Macpac Patient Information

Patients should be advised to take Macrobid with food (ideally breakfast and dinner) to further enhance tolerance and improve drug absorption. Patients should be instructed to complete the full course of therapy; however, they should be advised to contact their physician if any unusual symptoms occur during therapy.

Patients should be advised not to use antacid preparations containing magnesium trisilicate while taking Macrobid.

Patients should be counseled that antibacterial drugs including Macrobid should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Macrobid is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Macrobid or other antibacterial drugs in the future.

Macpac Organisms Affected

Gram negative and some gram positive bacteria
