For patients with rhinitis, nasal spray can be said to be a necessary "magic weapon", gently spraying for ten seconds to clear. On social media platforms, there are 190 million views on topics related to rhinitis, and nasal spray is also on the list. As a common way to treat rhinitis, nasal spray has a wide audience, but the reporter noticed that many people have a question, "There are hormones in rhinitis spray, can it be used for a long time. Everyone has some concerns about hormones, thinking that they have side effects, but in reality, nasal spray hormones are very safe. "Because the dose sprayed into the nasal cavity is calculated in micrograms, compared to oral administration and injections (in milligrams), it is actually one thousandth of the dose. Nasal sprays sprayed into the nasal cavity in micrograms have local effects, but rarely enter the whole body. Overall, the dose is within a very safe range, and it is safe to use it for a longer period of time, such as three months to six months." Nowadays, there are many brands of nasal sprays on the market, with many claims of "good use", "intelligence tax", and "never use", which have different red and black lists in the minds of users. The reporter found that some people who have been "planted" will purchase medicine on their own; Some people just casually place orders and buy medicine bottles that look similar; Some people like to buy medicine online, but they are not clear about the type and dosage of medication, and using the wrong medication can lead to drug-induced rhinitis. Netizen "Xiaoqi Qiqi" once capsized because of this. After using a Japanese brand of nasal spray for a long time, she urgently reminded her not to use it again! She shared firsthand, "I have been using it since 2018, and it is always available at the company, home, and bedside. I have used no less than twenty bottles and spray them every day. If I don't spray, my nose will become stuffy and uncomfortable." However, after seeking medical attention, she was informed that this nasal spray has a vasoconstricting effect, is dependent, and cannot be used anymore. Nasal spray decongestants can cause dependence. Currently, steroid nasal sprays are the most commonly used in clinical practice, while antihistamine nasal sprays generally do not have dependence. However, it should be noted that nasal spray decongestants are a type of vasoconstrictor that can cause dependency. "Some people who have a cold may experience a 'cement sealed nose' and may also use this spray. When sprayed, the blood vessels in the nasal mucosa contract, and the blocked nose is immediately cleared. However, it is generally recommended to use this spray for 5 to 7 days for colds, 1 to 2 weeks for allergic rhinitis, and no more than 2 weeks.". If used continuously after two weeks, or self dosed, with a particularly high frequency of use, over time it may develop dependence and even develop into drug-induced rhinitis. "Nowadays, many people tend to purchase medication on their own, even online shopping. Without the guidance of pharmacists and doctors, improper dosage and method of use can easily lead to problems." Cheng Lei said, "In fact, if used properly, the medication itself is safe. However, indiscriminate use and abuse can be counterproductive." Experts also remind that regardless of the type of nasal spray, if symptoms cannot be clearly controlled within two weeks of use, it is necessary to go to the hospital for specialized examination in a timely manner. If necessary, allergen testing can be performed. Spray
