Is it safe to take an antihistamine and a decongestant everyday to help combat chronic sinus infections?

Is it safe to take an antihistamine and a decongestant everyday to help combat chronic sinus infections?

In general, yes: Improving nasal function will decrease the incidence and severity of sinusitis. If you are allergic and congested then a combination of an antihistamine decongestant can be of help.

Okay: A number of medications should be discontinued prior to allergy skin testing. Steroid nasal sprays like nasonex may be continued.

Dry eyes. Can't take decongestant or antihistamine for sinus infection. Will Sinoclear serve the purpose of unclogging sinus n post nasal drip?

Dry eyes. Can't take decongestant or antihistamine for sinus infection. Will Sinoclear serve the purpose of unclogging sinus n post nasal drip?

Decongestant?: Although antihistamine dries up the nose, decongestant does not. If the decongestant action is needed for just a few days, you may try Afrin nasal spray 2x daily for up to 5 days. A nasal steroid will likely work better if you have allergies. ...Read more
