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.

Otrivine is a nasal decongestant which should only be used for temporary relief of symptoms may be continued. Escitalopram and inhalers and nebulizers may be continued. ...Read more

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

I was prescribed some antihistamines and over-the-counter decongestants.. is it serious?

Need More Info: It is probably not serious, but you cannot determine the seriousness of a disease just by knowing the recommended medications. I do not usually give my patients decongestants for long term use due to side effects like insomnia, agitation, elevated blood pressure, and heart rate. They are ok for short term use or when you are sick for a few days. ...Read more
