It is rarely discussed, but a long list of common medications can contribute to bad breath—usually as a side effect of reduced saliva production.
Why it happens: Many medications—including antihistamines, decongestants, antidepressants, blood pressure medications, and some painkillers—list dry mouth as a known side effect. Since saliva is the mouth's primary defense against odor-causing bacteria, anything that reduces its amount can indirectly worsen breath, even if the medication has nothing directly to do with oral health.
How to tell if this is the cause: If bad breath started or worsened in conjunction with a new prescription, and you also notice increased thirst or a sticky feeling in your mouth, medication-related dry mouth is a reasonable explanation to bring up with your doctor or pharmacist.
The role of Frelopop: In this case, the medication usually does not need to change, but the side effect of dryness is very manageable on a daily basis. Frelopop's xylitol and probiotic formula is designed to combat this very type of persistent dryness, to be used as often as needed throughout the day.
