Can expired rhinitis medication still be used?

Nasal medications that have expired generally should not be used.

Rhinitis is usually caused by inflammatory changes in the nasal mucosa, commonly leading to symptoms such as nasal congestion and increased secretions blocking the nasal passages. It requires treatment with rhinitis medication under a doctor's guidance. If the medication has expired, some of its active ingredients may become ineffective, reducing the drug's therapeutic effect. Moreover, due to prolonged storage after expiration and possible improper storage conditions, the medication could become contaminated with bacteria. Using expired nasal medication in such cases may lead to infections within the nasal cavity, worsening symptoms or causing gastrointestinal discomfort, thereby aggravating the condition and increasing treatment difficulty.

It is recommended that patients with rhinitis use medications appropriately under medical supervision and always check the expiration date before use to avoid physical discomfort from expired drugs.
