Topical decongestant

Topical decongestants are decongestants applied directly to the nasal cavity. Their effectiveness by themselves in the common cold appears to have a small benefit in adults.[1]

Topical decongestants should only be used by patients for a maximum of 5–7 days in a row, because rebound congestion may occur in the form of rhinitis medicamentosa. When used in adults for a short period of time side effects appear to be few.[1]

Mechanism of action

Topical decongestants are vasoconstrictors, and work by constricting the blood vessels within the nasal cavity.

Examples
gollark: They seem like they would be very unethical, I agree.
gollark: I mean, if *I* had access to unfathomable cosmic power, I would ruthlessly exploit it for all it's worth.
gollark: You mean there are literally no other possible things? Or is this like that thing with the god where you refused to run my obviously good test of having them factorize semiprimes.
gollark: Yes.
gollark: You should eliminate it with magic.
