Oxymetazoline (?) it is called, from Boots. Standard nasal decongestant spray for a horrid virus.
The bottle wasn’t producing anything when I squeezed it upright so had to angle it a little. Anxious now that I have indeed had too much of it. I definitely swallowed most of the 2 sprays worth as it went straight down the back of my throat - awful taste.
Health anxiety central over here. Happy to be told I’m overreacting. Logically I reason they wouldn’t sell a product for use in the nose without tolerance of some being swallowed, but there’s always the what if!
