Warnings and cautions

Talk to your doctor before taking Duroferon if you:

Due to the risk of mouth sores and discoloration of the teeth, the tablets must not be sucked, chewed, or kept in the mouth, but must be swallowed whole with water. Talk to your doctor if you can not follow these instructions.

If you accidentally put a tablet in your throat, contact a doctor immediately as there is a risk of ulcers and narrowing of the trachea if the tablet enters the airways. Symptoms of this include persistent cough, coughing up of blood, and/or difficulty in breathing. The symptoms may come days or months after you put the tablet in your throat. Therefore, you must be examined quickly to check that the tablet has not damaged your airways.

Iron medicines can darken the stool.
