/day thus 200mg per day. I assume you are using it for a urinary tract infection. You u are you and healthy, which i assume you are based on the medication given, you should be fine. You can skip a later dose today, or even taking your later usual dose without trouble. So, rest assured...But just be carefull next time around...Good luck. ...Read more
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 moreSee 1 more doctor answer

As always, only take this (and any other) medication as directed by your physician. And don't save any for the next infection! ...Read more
