Question 1

does anyone know what the drug neo-synephrine does?

Accepted Answer

Neo-synehrine: Neosynephrine (phenylephrine) constricts blood vessels.  Given intravenously, it raises blood pressure and is used to treat low blood pressure or shock. Given topically or in small doses orally, it constricts the vessels in the nose (nasal mucosa) which opens breathing passages.

Question 2

what happens if a dose of neo-synephrine is missed?

Accepted Answer

Neo-synephrine: All topical nasal decongestants (afrin, Vicks inhaler, 4-way, neosynephrine etc.) if used daily can result in a form of addiction called rhinitis medicomentosa. This problem develops when the nasal tissues develop a resistance to the effects of the spray and more frequent use is needed to keep the nose open. Avoid using these products for more than 2 days without time away from them (3-4 days).

Question 3

does neo synephrine help you get over a cold faster?

Accepted Answer

Quick answer: No.  It relieves symptoms.  Unfortuantely continued use or use in the wrong person (i.e. With high blood pressure) could cause lots of other problems.

There are better medications for treating your chronic symptoms. See your doctor.
