Iatrogenic rhinitis continues to be called "drug-related rhinitis".
Three classifications can be distinguished.
The first is called “rhinitis medicamentosa”. This rhinitis occurs after a prolonged use of nasal vasoconstrictive agents (drops containing a substance to relieve nasal blockage). Rhinitis medicamentosa is usually difficult to treat.
The second class is a consequence of local use of substances of abuse (e.g. sniffing of cocaine or glue).
The third class of iatrogenic rhinitis is induced after oral ingestion of medicinal products (ACE-inhibitors, beta-blockers, non steroidal anti-inflammatory drugs, oral contraceptives, aspirin etc.). For instance, in the case of a reaction to aspirin or related drugs, severe reactions can occur such as an asthmatic crisis.
The symptoms of iatrogenic rhinitis are typically, sneezing, runny nose or blocked nose.
The diagnosis is generally based on the case history.
