Use a saline spray
Saline sprays are an effective alternative to nasal decongestant sprays. Saline sprays [6] help relieve congestion in the sinuses without the potential side effects of decongestant sprays. This salt solution helps thin mucus that may be blocking the sinuses and frees up the passages. Saline sprays also decrease inflammation of blood vessels that often accompanies sinus congestion.
You can purchase saline sprays over-the-counter or online. Some saline sprays include decongestants. You should avoid using these unless regular sinus sprays are ineffective. Speak to your doctor or pharmacist about any interactions this may have with other medications you are taking.
