If you are looking for a product or treatment that can both treat your bad breath and post nasal drip at the same time, you have come to the right place.
First of all, I think I should mention a few things about antihistamines. Having suffered from rhinitis (runny nose) due to allergies for a long time – which caused me to suffer from post nasal drip as a consequence – and having used antihistamines all along, I would totally recommend you stop using them as soon as possible.
Why? First, they are only ever going to treat the symptoms of your sinus problems; they will never attack the condition from the root. Secondly, antihistamines will usually dry your mouth (a lot!), which will exacerbate your bad breath even more. Yes, in case you did not know it, bad breath and post nasal drip usually come together. This is because all that mucous build-up is a perfect environment for anaerobic bacteria (germs responsible for bad breath).
What should you use instead? Answering this is a no brainer for me now: a pulsating sinus irrigation system. This device, if used regularly, will not only completely eliminate all your post nasal drip and sinus congestion symptoms, but it will also be very effective at treating your bad breath problem from the root (that is, by eliminating all that mucous!) without drying your mouth.
Pulsating sinus irrigation systems have been shown to stimulate nasal cillia and improve nasal function after just a few uses. Therefore, effectively treating sinus problems from the root. They are over 100 times more effective than non-pulsating sinus irrigation systems so I would strongly advice you get yourself a pulsating one.
Bad breath and post nasal drip can be successfully treated at home. Make sure you ditch your antihistamines and switch to one of the most effective treatments available today. Find a pulsating sinus irrigation system review here.
