Can medications cause bad breath?
A question posed at chron.com asks how medications can contribute to bad breath.
Some drugs can cause your mouth to dry, creating conditions that the odor-causing germs thrive in.
Antibiotics can ease severe halitosis, if the problem is bacteria in the stomach (Helicobacter pylori). Out of control diabetes can also cause a distinctive bad breath. Heart medicines with nitrates sometimes contribute, but are crucial and should not be stopped.
