I've taken antibiotic used nasopure and now I'm taking mucinex.d and nothing is helping and I still smell an order and have a bad taste what can it be?

Hello. Than you for posting.

Bad breath from illness or post-nasal drip is due to the bacteria which are attracted to the mucus and phlegm. Just like with human food, the bacteria feed and emit foul-smelling compounds from the amino acids within the mucus and phlegm. Unfortunately, nasal decongestants may help the drip, but can also increase the bad breath. If the decongestant is too strong, it will dry out the mouth. A dry mouth produces its own conditions for bad breath. In many cases, the mucus returns with the same potency when the decongestant usage stops. Decongestants should be used in temporary situations such as during a cold or allergy season. Waiting for the illness to be over, should resolve the order and taste problem for most people. Good oral hygiene is important during illness and of course, should be practiced thereafter. Some antibiotics can cause a bad taste in the mouth as well.
