Nasal congestion is a popular seasonal ailment, and nasal decongestant sprays can seem like an effective solution. But doctors are warning people to use the bottle sparingly.
Why all the caution? Nasal decongestant sprays can cause rhinitis medicamentosa, which is also known as rebound congestion. In short, this occurs when the medication squeezes blood from your nasal tissues. It seems like you can breathe again, but the relief wears off. Then blood, oxygen, and nutrients flood back into the area and patients can feel even more congested.
Rebound congestion can occur when people use nasal sprays constantly.
